1 Preface
WaveNeFg 11’ 2458 is ‘A wireless access router, that can be used to link up to hundreds of remote
Ethernet LAN’s to a single central site location. WaiveNet ll’ 2458 has voice prioritization and user
selectable bandwidth reserved for Voice, which allows WaveNet 1P245X to integrate seamlessly with
your VoIP network. Along with providing tiill duplex operation. special care has been taken in the
design of this product to minimize latency, the number one concern when deploying Voll’ networks
Purpose of Document
This document contains the information and procedures necessary to plan, install. operate. test, and
maintain Wuvt'NL'l II’ 2458 systems
Intended Audience
This document is intended for personnel who install, operate, and support WaveNer 11’ 2-158
equipment. This includes network administrators. as well as those who plan and install the radio
links. Network administrators should have experience planning. installing, and operating
internetwork equipment and networks.

2,§necifications
WuwNet [P 2458. a point-to-multipoint wireless access router, offers a low-cost alternative to
ISDN. leased lines and Frame Relay for lntemet and intranet connectivity. WaveNet [P 2458 is
capable of supporting hundreds ofremote networks from a single central location. Radio link
margins exceeding [5 dB are consistently achievable for remote routers located within 20-30 km of
a central router Site.
The system is composed of central and remote routers. The entire wireless router unit is contained
within a single outdoor enclosure The remote routers are typically mounted on the reel" or side of a
building and connect into the remote site Ethernet with a standard lOBase-l’ connection. Central
site routers are typically mounted on top ct" tall buildings or hilltops. Up to ten central units can he
co-located at each central site. allowing incremental deployment of network capacity at the central
site.
Operation in the 2.4 GHZ and $8 GHL ISM frequency bands eliminates the wait for frequency
licenses, allowing rapid deployment et'networks. Adding a new remote site to an existing network
can be accomplished within hours.
The central router physically transmits to all remotes that it serves, in a point-to—multipoint manner.
The router functionality at the remote routers insures that data is only delivered to the correct remote
site Ethernet. The remote router physically transmits only to the central router, in a point-to-point
manner. The router functionality at the central router determines if the data should be routed over
its Ethernet link or to another remote router that it serves.

Theory of Operation
Radio Network
The radio network utilizes three separate communications channels: outbound, inbound, and
inbound contention.
Packets flow from the central router to the remote routers in the outbound channel. Packets destined
for all remotes share this channel. Each remote router examines each packet, and accepts those that
have the correct radio network address (RF Net ID) and are addressed to its radio interface station
address. Normally these packets will be either received locally by the remote router (for router
management functions), or forwarded to the remote router’s Ethernet network based on the packets
destination IP address and the contents of the remote router‘s Route Table. lf there is no Route
T able entry matching the packets [P network address, the packet will be discarded. Packets are
transmitted on the outbound channel based on the order that the central router receives them.

Version 0.6 DRAFT 10/22/98
Network and Site Planning
Packets flow from the remote routers to the central router in the inbound channel. Packets destined
for the central router from all remote routers share this channel. The central router acts on these
packets in the same manner that the remote routers act on packets from the outbound channel.
When one remote router addresses a packet through another remote router. the packet is first
transmitted to the central router. which in turn transmits it to the destination remote router.
When a remote router initially has one or more packets to transmit to the central, it signals its need
to transmit by placing a reservation request in the inbound contention channel. This channel is
divided into slots, which are shared by all remote routers. It is possible that more than one remote
will attempt to transmit in the same slot (a collision), and as a result either one or the other remote
will succeed in transmitting its request, or else neither will succeed. If the remote does not receive
an acknowledgment that it can transmit its packet(s). it will retry the reservation request The
number of slots available is sull'tcient to ensure that no remote router will be consistently blocked
from making reservation requests due to collisions.
When the central router receives a reservation request from a remote router. it adds the remote
router to its polling list. The central murcr polls each remote router on its polling list in a round-
rohin manner. When a remote router receives 317011 request from the central router in the outbound
channel. it responds by transmitting one data packet in the inbound channel,
Sccu rity
Sceur'ty provisions exist at several levels. allowing a highly secure network to be deployed.
Specific security features include:
0 Frequency hopping spread spectrum protects reception of raw radio transmission
0 Proprietary physical layer protocol protects the decoding, of data from raw radio
transmission
0 Authentication feature (when enabled) prevents unauthorized remote units from accessing
radio network
0 Static route tables ensure that remote sites only receive packets destined for their local
networks
0 Passwords and community names restrict management operations to authorized users
Due to these features, the radio network is usually there secure than the wireline networks that link
to it (Ethernet, PPP links, etc.). To insure user application security, either all network links must be
physically and logically securcd (usually difficult). or else end—to end application-level encryption
should be used.
Performance
The radio link operates at a raw rate of 850 kbps full-duplex. inbound and outbound channels each
operate at a raw data rate of 850 kbps, approximately 7.0% of which goes to the contention channel
and other overhead. IP packets are transmitted in variable length segments resulting in a maximum
capacity for the combined inbound and outbound climuiels ofovcr 100 IP packets per second of size
1500 bytes.

Management
There are three basic management facilities included with each router:
0 ll'l"! l’/HTML server providing embedded management Web pages
0 SNMP MlB»ll und WuwNei II’ 2458 enterprise MlB support
0 FTP upload and download of configuration data files and system software
Configuration and monitoring of individual routers can be accomplished using the Web pages
served from within the router itself. Overall network monitoring can be accomplished using an
SNMP network management station (NMS), using both the standard MlB—ll variables as well as
device-specific variables included in the supplied WaveNet 1P 2458 enterprise MIBi The router
contains a flash file system. and configuratiun data and system software are slnred in various files
that can be accessed using FTP, No special management applications are required to use these
l'acnlilies.
Network administrators can enable or disable access to these facilities, and can limit access by use
ofpasswords or SNMP community names.
