and once again, ScamPlan 2.0 is underway. Many of the incumbent licensees are using older equipment and infrastructure that won't accept the new band plan. The 900MHz band stuff uses channel identifiers like 700/800, and most Motorola subscriber hardware has those channel tables hard coded in ROM. Think Privacy Plus radios that don't support Flashport like GTX and MTX9000s, or older MSF5000 based radios. (I know of several StartSite systems at casinos and hotels that still use this).
Oh I know, "time for them to upgrade" but unlike the public safety rebanding where Sprint had to pony up, who is gonna pay those licensees to replace/realign (if possible) their perfectly functional, paid for and adequate 900 stuff?
anyone? Bueller? Anyone? The telecom mafia always gets it's way in the end. Their mission: make every man, woman, child and animal a paying customer FOR LIFE. Grabbing every MHz of RF is their path to accomplishing this.
