Are you looking to buy a new Android smartphone but, reading your technical data do not understand some acronyms such as 3G, 4G, UMTS or LTE? Are terms that often we read, but what do they mean? Of course we here we, ready to give you, simply, all the relevant information.
We have often treated topics a bit difficult, terminologies are many, increasingly complex technology: this premise a must, this is a small guide dedicated to inexperienced and certainly not a feature article on the topic, in broad terms, just to see some signs that all too often we hear appoint without understanding the true origin!
3G or UMTS
Even if they are not, they are often used interchangeably, or almost. 3G is an acronym which means the third generation of smartphones, going to include all of those standards that can be considered in a cell at this level. For example, send emails, make video calls or, indeed, the use of UMTS. This acronym, itself an acronym for Universal Mobile Telecommunication System, indicates the evolution of what was once the GSM and is used in all those countries where, at one time, you would use the latter: so all of Europe, including Italy!
4G or LTE
With these two codes we go a bit forward in time, with a new generation of smartphone and notices. Just like the 3G, 4G indicates the fourth generation of smartphones that was implemented with technology LTE (Long Term Evolution) in turn evolution of the previous standard, including UMTS. The improvements can be found in a substantial number of elements, but what may affect the most is the speed of the internet, now greater in navigation that in the download.
And in practice?
OK, we outlined the concept, grain lines. But we who are girls practices we wonder what difference there is between a smartphone and a 4G, one that supports UMTS connectivity and one that has also the LTE. Obviously the fourth generation of devices is the newest, with higher specifications and is mounted, for example, on Samsung Galaxy S4, making navigation faster in general.
Obviously to surf 4G from your Android smartphone you must subscribe to an offer with your wireless carrier and buy a SIM 4G. Unfortunately you have to also take into account the spread, but not yet satisfactory, of 4G in Italy: If TIM has just arrived to cover about 300 cities, Vodafone is still around 40, 3 to 4 and Wind no one.
Do you have any other question about 3G, 4G, UMTS and LTE?
