Aviat Networks Future of Backhaul Showcase

Located inside its pavilion, Aviat Network will present its vision for
the future of backhaul networks, focusing on the key challenges faced by
mobile service providers around the world:

    - 4G/LTE Backhaul-A Dose of Reality. The requirements for 4G/LTE backhaul
      capacity are being overhyped, leading to operators wasting potentially
      billions of dollars by running fiber to cell sites. Understand how
      microwave exceeds the true backhaul capacity needs of 4G/LTE with high
      reliability-and much more cost effectively.
    - Simplifying Mobile Backhaul Evolution. The evolution of mobile network
      infrastructure to all-IP is potentially risky and complex, giving
      operators many confusing options. Learn how Aviat Networks is
      developing solutions that will help simplify and lower the cost of this
      evolution.
    - Small Cell Backhaul-Challenges and Opportunities. There is a growing
      consensus in the industry that operators will need to deploy a new
      "underlay" network of small, micro-base stations to provide the needed
      capacity and coverage for 4G. Find out how microwave is uniquely
      positioned to provide the backhaul for this new class of base stations.

Product Showcase

    - Aviat WTM 3000. A fully functional Carrier Ethernet transport node in a
      true zero-footprint package, the WTM 3000 for the first time includes
      advanced radio, modem and Ethernet networking functions all in a
      compact outdoor unit, unlike other "all-outdoor" packet radios that
      require an indoor unit or a separate switch/router to provide important
      networking advanced radio features.
    - Eclipse IDU GE3. An ultra-compact indoor unit (IDU) that combines the
      very latest Carrier Ethernet networking and advanced radio features for
      hybrid TDM/Ethernet or all-Ethernet/IP wireless transmission. The
      Eclipse IDU GE3 enables the deployment of cost-effective wireless tail-
      end cell-site connections and standalone point-to-point links.
    - Eclipse DAC GE3. A new plug-in interface module for the Eclipse Packet
      Node platform, the DAC GE3 provides the most advanced Carrier Ethernet
      switch subsystem available in microwave backhaul today. Featuring
      higher capacity and an impressive breadth of new capabilities, this
      third-generation design sets a new benchmark for resilient wireless
      access and aggregation networks.

Aviat Networks will also host a cocktail and tapas event on Monday,
Tuesday and Wednesday from 5:00 - 7:00 p.m. in courtyard pavilion #CY08.
Customers and other friends of the company are invited. Please contact your
representative if interested in attending.
