  • TSM 241 Voice and Data Networking Cellular Communications Applications
  • Wireless Economics Since the first Cellphone, no wireless provider has turned a profit. In order to make money, the operators must provide attractive tariffed services The future of wireless economy hinges on unique wireless applications (unique in that the wireless technology makes them possible) Let's look at some emerging unique applications....
  • Applications for 3G IMT-2000 has specified at least ... Voice A variety of voice services Different capacities, different prices All at least as good as wired voice Messaging Services Variety of services - from simple paging to broadcast information subscriptions Wireless Web Specialized wireless web systems that allow high-speed browsing and other Internet capabilities
  • 3G Messaging
  • Messaging System Support
  • New Applications of Messaging
    • Voice Mail Notification
    • Reprogramming - like download new ring tones
    • Advertising - not spam, but new features and billing reminders
    • Broadcast Information Services. News, finance, sports, etc. Only problem, these are broadcast, not selective - if you subscribe to one, you get all.
    • Specialized Information Services. Particular events. This is the non-broadcast info. Such as a stock price reaching a threshold level, or plane flights being delayed. These are normally 'extra tariff' services.
    • Person-to-Person Messaging. Fastest growing area of messaging. Popular among school kids. Cheaper than voice.
  • The Wireless Web
    • Current Issues
      • Low Capacity: 9.6-14.4kbps
      • Small screens, and text only
  • The Wireless Web
    • HTML doesn't work. It is being replaced
      • C-HTML (compact)
      • HDML (Handheld Device ML)
      • XML (Extensible ML)
      • WML and WMLScript (wireless version of Javascript).
    • WAP (Wireless Application Protocol) used between Internet and wireless user. TCP/IP translated to/from WAP at a Gateway.
  • Where are the ‘Killer Apps’?
    • 3G 'expansions' are not enough
    • In order to turn a profit operators must determine how to derive additional income from content and services .
    • In order to sell a service or product, it must:
      • Entertain or
      • Reduce Costs or
      • Save Time or
      • Increase Profits
    • What are the new capabilities that can be utilized?
    • It’s all about Information
    • Location, Motion, Interaction, Co-relations
    • Combination of technologies: wireless and data-mining
    • Let's take a look at some of the innovative uses of wireless technology.
  • Automatic Vehicle Location (AVL) SOURCE: TRIMBLE NAVIGATION
    • Benefits of AVL
    • Fast dispatch
    • Customer service
    • Safety, security
    • Digital messaging
    • Dynamic route optimization
    • Driver compliance
    • Sample AVL Users
    • Chicago 911
    • Inkombank, Moscow
    • Taxi companies
  • GPS and Auto Insurance
    • Need to rate drivers accurately
      • age, residence and driving record not enough
      • driving after midnight is 10 TIMES as risky as at 8:00 a.m.
      • commuting is the safest kind of driving
      • parking in high-crime neighborhoods increases payout
    • Progressive Insurance (Mayfield, Ohio)
    • “ Autograph” policy: car is outfitted with GPS, cellular modem, microprocessor + 256KB memory
    • When ignition is turned on, car records location every six minutes
    • Once a month, uploaded to Progressive by cellphone
    • Customer is billed retrospectively every month
    • 25-50% savings in premiums
    • Increases Progressive’s share but also gives them the right share (safe drivers)
    GPS and Auto Insurance
  • Location-Aware Applications
    • Vehicle tracking
    • Firemen in buildings, vital signs, oxygen remaining
    • Asset tracking
    • Baggage
    • Shoppers assistance
    • Robots
    • Corporate visitors
  • Automatic Identification and Data Capture (AIDC) Problem: how to obtain data from physical objects Examples: product ID, price, serial number Bar code Two-dimensional Magnetic stripe card Smart card Radio Frequency Identification (RFID) Real-Time Locating Systems (RTLS) RFID CIRCUIT TAG WAND READER
  • AIDC Applications
    • Highway toll collection
    • Freight containers
    • Animal identification
    • Theft detection
    • Inventory, asset management
    • Traffic control
    • Gas station billing
  • Java Ring
    • Java-enabled i-Button
    • Communicates by contact at 142 Kbps
    • 64 KB ROM and 134 KB RAM
    • Stores 30 digital certificates with 1024-bit keys
    • Uses: authentication, e-payment, access
    • Cost: $15-30 in unit quantity
    iButton Link Thermocron Button Video
  • Bluetooth
    • A standard permitting wireless connection of:
      • Personal computers
      • Printers
      • Mobile phones
      • Hands-free headsets

      • Notebooks
      • Desktop PCs
      • PDAs
  • Bluetooth Characteristics
    • Operates in the 2.4 GHz Industrial-Scientific-Medical (ISM) (unlicensed) band. Packet switched. 1 milliwatt. Low cost.
    • 10m to 100m range
    • Uses Frequency Hop (FH) spread spectrum, which divides the frequency band into a number of hop channels. During connection, devices hop from one channel to another 1600 times per second
    • Bandwidth 1-2 megabits/second
    • Supports up to 8 devices in a piconet (two or more Bluetooth units sharing a channel).
    • Built-in security.
    • Non line-of-sight transmission through walls and briefcases.
    • Easy integration of TCP/IP for networking.
