Dave et all,this is the breakthrough I have been looking for in wireless technology. A sectorized,cross-polarization two way MMDS downstream,MDS upstream. Tuesday April 13, 9:02 am Eastern Time Company Press Release SOURCE: Wavepath California Amplifier Equipment Selected for First Two Way MDS Deployment Wavepath Implements Breakthrough Sectorized Architecture CAMARILLO, Calif., April 13 /PRNewswire/ -- California Amplifier Inc., (Nasdaq: CAMP - news) a leading supplier of RF subscriber equipment to the wireless broadband industry, and Wavepath, the San Francisco Bay area's premiere provider of wireless local loop services, announced the first deployment and use of a 20 degree sectorized antenna in a commercially operating two way wireless broadband system using MMDS and MDS frequencies. Wavepath's two way sectorization plan was fully implemented this month, using California Amplifier supplied RF and antenna equipment. The network utilizes the MMDS (2.5 to 2.686 GHz) frequency band to transmit signals to subscribers and MDS (2.15 to 2.162 GHz) frequency band to transmit signals on the return path. Through this network, Wavepath provides the most widely available high speed Internet access solution in the Bay area. The company's flagship service, iSpeed, is marketed in the Bay area through leading Internet Service Providers (ISPs), including Bay Junction Technology, Concentric Network, DNAI, ISP Networks, LaunchNet, LanMinds, MasterLink, Reality Networks, SlipNet and Urjet. California Amplifier's state-of-the-art Yagi-Horn antenna was developed specifically for two way delivery deployments. With exceptional sidelobe and cross polarization performance, the product is suitable for use as a customer premises antenna for commercial buildings or as a hub receive antenna in a sectorized system. When used as a sectorized hub antenna, the product allows the reuse of upstream frequencies in alternating sectors. ''We are very pleased that Wavepath selected California Amplifier to support the deployment of the first commercial wireless Internet service using the MDS band for upstream data,'' said Kris Kelkar, Vice President, Voice and Data Products of California Amplifier. ''As leaders in data delivery over MDS and MMDS, Wavepath is setting the precedent for the industry.'' ''Deploying sectorization in the upstream channels has not only increased the capacity of our network, but has also enhanced the robustness of our upstream links,'' stated Harry Perlow, Vice President, Engineering for Wavepath. ''The wireless revolution occurring in broadband delivery methods necessitates innovative engineering, and the equipment to implement those solutions.'' I have a follow up article also. Hiram
