Cell phone jammers and signal blockers in Spain
Mobile communications in Spain were first presented in 1976 and began with the so-called automobile radio phone, which was developed and supported by the Telefónica company. We should admit that the mobile communications market was created by that company, and all its features are the result of Telefónica's activity. It was a monopolist until 1994 and the only telecommunications company on the market.
That company was founded in 1924 and still holds the top position in the market. Its share in the telecom market is 75%. If to consider mobile communications, its market share is 41%. Nowadays, Telefónica provides cell phone service and communications under the Movistar trademark. In 1995, Airtel-Vodafone entered the Spanish mobile communications market, and in 1998, Amena-Orange joined them too. And in 2006, when the market became really competitive – Yoigo. And since 2001, lots of virtual mobile carriers have appeared in Spain, which uses mobile networks of the existing carriers.
GSM standard in Spain
According to the statistical data, in December 2011, the quantity of active mobile users in Spain reached the point of 58 million people; 42% of the population used prepaid GSM services, and 58% for postpaid. Mobile carriers in Spain have built a decent GSM network, which covers 98% of the country. As for the mobile communications standards, Spain uses the widely spread European GSM standard on 900/1800 MHz frequency. Also, major mobile carriers provide 3G services with UMTS and WCDMA standards, which use 2100 MHz frequency.
Now, a couple of words about mobile carriers in Spain. At the moment, there are four major mobile carriers, which have their own GSM network and decent coverage. They are Movistar, Vodafone, Orange, and Yoigo
MovistarThat company is a trademark of Telefónica. Now it has 22.8 million of active users, and its cell phone communications market share is 41.4%. That is the oldest company on the market.
VodafoneThat company is a representative of the world's biggest cell service carrier, the British company Vodafone. It has 15.9 million of active users, and its market share is up to 29%.
OrangeThe third among the major GSM and 3G carriers of Spain belongs to a French company named France Telecom. Now it has 11 million active users and 20.2% of the market share.
YoigoYoigo is the property of the international Finns-Swedish telecommunications company TeliaSonera, the youngest among Spain's major mobile carriers. It has 2.4 million active users, and its market share is 4.3%.
We've already mentioned fiction couriers. Their market share in Spain is 4.9% or 2.7 million users. There are nearly 40 such pages in Spain, they do not have a web, and they use the technology of one of those primary carriers. They sell their services under their trademarks.
There are two kinds of portable services in Spain: prepaid and postpaid. They are called Contract “Contrato” and Card “Tarjeta”. The Card option is a prepaid option. You will have to pay for the service before you use it, and the payment can be made with special terminals or various e-payments.
A Contract for mobile service is being signed for 12-18 months. It depends on the carrier and the option you've chosen. In that case, the client must provide the transportation with the data on his bank account, for which the mobile carrier will send monthly invoices. You should know that the Contract option is available to residents only, and only in case, you have a bank account in the local Spanish bank.
Blocking mobile signals
The jammer jams the incoming signal to spy devices. As a rule, this is the device's signal for activation. You can check the premises and the car and not find anything suspicious. While the device is "sleeping", it will not reveal itself. For activation, it receives an external radio signal easily blocked by the jammer.
For example, if a bomb is placed under a car's gas tank, it cannot be detected by technical means. Only with the help of grooming mirrors or trained dogs if explosives are used. At the right moment, the attacker sends a signal by phone or remote control - and the bomb explodes. Similarly, in some GSM bookmarks, fixed bugs are turned on to transmit information only after receiving a command from the outside. A radio suppressor eliminates this problem.
In conclusion, we may say that Spain has built its mobile communications networks fast, and the large quantity of mobile carriers works for the benefit of consumers because more competition means lower prices.
