    Sample Technology Licensing

    • Wireless (Wi-Fi) Hot Spot Network Access: Package includes five technologies: Global Authentication; Network Admission; Traffic Gateway; Client Module and Policy Manager.
    • Wi-Fi Location Determination: Technology to locate a wireless client by pattern matching the measured signal strength from multiple wireless access points against a database of previously collected signal strength.
    • Cellphone Power Management: Technology that leverages the cellular radio to wake-up the Wi-Fi radio on SmartPhones, Laptops, and NetBooks.
    • Virtual WiFi: Technology that abstracts a single Wireless LAN card to appear as multiple virtual Wireless LAN cards to the user/OS.
    • Mesh Connectivity: Ad-hoc routing and link quality measurement for mesh networks as a loadable software driver.
    • Undelivered or Delayed e-mail Notification System: An alerting technology for users when e-mails sent to them have been delayed or lost.
    • High Performance Internet Connectivity in Moving Vehicles A set of protocols, algorithms, and mechanisms that enable moving clients to transmit data packets on the wireless link that offers the fastest delivery, which minimizes application traffic delays.
    • Fast Wi-Fi Hand-off to Diversified Base Stations: Technology that opportunistically exploits base station diversity to minimize connection disruptions while supporting interactive applications for moving Wi-FI enabled clients.
    • Smart Antenna: Low cost directional antenna technology designed for increasing the range, throughput, and consistency of 802.11 networks.
