Freewave Serial Wireless Ethernet Bridges offer a unique wireless solution that combines the connectivity features of Ethernet with long distance spread spectrum SCADA radios. Unlike competing 802.11 wireless Ethernet solutions, the Freewave radios operate at 900MHz, reaching much further and penetrating obstacles better. The Wireless Ethernet Bridges use the same SCADA radio technology as their field-proven, time-tested serial data counterparts, with the same extremely wide operating temperature range and high noise immunity, ideal for harsh environments.
Freewave Serial Wireless Data Tranceivers provide a error-free transparent link between two or more points regardless of the message protocol; "like a wire through the sky". This includes timing sensitive protocols such as Modbus.
Freewave Serial Wireless Ethernet Bridges operate up to the maximum legal output power, combines with a superior front-end design that "digs-out" weak received signals. Built-in 32-bit error detection and correction ensures high throughput even in noisy environments.
Using a laptop or desktop PC, Freewave's support software provides real-time
access to operating status information anywhere in the world.
