The main differences between a mobile phone and a computer are these. One is that obviously computers are bigger, run faster, easier to use and have a lot of more protocols and programs and features. Also, on a computer you can send pictures for free, and faster, when on a phone, MMS messages cost each time. Also, phones can get hacked easier through things like super bluetooth, which is where if someone has  super bluetooth they can access your secret files and do whatever they want with them like put them on their phone or delete them. Only, laptops get viruses a lot easier and phones hardly get them. Also, there are programs which protect your laptop from viruses. Mobile phones can also get Anti-Virus protection, but you are much less likely to catch one on your mobile.A wireless router's antenna technology generally determines its Wi-Fi signal strength and hence its range. Generally speaking, 802.11 wireless routers offer better Wi-Fi range than comparable 802.11b units due to improved antennas. In general, wireless routers currently offering the best Wi-Fi signal range, however, are 802.11n (sometimes called "wireless N") units. Where standard 802.11b and 802.11g routers contain just one Wi-Fi radio and antenna, wireless N routers contain two or three radios specifically designed to maximize Wi-Fi range. SMS range and coverage is different. Unlike WiFi, you cant send mail or call people all over the world for free, with SMS it costs more than double the service providers standard network rate, which can be quite annoying at most times.
