Want to pay only for what you need? Then the Rover Puck service from Clearwire ought to do the trick, as this pay-as-you-go model is now available. The Rover Puck is a device which is capable of linking a number of WiFi-enabled devices to a WiMax signal, and Clearwire is also more than willing to extend their prepaid hotspot service for other cellular providers – regardless of whether they’re outside the tent or not. The Rover Puck will see a Beceem BCSM 250 WiMAX chip in action within, which is similar to the ones found in the Sierra Wireless AirCard W801. It does look as though more and more people are no longer going to place themselves under the mercy of public Wi-Fi network availablility and move on to a portable broadband solution instead.
