While looking for some Clearwire Q3 Earnings material, this graphic nicely popped up. It's clear that Clearwire is punctuating its vast national spectrum versus the tier one carriers.
- Operator A is Verizon Wireless
- Operator B is AT&T
- Operator C is T-Mobile
- Operator D is Sprint
Looking ahead for roaming:
- AWS LTE stands to be a major roaming frequency with Verizon Wireless and T-Mobile in control.
- PCS LTE roaming should eventually happen. Sprint is the early adopter out of the gate.
- Cellular 800/850 LTE - big question mark on what will be when AT&T and Verizon Wireless refarms.
