Alvarion BreezeNET B Family product is designed specifically for challenging NLOS environments and adverse weather conditions, providing an efficient, cost effective, highly secured high-speed point-to-point bridging solution for backhauling and building-to-building connectivity. Operating in the 5.8 GHz band, the Alvarion BreezeNET B can bridge distances of up to 30miles (50km). The B28 delivers net 22 Mbps simultaneous throughput in each direction. This makes it an ideal solution for connecting remote local offices and headquarters, isolated buildings on campuses and in industrial zones. Providing an indoor-outdoor architecture wireless infrastructure for optimal range and capacity, Alvarion BreezeNET B28 leverages robust outdoor technologies and Orthogonal Frequency Division Multiplexing (OFDM) modulation in the same product. With features such as Forward Error Correction (FEC) coding, used to combat multi-path and noisy environments, the product operates seamlessly and efficiently in Non-Line-Of-Sight (NLOS) environments.
