WiFi Connections Several types: 802.11, 802.11b, 802.11a, 802.11g, 802.11n 802.11: max 2 Mbps, no longer produced 802.11b: 11 Mbps, cheapest, good signal range but slowest max speed of modern WiFi 802.11a: 54 Mbps, little interference, highest cost and short range and walls obstruct 802.11g: 54 Mbps, longer range, passes through walls, average price, interference 802.11n: 100 Mbps>, most range and least interference, not yet finalized, higher price, interferes with b/g networks (experimental)802.11ac around 500Mbps, Expected to be widely used by 2015 (as long as the Mayans were wrong), AC chips were announced January 5th, 2012 http://compnetworking.about.com/od/wirelessfaqs/f/howfastis80211g.htm
3g connections • 3G is available in nearly every major city in the US. • Speeds range from 450kbps to 1400kbps as seen below • To access 3G you must have a 3G capable device and a data plan • 3G is not too bad price wise, but overages can cost thousands • Can be used to access internet, make calls (video and voice), and download/upload data.

4g connections • The Newest mobile connection available to the public • Can reach speeds of 100mbps download and 50mbps upload (under ideal circumstances) • 4G works by using orthogonal frequency-division multiplexing or OFDM • OFDM: Signal is divided in to parallel data streams and then brought back together once it reaches your device • Under real world conditions, testers got 6mbps download on 4G and 1mbps on 3g • 4g isn’t available everywhere (see next slide)
