WiFi Technology

What is Wi-Fi?

WiFi is a wireless technology brand owned by the Wi-Fi Alliance intended to improve the operating of wireless products. Common applications for Wi-Fi include Internet and VoIP phone access, gaming, and network connectivity for consumer electronics such as mobile phones, laptops, game consoles, MP3 players and PDA's. Wi-Fi also allows connectivity which enables devices to connect directly with each other. This connectivity mode is useful in consumer electronics and gaming applications.

It's faster and has a greater range than Bluetooth, and is ideal for home or office connectivity. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires. The easy access of emails for business orientated individuals is also a bonus, as urgent messages can be downloaded on the go once the email settings are configured on to the WiFi enabled handset.


The mobile phones market has received a lot of attention lately as several operators across the world have launched various types of handsets which allow users to connect to the Internet via Wi-Fi, the iPhone being the ultimate example.

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.
