Clear-Com vs. Walkie Talkies

When I was a high school teacher, we had no clear com system, and FRS radios were all I could afford with my tiny budget. They worked okay until a little kid down the street discovered us. We would change frequencies and he would find us and randomly talk over us. I had a kid on my crew who although he was great with me, was clinically diagnosed as having anger management issues. When the kid down the street would drive us nuts I would say, "I'm turning off my headset for 5 minutes, Johnny see if you can do something about this." The kid would amazingly go away. Other kids on the crew would have theses horrified looks on their faces in the aftermath of what Johnny said. Sometimes it can be very useful not knowing what happened. :angel:
 
At a couple of our schools, we went a different direction: Cordless DECT 6.0 phones. The new DECT 6.0 and 6.0+ cordless phones are digital wireless communication, and operate in a wireless band completely separate from wireless mics and from WiFi (1600 MHz).

You can get a Panasonic base with two additional handsets and get 3-way simultaneous communication. They are rechargeable with >8 hours continuous talk time.

At our middle school, we use a 3-handset system, and at the high school we use 6 handsets (takes two bases, connected by a phone cord). Make sure you get the handsets with the headset jack on the side. Full duplex communication with no interference, and >100 m of distance.
