Bittium Tactical Wireless IP Network™

High-data-rate IP network for modern tactical communications providing outstanding data performance across the battlefield.


With the Software Defined Radio (SDR) based Bittium Tactical Wireless IP Network (TAC WIN) system battlegroups can create high-data-rate wireless IP networks as a backbone to support command and control (C2) data transmission during military operations. Flexibility to use the Bittium solution in different frequency bands and network structures provides cost effectiveness, ease of use and efficiency compared to existing tactical data link networks.

Bittium TAC WIN is a stand-alone wireless broadband military/authority network that can be deployed in any location. It enables the formation of an independent IP network and is compatible with existing infrastructure, both wire-line and wireless.

Being based on Software Defined Radio (SDR) makes the system versatile, upgradeable and easy to adapt. It enables a mesh network solution with high-data-rate and automatic network configuration required by battlegroups on the move.

Bittium TAC WIN has an excellent performance and form factor as both network node and router functionality are integrated into a single product.
