5.1 Overview
This chapter describes the LTE Device’s Network Setting > Wireless screens. Use these screens
to set up your LTE Device’s wireless connection.
5.1.1 What You Can Do in this Chapter
• Use the General screen to enable the wireless LAN, enter the SSID and select the wireless
security mode ( Section 5.2 on page 45 ).
• Use the More AP screen to set up multiple wireless networks on your LTE Device ( Section 5.3 on
page 51 ).
• Use the WPS screen to enable or disable WPS, view or generate a security PIN (Personal
Identification Number) ( Section 5.4 on page 53 ).
• Use the WMM screen to enable Wi-Fi MultiMedia (WMM) to ensure quality of service in wireless
networks for multimedia applications ( Section 5.5 on page 55 ).
• Use the Scheduling screen to schedule a time period for the wireless LAN to operate each day
( Section 5.6 on page 57 ).
• Use the Channel Status screen to check the noise levels of the wireless LAN channels ( Section
5.7 on page 57 ).
You don’t necessarily need to use all these screens to set up your wireless connection. For example,
you may just want to set up a network name, a wireless radio channel and some security in the
General screen.
5.1.2 Wireless Network Overview
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can connect with
numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and wireless clients,
extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or more wireless
clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to
one another in order to exchange information.
