Chapter

2 Overview

Congratulations on your purchase of the Redline Communications RedMAX 4C wireless

broadband base station. Redline Communications is a world leader in design and

production of Broadband Wireless (BFW) systems. The RedMAX 4C base station is a

complete Mobile WiMAX (IEEE 802.16e-2005) compliant broadband wireless base

station. Fully designed as a WiMAX-based solution, the base station has demonstrated

interoperability with an emerging base of WiMAX subscriber equipment.

Services

The base station is (part of) the IEEE 802.16e-2005 definition of a base station. A base

station functions as a central hub or concentrator, connected to a WAN network access

point, and managing wireless links for remote subscribers. The base station enforces the

Quality of Service (QoS) settings over the air interface by controlling all uplink and

downlink traffic scheduling -- providing non-contention based traffic with predictable

transmission characteristics.

The base station delivers fixed, nomadic, portable, and mobile services. Portable

services provide limited handover for users moving within and across neighboring

sectors and base stations. Mobile services provide full roaming capability to maintain all

QoS (quality of service) and SLAs (service level agreements) while moving at vehicular

speeds through WiMAX coverage areas.

Equipment

The base station consists of an indoor chassis and outdoor transceiver and antenna.

Each operational wireless broadband network segment is comprised of a base station

and one or more WiMAX Forum Certified™ subscribers. Each subscriber registers and

establishes a bi-directional data link with the base station.

The base station operates under the control of an ASN gateway providing supporting

management functions including: Accounting, Inter-Base Station Mobility, Base Station

Management, Admission Control, and Access Authentication.

Network

High reliability is provided through comprehensive OAM&P (Operation, Administration,

Maintenance and Provisioning) features including: fault tolerance, alarms and TCAs

(Threshold Crossing Alerts), performance and inventory reports, and software

management. Chassis management can be performed (via the SOAP/XML interfaces)

using the Redline Management Suite (RMS) or a third party Element Management

System (EMS). The RMS uses the TMF 814 NBI (Northbound Interface) to the OSS

(Operations Support System) and SNMP MIBs.

2.3 Feature Details

2.3.1 IEEE 802.16e / WiMAX Compliance

The RedMAX 4C base station supports the following Certification Wave II Mobile WiMAX

System Profile:

- WiMAX Certification Wave 2: Profile 3A: 2.5-2.7 GHz, 5/10 MHz, TDD

2.3.2 High Availability Features

The modular design of the base station chassis provides the following High Availability

(HA) features:

- Hot-swap capability for field replaceable modules

- Parallel paths with no single point of failure

- In-service software upgrade

- Fault Management: monitoring, detection, and reporting

- Checkpoint service

2.3.3 PHY Specification

The base station is designed for 2-11 GHz operation based on the WirelessMAN-

OFDMA PHY definition in the IEEE 802.16e-2005 specifications. Refer to the system

specifications for supported frequency ranges.

2.3.4 OFDMA

Orthogonal Frequency Division Multiple Access (OFDMA) is a multi-user version of the

OFDM digital modulation scheme. Multiple access is achieved in OFDMA by assigning

subsets of subcarriers to individual users - allowing simultaneous transmission from

several users.

OFDMA uses the Fast Fourier Transform (FFT) algorithm to implement modulation and

demodulation functions. Using adequate channel coding and bit-interleaving, OFDMA

can perform very well in severe multipath environments, mitigate frequency selective

fading and provide high spectral efficiency.

2.3.5 Privacy

The base station implements IEEE 802.16e-2005 Privacy Sublayer and the NWG

Standalone Model Security Architecture. The base station provides an Authentication

Relay function to manage exchanges with an Authenticator in the ASN (Authentication

Relay Protocol-EAP), and a Supplicant function in the CPE (PKMv2-EAP). This

standards-based framework provides user/device authentication and services

authorization using off-the-shelf AAA servers.

2.3.6 Time Division Duplexing (TDD)

The base station system uses time division duplexing (TDD) to transmit and receive on

the same RF channel, or separate RF channels using HD-FDD (half-duplex 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.

User

BASE STATION

Manual

2.3.7 CTC (Convolutional Turbo Codes) and Coding Rates

Turbo codes are used for error correction. When used in combination with parity-check

codes, these techniques can approach the theoretical limit (Shannon limit) of maximum

information transfer rate over a noisy channel.

As part of the error correction technique, 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, 3/4, and 5/6.

2.3.8 Modulation

The modulation technique specifies how the data is coded within the OFDMA carriers.

The base station supports BPSK, QPSK, 16 QAM (Quadrature Amplitude Modulation),

and 64 QAM modulation.

2.3.9 Channelization

The base station is a frequency-specific system, with the frequency band defined by the

transceiver unit. 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.

2.3.10 Service Flows

A Service Flow represents a unidirectional data flow with separate QoS settings for

uplink and downlink. Service flows provide the ability to set up multiple connections to

each subscriber in a sector. Separate service flows can be established for uplink and

downlink traffic, where each service flow is assigned a unique service level category and

separate QoS settings. This feature allows segregation of high-speed/high-priority traffic

from less time-critical flows.

Table 1: Overview - Base Station Service Class Types

3.3 PWM - Power Module (Chassis)

The PWM power module provides regulated DC power for all modules in the base

station chassis.

3.3.1 Module Description

The PWM features redundant inputs, allowing power to be supplied from two

independent DC sources. A second PWM module may be installed to provide

redundancy. When two PWM modules are installed and operating normally, the failure of

one PWM module will not affect operation of the base station.

The PWM module is fully 'hot swappable' and the standby unit may be removed and

installed without affecting operation of the base station (refer to 'Using the Hot-Swap

Feature' in the installation guidelines).

The TCM manages the power for each uTCA module. The uTCA Power Module

incorporates a MicroTCA EMMC (Enhanced Module Management Controller) that can

operate independently or be controlled by the TCM module. The EMMC reports voltage

and current levels, faulty power conditions, and local temperature status to the TCM.

3.4 TCM - Transport, Clock & Control Module

The Transport, Clock & Control Module (TCM) is a multi-purpose card combining the

OBSAI Transport Block and Control & Clock Block functions.

3.4.1 Module Description

The transport function manages traffic aggregation and the control and clock functions

provide synchronization between the base station modules. Downstream data traffic

received from the core network is distributed to the baseband modules for transmission

over the wireless network, while upstream traffic from the wireless system is aggregated

and sent over the backhaul connection to the core network.

The base station clock is synchronized by a GPS reference signal. Clock signals are

sent through the backplane to the other base station modules.

The shelf may contain up to two TCM modules for redundancy. The TCM module is fully

'hot swappable' and the standby unit may be removed and installed without affecting

operation of the base station (refer to 'Using the Hot-Swap Feature' in the installation

guidelines).

3.5 BBM - Baseband Module

The baseband module (BBM) is a WiMAX wireless modem (IEEE 802.16e PHY and

MAC).

3.5.1 Module Description

Downstream data traffic received from the core network is distributed to the baseband

modules for transmission over the wireless network, while upstream traffic from the

wireless system is aggregated and sent over the backhaul connection to the core

network. This port has an associated MAC address.

Each BBM connects to one RRH (one sector) and supports two SISO channels or one

MIMO channel. Up to six BBM (plus two standby) modules may operate concurrently.

The BBM is frequency agnostic (frequency band determined by RRH). The base station

shelf supports an N+1 redundancy configuration. The OBSAI RP3-01 interface cabling

must be provided from each standby BBM module to a radio.

The BBM module is fully 'hot swappable' and may be removed and installed without

powering off the chassis. Removing and replacing a BBM module will not affect

operation of the base station.

3.6 RRH - Remote Radio Headend

The Remote Radio Headend (RRH) is the outdoor radio transceiver.

3.6.1 Module Description

The RRH contains an OBSAI RP3-01 interface and two identical TDD RF head-ends

(RFHEs). Each RRH supports two SISO channels or one MIMO channel. Frequency

bands and power are determined by the RRH (the BBM is frequency band agnostic).

The RRH interfaces to one baseband module (BBM) using the OBSAI RP3-01 optical

interface to exchange data and control signals. Power is supplied to each RRH through

separate cabling from dedicated power modules (not base station PWM). The RRH may

be mounted up to 300 m (984 ft) away from the base station chassis. This distance can

be extended based on the fiber type and method of supplying power to the RRH.

Each RRH module has two optical interfaces. These interfaces may be used in one of

the following configurations:

- Connect RRH to a standby BBM module. The optical interface cabling must be

provided from the standby BBM modules to the radios.

- Interconnect two RRH modules (daisy-chain) to provide 1+1 redundancy or 4-branch

MIMO (future option).

Each RRH module contains two RF head-ends. The failure of one radio within the RRH

enclosure results in graceful degradation, but not loss of service.

5.1 Synchronization

In TDD mode, the base station and the subscribers transmit at the same frequency, and

require precise base station synchronization (timing between downlink and uplink bursts)

to minimize potential interference and ensure good performance. The IEEE 802.16

standard calls for the use of global positioning system (GPS) receivers to provide the

precise time reference for synchronization of WiMAX networks.

5.2.1 No Redundancy

This deployment scenario provides maximum economy without redundancy. In this

configuration, failure of the TCM or PWM module will cause the system to be

unavailable. Failure of a BBM will result in a loss of service for the affected sector.

Failure of a sector radio will revert to SISO for the affected sector or a loss of the sector

(based on the type of failure).

5.2.2 Basic Redundancy

Basic redundancy is provided by adding standby transport, clock and control (TCM) and

power (PWM) modules. Baseband-radio link redundancy is achieved by installing a

standby BBM module with optical interface cables connecting to each sector RRH.

In this configuration, failure of a PWM or TCM module will switch to the dedicated

standby. If any single BBM fails, the system will switch to the standby BBM module. If

any single RFHE RF component fails the radio will operate in SISO mode for that sector.

The base station uses TDD (Time Division Duplexing) for system uplink transmissions,

employing a single frequency for both the base station and the subscriber. The PMP

downlink is a broadcast medium shared and received by all subscribers in the sector.

Transmission priorities are adjustable during provisioning of WiMAX subscribers.

For each channel bandwidth (3.5, 5, 7, and 10 MHz), there are six possible modulation

and coding combinations. In the following tables, the Ethernet throughput is the rate that

can be achieved after burst overhead and acquisitions times are removed.

7.11 GPS Synchronization

Important: To minimize inter-sector RF interference, synchronization must be

used to coordinate RF transmissions of base stations.

The IEEE 802.16 standard calls for the use of GPS (Global Positioning System)

receivers to provide the precise time reference for synchronization of WiMAX networks.

Operating in TDD mode, the base station and the subscribers transmit at the same

frequency, and require precise synchronization between downlink and uplink

transmissions. Proper coordination of these activities is required to minimize interference

and ensure the best overall system performance.

The base station uses the GPS 1 PPS signal to set the frequency of the TCM onboard

clock. This TCM reference clock is used when broadcasting a radio frame

synchronization signal to all BBM and RRH modules. If the 1 PPS signal becomes

unavailable at any base station, that TCM enters 'holdover mode' to maintain the highest

accuracy until the GPS signal can be restored.

GPS reference clock systems require that a receiver be placed at each base station and

that the GPS antenna have line-of-sight satellite access. Ideally, a GPS antenna should

be mounted on a rooftop with a full 360º view of the sky, but often an antenna mounted

on the side of a building or a tower with a 180º view of the sky is adequate.

The base station provides the following synchronization schemes.

Model 1 (Standard) – External GPS Unit

The GPS component is an integrated GPS receiver/antenna module. Signal input is

through an RS-232 cable connected to the Serial 1 port on the TCM front panel.

Recommended for short cable runs (~20m).
