5.5.2 Problems with signal
Because wireless networks are WiFi radio networks, their signal is affected by distance and interference or
absorption signal.
Dropouts due to distance occurs when the devices are too far apart. The problems due to interference occurs
when a data signal disrupt other radio waves. Interference can come from other radio transmissions, such as
military communications systems, or air traffic control, but also on devices that are only random emitters, such
as electric or microwave oven. Absorption problems occur when the radio is between two physical barriers (eg.
Thick walls).
5.5.3 BSS
Basic Service Set (BSS) is a set of stations that can communicate with each other at the physical layer of
wireless connectivity through one access point (AP).
Independent BSS (IBSS) is a wireless transmission between stations in the basic service set. If the IBSS is
prohibited individual wireless stations can access the network and communicate with each other. If the IBSS is
enabled, wireless stations each can still access the network, but among themselves they can not
communicate.

5.5.4 MBSSID
To configure different basic service set (BSS) is typically necessary to use another access point (AP). In
addition to the cost of another access point also threatens their interference channels. Function MBSSID
(Multiple Basic Service Set IDentifier) of the LTE modem enables use of a single access point to provide
