How It Works ü Electromagnetic Waves-Both mobile phones and their base station towers transmit and receive data information using electromagnetic waves. ü Base station- link mobile phones to the rest of the mobile and fixed phone network

Zero Generation Networks ü 0 G ü Mobile radio telephone systems that became available in the 1970 s ü Preceded modern cellular mobile technology. ü Usually transmitters mounted in cars or trucks

First Generation standard (1980's): ü 1 G mobile phone networks were the earliest cellular systems to be developed. ü Used an analogue signal for voice calls only.

Second Generation Standard(1990's) ü 2 G mobile networks was the first mobile phone system that used purely digital technology. ü Introduced data services for mobile devices starting with SMS text messages. ü New digital systems emit less radio power from the handsets.

ü Third Generation Standard (2001): Third Generation mobile telephone networks support much higher data transmission rates and offer increased capacity, which makes them suitable for high-speed data applications as well as for the traditional voice calls. ü 3 G systems are designed to process data, with voice signals being treated as any other form of data. ü Third Generation systems implement packetswitching technology that is more efficient and faster than the traditional circuit-switched systems,

Third Generation Standard (Continued) ü 3 G phones provided: • • Internet access Multimedia applications, TV streaming, Multimedia, Videoconferencing, E-mail, Navigational maps.

Fourth Generation Standard (2010): ü Fastest wireless mobile network that today’s smart phones use. ü Coverage cities. is still limited outside some major ü 4 G networks provide connection speeds of about 3 to 5 Mbps -- as fast as wired DSL and cable; with a competitive price to current 3 G plans. http: //www. linkedandloaded. com/2011/06/12/from -1 g-to-4 g-cell-phones-making-moves/

3 G & 4 G Security Dilemma ü Hardware aspect üSmart phones mimicking personal computers. üTablets with built in 3 G & 4 G modems üNetbook with built in 3 G & 4 G modems ü Software aspect üOpen source vs. closed source http: //www. pcworld. com/article/248844/hacker s_ride_radio_waves_to_hack_smartphones.

Attack Methods ü Ransomware - an infection that takes control of a system until a ransom payment has been delivered ü Worms - poisoned SMS messages containing links to rogue applications, or through infected links on social networks such as Facebook and Twitter. ü Polymorphic malware – applications that infect your device & are extremely difficult to detect & destroy

Methods of defense ü Downloading smart phone antivirus software ü Be wary of suspicious SMS links & email ü Don’t download apps from un-trusted sources

Future of Mobile Technology �Faster speeds in smaller devices �Internet speeds & tethering options that rival desktop browsing speeds �Advanced pc connectivity & possible replacement.
