and device B supports WPA-PSK and WPA2-PSK. Therefore, you should set up
WPA-PSK
in the wireless network.
NOTE
It is recommended that wireless networks use
WPA-PSK
or
WPA2-PSK
encryption. The other types of
encryption are better than none at all, but it is still possible for unauthorized wireless devices to figure
out the original information pretty quickly.
When you select
WPA2-PSK
in your LTE Device, you can also select an option (
WPA
compatible
) to support WPA-PSK as well. In this case, if some of the devices support WPA-
PSK and some support WPA2-PSK, you should set up
WPA2-PSK
and select the
WPA
compatible
option in the LTE Device.
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every device in the wireless network must have
the same key.
5.5.2 Signal Problems
Because wireless 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.
5.5.3 BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or
between a wireless station and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS traffic
blocking is disabled, wireless station A and B can access the wired network and communicate
with each other. When Intra-BSS traffic blocking is enabled, wireless station A and B can still
access the wired network but cannot communicate with each other.
