# Specification

Tactical Software-Defined Radio for complex electromagnetic environments.

<mark style="color:$success;">**TACSDR**</mark> is a <mark style="color:$success;">**TAC**</mark>**tical&#x20;**<mark style="color:$success;">**S**</mark>**oftware-**<mark style="color:$success;">**D**</mark>**efined&#x20;**<mark style="color:$success;">**R**</mark>**adio** built for the modern tactical mission. Its software-defined architecture makes it the world’s first and only handheld used for communication, signal intelligence and spatial sensing purposes.

{% hint style="success" icon="hands-clapping" %}
This specification is focused on TACSDR's communications capabilities
{% endhint %}

TACSDR delivers voice, video, and high-speed data in a compact, highly portable handheld platform. Using a Linux-processor and [AllSeeing's software-defined radio architecture](https://www.allseeingtech.ca/), it supports ad-hoc, self-forming, and adaptive networking for dismounted users on the move. Its software-driven design allows the system to be upgraded and reconfigured as mission requirements, waveforms, and communication needs evolve.
