If you think you talk on a mobile phone on GSM standard you're let's say partly wrong. All mobile operators worldwide switched to EGSM long time ago. They still mention GSM 900 as supported standard, but you make and receive calls on EGSM band today.
The story dates back the year 1984 when GSM or Global System for Mobile Communications was originally developed. Since then GSM has become an international standard for mobile service. Put it simply, thanks to it you’re able to talk on a mobile phone in any part of the world.
But nothing stays the same, so GSM does. It was extended for additional 10 MHz and was given the name of EGSM band.
EGSM covers larger frequency band range than GSM by 10 MHz. It allows for a more optimal allocation of the radio spectrum, which therefore allows for a larger number of subscribers. EGSM wider band also upgrades the connection quality immensely. Now wonder all cellular operators provide voice signal on EGSM today.
In spite of EGSM being most available standard both in and out of the city, people still happen to be out of the coverage. The reasons are numerous. There’re network blind zones in certain areas, the kind of terrain itself like mountains or hills can prevent you from picking up the signal, shielding effect in highly built up business regions when signal is simply reflected from glossy skyscraper surfaces prevent you from gaining it inside the building, and it’s the end of list.
So if you can’t talk on the phone without interruptions, you obviously need HiBoost EGSM mobile signal booster. It’s a small and smart device able to blast though walls and cover your home or office with smooth signal in seconds.
Since GSM has more narrow frequency band than EGSM, EGSM booster enhances signal both on EGSM and GSM standards. Moreover, the system also supports UMTS or 3G at 900 MHz frequency. More widespread 3G 2100 MHz standard prevails in the city, and some mobile operators send 3G data on 900 MHz to provide subscribers in rural areas with high-speed data as well.
Huaptec offers 4 EGSM signal booster models for various coverage areas – 200, 500, 1000 and 2000 m2. To choose the correct one measure the area where you face signal troubles. Coverage area of your booster should exceed your real area by up to 500 m2 (it depends on how strong the signal reception is outside your house) as walls, stairs, fences impede signal getting inside and decrease the power of the booster.
