Router Enables High Reliability Wireless Mesh Operation

Fri, 07/23/2010 - 10:02am
Deeter Electronics announces the introduction of a wireless router to increase the range and reliability of their recently launched Deeter Wireless Sensor System for industrial measurement and control.

The new Wireless Router may be added to a Deeter Wireless Sensor System to significantly increase the range of the wireless communication between sensors and a base station. Deeter Wireless Routers may also be used to improve communications reliability.

A basic Deeter Wireless Sensor System is comprised of a base station and a remote sensor node, either a general purpose Deeter Sender or self contained Liquid Vertical Continuous Sensor (LVCS-RF) probe. In many industrial environments the signal will be attenuated by obstructions and fading may result from multiple signal paths caused by reflections. These effects reduce the quality of the communications link and the achievable range. Adding a Deeter Wireless Router to the system extends the effective range and improves signal quality.

In use, the Wireless Router should be positioned midway between the remote probe or sender and Base Station, possibly offset in order to avoid obstructions that might cause interference. Up to four Routers may be used in a single system with data being retransmitted a number of times before reaching the Base Station. This will greatly extend the transmission range and reliability.

The use of multiple Routers allows the wireless network to automatically establish the most effective signal route between probe and Base Station at turn-on. Should this signal path become interrupted for any reason the Router network will re-establish the most efficient and reliable signal path. In this mode the Routers are operating as a self-healing wireless mesh network offering maximum signal reliability.

The Deeter Wireless Sensor system uses the internationally recognized IEEE 802.15.4 protocol in the 2.4 GHz ISM radio band allowing users to install approved devices with no licensing requirements. It operates on one of 16 radio frequency channels available allowing several wireless sensor networks to share the same wireless spectrum without interference.
