1 AB-Access Product Overview
1.1 AB-Access System
The Adaptive Broadband AB-Access System is a broadband, fixed, wireless access network for
Internet, data, video, and voice applications. AB-Access can enhance or replace existing
networks, wired or wireless, or be used to develop new networks. The AB-Access System offers:
• Point-to-Multipoint (PMP) Wireless Access Network
• Point-to-Point (PTP) Wireless Access Network [AB-Access Extender]
• End-to-End Connectivity
• Spectrum Efficiency per Offered Load
• Powerful, Flexible Elements.
1.2 AB-Access Network
The AB-Access network consists of wireless 25 Mbps cells similar in topology to the cellular
networks of today. AB-Access networks are designed for rapid and easy deployment, and
constructed from a number of Base Stations deployed in a conventional cellular pattern.
Deployment can vary from a number of small island sites to complete coverage of a chosen
geographical area. AB-Access Extender allows these cell sites to be linked together with high-
speed, long range, point-to-point connections.
1.3 System Components
The AB-Access System is comprised of the following five major components:
•
Subscriber Unit (SU)
– Located at customer premises and provides either ATM or
standard IP over Ethernet connectivity.
•
Access Point (AP)
- The Access Point is the cornerstone component of the Base Station.
The AP is the interface between the Service Provider’s terrestrial network and the
wireless fabric. Each AP has the capability to provide network service at the Physical,
Data Link, and Network Layers of the OSI reference model.
•
AB-Access Extender (EX)
- The AB-Access Extender is the inter-Base Station linking
component. The EX is the interface between the Service Provider’s terrestrial network
and the wireless PMP fabric. Each EX has the capability to provide network service at
