  1. Airband Network Update Page 1

  2. Network • Industry standard network • Compatible with other fixed wireless networks • IP based core network, no proprietary technology • Primary equipment vendors • Cisco for data network routers and switches • BroadSoft for voice switches • Alvarion for unlicensed point-to-multipoint • Alvarion for unlicensed point-to-point in the 5 GHz band • Cielo, Dragonwave, Ceragon and Bridgewave in the licensed bands above 5 GHz Page 2

  3. Licensed and Unlicensed Spectrum • Many Airband customers require less than 9 Mbps of data connectivity • Delivered using a point-to-multipoint solution • Unlicensed spectrum • Point-to-point solution if customer’s bandwidth requirement is over 9 Mbps • Licensed spectrum above 20 Mbps • Licensed or unlicensed spectrum between 10-20 Mbps depending on several factors • Licensed spectrum used for backhaul • Co-location site to base station • Ring of base stations • Airband currently has > 250 FCC licenses • Typical FCC license is $3K for 10 years Page 3

  4. Network Breadth … 17 Airband Markets Current Markets: Austin, Baltimore/Northern Virginia, Dallas, Ft Worth, Houston, Los Angeles, Orange County, Philadelphia, Phoenix, San Antonio, San Diego, Atlanta, Miami, Ft. Lauderdale, Las Vegas, Des Moines Page 4 Confidential and Proprietary

  5. Network Updates • Integration • Network connectivity to SP Markets complete (insert backbone slide) • NOC integration complete • Task in progress: • Site consolidation in Phx • Migration to one ASN • Voice QOS in Vegas • Migrated Legacy SparkPlug VoIP Customers • Moved 85 VoIP customers from CommPartners to Airband BroadSoft switch • Migrated 1600 DID’s. 900 trunks & hosted seats • New Collocation Sites • Moved from Switch and Data to Telx in Atlanta, Miami, and Dallas • System Tools • Engineering Portal updated with All core Airband devices • In process of adding all customer sites Page 5

  6. Network Upgrades • 2009 • UPS / lightening protection at top 30 base stations • Base station router upgrades • 2010 plan • UPS / lightening protection at remaining base stations • Redundant paths for single-threaded base stations • Upgrade core routers • Upgrade base station switches • Replace non-supported equipment • Stock spares and test equipment in key markets • Results • Number of outages improving • Number of trouble tickets improving • MTTR improving • Focus on closing tickets within 1 hour, 4 hours and 8 hours • Better customer experience Page 6

  7. Engineering 2011 Initiatives • Wireless Redundancy • Continue to eliminate base stations that have single point of failure • Prioritized by highest revenue producing sites (in process of ranking the SP sites) • Replace Legacy Gear • P2P: Replace old Stratex and unlicensed equipment with licensed links • Multipoint: Replace remaining Axxcelera Gear and as much Canopy as possible for business broadband customers • Upgrades (new revenue) will also drive equipment upgrades • Base Station Upgrades • Eliminate all legacy 2924 switches from the network • Continue to upgrade UPS and lightning protection at base sites based on revenue priority • Upgrade all routers to minimum NPE-400 engine (several G1 upgrades) • Consolidate Phoenix co-location facilities • Consolidate Phoenix base station network to improve performance and footprint Page 7

  8. 2011 Major Core Router Upgrades • Upgrades to core routers in Dallas, Phoenix, and Baltimore • Replacing our 12000 Series GSR with new 7609 / 7613 fully redundant Cisco routers • Completed 1st site in Dallas (3 additional upgrades in Q1 2011) • More robust feature set for new products • Provides both layer 2 & 3 capability • IPv6 Dynamic Routing • 720Gbps forwarding rate (only 4Gbps in GSR) • 400Mpps IPv4 and 200Mpps IPv6 Page 8

  9. Network Breadth … • Routes sensitive voice packets to/from the BroadSoft voice switches in Dallas • Private line product offering • Network management Page 9

  10. VoIP Network • The Airband voice network is an overlay onto the core network and utilizes two VoIP switches (BroadSoft and Genband) located in Dallas, TX • Voice traffic from the customer location travels to an Airband base station and to a colocation site in the applicable market over wireless connections (or wired if applicable) • Sensitive voice packets travel from/to the colocation site in each market to/from the Dallas-based BroadSoft voice switches over Airband’s national MPLS backbone • Voice packets preserve their Quality of Service (QoS) packet prioritization at all times on the Airband network • Genband M6 switch architecture – “Skinny” Cisco architecture; basic phone features; low bandwidth • BroadSoft switch architecture –SIP protocol; more features; requires more bandwidth Page 10

  13. Airband Engineering Portal • Provides detailed performance monitoring of entire Airband network • Monitors all core elements • Monitors all CPE elements • Provides Sales and Sales Engineering a tool to view bandwidth utilization of any AP in network • Produces bandwidth utilization reports • CAM group uses this information to up sell customers • Reports can be directly emailed to customer • Unified reporting tool • Talks to BOSS • Talks to Trouble ticketing system • Talks to SalesForce.com
