What is it?
Wi-Fi stands for Wireless Fidelity. It is a way of digital data transmission over radio channels IEEE 802.11b. Widespread in the world and growing steadily in Russia, this technique allows many users simultaneously to gain access to Internet (multiple wireless access). Wi-Fi today is rapidly evolving from a high-tech novelty into a common service, a life-forming product.
By virtue of this technology any customer of a hotel, restaurant or business-center gets mobile Internet access and freedom of movement across the hotspot.
Any holder of portable computer (notebook or palmtop), equipped with a Wi-Fi module, can gain access to Internet at a speed comparable with a powerful dedicated line (up to 11 Mbps). As there are no wires or modems involved, the connection to Internet network becomes much simplified.
What is IEEE 802.11b?
IEEE 802.11b is a technical specification defining the functioning of wireless local networks in the range of 11 Mbps using Direct Sequence Spread Spectrum.
How reliable is it?
Yes, Wi-Fi is reliable. As the wireless technology has been originally conceived for the military, the safety of wireless devices has been seen as imperative. The underlying technique called Direct Sequence Spread Spectrum (DSSS) features strong resistance to data corruption and interference.
How big is the hotspot area?
The hotspot’s coverage can achieve 160 m, which in most cases is sufficient to evenly reach all parts of a building. It should be noted also, that the user remoteness may vary depending on the number and nature of the obstacles (walls, metallic structures)
What customer equipment is needed?
You will need an electronic portable device (notebook, palmtop, smart phone) supporting Wi-Fi (wireless LAN 802.11.b). Nowadays, over 80% of produced portable units are provided with a built-in Wi-Fi adaptor (e.g. any notebook using technology Intel Centrino) If your notebook does not support this technology , you can always buy various types of Wi-Fi adaptors compatible with any portable computer (for more details, please consult the manufacturer of your portable electronic device)
