Response Time
Usable outside but dead inside usually means building shielding; weak outside means a network problem; no coverage means a booster cannot help. Start with a signal check.
Anonymized hotel, warehouse, office, remote-camp and apartment profiles with measured RSRP, SINR and system configurations. Figures are planning references, not guarantees.
Representative projectNigeria · Hotel, 9 floors
A multi-band host with 12 ceiling antennas restored usable RSRP and SINR on every tested guest floor. The basement was excluded from this phase and treated as a separate design.
Representative guest-floor RSRP
−108 dBm→−84 dBm
Representative projectKenya · Warehouse, 6,200 m²
One dual-band high-power host and 14 service antennas delivered usable coverage along the main aisles, loading dock and mezzanine office.
Representative aisle RSRP
−103 dBm→−84 dBm
Representative projectGhana · Office, 5 floors
The office floors reached −83 to −89 dBm after commissioning. The basement car park remained weak and was recommended for a separate design.

A practical coverage guide for hotels and resorts: guest-room antenna counts, coated glass, remote-site donor design, phased installation and budget scope.
When outdoor RSRP is -95 to -110 dBm, the project is a donor-link design: antenna gain, mast height, cable loss and realistic indoor expectations.
Record RSRP, SINR, band and cell ID at the right outdoor and indoor points so a supplier can design a booster system instead of guessing.

Practical answers for distributors, installers and project buyers.
Start with the bands used in the destination market. Choose a single-band model for one known band, a dual-band model for the most common two-band coverage, and a tri-band model when three distinct bands or multiple operators must be served. Confirm the band plan before ordering.
Coverage depends on output power, antenna gain, building materials, ceiling height and the number of service antennas. Published figures are planning references; the final configuration should be confirmed by a site survey or a detailed floor plan review.
Yes. Logo, housing color and finish, packaging artwork, manuals and accessory kits can be customized. Artwork and sample approval are required before production.
MOQ depends on the model, customization scope and packaging. Please tell us the model and target market so we can confirm the MOQ and production schedule in the quotation.
Yes. We provide system diagrams, antenna placement guidance and configuration recommendations. For complex projects, we can review the floor plan and proposed Bill of Materials.
Tell us your requirements and we will provide the best solution for your business.
