CHAPTER 1—Advanced Radio Operations
8 P800 User’s Manual
• Unlike your conventional FM radio, your P800
is a node on an Internet-Protocol (IP) network with
its own unique IP address.
Addressable Headers
Messages intended for you (whether voice or data) are
broken into packets with identifying headers, just like
World Wide Web internet communications, and
targeted to your specific IP address.
• You can travel anywhere within your network
and messages intended for your IP address will
find their way across the network to your personal
receiving set.
This doesn’t mean your communications are traveling
across the World Wide Web. Far from it. OpenSky is a
private wireless Intranet that adopts the best features of
IP protocol for increased communications efficiency
and capacity.
Integrated Voice and Data
Your P800 Portable Radio is a hardware component of
the OpenSky network, an integrated voice and data
communications system that delivers end-to-end digital
voice and data transmissions over the same wireless
network to a single handheld device.
Digitized Voice, Text and Graphics
By converting analog voice waves to digital
information before transmitting them over the network,
OpenSky technology makes it possible for portable
radio users to send and receive voice transmissions at
the same time they receive and view data on the radio’s
display screen.
