You can use the digital camera on your cell phone to see if your TV remote control is working. Digital cameras are sensitive to infrared light, so if you point your TV remote control at your cell phone, its digital camera will pick up the infrared beam if the remote is working.

16. 8.2 Wireless Computer Networks and Internet Access Short range wireless networks Medium range wireless networks Wide area wireless networks

17. Short Range Wireless Networks 100 feet or less Bluetooth – text says a 30 foot (10 meter) distance but typically limited to 6 feet, 700Kbps Ultra-wideband – 100Mbps, good for streaming video Near-field Communications – a few centimeters, speed depends on device

24. Wireless Mesh Networks Use multiple Wi-Fi access points to create a wide-area network that can be very large. Mesh networks are essentially a series of interconnected local area networks.

25. Wide-Area Wireless Networks Cellular Radio 1st Generation (analog signals) 2nd Generation (digital, up to 10Kbps) 2.5 Generation (digital, up to 144Kbps) 3rd Generation (stationary – 2Mbps, but in a moving car – 128Kbps) 4 th Generation (stationary – 1Gbps, in a moving car – 100Mbps) Wireless Broadband or WiMax (31 miles, 75Mbps)

26. Cellular Radio Network The thing to note is that to get to a “land line” you must use a telephone company switch.

27. 8.3 Mobile Computing and Mobile Commerce Mobile computing - real-time, wireless connection between a mobile device and other computing environments, such as the Internet and an intranet Mobility Broad reach © Såndor Kelemen/iStockphoto

28. Mobile Computing Five value-added attributes of mobile computing: Ubiquity (but mainly in well developed nations) Convenience Instant connectivity Personalization Localization of products and services based upon knowing the location of the user

29. Mobile Commerce The development of m-commerce is driven by the following factors: Widespread availability of mobile devices No need for a PC (current intelligent phones have the computer power of laptops 3 years ago) The “Cell phone culture” Declining prices (Moore’s Law) Bandwidth improvement (Moore’s Law)
