Cel‑Fi 4G/5G Site Surveys & Signal Upgrades
Eliminate dead‑spots, boost productivity – keeping you connected, even in an emergency.
SUFFERING POOR GSM COVERAGE?
Why Reliable Indoor Mobile Network Coverage Matters
Poor mobile reception drains batteries, stalls EFTPOS and cloud apps, frustrates staff, students and visitors and can leave you without a lifeline in an emergency. Cel‑Fi is the only certified booster in Australia that’s approved by all three carriers: Telstra, Optus and Vodafone.
The Cel‑Fi smart repeater, combined with a professionally planned antenna layout, restores network coverage – legally and permanently.

Case Study - Western Sydney Co‑Working Space
Client type: Multi‑tenant co‑working facility in Western Sydney
Environment: Two‑storey co‑working space with metal roof and shipping‑container offices that blocked mobile signals.
Challenge: Tenants reported one‑bar reception and frequent call drop‑outs on all carriers, especially Vodafone 5G.
ARCS 3‑Step Assessment
Floor‑plan upload – client supplied a CAD floor plan which we imported into our survey app.
On‑site grid testing – systematic walk‑through capturing 4G & 5G RSRP/RSRQ for Telstra, Optus & Vodafone across Bands 1, 28 & 78.
60‑page diagnostic report – heat‑maps, signal histograms and antenna‑placement model delivered within 48 hrs.
Key Findings
4G coverage was largely acceptable (RSRP > ‑105 dBm) on all carriers.
5G Band 78 failed across 90 % of the ground floor (see orange/red areas).
Adequate external 5G donor signal on the roof enabled a repeater solution.
Recommended Solution
Deploy a Cel‑Fi G51 package:
1 × roof‑mounted donor antenna (Band 78)
1 × G51 network unit with remote monitoring
3 × interior panel antennas
Low‑loss coax + splitter
Outcome
Proposal accepted; installation scheduled. Expected to deliver full‑bar 5G coverage throughout the tenancy and future‑proof the site for additional carriers.
