Wireless technology confuses users

Many technologies have appeared to realize people's dreams. However, then they cause problems of compatibility and complexity of the specifications. Wi-Fi is also not better.

" This Internet-connected technology promises great promise and no one doubts it will become so unbelievable, " commented Doug Loewe, an expert with iPass wireless security. " Just a few years ago, the world had about 5,000 access points and now this number is over 50,000. Hotspots are open everywhere because they not only meet the needs of businesses but also consumers. ".

But the Wi-Fi world is full of words and complex numbers like 802.11a, 802.11b, 802.11g and 802.11n. 802.11 confirms to users that they have wireless access and what the letter at the end of that standard message can do.

" The digital world has required 10, 11, 12 Mb of data transfer per second, but 'b', 'g' and their variants have not yet done that. approved, it may cause problems that we witness today, "said Rob Falconer of Belkin.

When Wi-Fi starts to appear, the coverage, speed and applicability of this technology are "problematic". In June 2004, IEEE began to study the parameters, but after two years, they still had no agreement. Information on the organization's website confirms that 802.11n will not be complete until July 2007.

The technology community is embracing the idea of ​​covering the entire city and town with Wi-Fi connectivity, such as installing them on streetlights. However, they also noticed another technology, WiMax with 802.16, which has a wide range.

" WiMax also has many different variants. South Korea has now established a standard called WiBro. Meanwhile, 802.16D promises to replace cables and has been used in a number of railway companies to allow 802.16E is designed specifically for mobile devices, but has not been officially approved , said Guy Kewney of Newswireless.net.

In general, the popular Wi-Fi technology currently only meets half the needs of users, WiMax has not really been deployed and 3G - another wireless technology - is also struggling to attract customers. line. " It will be time for all three standards to combine and complement each other. No technology will prevail because they are fully compatible with each other, " Doug Loewe predicts.
