No Signal? Find the Cause First
Not every no-signal site needs a booster. Measure the outdoor level and check the building first, so you do not buy equipment that cannot solve the problem.

Quick Answer
Measure outdoor RSRP first: usable outside but dead inside usually means building shielding; weak outside means a network coverage problem; no usable signal anywhere means a booster cannot solve it. The three cases need different answers, so separate them before discussing equipment.
Building shielding
Outdoor signal is usable, but indoor levels drop sharply because of concrete, Low-E glass or metal cladding. A booster with a properly planned indoor antenna system is usually the right answer.

The outdoor signal is already weak. A larger amplifier alone is rarely enough; the donor antenna, mounting height and feeder loss matter more than the host power.
See how to checkNo coverage at all
No usable signal on the roof or at any high point. A booster cannot create coverage; the site needs VoWiFi, satellite backhaul, private LTE or an operator-led solution.

Open toolOne submission, enough for a useful first review
You do not need a complete tender package. Send what you know; we will list what is missing.
- Outdoor RSRP at the proposed antenna position
- Indoor RSRP in the worst room or floor
- Operator, band and cell ID if available
- Floor plan or site photos and wall/roof material
- Area, floors and target coverage zones
Not sure whether a booster is worth it?
Send the indoor and outdoor readings plus site photos. We will identify whether it is case A, B or C, then explain what to measure next and whether the project is worth pursuing.

Share the site conditions and we will reply with a preliminary assessment and the measurements still needed.
Frequently Asked Questions
Still unsure about the site? Send what you know and we will identify what still needs measuring.
Can a signal booster fix a building with no outdoor signal?
No. A booster amplifies an existing signal; it does not create coverage. If no usable signal can be measured on the roof or at a high point, the site needs a different solution such as VoWiFi, satellite backhaul, private LTE or an operator-led base station.
What is the first number I should send?
Send the outdoor RSRP at the proposed donor antenna position, together with the operator and band if known. Without an outdoor reference, any equipment recommendation is only a guess.
Do you provide on-site installation?
We provide remote diagnosis, survey guidance, system design and commissioning support. Installation is normally carried out by the customer or a local installer; we provide the drawings, notes and remote support needed for the project.
How quickly will I get a reply?
We normally reply within one business day. A useful first reply depends on the outdoor level, site type, country/operator and photos or a floor plan.
