The 900MHz ISM radios, with their digital communicatinos and spread spectrum technology will act similar to cell phones. Cell phones with their far less than a watt of power and the virtual disappearence of outboard antennas communicate very well with excellent bandwidth to the towers they are associated with, across distances of miles. Of course these antennas are placed high enough to cover their geological areas, the idea is if cell phones could communicate directly with each other, in a sort of ad-hoc network, they would work great for this as do the Motorola and Trisquare ISM radios. The technology is sound and they all work so great by a combination of things, the nature of 900MHz, digital packets, error checking, frequency hopping spread spectrum, etc; all of these things lead to very efficient communications that become reliable in RF-dirty environments.
