Cable AML has delivered a BWA 2002 integrated broadband wireless access system. The BWA-2002 System is a full-duplex, two-way, fixed-wireless communication system operating in the MMDS / MDS frequency bands (2.500 to 2.686 GHz for downstream and 2.150 to 2.162 GHz for upstream).

The system is designed to co-exist with an existing multi-channel analog TV distribution service. Future upgrades under consideration include additional channels of two-way data and a digital upgrade of the multi-channel video system.

The main application of the system is for high-speed Internet access, although other IP-centric services such as LAN (Local Area Network) extension, VPNs (Virtual Private Networks) and VoIP (Voice over IP) can also be implemented depending on market conditions.

The BWA-2002 system utilizes the 2500 to 2686 MHz MMDS band for downstream transmission. The band is divided into thirty-one channels, each 6 MHz wide. Each downstream data channel has a throughput of 30 Mbps (using 64 QAM modulation format). The upstream channels are in the 2150 to 2162 MHz band. Upstream channels of 0.2 MHz to 3.2 MHz bandwidth can be implemented. Upstream data throughput is up to 5.12 Mbps with QPSK modulation or 10.24 Mbps with 16QAM-modulation.

As with any system developed by Cable AML, this BWA equipment was integrated at our Torrance facility and tested as a system.

When the testing was completed, the customer’s engineering staff attended a comprehensive training program on system deployment, operation, and maintenance at the Cable AML factory in Torrance. The training was conducted under near operational conditions using the customer’s own equipment. This approach to training serves to make field deployment and operation more effective.
