Cellphones have become an indisputable part of modern lifestyle, you cannot avoid them as they assist us in many of our daily tasks. So, the quality of cellular signals are equally important to ensure good cellular service and any drop in it is unacceptable. One of the best ways to ensure good quality signal reception is to use a cellular signal booster. These devices are made up of three elements, namely: external antenna, amplifier and internal antenna. Basically, it is a repeater system that ensures you get optimal reception at places where you install them. Shared below are some important points about the installation and operation of these devices.
Effect Of Outside Temperature On The Performance of Cellular Signal Booster
Usually the outside temperature doesn’t have much effect on the performance of signal boosters and pretty much works in any temperature. Their normal operational range of ambient temperature is between -20 °C to +70 °C, and anything outside this is considered to be extreme. But, if there happens to be the accumulation of materials on the casing that can either increase or decrease the temperature like ice or hot items, it is advisable to remove them to ensure optimal working temperature.
Customer Registration Of Their Cellular Booster
The responsibility of using cellphone booster is upon the customer and failing to do it can result in fines. When you buy the device, it will be clearly mentioned on the packaging and user instruction manual. These devices are meant for individual uses, in most cases you cannot use them without registering with the carrier and usually it is provided by carriers or vendors affiliated to them.
The primary reason for mandatory registration with the carrier is to ensure that the cellular booster is not faulty. Because, a faulty device can damage the carrier’s cellular tower and can affect their service. In such a scenario, the customer is held responsible and the dealer is not, this is because it is the sole responsibility of the user.
dB Or Decibel Gain
Decibel is the unit of measurement of radio signal frequency, decibel gain is a measure of increase in signal strength relative to the device and this is indicated by negative decibel number. So, the optimum signal strength near a cellular tower is -50 dB and for dead zones it is -110 dB. When it comes to a cellular signal booster, decibel gain is the relative signal boost or enhancement that the device is capable of providing. So, the higher the gain the better will be signal enhancement and greater coverage area.
Measuring Cellular Signal Strength Using Your Smartphone
In android phones go to the settings and in the search type in SIM status, in the SIM Status section touch on the active SIM slot. This should show you a list carrier network parameters, there will be a section for Signal strength and it will be in -dBm asu. This reading is on the negative side of the number scale and the further you move away from zero the weaker the signal. A minimum of -100 dBm is needed for data transfer, anything lower than that i.e. -110, -115, -120 and so on is bad or worse.
Adjustable dB Gain
As mentioned in the introduction, cellular signal booster is basically a repeater system and the purpose of it is to get usable cell signal strength in different locations of a building. This does not mean that the signal strength is not the same everywhere and it can vary, so depending on the requirement the gain is incremented by 1 dB. This ensures that the connectivity is evenly distributed avoiding sudden drop when moving from one point to another.
The Separation Distance Between Inside And Outside Antennas
The main reason for having a separation between the inside and outside antenna is to avoid positive feedback loop or oscillation, this can also affect the functioning of the carrier’s cellular tower. Also, the stronger the outside signal the more separation and vice versa, shared below are the minimum separation distance based on booster gain.
- 20 dB booster = 2 ft to 3 ft
- 30 dB booster = 4 ft
- 40 dB booster = 6 ft
- 45 dB booster = 15 ft
- 55 dB booster = 55 ft
- 65 dB booster = 70 ft
- 68 dB booster = 80 ft
- 70 dB booster = 125 ft
This can slightly vary depending on materials i.e. building materials between the outside and inside antennas of the cellular signal booster.
Do You Need A Line Of Sight Of The Cellular Tower To Use A Cellular Signal Booster?
You don’t need to have a direct line of sight to use a cellular signal booster, they are meant to operate where the signal strength is low and in most cases this is when the location is far away. The only factor that you must really take into consideration is the placement of internal and external antennas.
We hope that the aforementioned details will help in your installation of your cellular booster.
