Smart In-Building Cellular Coverage
Reliable indoor mobile signal for offices, hotels, retail, warehouses, residences and basements, using CEL-FI technology.
Overview
Full-Strength Mobile Signal Inside Every Space
Modern construction — dense concrete, low-emissivity glass, deep basements — blocks mobile signal exactly where people need it. CSC designs and installs Cel-Fi smart signal boosters and distributed antenna systems that lift indoor coverage without interfering with the operator network.

Which buildings is Cel-Fi suitable for?
Cel-Fi suits offices, hotels, retail, warehouses, residences, basements, parking levels, and tunnels. CSC selects the platform to the site: CEL-FI CONNECT C41 for homes and small businesses, GO G41 for small to medium sites, and QUATRA 4000e for enterprise buildings and campuses.
Does Cel-Fi interfere with the mobile operator's network?
No. Cel-Fi is a smart, carrier-safe signal booster designed to improve indoor coverage without interfering with the operator network. CSC designs and installs each system so it enhances the operator signal safely.
Which mobile technologies does Cel-Fi support?
Depending on the model, Cel-Fi supports 2G, 3G, 4G, and 5G NR, including multi-operator and multi-band coverage. CEL-FI GO G51 is designed specifically for mid-band 5G indoor coverage.
How do you confirm the coverage has improved?
Every project starts with an RF site survey and coverage mapping, and ends with post-installation validation testing. You receive coverage reports and documentation showing the signal improvement, plus options for maintenance and system tuning.
