makes you wonder why no manufacturer has stepped up to the plate.

i see nothing in the part 15 rules barring this type of operation on 900 mhz 2.4ghz or 5.8 ghz could be used as a repeater linking backbone for extended range and repeater synchronizing/simulcasting as well.

there could also be encryption and other advanced capabilities.

with everyone now vacating 900 mhz in favor of 1.9, 2.4, 5.8 ghz bands 900 is being under utilized in most area's.

something like this would be a big seller. especially to theme parks, campgrounds, parks departments, construction, etc.

stuff would eventually start to trickle down to us hobbyist users and would be a real nice advanced license free PRS.

portables could be 1 watt with a dipole antenna, mobiles can be 1 watt with a 5db mobile antenna.

repeaters and bases can have advanced features like repeater linking via 2.4 ghz and diversity receive transmit sector antenna's, base can have small yagi's or 4 bay dipoles.

Do you know about the C block spectrum that pretty much opens today?

A lot of wireless devices will come out do to it.
