Many types of encryption use a key to protect the information in the WiFi network. The longer the key,
the stronger the encryption. Every device in the WiFi network must have the same key.

7.11.4 Signal Problems

Because WiFi networks are radio networks, their signals are subject to limitations of distance, interference
and absorption.
Problems with distance occur when the two radios are too far apart. Problems with interference occur
when other radio waves interrupt the data signal. Interference may come from other radio
transmissions, such as military or air traffic control communications, or from machines that are
coincidental emitters such as electric motors or microwaves. Problems with absorption occur when
physical objects (such as thick walls) are between the two radios, muffling the signal.

7.11.5 BSS

A Basic Service Set (BSS) exists when all communications between WiFi stations or between a WiFi station
and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between WiFi stations in the BSS. When Intra-BSS traffic blocking is disabled, WiFi
station A and B can access the wired network and communicate with each other. When Intra-BSS traffic
blocking is enabled, WiFi station A and B can still access the wired network but cannot communicate
with each other.

7.11.6 MBSSID

Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the
cost of buying extra APs, there is also the possibility of channel interference. The WX Device's MBSSID
