The fast track towards 5G independence

Many areas are still not covered by 4G and 5G networks: buildings, underground car parks, factories outside cities, remote villages, etc.

Coverage of those areas can be a difficult task for telecom companies because investments are high, demand is unpredicatble and the number of users is low.

Many users are thus left with no option.

We will introduce how Rapid.Space can solve this situation in cooperation with telecom companies thanks to an all-in-one, autonomous, open source RRU and BBU with a typical cost of less than 2000€.


Rapid.Space was founded in 2020 by Nexedi, Amarisoft and a few VIPs of the IT and telecom inudustries.

Nexedi brings its open source stack, in particular its billing platform, its edge-cloud platform and its big data platform, all open source.

Amarisoft brings its purely software defined 4G/5G stack which covers all aspects needed for commercial deployment, including SA, NSA, NBIoT, etc.

At the end of the project, buildings, car parks and factories can benefit of 4G/5G based on a cost efficient solution vRAN for low power coverage (2x0.5W max). The software and hardware solution is available and mature.

Beyond coverage extension application, Rapid.Space partners can provide high power coverage in other areas, in particular as an altenative to traditional telecom infrastructure vendors. Rapid.Space RRH partners already manufactures mature 2x40W, 4x40W and RRH models, and have capability to design 8x40W RRH.
