9. What is XOHM?
XOHM is next generation mobile broadband. It lets you connect in more places, more often, anywhere XOHM has coverage. You don’t have to find a hotspot – the hotspot comes with you.
XOHM is powered by WiMAX (Worldwide Interoperability for Microwave Access), a new wireless internet technology designed to be fast and mobile.
The Best of Both Worlds
The XOHM WiMAX network combines the best of broadband and cellular technologies: the broadband speeds you experience at home with the mobility of cellular anywhere in the XOHM coverage area.
It’s like the cell phone version of a basic DSL or basic cable modem connection, except it’s wireless and always available.

21. Clearwire’s Spectrum Advantage
Average nationwide spectrum position of >120 MHz2
In the majority of the top 125 US markets, the new Clearwire will have access to more than 120 MHz of 2.5 spectrum
While there are still a number of FCC initiatives underway that impact 2.5 licensing in the US, the majority of the US already has some licensed 2.5 spectrum
The beauty of 2.5 is that it is available to support WiMAX services across North America – the US, Canada, and Mexico as well as the majority of South America, Russia, China, and portions of Africa and the Middle east
The global opportunities of this technology not only increase the international portability of the technology but decrease its long term deployment costs.

22. Sprint & Clearwire Update

23. Q&A john.muscarella@sprint.com How big is your social scene?
Imagine a Hot Spot the size of a city.
This is an ad approach we like because consumers get the “hot spot” concept.
