4 DESCRIPTION
The VIDA Broadband Client shown in Figure 4-2 is part of M/A-COM’s VIDA Broadband network.
Clients are available in four configurations; High-Power Standard, High-Power Hardened, Low Power
Standard and Low Power Hardened. The High Power Standard model may be installed in fixed or mobile
applications. The Low Power Standard model may be installed in fixed applications. Both the High and
Low Power Standard models are designed to operate from an AC or DC input voltage and utilize an
Ethernet based data port configuration. The Hardened models may be installed in fixed applications,
operates from a DC input voltage and incorporates a 100-BaseFX fiber Optic data port configuration for
increased hardening of the unit.
The VIDA Broadband Client provides public safety grade wireless connectivity for M/A-COM’s 4.9 GHz
VIDA Broadband network. The open standard IEEE-based wireless broadband communications protocol
of 802.16 is utilized, thereby providing true Quality-of-Service (QoS) while operating on contention-free
licensed frequencies. The VIDA Broadband Client provides public safety grade end-point connectivity
for M/A-COM’s 4.9 GHz VIDA Broadband network. The 802.16 protocol delivers an over-the-air Data
throughput from 2 to 19 Mbps. All communication over the wireless channel is scheduled by the base
station, with contention slots provided for subscriber stations to request bandwidth. Up to 16
“connections” can be established between the base station and the VIDA Broadband Client, each
connection having a different QoS, allowing for greater flexibility when designing a network.
Low priority processes (such as email) can be mapped to best effort services while high priority processes
(such as streaming video or LMR backhaul) can be mapped to unsolicited grant services (UGS) which
offer guaranteed throughput. Network convergence is provided in the form of 802.16 classifier rules that
ensure network level QoS over the airlink.
