The system supports Ethernet and SNMP network management. AirPort transceivers transmit at 2.4 gigahertz and receive at 5.7 gigahertz. Spread spectrum technology is a proven military technique that provides transmissions that are difficult to detect, intercept or jam. Windata's products offer several security mechanisms. Each transceiver has to be registered manually with the hub before the transceiver can receive or transmit data over the network.
Identification is based on a hard-wired serial number in each transceiver.
Both transmitting and receiving data on separate bands would require would-be eavesdroppers to decode on separate frequencies. The hub architecture eliminates the chance of an intruder accessing the network and acquiring radio protocol management because the transceivers cannot communicate directly with other transceivers. A centralized network management system constantly monitors the network. Signal fade, a traditional problem with radio transmissions, is reduced significantly through network monitoring, Curley notes. Multiple receivers can adjust to propagation path changes such as doors opening or closing.
