WirelessGRID Bench Test Results. - The graphs below show AIRAYA's bench test TCP/IP throughput data for WirelessGRID bridges in each mode of operation. Each operating mode reflects a different combination of channel width, modulation, and receiver sensitivity. Actual throughput of deployed systems may be lower due to distance, radio output power limitations, and environmental variables. AIRAYA WirelessGRID bridges offer maximum system flexibility by allowing 4 channel sizes (5, 10, 20, 40 MHz wide), each capable of operating in 4 different modulations (64QAM, 16QAM, QPSK, and BPSK) and at different receiver sensitivity levels. If you have questions regarding estimated TCP/IP throughput for a particular installation, please contact AIRAYA for further consultation.
