The RS3100 is a portable same-frequency repeater for temporary deployments: emergency command, event support, construction sites and anywhere a network is needed for days rather than years. This article covers how to deploy it and, just as importantly, where it is the wrong choice.
Core specifications
- Same-frequency operation — transmit and receive on one channel. No frequency coordination between the repeater and terminals, which removes the single most common delay in deploying a temporary network.
- Off-network passthrough — if the repeater loses power or the backhaul fails, terminals in range continue to communicate directly with each other. The repeater becomes a liability rather than a single point of failure.
- 90ms forwarding latency — short enough for natural voice conversation with no noticeable lag.
- Terminal compatibility — works with mainstream DMR terminals, protecting existing customer equipment investments.
Typical deployment
A 1-10 square kilometre temporary coverage area can be established in 1-3 days. Equipment is set up and connected on arrival, and struck down when the event or operation ends. For comparison, our RS3500 digital repeater series is intended for permanent installations in mines, tunnels and large buildings where continuous unattended operation matters more than portability.
Where the RS3100 is the wrong tool
Being explicit about limits is more useful than a broader claim:
- Not for permanent sites — the portable form factor and power design are optimised for temporary use, not for unattended multi-year operation
- Not for capacity-limited events — same-frequency operation shares one channel; high-density scenarios with many simultaneous transmissions need a different-frequency or trunked design
- Coverage is site-dependent — the 1-10 km2 figure assumes reasonable antenna height and line of sight; concrete and steel structures change the result, and any serious deployment needs a site survey
How to specify the right configuration
Tell us three things: the area and terrain, the number of simultaneous users, and whether the deployment is temporary or permanent. That determines whether you need one RS3100, several linked units, or a different architecture entirely. We will say so if the RS3100 is not the right answer — the scenario pages set out which architecture suits which situation.
