The BH Module is a Point-To-Point radio that carries traffic to and from AP Clusters. A set of Point-to-Point BH Modules can also be used as a low latency Ethernet bridge between any two networks or between a network and a single remote computer. In the event no convenient fiber or cable connection is available for IP connectivity to an AP Cluster, a set of BH Modules can be used. Each BH Module communicates to another BH Module using a highly directional antenna. The BH Module operates with a raw data bit rate of 10 Mbps with an approximate throughput of 7+ Mbps and has a maximum range of approximately 35 miles.
The BH uplink/downlink bandwidth ratio for a single BH link is configurable by the operator (i.e. 75 percent downlink and 25 percent uplink or 50 percent uplink and 50 percent downlink – set at timing master). When two BH pairs are configured back-to-back in a daisy chain configuration, they each need to be configured for symmetrical load with 50 percent allocated for uplink and downlink. Each BH Module receives its 24VDC power from a 110-power supply (ACPS110-01 Configuration Guide or -02) or the 90V-230V switching power supply (ACPSSW-01) and associated RJ45 connector. The BH Module can also be connected to the CMM, which will supply power to the BH Module and networking with the AP Modules at the AP Cluster.
