scope:

The present document provides the User Requirement Specifications for the TETRA Local Mode Broadband.

To improve TETRA on-site communication capabilities, the LMB aims at allowing the intervention teams to dynamically deploy an ad-hoc wireless network within the incident area, supporting voice, video and data communication (e.g. sensor-based data such as oxygen, gas, temperature). The ad-hoc wireless network should be made robust and redundant, securely supporting intervention teams of different disciplines within the same incident area. This ad-hoc wireless network should be capable of being securely connected, extended and integrated into the into a larger outdoor TETRA network.

NOTE: Further study may be required before a standardization effort is initiated.
