Cellular technologies have taken a quantum leap in the last 1,5 decade. The introduction of GSM (short for: Global System for Mobile Communications) is generally acknowledged as the real start of Cellular technology. Other cellular technologies have preceded GSM, as such GSM is reffered to as 2G.
Complex technologies are often the result of a serious period of developement, lab-testing, trial field testing, deployment and finally commercialization. With every major technology improvement this process repeats itself.
Telephony caused the telecommunications industry to take off, and has grown from an all analog technology to a full digital technology in the last 40 years, not equally distributed over all telecomms areas and involvements. Somewhere in this last 40 years period datacommunications was introduced as a ‘computer equivalent’ of human tele-communications. Datacommunications pushed the telecommunications evolution in the last 15 years to new heights. Transmissions rates had to be rapidly upgraded to facilitate the exploding need of exchanging information since the start of the Internet era. Ofcourse the initial focus was on fixed line communications, but since the invention of the smartphone at the end of the first decade in the 21st century the stress is even more on mobile communications.
UMTS (3G) was the first real digital mobile technology, end to end. This was a challenge to the telecommunicatoins industry. Chipsets had to produced that supported still GSM (partly analog) and UMTS (all digital) technology. Data communications bandwidths started off with 384 kb/s and grew in 6-7 years time to even 28.8 Mb/s download and 5.7 Mb/s upload bandwidths and latencies dropped till 300-500 mS.
A few years ago 4G was introduced, known as LTE (Long Term Evolution) as being the foundation of a true all digital technology, end-to-end. LTE is making big steps in just a few years, speeds of more than 100 Mb/s download are possible through the newest LTE-Advanced chipsets and networks. Lower latencies like 100-200 mS (under load) are normal and this makes it possible that normal office applications can be made accessible everywhere. Soon LTE will be used to support voice as well (VoLTE).
Making use of full LTE advantages requires an optimum situation. That is in terms of proximity of a cell tower, number of LTE users around you, circumstancial factors as atmospheric conditions, free sight, geographical conditions, time of the year (leaves on trees, rain..), happenings on that location, inside building, type of wall(s)/roof, road traffic, etc. etc. Too many factors that make the bandwidths dependent on too many uncontrolable factors.
When you are in need of a helping hand for a better mobile signal, than you have come to the right place.
