It is sad to see, but now my XOHM hardware is in the trash. On October 5, 2008 mp3Car.com reported that XOHM service was online a week before the launch party. We also did a mobile drive test and used in other cities before their networks were officially active. Those blog posts were syndicated in news stories around the country. Our test equipment sat on the shelf until today when I decided I was fed up with terrible service from Comcast and Verizon. Out came the Xohm equipment again - but guess what? After a year and a few days, Xohm wimax has turned off ALL new accounts. What does this mean?

• 4 days ago they froze activation of new accounts on the xohm network to pave the way for a transition to Clearwire technology
• There is no hope to get your Xohm hardware activated
• We tried to reactive hardware on two old accounts
• We tried to active two pieces of hardware on one currently active account
• We tried to active online through the website and the Xohm network
• Phone reps refuse to activate devices
• Managers refuse to activate devices
• Phone reps suggested returning the device to the vendor if you can.
• Current customers with subscriptions active as of 4 days ago will get free upgrades to clear wire equipment at the beginning of the year.
• Current customers with inactive hardware appear to be screwed.

The return to your vendor advice is great advice except refunds are only available on the hardware if it was bought within the last 7 days. Furthermore, "Xohm equipment might be compatible with the new Clearwire network but probably not."We are waiting to get comments back from Xohm or Clearwire representatives. This certainly isn't a great way to treat early adopters or to build out confidence in a new network or new technology. Do you know more about this? We would love to hear from you in our mobile wimax forums.Previous posts on this topic include: In car / Computer based vehicle test in Baltimore, Vehicle testing Xohm in Boston Suburbs 10-9-2008, Bench Testing Xohm in Boston 10-10-2008
