The coverage area of a cell phone signal booster (e.g., Lintratek cell phone signal booster or GSM signal booster) depends on 4 key factors. Understanding these helps you choose the right model for your space:
1. Booster Gain (Amplification Power)
Gain (measured in dB) determines how much the booster amplifies weak signals. Higher gain = stronger coverage capability:
- Residential models repeater (15-50dB): Cover 50-500㎡ (e.g., small homes, apartments,Building,elevator).
- Commercial models repeater (50-70dB): Cover 500-5,000㎡ (e.g., offices, hotels,community).
- Industrial models repeater (70+dB): Cover 5,000+㎡ (e.g., factories, large campuses,tunnel,rural area).
Note: But knowing only the coverage area is difficult to determine which Lintratek’s network mobile signal repeaters you should use, and it also needs to be combined with the actual coverage scenario, whether factors such as rooms, building walls will cause equipment attenuation, and the actual number of antennas used.
2. Outdoor Signal Strength
The booster relies on capturing external signals from cell towers. Better input = larger coverage:
- Strong input (-50 to -80dBm): Booster performs at full capacity, reaching maximum rated area.
- Weak input (-80 to -110dBm): Coverage shrinks by 30-50% (e.g., a 500㎡ booster may cover only 250㎡).
- No input (<-110dBm): Even powerful boosters fail—use a long range fiber optic outdoor repeater to capture distant signals first.
3. Antenna Type & Placement
- Outdoor antenna: Directional antennas (e.g., Yagi) focus on distant towers, ideal for weak signals; omnidirectional antennas capture signals from all directions but have shorter range.
- Indoor antenna: Panel antennas cover narrow, long areas (hallways); ceiling-mounted antennas spread signals evenly in open spaces (offices); dome antennas work best for multi-room coverage.
Example: Pairing a Lintratek GSM signal booster with a high-gain directional outdoor antenna can extend coverage by 20-30% in rural areas.
4. Building Structure & Obstacles
Walls, metal, concrete, and appliances (microwaves, routers) block signals, reducing effective coverage:
- Wooden/drywall buildings: Minimal signal loss—booster covers near its rated area.
- Concrete/metal structures (basements, parking lots): Signal weakens by 50-70%—need higher gain or additional indoor antennas.
- Multi-story buildings: Each floor reduces coverage by 10-20%—use a multi-antenna system for full building coverage.
