RedMAX Base Station Overview
Congratulations on your purchase of the Redline Communications model Access Node100U wireless broadband base station single sector base station. Redline
Communications is a world leader in design and production of Broadband Fixed Wireless
(BFW) systems.
Introduction
The RedMAX base station is a carrier class IEEE 802.16-2004 compliant wireless device
for deployment of point-to-multipoint (PMP) and point-to-point (PTP) systems.
Figure 2: Intro - Base Station Terminal, Transceiver, and Antenna
The base station consists of an indoor terminal (IDU) and outdoor modem and antenna
(ODU). Each operational RedMAX wireless broadband network segment is comprised of
a RedMAX base station and one or more WiMAX Forum Certified subscribers. Each
subscriber registers and establishes a bi-directional data link with the base station sector
controller.
The RedMAX base station is (part of) the 802.16 definition of a base station. A RedMAX
base station functions as a central hub or concentrator, connected to a WAN network
access point, and managing wireless links for remote subscribers. The RedMAX base
station enforces the Quality of Service (QoS) settings by controlling all uplink and
downlink traffic scheduling -- providing non-contention based traffic with predictable
transmission characteristics.
2.2
IEEE 802.16 / WiMAX Compliance
The IEEE 802.16-2004 specifications describe a PMP broadband wireless access
standard for systems operating in the frequency range of 2-11 GHz, and 10-66 GHz. This
standard includes descriptions for both the Media Access Control (MAC) and the
physical (PHY) layers.
The RedMAX base station is compliant to the following IEEE 802.16-2004
WirelessMAN-OFDM and WirelessHUMAN-OFDM Physical Layer Profiles:

- ProfP3_3.5: WirelessMAN-OFDM PHY profile for 3.5 MHz channelization (Rel. 1.0)
- ProfP3_7: WirelessMAN-OFDM PHY profile for 7 MHz channelization (Rel. 1.1)
Note that the 802.16 standards are subject to amendment, and RedMAX product design
compliance applies to a specific revision of the standard. The RedMAX product does not
support mesh communication (direct subscriber-to-subscriber).
Redline is an active member of the IEEE 802.16 standards committee and has been
instrumental in creating the original 802.16 standards. Redline is also active in
recommending, writing and following-up on new amendments to the 802.16
specifications.
Redline is an active member of the WiMAX Forum™ and is participating in
interoperability testing in the WiMAX Forum.
2.3
PHY Specification
The base station is designed for 2-11 GHz operation based on the WirelessMAN-OFDM
PHY definition in the IEEE 802.16 specification. Refer to the system specifications for
supported frequency ranges.
2.4
OFDM (256 FFT)
The base station uses Orthogonal Frequency Division Multiplexing (OFDM). OFDM is a
multi-carrier transmission technique where the data stream is split and transmitted (at a
reduced rate) in parallel streams on separate sub-carriers. OFDM uses the Fast Fourier
Transform (FFT) algorithm to implement modulation and demodulation functions. Using
adequate channel coding and bit-interleaving, OFDM can perform very well in severe
multipath environments, mitigate frequency selective fading and provide high spectral
efficiency.
2.5
2.5.1
Features
Privacy
The base station is hardware ready to provide encryption for user traffic. The MAC
header of 802.16 contains the information Encryption Control (EC), Encryption Key
sequence (EKS) , and Connection Identifier (CID) necessary to decrypt a payload by the
receiver. Protection of the payload is indicated by the EC bit field. A value of '1' indicates
the payload is cryptographically protected and the EKS field contains meaningful data. A
value of '0' indicates the payload is not cryptographically protected. The EKS field
contains a sequence number used to identify the current generation of keying material.
2.5.2
Time Division Duplexing (TDD)
The base station system uses time division duplexing (TDD) to transmit and receive on
the same RF channel, or using separate RF channels using half-duplex FDD (HD-FDD).
These are both non-contention based methods for providing an efficient and predictable
two-way PTP or PMP cell deployment. All uplink and downlink transmission scheduling
is managed by the base station. The base station sends data traffic to subscribers, polls for
grant requests, and sends grant acknowledgements based on the total of all traffic to all
subscribers.

2.5.3
Coding Rate
Each burst of data transmitted over the wireless interface is padded with redundant
information, making it more resistant to potential over-the-air errors. The coding rate is
the ratio of user data to the total data transmitted including the redundant error correction
data. The base station supports coding rates of 1/2, 2/3, and 3/4.
2.5.4
Modulation
The modulation technique specifies how the data is coded within the OFDM carriers. The
base station supports BPSK, QPSK, 16 Quadarature Amplitude Modulation (QAM), and
64 QAM modulation.
2.5.5
Reed Solomon Error Correction
Outer Reed-Solomon and inward Convolution Coding (RS-CC) error correction is
enabled for all traffic rates, with the exception of BPSK 1/2 where only inward
Convolution Coding is used. These low-level processes can correct bursts of errors in
received messages and reduce the number of retransmissions.
2.5.6
Time Synchronization
When operating two or more collocated base stations, transmitter operations MUST be
synchronization to minimize inter-sector interference. Each base station has a
synchronization port located on the front panel to receive synchronization pulses.
2.6
Deployment Models
The base station supports point to point (PTP) and point to multipoint (PMP) deployment
scenarios.

2.6.1
PTP Deployment
When deployed in a PTP configuration the base station establishes a dedicated bidirectional link to a single subscriber. The PTP deployments typically use a directional
narrow beam antenna for both ends of the link.
2.6.2
PMP Deployment
When deployed in a PMP configuration the base station establishes bi-directional links to
more than one subscriber. PMP deployments typically use a wide beam (sector) antenna
at the base station and a narrow beam antenna at the subscriber. Service flows are used to
police service level agreements for each subscriber.
2.6.3
Non Line-of-Sight
The RedMAX system supports line-of-sight (LOS), optical line-of-sight (OLOS), and
non line-of-sight (NLOS) operation. A clear LOS link has no obstacles within 60% of the
first Fresnel zone of the direct path. An OLOS link has obstructions within 60% of the
first Fresnel zone, but a visible path exists between the base station and subscriber. Refer
to the following illustration.
Figure 4: System - Fresnel Zone
A wireless link is considered non LOS if natural or man-made structures block the visible
path between the base station and the subscriber. In this case, a wireless link can be
established only if a reflective path can be established between the base station and
subscriber.

Channelization
The base station is a frequency-specific system, with the frequency band defined by the
modem unit. The use of the operating band must be in accordance with European
Conference of Postal and Telecommunications Administrations (CEPT)
Recommendation 14-03.
The base station divides the available frequency band into channels. Allocation of
channels during deployment is dependent on spectrum availability in the licensed FWA
band and local licensing requirements and conditions. Channel selection allows planners
to obtain the maximum geographic coverage, while avoiding frequency contention in
adjacent sectors.
2.7
Service Flows
Service flows are a key feature of the 802.16 standard.
A service flow represents a unidirectional data flow. Transmitting bidirectional traffic
requires that two service flows be defined: one for the uplink, and another for the
downlink. These service flows can have different QoS settings.
The base station allows multiple service flows to be configured for each subscriber in a
sector. This allows service providers to offer different services, and segregate traffic
flows having different QoS requirements.
A service flow is partially characterized by the following attributes:
1. A 32-bit Service Flow ID (SFID) is assigned to all existing service flows. The SFID
serves as the principal identifier for the Service Flow and has an associated direction.
2. A 16-bit Connection ID (CID) is associated with each active SFID (connection
active).

A set of QoS parameters specifying the required resources. The principal resource is

A set of QoS parameters defining the level of service being provided.
Service Flow Classification
Data packets are forwarded based on classification rules. Classification rules require
examining each packet for pattern matches such as destination address, source address, or
VLAN tag. All classification is defined at the base station and the classification
parameters are downloaded to the subscriber.
2.7.2
Dynamic Service Addition
Service flows are defined and stored in the base station. For each service flow to be
established, the base station sends a setup message to the subscriber specifying the
required set of QoS parameters. The subscriber responds to each request by accepting or
rejecting the setup message.
A service flow may be pre-provisioned or can be dynamically created and deleted
without service outage. This is useful for supporting multiple subscribers in a single
sector. New subscribers can be added and existing subscribers can be removed or have
service levels modified.
Setup messages are sent by the base station following any subscriber power-cycle, loss
and recovery of the wireless link to a subscriber, or any service flow add/delete operation
at the base station.
2.7.3
Default Service Flows
Default UL/DL service flows are created automatically for each registered subscriber.
These service flows are used to pass all traffic not matching any user-defined service
flow (such as broadcast ARP) between the base station and subscribers. The default
service flow capacity is limited for each subscriber.
2.7.4
Scheduling
The base station enforces QoS settings for each service flow by controlling all uplink and
downlink traffic scheduling. This provides non-contention based traffic model with
predictable transmission characteristics. By analyzing the total of requests of all
subscribers, the base station ensures that uplink and downlink traffic conforms with the
current service level agreements (SLAs). Centralized scheduling increases predictability
of traffic, eliminates contention, and provides the maximum opportunity for reducing
overhead.
A regular period is scheduled for subscribers to register with the base station. These
subscribers may be newly commissioned or have been deregistered due to service outage
or interference on the wireless interface. This is the only opportunity for multiple
subscribers to transmit simultaneously.
Real-Time Polling Service (rt-PS)
The base station schedules a continuous regular series of transmit opportunities for the
subscriber to send variable size data packets. The grant size is based on the current data
transfer requirement. Typical applications include streaming MPEG video or VOIP with

silence suppression. This is efficient for applications that have a real-time component and
continuously changing bandwidth requirements.
Non-Real-Time Polling Service (nrt-PS)
The base station schedules regular transmit opportunities for the subscriber to send
variable size data packets. Typical applications may include high bandwidth FTP. The
polling period may typically be one second or less, even during periods of network
congestion.
Best Effort (BE)
The base station schedules transmit opportunities for the subscriber to send traffic based
on unused bandwidth after all higher level traffic scheduling requirements are serviced.
Typical applications may include Internet access and email. Best effort service flows can
be assigned a priority of 0 to 7.
Unsolicited Grant Service (UGS)
The base station schedules a continuous series of transmit opportunities for the subscriber
to send fixed size data packets. This schedule supports real-time applications including
VoIP or TDM transport. The UGS pre-scheduled grants guarantee reserved bandwidth
and reduce latency introduced by repetitive grant requests. The service flow will not
transmit packets larger than nominal grant interval.
Traffic Scheduling Algorithm
The base station scheduling algorithm uses two scheduling passes. On the first pass, the
scheduler attempts to allocate bandwidth to meet the minimum rates for all active service
flows. If there is available bandwidth remaining at the end of the first pass, the scheduler
executes a second pass and attempts meet all specified maximum rates. During both
passes, bandwidth allocations are assigned based on the following order of assessment:
1. Priority of the scheduling service type, from highest to lowest (rtPS first, and then
BE).
2. Traffic Priority setting when multiple service flows have the same service type.
Wireless transmission bandwidth is optimized by granting allocations based only on
traffic available for immediate transmission: only the required bandwidth is allocated,
and idle service flow channels do not receive any bandwidth allocation.

Creating Service Flows - Overview
There are four steps associated with creating service flows:
Note: A service class can not be deleted until all provisioned/active service flows
referencing this service class have been deleted.
1. Create service class.
Each service class defines a set of QoS parameters that can be associated with a
service flow. Multiple service class definitions can be added to create a library of
service classes. By creating a set of standardized service classes, new service flows
can be added that conform to pre-defined service level agreements (SLAs). Each
service class definition includes traffic rates, latency settings, priority, and
transmission policy settings.
2. Create service flow.
All service flows are based on existing service class definitions. Separate service
flows are required for downlink and uplink traffic. Each definition requires
identifying the subscriber, flow direction, class of service, and the classifier type.
3. Define classifier.
A unique set of classifier rules can be defined for each service flow, depending on the
classification type (i.e., Packet, 802.3/Ethernet) selected when the service flow is
created. All associated classifiers are deleted when the service flow is deleted.
4. Activate
A new service flow is not activated until a classifier is assigned (click Add in the
Classifier screen).
If the target subscriber is registered a Dynamic Addition Session (DSA) session is
initiated. During a DSA session, the service flow is in Requesting state. If the DSA
session is successful, the state is set to Active. If the DSA session is not successful, the
state is set to Rejected.
If the target subscriber is not registered, the service flow request is stored until the
associated subscriber is registered. The subscriber registration triggers the activation
of all associated service flows.

Click Service Flows in the menu (left side of screen) to view, add, and delete service
flows. Service flows provide the ability to set up multiple uplink and downlink
connections to each subscriber in a sector, and each service flow may be assigned a
unique service level category and separate QoS settings. A service flow is not fully
activated until at least one classifier is assigned.
Default UL/DL Service Flows
The default service flows are used to pass traffic not matching any user-defined service
flow (such as broadcast ARP) between the base station and subscribers. The default
downlink service flows can not be disabled. A single setting enables or disables (default)
the default uplink service flows for all subscribers in a sector.
Important: When dynamic MAC Learning is enabled (see 4.3.1: Subscribers on page 44)

Classifiers
Click Classifiers in the menu (left side of screen) to view, add and delete service flow
classifiers. Any active service flow must have at least one active classifier. The 802.16
Service Flow can have multiple classifiers (classification rules). New classifiers become
active after clicking the Add button on this screen.
When multiple classifiers are defined for one service flow, the index number is listed in
the form X.Y where:
X == Service Flow index (SfId)
Y == Classifier index number
When a service flow is activated, the classifiers become active by default. A service flow
can have both active and inactive classifiers only when the service flow is already active
and new classifiers are added. New classifiers become active only after they are
successfully implemented on both the base station and the subscriber.

DHCP Relay Agent Parameters
The subscriber can obtain an IP address from the DHCP server only through an base
station acting as a DHCP Relay Agent. A subscriber can not obtain an IP address from
any DHCP server on the network segment connected to its local Ethernet port. The base
station (acting as a DHCP Relay Agent) can be configured for two different modes:
SS-s should use the same DHCP Server as SC: Select this option to have the base
station forward all subscriber DHCP requests to the DHCP server that the base station
used to obtain its IP address (valid only if field Obtain IP Parameters from DHCP Server
is enabled above).
SS-s should use the following DHCP Server: Select this option to specify the DHCP
server to be used by subscribers.
DHCP Server: Specify the IP address of a DHCP server. The base station forwards
all subscriber DHCP requests to this address.
It important to configure the correct lease options on your DHCP Server:
a) The base station requires option 4, the address of a ToD Server (RFC-868).
b) If you do not wish your devices to display GMT, you must add option 2 (Time Offset).
This is a value denoting the number of seconds to offset your time from GMT. For
example, for the offset of +2 hours you should enter 7200 (some DHCP servers may
require entering hexadecimal value). In North America, EST is -5 hours (-18000 seconds)
from GMT and the negative value must be entered.
Important: The base station must be rebooted to activate changes to the DHCP Relay
Agent settings.
VLAN Management
Enable Management with VLAN Tagged Traffic: Check
this box to enable
management using VLAN tagged traffic for the SM CID. This setting is used to
configure tagged management for operation in systems where a single VLAN is used to
control the base station wireless equipment and the user equipment. After enabling this
setting, only traffic with the specified VID is recognized for any management commands.
This setting does not effect operation of the RS-232 Console port.
VLAN ID: Enter the VLAN ID. Only traffic tagged with this VLAN ID is recognized by
the sector controller management process.
Important: The VLAN network support should be verified before enabling this feature.
If the base station is not reachable using the VLAN tagged traffic, the Console port
(RS-232) CLI command must be used to disable this setting.
Save: Click Save to save and apply the current settings.

Modulation is disabled the base station will receive data from subscribers only using the
selected modulation/coding.
Thresholds: Enter the adaptive modulation threshold values (dB) for each modulation
(based on measured CINR). The values are used only when Adaptive modulation is
enabled. There are two entry fields for each threshold setting (row):
- Minimum Entry Threshold (right column)
- Mandatory Exit Threshold (left column)
The modulation/coding is decreased by one step under the following conditions:
1. CINR drops below the exit threshold of the current CINR
2. CINR is between the entry threshold and exit threshold of the current UIUC and CRC
errors are detected in the uplink channel
Settings must be adjusted to match the characteristics of each deployment. Refer to the
following table for recommended threshold settings. These are applicable for independent
sector operation. Co-channel sector deployment in a cell may require further optimization
of the Adaptive Modulation settings.

User Manual
Backoff settings are used when a subscribers experience collisions during link
establishment or while competing for additional bandwidth. The entered value represents
the binary exponent of the number of 'opportunities' to wait before responding to a base
station registration poll or a bandwidth request opportunity.
It is recommended to not change the Backoff values. Changes to these settings can
severely impact performance of the wireless link. Click the Default button in the
Advanced Config menu to restore the factory backoff settings.
Ranging Backoff Start: Enter the starting backoff window size for initial ranging
contention.
Ranging Backoff End: Enter the final backoff window size for initial ranging
contention.
Request Backoff Start: Enter the starting backoff window size for contention during
bandwidth requests.
Request Backoff End: Enter the final backoff window size for contention during
bandwidth requests.
Save: Click Save to apply and save the displayed settings. Changes to settings marked
with a red asterisk (*) are effective only after the base station is rebooted.
Cancel: Click Cancel to discard all changes and return to the main screen.
Default: Click Default to set all settings to the factory default settings.
Example: How Subscribers Use Backoff Settings
When a subscriber detects a collision during a registration attempt, the subscriber will use
a retry strategy to avoid repeating the collision. Consider the effects of the following
settings:
Ranging Backoff Start = 2
Ranging Backoff end = 4
Following a collision, the subscriber will skip between zero and four registration
opportunities (2Ranging Backoff Start). If the subscriber detects a collision during the retry, it
will skip a random number, between zero and eight registration opportunities (2Ranging
Backoff Start+1
). If a third collision is experienced, the subscriber will skip between zero and
sixteen registration opportunities (2Ranging Backoff End). If a fourth collision is detected, the
process repeats as for the first detected collision.

Operational Notes
6.1
Self-Provisioning Features
6.1.1
Default Service Flows
The base station automatically creates one default uplink and downlink service flow for
each registered subscriber. The default service flows pass initial traffic (i.e., DHCP
Discovery or PPPoE Initiation) from hosts connected to subscriber. The default service
flows have the lowest QoS settings and the associated classifiers have the lowest priority.
The sector-wide bandwidth is limited to 64 Kbps downlink and 8 Kbps uplink. Traffic
statistics are reported aggregate with all other service flows. The default service flows
and classifiers must be included when calculating the total service flows and classifiers
for a sector.
6.1.2
Pass-All Classifier
The 802.3 classifier can be configured to allow unfiltered Ethernet traffic in the direction
of the associated service flow.. Configure a classifier to 'pass-all' by setting the MAC
address to zero. For example,
SrcMacAddr:
00:00:00:00:00:00 .
DestMacAddr: 00:00:00:00:00:00 .
Note: Only one subscriber in a sector may have a downlink service flow classifier
configured as 'pass-all'. All uplink traffic is subject to filtering by Automatic UL filtering
and the host Learning feature (if enabled).
6.1.3
Automatic UL Filtering
The Automatic Uplink filter implemented at the subscriber emulates bridge functionality
to prevent local traffic from being transmitted upstream over the wireless interface.
6.1.4
Host Learning
The MAC learning feature allows the base station to automatically learn the MAC
addresses of up to sixteen hosts (devices) on the Ethernet segment connected to a
subscriber. The learning feature can be enabled individually for any subscriber and the
number of learned hosts can be adjusted dynamically.
The subscriber learns MAC addresses on a first-come basis. The subscriber does not age
the learned MAC addresses -- table is re-learned only when the subscriber is rebooted.
Note: Enabling host learning affects the function of downlink 802.3 classifiers (see
Generic 802.3 DL Classifiers following). No other classifiers are affected.

Generic 802.3 DL Classifiers
When host learning is enabled, 802.3 classifiers created for downlink service flows will
be 'generic' type. The generic type 802.3 classifier allows all downlink Ethernet traffic
addressed to any of the learned hosts on the associated subscriber. Only the priority may
be adjusted on generic 802.3 classifiers.
6.1.6
DHCP Option 82
The DHCP option 82 support can be used by equipment upstream of the RedMAX base
station to uniquely identify when customer equipment located behind a subscriber issues
a request for network access (DHCP request for an IP address). This information, used in
combination with other network notification messages, allows network operators to be
informed when customers activate self-install CPEs. Operations can then take manual or
automated actions to authorize and activate the services for this subscriber.
The format of Relay Agent Option 82 option is as follows:
Circuit ID: MAC address of base station.
Remote ID: MAC address of subscriber.
GiAddr:
Management IP address of base station (if added by upstream
equipment).
Note: The subscriber CLI control 'dhcpRelayAgent' must be enabled prior to using the
Option 82 feature.

6.2.1
Privacy Layer -- Encryption
Overview
All RedMAX equipment is hardware enabled to support the privacy sub-layer as defined
in 802.16-2004. The process of modem authentication and message exchange for user
traffic encryption is described fully in the 802.16-2004. The Privacy Sub-layer can be
enabled on a individual subscribers. This release supports user traffic encryption through
the DES cryptographic suite only, with the Traffic Encryption Key secured to a 3DES
level. Encryption must be enabled separately for the AN-100U and each participating
subscriber.
Authentication and registration are part of the 802.16 MAC common part sublayer.
Authentication is based on the use of PKI technology-based X.509 digital certificates.
Each wireless subscriber access modem will contain one built-in certificate for itself and
another for its manufacturer. These certificates allow the customer modem to uniquely
authenticate itself with the base station. The base station can then verify that the customer
modem is authorized to receive service. If the database lookup succeeds, the base station
sends the customer modem an encrypted authorization key, using the customer modem’s
public key. This authorization key is used to encrypt and protect any transmissions that
follow.
The authentication process ensures the subscriber modem is an authentic device and not a
rogue that was brought into the wireless sector area. For authentication the devices use
X.509 digital certificates [IETF RFC 3280] together with RSA public-key encryption
algorithm. At the end of the authentication, process the device has a shared key with its
peer known as AK (Authentication Key). This Key is used to derive the TEK.

User Manual
Management messages between AN-100U and subscriber modem are protected with a
HMAC digest that ensures the data was not altered over the air in any way. The
authenticity of the CA's signature, and whether the CA can be trusted, can be determined
by examining its certificate in turn. This chain must however end somewhere, and it does
so at the root certificate, so called as it is at the root of a tree structure. Root certificates
are implicitly trusted. Redline Root CA certificate is issued by Verisign. It can be uses to
validate the certificates of the subscriber modem and cannot be used to validate the
certificates supplied by another vendor.
Authentication Using Digital Certificates
The entire authentication process is performed inside the AN-100U and it does not
require external AAA servers (e.g. RADIUS, TACCACS, LDAP, etc). On AN-100U
there is a space of 64 Kbyte of memory reserved for X509 Root CA certificates. A root
certificate allows the validation of subscriber modem certificates.
Validation process implies a check of the certificates against the information stored on
the AN-100U. The result of this check is a truth value based on which the AN-100U will
allow the subscriber to join the network. There are two scenarios:
1. Base station can skip the validation of the certificates sent from subscriber and
performs only a basic test to ensure is properly encoded.
2. Base station checks the digital signature with the information stored on the board.
To switch between the two scenarios the operator modifies the field TrustAll under
"privacy" group.
6.2.2
Configuring Privacy
This section describes the CLI commands for Privacy sublayer functions. Settings for
privacy modules are defined under "privacy" group. The values set by the user are taken
into account only after a system reset, even though the values are stored into NVRAM
memory immediately. The privacy module on the AN-100U always running, while the
subscriber modem can be enabled or disabled.
X509 Root CA Certificates
Each subscriber modem shipped from the factory comes with two X509 certificates subscriber modem certificate and CA certificate. The subscriber modem certificate is
unique per subscriber modem sends the certificates to the AN-100U during network entry
procedure in order to authenticate itself. The AN-100U verifies the certificates are valid
and allows or denies the subscriber request to join the network.
Privacy Sublayer Settings
This section is AN-100U specific and describes CLI support to manipulate X509
certificates. The commands are available under "x509" group.

a reboot. The two keys are replaced at regular time intervals as specified by their
corresponding lifetimes. The operator can also specify to trust all subscriber certificates
or to validate each subscriber based on stored root certificates. There are two modes:

Co-Channel Operation
Greater complexity in the modulation technique requires a greater (C/N) ratio to
maintain adequate throughput. In the presence of an interferer, the useful signal is
degraded. The ratio of 'useful signal' to 'interfering signal' is called the carrier-tointerference ratio. If the interferer signal power is additional noise power, and the overall
C/I+N ratio can be estimated as:
CINR = C / I +C / N − 10 log(10

User Manual
This formula corresponds with an expectation that a very strong signal (high C/N) is able
to withstand higher levels of interference (low C/I). If the signal is weak, even low
interference levels will significantly degrade the useful signal. Consider the following
examples:
Case 1: The threshold CINR for 64 QAM 3/4 is around 23.25 dB. If the C/N ratio is 24
dB, the system will operate at 64 QAM 3/4 (signal is close to the 64 QAM 3/4 threshold,
but still above it). If we introduce an interferer with a signal 30 dB weaker than the
system signal (i.e., C/I = 30 dB), the overall CINR will drop to around 23 dB, forcing the
system to change the modulation rate to 64 QAM 2/3.
Case 2: If the signal is very strong and the C/N ratio is around 28 dB, it will require a
much stronger interferer to force a drop in modulation. According to the formula above,
for a C/N of 28 dB, the C/I should be 25 dB in order to force a drop in modulation. In this
case the interferer was 5 dB stronger than the first case.
The following table lists experimentally obtained minimal C/I ratios required for the
system to not change modulation:

In case 1 the signal is already very close the threshold rate (C/N is less than 1 dB above
the CINR threshold) and even weak interference can force the system to change to a
lower modulation. A moderately high C/I ratio is required for the modulation to remain
unchanged.
In case 2 the signal is very strong (C/N is more than 10 dB above the CINR threshold)
and can experience more severe interference without being forced to change modulation.
The amount of interference required to force the system to go to the lower modulation
rate in these two extreme cases is very different, and in an actual deployment scenario a
full range of results are possible. Careful planning is necessary when frequency reuse is
required, and sufficient fade margin must be included to anticipate fluctuations of both
C/I and C/N.

Interference Issues
6.4.1
Multipath Interference
The base station is designed with high immunity to interference and multipath signals. Its
core technology is Orthogonal Frequency Division Multiplexing (OFDM), capable of
reliable performance under multi-path and frequency selective fading known to have
severe signal fading and distortion effects in the sub-11 GHz frequencies.
Multipath interference is a significant problem in long-range links, and in near line-ofsight, and non line-of-sight links. Multipath is a form of self-interference occurring when

RedMAX™

User Manual
signal reflections arrive slightly later than the primary signal. The result can be
destructive interference that can essentially null out the primary signal or overlap the
original signal such that it cannot be decoded. Multi-path interference is a problem with
long-range links where reflections off the ground, snow, and water frequently interfere
with the primary signal. It is also a problem in urban environments where the signal
reflects off buildings, trees, and roads.
OFDM breaks up the transmit signal into many smaller signals. For example, instead of
one single carrier carrying 70 Mbps of data (wireless interface rate), there are 192
separate carriers, each carrying about 364 Kbps of data (in the case of the Redline
product) in a 14 MHz bandwidth. If selective fading degrades one or two carriers, the
impact is minimal since the information is spread across the remaining carriers.
Figure 36: Op Notes: OFDM Multiple Carriers
One key aspect of OFDM implementation is that the individual carriers overlap
significantly to preserve overall bandwidth. Normally, overlapping signals would
interfere with each other, however, through special signal processing, the carriers in an
OFDM waveform are orthogonal to each other.
Multipath interference may cause individual narrowband channels to be altogether lost.
This problem is addressed in the Redline implementation in three ways:
1. Equalizing the received signal based on an estimate of the channel fading conditions
(restoring the faded sub-channels).
2. Interleaving the data before modulation onto the individual sub-channels (so that
adjacent data symbols do not necessarily end up on adjacent sub-channels, and thus
deep fades do not impair large chunks of the signal).
3. Convolutional encoding of the input data introduces correlations between signal
samples that are echoed on sub-channels occurring in separate parts of the spectrum.
This allows the receiver to infer the values of the signal that were transmitted on
fatally faded sub-carriers. The key advantage of multiple carriers is that the signal is
more robust to multipath disturbance, as described below.
OFDM equalization and coding techniques cannot overcome all forms of sharp,
multipath-related fading. For additional robustness, the OFDM implementation uses a
guard interval between each of the sub-channels. This guard interval is filled with
redundant data taken from the end of the same channel symbol and repeated at the
beginning of each channel symbol. Multipath echoes from each individual sub-channel
overlap the guard interval, rather than overlapping data in other symbols. Used in

conjunction with adaptive equalization, coding, and modulation, use of the guard interval
provides reliable operation in a wide class of non line-of-sight environments.
6.4.2
Calculating Receive Sensitivity (WiMAX Testing)
Overview
The WiMAX test for receive sensitivity modifies the methodology from 802.16 to allow
results to be obtained easier and faster. The standard Bit Error Rate (BER) of 1x10-6
remains the benchmark for these calculations. The BER is obtained by measuring Packet
Error Rate (PER), but PER cannot truly be measured (it is a limit) and requires that a test
be performed to estimate the PER value. Larger sample sizes will produce more accurate
values for PER. There is a practical limit to the size of the test sample, and WiMAX has
chosen the number of packets in the sample to enable result that will approximate a BER
lower than 1x10-6.
Sample Test for Subscriber Receive Sensitivity
1.
Connect packet generator to the base station-to-subscriber link and then configure
packet generator to send 50,000 Ethernet packets with payload of 288 Bytes (i.e.,
total Ethernet packet size is 288 + 18 = 306 Bytes). Payload should not be chosen by
the packet generator, but must be filled with the pattern defined in the WiMAX
standard. The packets should be sent at a rate to fill at least 80% of the downlink
(DL) frame.
2. Count the number of packets received. If less than 97 packets are lost, it can be
stated with 95% confidence that the BER is 1x10-6 or lower.
3. Repeat the test by sending 20,000 Ethernet packets with payload of 864 Bytes. If less
than 118 packets are lost, it can be stated with 95% confidence that the BER is 1x106 or lower.
4. You repeat the test by sending 10,000 Ethernet packets with payload of 1488 Bytes.
If less than 100 packets are lost, it can be stated with 95% confidence that the BER is
1x10-6 or lower.
5. Receiver sensitivity is defined as the lowest RSSI value tested where samples for all
three packet sizes did not exceed the maximum number of lost packets. The 95%
confidence level indicates that if the test is repeated multiple times, you will obtain
passing results 95 times out of 100.
Refer to the following table for a summary of the test parameters.

General Interference
Redline has introduced several techniques into its products to mitigate interference
issues:
1. OFDM: multiple carriers using both time and frequency diversity to provide high
tolerance to co-channel and adjacent channel interference, remove ISI due to
multipath and recover data from carriers falling in regions of deep channel fades.
2. Multiple channels (twenty-eight non-overlapping at 3.5 MHz) for diversity and
interference mitigation.
3. Adaptive modulation using six transmission rates to suit varying link conditions.
4. Adaptive encoding is heavily coded to substantially increase robustness. State of the
art FEC using Convolutional-coding gives the base station superior frequency
selective fading mitigation capability.
5. Narrow beam antennas with high side lobe and backlobe isolation and very low
VSWR.
6. Antenna cross-polarization enabling equipment co-location as well as effective
frequency planning.
7. High receiver dynamic range to address dynamic interference.
8. State of the art filtering at the RF, IF and baseband levels to reduce interference.
9. Choice of non-adaptive modulation to provide stable burst rate during periods of
rapid interference variations on the link.

7.1
Secondary Management Channel (SMC)
The SMC has a higher priority than data in downlink, but the maximum rate is limited to
512 Kb/s in normal operation. During SMC maintenance intervals, the rate is unlimited to
allow faster FTP transfers over SMC. The SMC maintenance interval can be enabled by
the Redline Management Suite (RMS). In uplink the first 32 Kbps of the SMC traffic has
a higher priority than data, and the remaining SMC traffic has lower priority.
7.2
Time Synchronization
When operating two or more collocated base stations (BSs), transmitter operations
MUST use synchronization to minimize inter-sector interference. Refer to the RedMAX
Base Station Installation Guidelines for complete details.

Front Panel Diagnostics
Figure 37: Diagnostics: Base Station Front Panel View
7.4.1
System LEDs
The front panel of the terminal includes a number of LEDs to monitor operation of the
system and assist troubleshooting. Refer to section 3: Physical Description on page 25.
7.4.2
Console Port
The front panel includes the Console port. Use the CLI commands to interrogate the base
station status and program most system settings.
7.4.3
System Reset Switch
Throughout this section, reference is made to the reset switch, which is a micro-switch
recessed in the front panel in the system block. Use a small narrow object, such as a
paper clip, to access the switch.
Depressing the reset switch for less than five seconds activates a short-reset. This is
equivalent to turning the terminal off and on. Statistical values are reset. The selected
system software image is loaded.
Depressing the front panel reset switch for more than five seconds activates a long-reset.
A long-reset reloads the factory defaults for the IP Address, IP subnet mask, and
password and then resets the system. Statistical values are reset. The selected system
software image is loaded.
7.5
Recovering a Lost IP address
Use a DB-9 serial cable to access the base station serial console. The configuration of the
serial port should be 57,600 bps, no parity, 8 data bits, 1 stop bit. Once connected, type in
the command ifShow and read the value of inet under the idt interface.
7.6
Detecting Channel Interference at Startup
Following a power-cycle or reboot, the base station monitors the RF Channel to detect
interference on the uplink channel. The transceiver is set to receive mode and the PHY is
programmed to receive a long preamble from a WiMAX base station. If no preamble is
detected during the one-second interval, the channel is considered free of interference
from other WiMAX equipment.
If a long preamble is received, the base station continues to monitors the channel for an
additional three seconds. If an 802.16d DL-Map is received, the following message will
be entered into the event log:
WARNING: RF Channel Conflict with [BS Id]
This message in the event log indicates that another base station has been detected using
the following RF-PHY characteristics:

- Same DL channel frequency as the UL channel frequency of this SC
- Same Cyclic Prefix

If a long preamble was received, but no DL-Map was detected, the following message
will be entered into the event log:
WARNING: Unknown Interference was detected on the UL channel
This second message does not necessarily indicate interference from another base station,
and may be the result of cross-interference from subscribe stations.
7.7
Re-Ranging Log Message
The log message 're-ranging' is recorded by the base station when a registered subscriber
initiates a network entry sequence.
There are two common reasons for this event:
1. When network entry is complete, the subscriber retains its 'registered' state by
sending data traffic to the base station. When there is no data traffic, the SU-O sends
only periodic ranging requests each 25 seconds. Under no-traffic conditions, it may
take the base station more than 25 seconds to declare a subscriber unavailable and
mark it as de-registered. During the same 25 second period, the subscriber may
declare the base station to be unavailable (i.e., due to poor link conditions) and begin
attempts to re-register. In this scenario, the subscriber is attempting to re-register
before the base station has declared the subscriber to be failed.
2. This condition may also result from a loss of connectivity between a subscriber and
the DHCP server or TOD server. When remote management is enabled on the
subscriber (managedSS=1), the subscriber must communicate with the DHCP server
and the ToD server specified in the obtained lease. If communication cannot be
established within two minutes, the subscriber will reset and repeat the attempt.
7.8
Troubleshooting the Web Interface
These troubleshooting steps assume that the status LEDs on the front panel of the
terminal indicates normal function.
1. Open a Web browser and attempt to login to the base station terminal. If the terminal
does not respond by displaying the login dialog box, check that the correct IP address
is being used. The factory default address is listed in the Troubleshooting section.
The IP address may have been changed during installation. For correct operation the
host computer and the terminal must appear to be on the same subnet. Ensure that the
IP address for the PC is set to the same subnet as the terminal. For example, the IP
address should only differ in the last octet (i.e., 192.168.101.X).
2. The next test is to verify the IP address is reachable from the computer. Use the ping
command to test the connection between the terminal and host computer. The system
always responds to ping frames less that 577 bytes in length.
If the ping test is successful the host computer was able to send and receive packets.
The problem may be with the Internet browser or related settings on the host
computer. Re-boot the host computer to try to resolve the problem.

If the ping is not successful, the IP address may be incorrect, or a duplicate address
may exist.
3. If the current address of the terminal cannot be determined, it is recommended to
perform a long-reset. Performing a long-reset restores the terminal IP address and IP
Subnet Mask to the factory default values. Note that this operation may discard some
custom settings.

7.9
Solution
Perform a ping test from the host computer
command line. If the ping test is unsuccessful,
then the problem is with the IP address. Perform
a long-reset to restore the default address.
If the ping is successful, reboot of the base
station and/or host computer.
Run 'arp -d' whenever connecting to a different
base station terminal. Check that the subnet
mask for the host PC matches the subnet mask
of the terminal. Check that the host PC address
is in the same subnet.
Replacing the System Fuse
Important: Always completely remove power from the base station before performing
any maintenance on the terminal or modem.
Warning to service personnel:
Caution for all AC and DC models – Double Pole/Neutral fusing.
To replace fuse:
1. Disconnect power from the terminal.
2. Pry off the black plastic cover located on the back panel beside the power switch and
extract the red fuse holder.
3. Use an approved tool to remove the glass-cased fuses from the holder.
Be certain to replace the fuse(s) into the lower half of the holder, as shown in the
diagram below. The fuse holder holds two fuses, both of which are active. Be certain
to use fuses of the same type and rating.
4. Replace the fuse holder in the system terminal and secure.
5. Restore power to the base station.

DC Power Connections
This section provides important instructions for connecting to a DC power source.
The DC power supply (optional) is rated for operation from 21 to 60 volts DC.
Warning to service personnel:
Caution for all AC and DC models – Double Pole/Neutral fusing.
Power is supplied to the terminal using a fused power entry module. All DC terminals are
shipped with a one-meter power cord assembly, consisting of the power entry module’s
mating dual pin polarized female plug pre-crimped with 18 AWG blue and black
insulated wires. If the wiring needs to be extended a minimum of 18 AWG wire must be
used.
The DC power input is floating (+Ve and -Ve not connected to chassis), allowing positive
(minus to ground), negative (plus to ground), and floating power connections as required.
Refer to table below for connection details.
If the terminal does not power on, it is possible that the blue and black wires are
connected incorrectly resulting in a reversal of polarity. In this event, the diode protection
prevents permanent damage to the power supply. Reverse the power connections and
verify that the terminal powers up properly.

The nrt-PS is designed to support non real-time service flows
that require variable size Data Grant Burst Types on a regular
basis, such as high bandwidth FTP. The service offers unicast
polls on a regular basis, which assures that the flow receives
request opportunities even during network congestion. The
RedMAX base station typically polls nrt-PS CIDs on an
interval (periodic or periodic) on the order of one second or
less. The key service elements are Minimum Reserved Traffic
Rate, Maximum Sustained Traffic Rate, Request/Transmission
Policy, and Traffic Priority.
A clear direct path between two antennas, with obstructions
within the first Fresnel zone.
Orthogonal frequency-division multiplexing (OFDM) is a
method of digital modulation in which a signal is split into
several narrowband channels at different frequencies. The
technology was first conceived in the 1960s and 1970s during
research into minimizing interference among channels near
each other in frequency.
In some respects, OFDM is similar to conventional frequencydivision multiplexing (FDM). The difference lies in the way in
which the signals are modulated and demodulated. Priority is
given to minimizing the interference, or crosstalk, among the
channels and symbols comprising the data stream. Less
importance is placed on perfecting individual channels.
A bundle of data organized in a specific way for transmission.
The three principal elements of a packet include the header,
the text, and the trailer (error detection and correction bits).

The data unit exchanged between peer entities of the same
protocol layer. On the downward direction, it is the data unit
generated for the next lower layer. On the upward direction, it
is the data unit received from the previous lower layer. MPDU
is the data unit exchanged between peer 802.16 MAC entities.
One MPDU is formed from one or more SDUs.
A Service Flow that has been provisioned as part of the
Registration process, but has not yet been activated or
admitted. It may still require an authorization exchange with a
policy module or external policy server prior to admission.
Quadrature Amplitude Modulation (QAM) is a method of
combining two amplitude-modulated (AM) signals into a single
channel, doubling the effective bandwidth. QAM is used with
pulse amplitude modulation (PAM) in digital systems,
especially in wireless applications.
In a QAM signal, there are two carriers, each having the same
frequency but differing in phase by 90 degrees. One signal is
called the I signal, and the other is called the Q signal.
Mathematically, one of the signals can be represented by a
sine wave, and the other by a cosine wave. The two
modulated carriers are combined at the source for
transmission. At the destination, the carriers are separated,
the data is extracted from each, and then the data is combined
into the original modulating information.
- Minimum Reserved Traffic Rate (CIR)
- Maximum Latency
- Maximum Sustained Traffic Rate (PIR)
- Traffic Priority
The rt-PS is intended to support real-time service flows that
generate variable size data packets on a periodic basis, such
as moving pictures experts group (MPEG) video. The service
offers real-time, periodic, unicast request opportunities, which
meet the flow’s real-time needs and allow the Subscriber to
specify the size of the desired grant. This service requires
more request overhead than UGS, but supports variable size
grants for optimum data transport efficiency.
A measurement of the weakest signal a receiver can receive
and still correctly translate it into data.
Received signal strength indicator.
A group of network entities administered by a DHCP Server
via its configuration file that get IP addresses in the same
subnet. A scope can define common and individual properties
for all network entities getting an IP address from that subnet.
The set of security information base station and one or more
of its client subscribers share in order to support secure
communications. This shared information includes traffic
encryption keys and cipher block chaining initialization
vectors.
An identifier shared between base station and subscriber that
uniquely identifies a security association.

Definition
Service classes are identifiers for a specific set of QoS
parameter set values. The use of service classes is optional. A
service identified by a service class is identical to a service
that has the same QoS parameter set explicitly specified.
The Service Class allows operators to configure service flows
directly on the RedMAX base station. Operators provision the
Subscribers with the Service Class Name; the implementation
of the name is configured at the RedMAX base station. This
allows operators to modify the implementation of a given
service to local circumstances without changing Subscriber
provisioning.
This feature allows higher layer protocols to create a service
flow by its Service Class Name. For example, telephony
signaling may direct the subscriber to instantiate any available
Provisioned service flow of class G711.
The data unit exchanged between two adjacent protocol
layers. On the downward direction, it is the data unit received
from the previous higher layer. On the upward direction, it is
the data unit sent to the next higher layer.
Each Service Flow represents a bi-directional data flow having
separate Quality of Service settings for uplink and downlink:
Active / Admitted
A 32-bit quantity that uniquely identifies a service flow to both
the subscriber and base station.
An ASCII string that is used to reference a set of QoS settings
that (partially) define a service flow.
This describes in general the minimum quality of service the
provider is committed to provide
A network management protocol of the IETF.

A duplex scheme where uplink and downlink transmissions
occur at different times but share the same frequency.
The standard set of protocols used by the Internet for
transferring information between computers, handsets, and
other devices.

TLV
A formatting scheme that adds a tag to each transmitted
parameter containing the parameter Type (and implicitly its
encoding rules) and the length of the encoded parameter.
