WiN7000 cBST Product Description | 15

2.1 Introduction

The WiN7000 base station is an IEEE 802.16-2005 compliant wireless device designed for the

deployment of point-to-multipoint (PMP) network architectures.

The WiN7000 base station is an outdoor device. Each Win-Max

network segment is

comprised of a WiN7000 base station and one or more WiMAX Forum 802.16e Wave 2

Certified subscribers. Each subscriber registers and establishes a bi-directional data link with

the sector controller of the base station.

WiN7000 base station is part of the 802.16e Access Service Networ (ASN). It functions as a

central hub or concentrator, connected to a Core Services Network (CSN) through the Access

Service Network Gateway (ASN-GW), managing wireless links for fixed, nomadic and

mobile subscribers. The WiN7000 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 802.16e Mobile WiMAX Compliance

The IEEE 802.16-2005 specifications describe a PMP broadband wireless access standard for

systems. This standard includes descriptions for both the Media Access Control (MAC) and

the physical (PHY) layers.

The WiN7000 base station is compliant to IEEE 802.16-2005 WiMAX forum Wave 2 profile.

Note

802.16e standards are subject to amendment, and Win-Max

product family design

compliance applies to a specific revision of the standard. The Win-Max

product family

does not support mesh communication (direct subscriber-to-subscriber).

WiNetworks is an active member of the WiMAX Forum™ and participates in interoperability

testing in the WiMAX Forum.

2.3 Block Diagram

WiN7000 consists of the followings modules:

1. Base-Band Board – including the WiMAX 16e Base-Band SoC plus the network interface

(Gb-ETH Switch) plus the analog front-end that interface to the RF module.

2. Timing Module – Clock source for the BST modules. Can be either GPS receiver or

IEEE1588 (IP packet sync).

3. CPU Module – High performance CPU with its memories, that runs the WiMAX 16e

MAC plus the Layer 3 - Networking stacks that runs above the WiMAX MAC. The CPU

is responsible for the management (control, configuration and maintenance) of all the BS

modules.
