VoIP and benefits of 3G

Mobile VoIP

A new study from a London-based research firm claims that mobile voice-over-IP will become a mainstream form of communication by the end of 2012, based on rapid growth of voice-over-3G wireless users. Disruptive Analysis said its research shows mobile VoIP will eclipse fixed-mobile convergence services that use dual-mode handsets with voice-over-WiFi capabilities.

VoIP has become popular largely because of the cost advantages to consumers over traditional telepone networks. VoIP calls can be placed across the Internet. Most Internet connections are charged using a flat fee structure. Using the Internet connection for both data traffic and voice calls can allow consumers to get rid of one monthly payment. In addition, VoIP plans do not charge a per-minute fee for long distance. For International calling, the monetary savings to the consumer from switching to VoIP technology can be enormous.

Today, Skype, TruPhone and a company called Fring already offer VoIP over 3G smartphones and 3G-enabled laptops allowing users to communicate with other VoIP users via the Internet. This service is expected to provide customers with a cheaper alternative to connecting calls via GSM in the near future.

HSDPA

High-Speed Downlink Packet Access (HSDPA) is a 3G (third generation) mobile telephony communications protocol in the High-Speed Packet Access (HSPA) family, which allows networks based on Universal Mobile Telecommunications System (UMTS) to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.4 Mbit/s. Further speed increases are planned for the near future.

4G Technology

4G, an acronym for Fourth-Generation Communications System, is a term used to describe the next step in wireless communications. A 4G system will be able to provide a comprehensive IP solution where voice, data and streamed multimedia can be given to users on an "Anytime, Anywhere" basis, and at higher data rates than previous generations. There is no formal definition for what 4G is; however, there are certain objectives that are projected for 4G. These objectives include: that 4G will be a fully IP-based integrated system. This will be achieved after wired and wireless technologies converge and will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors, with premium quality and high security. 4G will offer all types of services at an affordable cost.

4G is being developed to accommodate the quality of service (QoS) and rate requirements set by forthcoming applications like wireless broadband access, Multimedia Messaging Service, video chat, mobile TV, High definition TV content, DVB, minimal service like voice and data, and other streaming services for "anytime-anywhere". 4G in principle will allow high-quality smooth video transmission. It will enable fast downloading of full-length songs or music pieces in real time.
