In-building wireless coverage
The building has a signal problem; the operator network is not going to fix it on its own. This page covers who buys in-building coverage, which architecture fits which building, and what we supply for each — from a single off-air repeater to a multi-operator fibre system.
How big is this market
Figures come from published third-party market research, with the source named under each one — we do not publish numbers we cannot trace.
Which architecture for which building
There are three ways to fix in-building coverage, and the wrong one is expensive to undo. An off-air repeater is cheapest and fastest: it amplifies a donor signal from the operator network and serves the building from an internal antenna. An active DAS (BDA) is the engineering answer for large or multi-operator buildings: a master unit distributes to slave units over fibre, giving each carrier independent control. A multi-operator co-construction system goes further and carries several carriers on one fibre path, which is what makes it economical in a building where four operators all need coverage.
- Number of operators on site
- One operator → off-air repeater; several → active DAS or co-construction
- Building size and depth
- Large or deep buildings need a distributed system, not a single amplifier
- Coverage type
- Voice and data on licensed public bands; carrier-grade units for operators
- Our cellular models
- CV510 / CV520 / CV530 off-air band-selective (LTE B3, software-configured)
What we supply for in-building coverage
Three families cover most in-building work: the CV510 / CV520 / CV530 off-air band-selective cellular repeaters (LTE B3, band and bandwidth set in software); the KT-F / KT-A multi-band multi-operator fibre systems, where one fibre path carries several carriers; and the digital repeater series for narrowband and public-safety users in the same building. Private LTE and 5G NR variants are configured per project.

Common questions
Do we need the operator’s permission to boost a signal?
Usually yes, and it is the first thing to sort out. In most markets an in-building system needs a written agreement with the operator whose spectrum is being amplified, and that agreement can take longer than the hardware. Tell us the operator and we will tell you what to ask for.
Repeater or active DAS — how do we choose?
A repeater is the right answer for one operator and a moderate building. A distributed system is the right answer when several operators need coverage, when the building is deep, or when the traffic is carrier-grade. We size it with you rather than defaulting to either.
Can we get a quote with the model list?
Yes — pick the models on our model list, tick them and send the list. Models with a datasheet on file can be claimed immediately; the rest we confirm internally and send with the quote.
