IP400 Project
The IP400 project is a new development to bring a high speed packet system to the 400MHz band.
There are three aspects to this project:
- Transceiver development. This aspect of the project involves the development of a 400MHz transceiver for high speed data. There are two planned, the first can achieve speeds up to 600Kb/s and is based on a single chip modem. The second is a more complex higher speed modem using OFDM modulation techniques, which will follow.
- User interface development. This aspect encompasses developing a human interface to view the network and a machine interface for sending IP packets to remote applications. A preliminary specification is in development.
- Application deployment. This aspect involves deploying an IP400 network at repeater sites and connecting services for digital linking using the popular protocols such as D-Star, YSF, P25 and M17.
