Institute of electrical and electronic engineers, known as IEEE which is the most popular all around the world, set a group of WiFi technology specifications. They specify the speed, frequency bands (2.4 GHz and 5.7 GHz), security, authentication and interoperability between different networksÖ etc., some of these specifications are under development.
The IEEE802.11 standards Specifies an 'over-the-air' interface between a wireless client and a base station or access point. They are 12 standards that address the first two layers of OSI model; PHY and MAC layers.
Some analysts see that WiFi is a competing technology with the evolving 3rd generation mobile services when applied in the public domain.
Users at public areas; such as airports, clubs, hotels, cafťs, etc., can enjoy wireless connectivity on the move or while sitting on the rim of a swimming pool!
WiFi permits high-speed wireless connectivity between note book PCs or wireless enabled PDAs (Personal Digital AssistantĖa hand held organizer or pocket PC having wireless capability) to each other or with the internet. It can support data rates up to 54 Mbps, for that it is considered one of the broadband technologies.
The WiFi technology itself has passed a great deal of standardization processes.
IEEE 802.11x series of standards are now being widely accepted, but still subject to enhancements from time to time, particularly in the area of security, interoperability and roaming issues.
