Cloud computing • Also, distributed/grid computing • Computing services are delivered over the Internet, on demand, from a remote location, rather than residing on one’s own desktop, laptop, mobile device, or even on an organization’s servers • Benefits • Rapid scalability and deployment capabilities • Decreased maintenance/upgrades • Improved economies of scale
Communications Infrastructure • Network • Telephone Modems [56.6 kbps] • Broadbands >200 • Digital Subscriber Line (256 Kbps to 6 Mbps) [20 to 1 contention ratio] • Cable Modems (1 – 6 Mbps) [50 to 1 contention ratio] • T1/ T2 lines [10-100 Mbps] • Network infrastructure • Wired or Wireless
Wired communications • Fiber to the Home (FTTH) • Delivery of communications over optical fiber • About 1.2% of homes have FTTH connections. • Dallas, Jackson (TN), Sacramento
Broadband over Power Line • Power Line Communications (PLC), Power Line Telecommunications (PLT) • Manassas, VA deployed the nation's first citywide BPL system recently • The National Association for Amateur Radio opposes the idea due to interference with radio waves
Wireless infrastructure • Licensed vs unlicensed frequency • Personal Area Networks (e.g.Bluetooth, Ultra Wide Band) • 2.4 Ghz; 720 kbps • Medium Range • Wi-Fi (Wireless Fidelity) • Range upto 300’; 2.4 GHz • IEEE 802.11 standard • Long Range • WiMax (Wireless Interoperability for Microwave Access) • Range upto 30 miles • IEEE 802.16 standard • Mesh Networks • Satellite

RFID • RFID tags: Active; Passive; Semi-passive • RFID receivers • Electronic product codes • Uses: • Supply Chain Management • Asset (Inventory) Management • Maintenance of materiel
RFID: Verichip HTTP://WWW.SPYCHIPS.COM
RFID Sensor Devices • RFID tags (with EPC) will become cheap enough to tag objects & persons • Alternative: Smart cards • Are RFID tags SPY CHIPS?
Location based service: GIS • Desktop GIS • Proprietary GIS software • Accessible to one person at a time • Developer = User • Steep learning curve • Web-GIS • Proprietary GIS software • Accessible over internet • Separation of developers and users • Flatter learning curve for users • Geospatial Web (Where 2.0?) • Tagging content and data with geographic metadata • Open access to GIS • GIS combined with Web 2.0 tools (mashups) • Multiple developers as well as users • Uses • Emergency management; Surveillance; Transit • Loopt; Google’s Latitude; Foursquare; Hot Potato; Whrrl; Gowalla
