Which devices will this Cell Booster amplify the signal for?

Teleray is compatible with all mobile devices and GSM routers, supporting any device equipped with a SIM card. It operates seamlessly across all major mobile networks, including MTN, Cell C, Vodacom, and Telkom Mobile.  

Why do I need this device?

We can think of three reasons: better talk, text and internet guaranteed. We’ve all struggled with weak signals and unclear calls- this booster eradicates those issues.

How does a Cell Booster work?

It’s quite simple. A Cell Signal Booster utilises 3 easy-to-install components to function.

The Outside Antenna draws in weak 3 and 4G LTE Signal, which is then boosted up to 32 times by the Amplifier before being rebroadcasted throughout the area by an Inside Antenna.

Do Cell Boosters also enhance Wi-Fi signal?


Yes, signal boosters enhance cellular signals, particularly for 3G and 4G LTE, when connected to a router. However, it’s important to note that they do not improve Wi-Fi signals. The external antenna captures weak 3G and 4G LTE signals, amplifying them up to 32 times with the amplifier, and then redistributes the strengthened signal throughout the area via an internal antenna.

What is the radius of the device?

The coverage radius of the device depends on the signal strength. It is designed to provide coverage for buildings up to 1000 square meters on 3G and 4G LTE networks. With a potential gain of up to +70dB, the device can amplify the cellular signal up to 32 times.

Which factors would contribute to me having a weak signal?

A weak signal is generally caused by one of 5 key factors. A single or combination of said factors can greatly affect your cellular coverage.

These include cell tower distance, outside interference (such as trees, mountains or high structures), building material, internal interference and the weather.

Do Cell Phone Boosters need an Internet connection?

No. Signal boosters simply amplify your existing 3G & 4G LTE signal.

What are the steps required in a typical process of installation?

This is traditionally a 3-step process.

The Outside Antenna is first installed high up, usually on the roof of your home or building. Next, the Amplifier is installed at an easy-access location, before the Inside Antenna is installed in whichever area requires an improved cellular signal.


Thanks to TeleRay’s solution Duinbaai perimeter fencing is now operating well with no signal interruptions. Both networks now have full signal.

We cannot agree more with Rayne when he says: “When installing cellular boosters, I spend a lot of time on antenna selection. When you choose the right antenna, the rest is easy! A cellular booster can only perform as well as the antenna you choose and how well it is installed.”

Came across Rayne of Teleray and immediately felt comfortable with him. Must say his knowledge and advice were excellent. I went with his quote and must say his installation was good and the units he uses are aesthetically pleasing. Had load shedding first night of installation and everything worked as it should have and was most happy with the work Teleray carried out. I have no qualms in recommending Rayne for your Inverter needs.
