2. What is a WI-FI hotspot? • Wireless Local Area Network location that provides broadband Internet access. • Use of laptops, PDA, or cellphones

3. 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
