The cost to back up an enterprise's entire data communications requirements, while not prohibitive, should be known beforehand to prevent "sticker shock."

A typical data speed for a wireless IP link is about 150,000 bits per second. This is about one third the speed of DSL. There are currently deployments underway to increase this speed ten fold.

You have heard it before here that the digital communicator of today will soon be "sunsetted." If your company or your central station is not looking at the use of IP as your primary means of communications, you could find yourself left behind in the not so far future.
