WiFi is a the another example of latest mobile phone technology, DRAADLOZE Merk in the hands of the Wi-Fi Alliance ter improving the extraction of DRAADLOZE. Often, applications for Wi-Fi Internet-access phone-in VoIP, games and netwerkconnectiviteit for consumentenelektronica as mobile phone, laptops, spelconsoles, MP3 players and PDAs. Of mobile telephony market has a lot of attention gekregen the last time the various operators over hele wereld are the different kinds of devices starting with users the ability to link te maken met the Internet via Wi-Fi iPhone latest example.
Mobile VoIP
A new study of a London-based research firm claims that mobile VoIP will be a great means of communication by the end of 2012, based on the rapid growth of voice over users without Over 3G. Disruptive Analysis said that its research shows mobile VoIP will eclipse the convergence of fixed and mobile services using dual-mode voice over Wi-Fi capabilities.
VoIP has become popular largely because the cost to the consumer benefits of traditional networks telepone. Calls can be placed through the Internet. Most Internet connections are charged with using a fixed fee structure. The use of the Internet connection for data and voice messages can allow consumers to get rid of a monthly payment. In addition, VoIP does not charge a fee per minute for long distances. For international calls, the savings for consumers to switch to VoIP technology can be enormous.
Today, Skype, a company called Truphone fring and already offers VoIP on 3G smart phones and 3G-enabled laptops, allowing users to communicate with other VoIP users via the Internet. This service is expected to provide customers a cheaper alternative for connecting calls via mobile phone in the near future.
High-Speed Downlink Packet Access (HSDPA) is a 3G (third generation) mobile communication protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) Data for greater transfer speeds and capacity. Current HSDPA deployments support connection speeds of 1.8, 3.6, 7.2 and 14.4 Mbit / s. Further rate increases are planned for the near future.
communication systems, is a term used to describe the next step in the development of wireless communications. A 4G system will be able to provide IP, where voice, data and multimedia can be streamed to the user on an "anywhere, anytime, and data at higher speeds than previous generations. There is no formal definition of what is 4G, but there are certain goals that are planned for 4G. These objectives are: 4G that is fully integrated IP-based system. This will be achieved after wired and wireless technologies converge and will be capable of 100 Mbps and 1 Gbps speeds both inside and outside, with premium quality and high security. 4G offers all types of services at affordable prices.
4G mobile data transmission rates are set at 20 megabits per second, or about 10-20 times faster than standard ADSL services.
In terms of connecting seed, 4G will be about 200 times faster than the current 2G mobile data rates, and approximately 10 times faster than 3G mobile broadband. Transmission rates of 3G data are currently 2Mbit/sec, moving very fast compared to 2G of 9.6Kbit/sec
