Weak mobile signal is a common problem in many buildings and project sites across Saudi Arabia. Thick reinforced concrete walls, underground structures, metal materials, elevator shafts and thermal insulation glass can block or weaken outdoor cellular signals. As a result, users may experience dropped calls, unstable 4G/5G data, poor indoor reception or no mobile signal in basements, warehouses, hotels, villas, shopping malls, offices and underground parking areas.
Callboost provides custom mobile signal booster solutions for Saudi Arabia, including [4G signal boosters], [5G signal boosters], high-power cellular repeaters, [fiber optic repeater solutions], antennas, coaxial cables, splitters, couplers and RF accessories, and complete indoor coverage system design.
Our solutions can be used for projects in Riyadh, Jeddah, Dammam, Makkah, Madinah, Khobar and other cities across Saudi Arabia.
Why Saudi Buildings Need Signal Booster Systems

In Saudi Arabia, many buildings are designed with thick concrete structures and heat insulation materials to handle high-temperature environments. These materials help building performance, but they also reduce cellular signal penetration.
Common weak-signal areas include:
Villas and private houses
Hotels and serviced apartments
Warehouses and logistics centers
Shopping malls and offices
Factories and industrial buildings
Basements and underground parking areas
Remote project sites
A professional mobile signal booster system receives the available outdoor signal, amplifies it through a repeater, and distributes the improved signal indoors through ceiling antennas or panel antennas.

Complete Mobile Signal Booster System

A real building coverage project usually requires more than one booster device. A complete Callboost system may include:
Outdoor donor antenna
Signal booster / cellular repeater
Indoor ceiling antenna
Indoor panel antenna
Coaxial cable
Power splitter
Directional coupler
RF connector
Lightning protector
Optional fiber optic repeater for long-distance coverage
The outdoor antenna receives the available signal from the cell tower. The repeater amplifies the signal. Indoor antennas distribute the improved signal inside the building. Splitters, couplers and coaxial cables help divide and balance signal power across different indoor zones.
This is why a warehouse, hotel, commercial building or underground parking project cannot be solved by randomly buying one amplifier. The antenna layout and RF distribution design matter as much as the booster itself.
For complete system configuration, Callboost can provide outdoor donor antennas and indoor service antennas, coaxial cables, splitters, couplers, connectors and other RF accessories.
Recommended Callboost Models for Saudi Arabia Projects
Different projects require different booster power levels. The correct model depends on outdoor signal strength, coverage area, building layout, operator frequency band, cable length and indoor antenna quantity.
1.Small Homes, Villas, Shops and Offices
Recommended product levels:
CB65G Single Band Signal Booster
CB65B Triple Band Signal Booster
CB68W-EU5B Five-Band Signal Booster
CB70W Single / Dual / Triple / Four-Band Signal Booster
Typical reference:
CB65G: about 60dB gain, typical coverage around 300 m²
CB65B: triple-band model, typical coverage around 300 m²
CB68W-EU5B: five-band model, typical coverage around 600 m²
CB70W: 70dB class model, typical coverage around 600 m²
These models are suitable for homes, villas, retail shops, small offices and small indoor weak-signal areas.
2.Medium Buildings and Multi-Zone Coverage
Recommended product levels:
CB75B Triple Band Signal Booster
CB75D Dual Band Signal Booster
CB75B Five-Band Signal Booster
CB75B Triple Band reference:
Downlink output power: 27±2dBm
Downlink gain: 75±2dB
Uplink gain: 70±2dB
Typical coverage: about 1000 m²
MGC: 1dB step, 31dB adjustable range
ALC: ≥25dB
Connector: N-Female
Power supply: DC 12V/2A
A typical CB75B solution may include one 11dBi outdoor antenna, three indoor ceiling antennas, LMR400 coaxial cable, a 3-way splitter and RF connectors.For better system stability, uplink and downlink gainshould be properly balanced.
3.Warehouses, Hotels and Commercial Buildings

For larger projects such as warehouses, hotels, factories, shopping malls and commercial buildings, higher output power and stronger system design are required.
Recommended product levels:
CB85B Series 2W Signal Booster
CB90C Series 5W Signal Booster
CB95C Series 20W Signal Booster
Typical reference:
CB85B: around 85dB gain, usually supports 6–12 indoor service antennas
CB90C: 37±2dBm downlink output power, around 90dB gain, typical coverage around 6000 m², usually supports 10–20 indoor antennas
CB95C: around 95dB gain, 43dBm downlink EIRP class, 20W high-power engineering solution, usually supports 20–30 indoor antennas
For a CB90C project, a typical system may include a 15dBi outdoor grid antenna, 10 indoor ceiling antennas, 1/2” coaxial cable, splitters, couplers and RF connectors.
4.Large Projects and Long-Distance Coverage
For very large buildings, tunnels, industrial parks, remote sites or large underground areas, long coaxial cable runs may cause high signal loss. In these cases, Callboost can provide [digital fiber optic repeater solutions] such as CR90F and CR95F.
CR90F / CR95F systems use MU/RU architecture:
MU: Master Unit
RU: Remote Unit
Optical fiber transmission
Remote indoor or outdoor coverage
Key advantages include long-distance transmission, lower loss than long coaxial cable, multiple remote unit expansion, digital RF processing, uplink noise suppression, ALC power control and optical delay calibration.
Frequency Band Confirmation for Saudi Arabia
Before choosing a mobile signal booster for Saudi Arabia, the most important step is confirming the local operator frequency band. A booster must match the actual network bands used by the local operator.
Customers should confirm:
City and project location
Mobile operator: STC, Mobily, Zain or others
Required network: 2G / 3G / 4G / 5G
Actual frequency band
Outdoor signal strength
Coverage area
Building structure
Indoor antenna quantity
Callboost products can support mainstream 3GPP bands such as:
B1 / B2 / B3 / B4 / B5 / B7 / B8 / B20 / B28 / B40 / B41 / B78
For 5G projects, B78 is often important in many markets. Callboost B78 options can support 3300–3600MHz and 3600–3800MHz ranges, depending on the project requirement.
Why Choose Callboost
Callboost boosters use aluminum alloy housing, good heat dissipation design and intelligent RF control software. These features are suitable for demanding project environments, including high-temperature areas in the Middle East.
Key technical functions include:
Real-time isolation detection
Self-excitation elimination
Automatic shutdown under severe oscillation or overload
Uplink sleep mode
MGC manual gain control: 1dB step, 31dB range
ALC automatic level control
Low noise and low radiation design
LCD display
These functions help improve indoor mobile signal while reducing the risk of overload, oscillation and interference to the base station.
