Mobile signal boosters are essential devices designed to enhance the quality of mobile signals in areas with weak reception. These boosters are particularly useful in the United Kingdom, where diverse geographical landscapes and urban structures can often impede signal strength. This detailed guide explores the functionalities, benefits, and specifications of mobile signal boosters that operate on the 700/800/900/1800/2100 MHz i.e., 700 MHz, 800 MHz, 900 MHz, 1800 MHz, and 2100 MHz frequencies.

Carriers and Frequencies

In the UK, several major mobile carriers provide services across different frequency bands. The key carriers and their associated frequencies are:

  • EE: Utilizes 800 MHz, 1800 MHz, and 2100 MHz frequencies.
  • Vodafone: Operates on 800 MHz, 900 MHz, and 2100 MHz frequencies.
  • O2: Uses 800 MHz, 900 MHz, and 2100 MHz frequencies.
  • Three: Primarily operates on 800 MHz and 1800 MHz frequencies.

Types of Signals Boosted

These mobile signal boosters enhance various types of signals, including:

  • 4G LTE: Primarily operating on 700 MHz, 800 MHz, and 1800 MHz frequencies.
  • 3G: Predominantly on 900 MHz and 2100 MHz frequencies.
  • 2G: Usually on 900 MHz and 1800 MHz frequencies.

Coverage Areas

Mobile signal boosters come in different models, each designed to cover varying areas. The available coverage options include:

  • 300 SQM: Ideal for small apartments or individual rooms.
  • 500 SQM: Suitable for larger apartments or small offices.
  • 1000 SQM: Perfect for medium-sized homes or office spaces.
  • 2000 SQM: Designed for large homes, bigger offices, or small commercial establishments.
  • 5000 SQM: Best for large commercial spaces, warehouses, or multi-storey buildings.

Certification and Compliance

All the mobile signal boosters discussed here are CE and RoHS certified. These certifications ensure that the products meet European safety, health, and environmental protection requirements:

  • CE Certification: Indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area.
  • RoHS Certification: Restricts the use of specific hazardous materials found in electrical and electronic products.

Installation and Usability

One of the main advantages of these mobile signal boosters is their ease of installation. The typical installation process involves:

  1. Outdoor Antenna Installation: Mounting the external antenna in an area with the strongest signal, usually on the roof or an outside wall.
  2. Indoor Unit Setup: Connecting the indoor unit to the outdoor antenna via a coaxial cable.
  3. Powering Up: Plugging in the booster and adjusting the antennae for optimal signal reception.

Additional Features and Benefits

  • Automatic Gain Control (AGC): Ensures that the signal booster operates at optimal performance by automatically adjusting the gain based on the incoming signal strength.
  • Wideband Support: Capable of boosting multiple frequencies simultaneously, ensuring comprehensive coverage across different carriers and signal types.
  • LCD Display: Some models come with an LCD display to help with installation and monitoring of signal strength.
  • Energy Efficiency: Designed to consume minimal power while delivering maximum signal enhancement, contributing to reduced electricity bills.
  • Durability: Built to withstand various environmental conditions, ensuring long-lasting performance.


In conclusion, 700/800/900/1800/2100 MHz mobile signal boosters are invaluable tools for enhancing mobile connectivity in the UK. They support multiple carriers and frequency bands, cater to various coverage needs, and comply with stringent safety and environmental standards. With features like automatic gain control, wideband support, and ease of installation, these boosters provide a reliable solution for overcoming poor mobile signal reception. Whether for a small apartment or a large commercial space, there is a signal booster model available to meet every requirement.
