Shipboard V-Band Wireless Network Navy SBIR FY2005.1 Sol No.: Navy SBIR FY2005.1 Topic No.: N05-042 Topic Title: Shipboard V-Band Wireless Network Proposal No.: N051-042-0531 Firm: MaXentric Technologies LLC 2071 Lemoine Avenue Suite 302 Fort Lee, New Jersey 07024 Contact: Houman Ghajari Phone: (201) 242-9800 Web Site: www.maxentric.com Abstract: MaXentric is offering a cost effective and an innovative solution for a V-band based WLAN (V-WLAN). Our V-WLAN solution was conceived in order to overcome the challenges of V-band WLAN development and deployment while preserving the technological legacies created by the existing WLAN systems. Our V-WLAN solution solves the LOS requirements at V-band frequencies by deploying a smart coaxial distribution system. Using spatial transmit and receiver diversity techniques, Our V-WLAN solution virtually eliminates any non-LOS issues associated with RF propagation at 60 GHz. Our V-WLAN solution offers an innovative architecture to distribute signals using a single coaxial cable for signal and power distribution with a built in fail-safe mode to bypass any antenna node failures. To preserve the unbeatable economies of scale and excellent technological legacies created by the existing WLAN standards (802.11 WLAN or 802.15 WPAN), our V-WLAN solution would use the existing 802.11 or 802.15 MAC and Physical Layers. In this way, our V-WLAN solution would maximize the use of Commercially Off The Shelf (COTS) 802.11 base-band chip sets. Benefits: V-Band offers several GHz of unlicensed bandwidth in the 60 GHz region. The availability of this vast yet free spectrum block makes V-band the favorable candidate for the third generation WLAN systems. The main characteristic of RF propagation that made V-band frequencies unattractive (namely excessive propagation loss due to Oxygen absorption) is making it attractive again for commercial and DoD applications. In the commercial WLAN market, high propagation losses translate into excellent signal containment and therefore the potential for high spectral reuse, a highly desired combination for a bandwidth hungry frequency starved WLAN industry. For the DoD application outlined in this topic, V-band high atmospheric attenuation of signals translates to high electromagnetic concealment for Navy vessels that use WLANs onboard. With the rebirth and renaissance of millimeter wave technologies currently underway, and applications enabled by a new generation of V-band silicon chips, V-band based WLANs have the potential to soon rival many existing WLAN technologies.
