First called Public Accessible Wireless LANs
Term “Hotspot” introduced by Nokia in 1998
WI-FI uses unlicensed radio spectrum and does not require regulatory approval for individual installation
Allows LANs to be deployed without cabling, reducing cost of network
Ideal in locations where running physical cables isn't practical such as outdoors or historical buildings

Authentication Identifies which entity can gain access to the
network Authorization
Identifies the boundaries or limits of the access provided to each user
Accounting Tracks the duration of the access and
accounts for the time used and data transferred during the session
Contracts that quantify the service given to a customer Bandwidth usage Service availability Latency Throughput Outage notification requirements An acceptable level of service provider
performance is guaranteed to the customer
Price plans offered to customers can be divided into units called packages
A price plan can comprise of many packages At least one package fee or one service rate Package fee will be a standard fee that has no
measurement unit Service rate will be measured with an activity
unit

Pinging utility used in polling the AP at regular intervals If AP outage occurs the network administrator is
notified by email. Faults in devices can be immediately detected,
isolated, and fixed
