:: KUBIWIRELESS :: WI-FI

Wi-Fi (IEEE 802.11b) technology permits the development of a radio-frequency network just like an Ethernet network but without the necessity of wires. Thus a user can access the network from the office, the terrace of a café or an airport in the same way as you listen to the radio from almost anywhere.

A Wireless Local Area Network (WLAN) is defined as a local network (LAN) that uses electromagnetic waves to communicate between equipments connected to a network in place of cables like coaxial, twisted pair or fibre optics for example. The IEEE 802.11b standard uses microwaves to establish the wireless link.

Local area networks based on 802.11 technologies are widespread in other countries like the USA or the Scandinavian countries. These networks are widely used basically due to the following factors:

        -Permit the mobility of the users (warehouses, hospitals and         hotels)
      -Permits the deployment of the network in places where cabling           would be very difficult (historical buildings, buildings with poor           infrastructure)
        -Permits interconnecting buildings
        -Are of great utility for ad-hoc meetings

The 802.11 standard operate en the 2.4Ghz frequency that belongs to the ISM (Industrial, Scientific and Medical) band. This band of spectrum is for free commercial use and does not require a license.
