Net1 and Wireless 802.11b


Why do wireless 802.11b devices not work in conjunction with the ETC Net(1) product line?


ETC's Net (1) protocol works on Layer 2 of the OSI Model and therefore based on the MAC address of a networked device. It does not use the IP address in any way.  IEEE 802.11b is based on layer 3 protocols, it relies on valid IP addresses to work correctly.  Since the Net (1) protocol uses no IP address, the wireless products cannot communicate with the Net (1) devices.

Net (1) devices include:
