Although mobile phones have been able to access the internet for some time now, the experience still falls far short of that which is available on desktop and laptop computers. Currently, there are four types of mobile connection to the internet: GPRS, EDGE, 3G, and HDSPA.
GPRS(General Packet Radio Service) is the slowest type of web connection available to mobile phone users, at a rate of 128kbps, which is the equivalent of dial up. The next step up is EDGE (Enhanced Data rates for Global Evolution), which at 236kbps is almost double the speed of GPRS.
The most common type of connection nowadays, however, is 3G(third generation), which is often compared to a broadband connection, although it is only three times faster than GPRS and considerably slower than the 1mbps achieved by most standard broadband connections.
HDSPA, an update to the 3G standard, is the fastest yet, and can claim a theoretical maximum speed of 14.4Mbps, although in reality, it only offers a slight speed improvement over a standard 3G connection. However, once the old 2G transmitters are taken down, as they already have been in Japan, then we can expect to see an improvement in the performance of 3G and HDSPA connections.
If you are disappointed by the quality of internet access that you can achieve through the mobile networks, you may be heartened to learn that some newer mobile phones are also able to connect to the internet via the proven Wi-Fi transfer protocol.
The one drawback with Wi-Fi is that it is not available everywhere, and you are often required to buy a hot beverage or join a library in order to use it on the providers premises.
One major problem with accessing the internet on mobile phones is that most web pages have been designed with much larger screens in mind than are available on most mobiles, although there are some websites, such as FaceBook and Twitter, that have special mobile versions available.
Some of the newer smart-phone PDAs have tackled this problem with large touch sensitive screens and tracker balls, which at least lessen the resolution and navigation problems inherent in surfing the web on a mobile phone.
However, few of them can deal with having multiple windows, and some popular sites are completely inaccessible to mobile phones for coding and copyright reasons.
The mobile internet may have a bright future ahead of it, but it cannot be said to be quite there yet, although things are improving steadily.
