WI-FI hotspots first proposed by Brett Stewart at the NetWorld conference in San Francisco Moscone Center in August 1993 First called Public Accessible Wireless LANs Term “Hotspot” introduced by Nokia in 1998
4
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 WI-FI products are widely available on the market
5
The range of the Wi-Fi depends on several factors Power output of wireless router Strength of the receiving wireless card Obstructions
6
Responsible for services rendered by the customer. Order of service User getting a bill for service Post-use satisfaction survey
7
Overview of Hotspots Free hotspots Provide open access User has to go authentication Open hotspots Wireless LANs that allow users to connect to get broadband access
8
Most remote netowrk and data management services are enabled by NOC Tracking Problems and Performance Driving Problem Resolution Performing Software and Firmware Updates Monitoring and Managing Servers Enhancing Network Security
9
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
10
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
11
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
12
Subscription Plan Pay-Go plan PrePaid Cards
13
Monitor network hardware and software components Routers Switches Aps Firewalls Authentication Servers 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
14
Configuration of User Accounts Techinical Support Account Management Usage History Historical and online usage monitoring
15
Operations Support System enables Wi-Fi service providers to introduce custom service offering Supporting various authentication choices Billing models Payment mechanisms Charging principles
16
Operations Support System can be equipped with ability to have session intercept pages Emergency Situations HotLining feature will provide an operator with the capability to address issues with users A wireless operator using the hotlining feature may hotline the user to resolve the problem. Blocking normal packet data usage Notify subscriber that packet data usage is blocked Directing subscriber to rectify blockage Restoring normal operations
17
Data Privacy A private connection is established. Over the public channel by using data encryption. Authentication Authentication is provided between communicating parties by the use of standard key encryption Reliability Data can not be tampered during a session.
18
VoIP Voice communication over the internet Mobile Hotspots Trains, buses, and ferries
