MiChoice Technology Systems Wireless Network Specifications

What is wireless networking?

A wireless local-area network (WLAN) uses Radio Frequency (RF) technology to transmit and receive data over the air, providing all the features and benefits of traditional LAN technologies but without the limitations of a cable. A wireless local-area network is a flexible data communication system implemented as an extension to, or as an alternative for, a traditional wired local area network.

Wireless local area networks are not the answer to all applications. Many factors can impact the performance of a wireless network; therefore MiChoice Technology, Inc. does not guarantee that a wireless local-area network will function properly in every installation. Some installations simply will not work with a wireless network, therefore the traditional wired network is recommended. We strongly encourage the district/school to consult with their network support staff or contractor to assist them in making the best decision on whether or not wireless is a suitable solution.
