In the early years, the development of wireless local area network was slow, and it was difficult to promote and apply it, mainly due to the low transmission rate, high cost, limited product series, and incompatible products of many products. For example, the rate of wireless local area network in the past was only 1~2Mb/s, and many applications were also designed based on the 10Mb/s Ethernet rate, which limited the application types of wireless products. In view of the rapid growth of data services and multimedia services, the key to the progress of wireless local area networks lies in the formulation of new high-speed standards and the emergence of 10Mb/s or even higher rate products based on this standard. 802.11b fundamentally changes the design and application status of wireless local area networks, satisfies people's needs for uninterrupted mobile office in a certain area, and creates a free space for us.
