GPRS/3G versus wireless local area network: Feedback Written by: Jonathan Briggs February 12, 2006 [9614 views] A big hap thanks to everywhere 100 of you who completed the exercise on time. It appears that legion(predicate) of you spent more than my estimate of 2 hours comple canfulg it alone those who birth seem to feel it was worthwhile. You will not be asked to remember exact numbers (distances, prices, speeds etc) for different technologies but as a professional working in this area you should keep a feel for their different capabilities. That means being capable to select from the technologies for different business applications. Speeds of mobile technologies (from a invitee point of view) GSM Modem 9.6 14kb/s but truely 9.6kb/s overly wordy for web search GPRS 56 114kb/s but typically about 33kb/s similar to dial-up modem speeds for PCs, suitable for web browsing 3G 384kb/s but typically about 144kb/s less(prenominal) than typical ADSL broadband speeds for PCs but adequate for streaming melody and impression (under ideal conditions) 802.11b (WiFi) 11 Mb/s (11000kb/s) typically 4 Mb/s connection between nucleotide topographic point and hand make out/laptop 802.11g (WiFi) 56 Mb/s (56000kb/s) typically close to the same speeds as 802.11b 802.

16 (WiMax) 70 Mb/s (70000kb/s) over frequently wider distances than WiFi Notice the difference between theoretical speeds and typical speeds. theory- backsided speeds operate only under laboratory conditions. In satisfying life the speeds will always be some(prenominal) sluggish because of interference, distance and obstacles. Also notice that WiFi speeds do not indicate the co nnection speed to the Internet which could b! e much slower. If I have a WiFi radio set connection in my home connected to a 512k ADSL connection, my ship speeds can never be faster than directly connecting to the ADSL with a cable. Distances from base-stations/cell towers Speed is only one part of the equation. To tin Cell or WiFi networks companies must provide base stations. Cellular mobile base stations may sieve an area of 1-2...If you want to get a full essay, pass off in it on our website: OrderEssay.net
