700 MHz vs. 2. 5 GHz Interference occurs between these cochannel cells Lower reuse 1. 2. 3. 4. 5. 6. Interference increases as distance between co-channel cells decreases Higher reuse Sprint’s 2. 5 GHz licenses allow for higher throughput and capacity Two to three times as many sites required for initial coverage at 2. 5 GHz compared to 700 MHz 10 to 15 sites required at 700 MHz for the same capacity as one Sprint site at 2. 5 GHz FDD at 700 MHz is not finalized in any standard and product availability is unlikely before 2010 Low cost Wi. MAX 2. 5 GHz chipsets expected in 2008 International roaming expected at 2. 5 GHz; 700 MHz roaming uncertain 6 Xohm Overview

Embedded Model: Changing the Subsidy Paradigm Traditional Wireless • The device is the customer • The carrier subsidizes the device and manages the supply chain • Contracts and cancellation penalties are required to recoup the subsidy 7 Xohm Overview Mobile Internet • Embedded mobile broadband • Device optimized on a particular use • Customer buys the devices from their retail store at nonsubsidized retail prices • Freedom to purchase a subscription, ad hoc usage, or a particular service
