Filter for installation of digital and analog TV antenna (DVBT or TDT). Filters and eliminates the signals of mobile telephony LTE, GSM and 4G. It connects between the antenna and the TV receiver (TV, decoder, etc.). It has female F connectors at both ends (female for the entrance and exit). Shielded to avoid interference. Compatible with frequencies 5-790 MHz. Maximum pass of 300 mA.
The global system for mobile communications (English Global System for Mobile communications, GSM, and originally from the French groupe spécial mobile) is a standard system, royalty-free, digital mobile phone. A GSM client can connect through your phone to your computer and send and receive emails, faxes, surf the Internet, access to the computer network security acompany (LAN/Intranet) and use other functions of digital data, including short message service (SMS) or text messages. What are the differences between GSM and UMTS? The GSM system operates by TDMA, ie, time is divided into slots and each user is assigned a slot, ie, a period for which data can be transmitted. Therefore each channel is shared by a ndetermined number of users. The system is a UMTS (WCDMA) code division multiple access broadband. In this system there are no time slots and GPRS. All users transmit simultaneously on the channel, but each user signals are encoded with a unique code so that even though we think that an "indecipherable signal" is formed by using the same frequencies simultaneously, It is not toyes, because the base station is capable of decoding and re perfectly separate each of the communications received from different users. This obviously implies a much higher channel utilization, to not share in time.
ng-Lee used in Europe for terrestrial receivers. It requires a little more attention to the correct installation of the cable male with Belling-Lee type and should be attentive to the quality of the connector and match the size of connector cable.
TV antenna filter for 4G Why a filter for 4G antenna? With new government regulations, the new DTT and mobile phones use the same 4G technology. Therefore, the 4G antenna filter can prevent interference that might be caused by mobile phone to the TV. The filter is placed enters the TV and the antenna.
4G is the next generation of technology that the International Telecommunication Union has created for transferring data via the Internet. The speed is 100 MB/s downstream and 50 MB/s upstream, with a bandwidth of 20 MHz. The idea that used to wield the great value of 4G format that society is consuming more video and heavy images and this will make the mobile phone supports it. A continuación show you a small graphic comparison between 3G and 4G in the most common uses computer-related.
