Wireless networks are telephone or computer networks that use radio as their carrier or physical layer. It refers to technology that enables two or more computers to communicate using standard network protocols, but without network cabling.
The term wireless technology is generally associated with mobile IT equipment like cellular telephones and laptops. It is a method of data transmission, which is similar to wired technology. For both these technologies the range of transmission is the prime concern.
It generally refers to wireless LANs, the technology which was fuelled by the emergence of cross-vendor industry standards such as IEEE 802.11. This has produced a number of affordable wireless solutions that are growing in popularity with business and schools as well as sophisticated applications where network wiring is impossible, such as in warehousing or point-of-sale handheld equipment.
