What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to 
communicate directly with each other. The ad-hoc wireless network will not communicate with any wired 
network. 
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with 
a wired network through a wireless access point.
What is roaming?
Roaming is the ability of a portable computer to communicate continuously while it and its user are moving freely 
throughout an area greater than that covered by a single access point. Before using the roaming function, the 
user must make sure that the workstation is set to the same channel number used by the access point of the 
dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each 
node and access point, for example, must always acknowledge receipt of each message. Each node must 
maintain contact with the wireless network even when not actually transmitting data. Achieving these functions 
simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a 
system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates 
such factors as signal strength and quality, as well as the message load currently being carried by each access 
point and the distance of each access point to the wired backbone. Based on that information, the node next 
selects the right access point and registers its address. Communications between end node and host computer 
can then be transmitted up and down the backbone.
As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in 
touch with the original access point or whether it should seek a new one. When a node no longer receives 
acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it 
then re-registers, and the communication process continues.
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM 
(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available 
worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in 
the hands of users around the globe.
