AIRAVE hooks into your existing home broadband service and effectively becomes a miniature cell tower, boosting your signal in otherwise poor areas. And unlike T-Mobile's Hotspot @ Home service, Sprint's AIRAVE will work with any Sprint phone (up to three at once) and not just a specialized UMA device.
Dial *99 from your Sprint phone to see if AIRAVE is available in your neck of the woods yet. You'll also need decent line of sight for GPS (for E911) and a free Ethernet port.
But the question remains: Are you willing to spend another $15 a month to increase your own cell signal?
