Mesh technology boosts wireless performance

摘要

As THE POPULARITY OF wireless networking grows, users are demanding higher bandwidth, greater coverage, and improved reliability. The standard point-to-point or point-to-multipoint technologies, such as 802.11 and Bluetooth, are short range, line-of-sight, wireless networks with some inherent limitations. The bandwidth of these networks decreases as additional nodes join the network and share the access-point data stream. Bandwidth also suffers as the range increases, due to link noise and transmission errors. Most standard wireless networks have "dead spots" within their effective range that exhibit low signal quality due to intervening objects or low signal strength.
