"As Sprint evaluates its broadband wireless strategy, these field trials allow Sprint to consider the viability of next generation technologies," said Cameron Rejali, vice president of broadband wireless products and operations for Sprint. "Sprint is exploring non-line-of-sight solutions that combine high data speeds, portability and self-installation with an affordable, scalable deployment model. We are pleased to have successfully leveraged the existing resources of Sprint and other industry participants in order to minimize the time and expense associated with the simultaneous trial of multiple technologies."

     The trials are testing a variety of technologies under various scenarios. The Navini and IPWireless trials deploy multicell architectures testing the capacity, portability, indoor penetration, and broadband customer experience from a pocket-sized portable device. In addition to the trials described above, Sprint also is evaluating point-to-multipoint non-line-of-sight solution that offers the performance and reliability to make it attractive for applications such as PCS/cellular backhaul access as well as access for small and medium-sized businesses. This allows Sprint to evaluate solutions that utilize advanced space-time processing and MIMO (multiple input multiple output) techniques to enable very high spectral efficiency and wireline-like reliability.

      The trial with Navini Networks is now underway in Houston. Navini's technology delivers zero-install(TM), nomadic, multimegabit broadband data rates within cellular ranges. The Navini solution utilizes adaptive phased-array smart antenna technology to increase system power and minimize interference in order to maximize coverage and capacity.

     The trial with IPWireless in Montreal, Canada, which is done in collaboration with Inukshuk Internet Inc., began last month, and will leverage the existing demonstration network of Inukshuk. IPWireless' solution, which Inukshuk still continues to test, is an international standards-based technology enabling fixed, portable or completely mobile broadband services. IPWireless utilizes advanced signal processing techniques to maximize receiver sensitivity and minimize interference, in order to maintain a strong signal and high data rates over large coverage areas with dense vegetation and building obstructions.

     "In addition to these trials, we continue to closely watch other next generation technology testing taking place all over the world," said Rejali.
