As you know we all get bombarded with unlimited broadband offers on connections to the Internet: If the saving of O2, Virgin, Sky, advantages for customers of mobile. Important to bear in mind that it is not the same 20 Mb of ADSL 20 Mb by using optical fibre. As many of you know, or directly suffer, often the actual speed does not conform to the contract with the operator. The speed delivered us to the address depends on the technology used to transmit the signal: xDSL, HFC or FTTH.
All xDSL technologies used to reach the home subscriber cable copper pair, the more vulnerable to losses by the central distance. This is the technology used in the connections of Jazztel, Ya.com, Orange, Vodafone and Movistar. Lower speeds for ADSL, is used to the usual “up to 20 Mb” used ADSL2 + for the 20 Mb from Movistar or 30 Mb of Jazztel the technology used is VDSL.
Central speed/distance graph
The main factor that determines the speed that we will receive one of these connections is the distance from home to the plant that provides the service. The further we find ourselves less speed we will receive. The antiquity of the cable laid in the interior of the building or home also have its negative influence on reception.
The HFC is the famous optical fiber of Ono, for example, but that does not reach the home subscriber. In this case to the door comes a cable coaxial, also much more reliable than the copper pair but less than the fiber optic, although it says in the majority of cases a rate close to or higher than the offered. Regional as Euskaltel, R, Telecable or operators also make use of this technology.
And finally we have FTTH. This option optical fiber goes directly into the home so it is the connection that offers a more reliable speed and potential for increase in the future. Its implementation is still very tight to being MoviStar which momentum you is giving to this modality with connections to 50 or 100 Mb download speed. Other operators have experiences pilots with fiber to the home and even in the Principality of Asturias several basins mining have this connection thanks to public investment.
Coverage of the connection place
The first thing to consider is the coverage we have in our home or the place we go to require connection. Offers are many but it is very likely that, do not live in big cities, not we can access all of them. It is therefore advisable to consult, or through the websites of the operators themselves or in your telephone service if we have coverage of the company or until we can offer speeds.
Needs of each user
Not by chance to hire a speed necessary or compulsory to hire her, it all depends on the use that is going to make the connection. Therefore the more occasional users or who only want to check your e-mail, chat or check websites without too much load should be sufficient with 1 Mb down while a user fan of Youtube, streaming audio or video, or “Downloader” services would require at least 6 or 10 Mb connection. Gamers or even those who work from home should take into account the upload speed, requiring at least 1 Mb to be able to work or play without cuts.
