Figure 5-1 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B
use the access point (AP) to interact with the other devices (such as the printer) or with the
Internet. Your LTE Device is the AP.
Every wireless network must follow these basic guidelines.

Radio Channels
In the radio spectrum, there are certain frequency bands allocated for unlicensed, civilian use.
For the purposes of wireless networking, these bands are divided into numerous channels.
This allows a variety of networks to exist in the same place without interfering with one
another. When you create a network, you must select a channel to use.
Since the available unlicensed spectrum varies from one country to another, the number of
available channels also varies.
A channel is the radio frequency used by wireless devices to transmit and receive data.
Channels available depend on your geographical area. You may have a choice of channels (for
your region) so you should use a channel different from an adjacent AP (access point) to
reduce interference. Interference occurs when radio signals from different access points
overlap causing interference and degrading performance.

Every device in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set Identifier.
If two wireless networks overlap, they should use a different channel.
Like radio stations or television channels, each wireless network uses a specific channel,
or frequency, to send and receive information.
Every device in the same wireless network must use security compatible with the AP.
Security stops unauthorized devices from using the wireless network. It can also protect
the information that is sent in the wireless network.
