What is ANW2
• ANW2 (Adaptive Networking Wideband Waveform) is a high-
speed waveform that allows simultaneous transmission of voice
and multiple data transmissions on a single frequency from
225.0000 MHz to 1999.9950 MHz using standard Internet
Protocol
• Automatic forming network that is self healing and has relaying
capabilities of both voice and data
• Multidirectional traffic with data rates up to 5 Mbps that appear
as full-duplex
• Uses Separate COMSEC for Voice and Data
ANW2 is a wireless Mobile Ad-Hoc Network that can have up to 10 radios in its
data network. Voice only networks can exceed 10 radios. However, they are
Guest radios and cannot relay voice. The radios communicate using a 135 ms
Time Division Multiple Access (TDMA) frame or epoch that is divided into 3
sections; Control Channel, Digital Voice, and Data.
The Control Channel allows the radios to automatically “talk” to each other and
build the network. As a radio joins or exits the network, within a few seconds all
other radios are updated to the network status. When data needs to be relayed,
coordination is automatically performed via the Control Channel.
The Digital Voice portion supports 2400 bps MELP voice that is half-duplex.
The Data portion is divided among the network radios so that each radio has a
dedicated interval to transmit data. When a radio is not transmitting it is receiving
everything on the remainder of the 135 ms frame.
