Cellular Network and Smartphone Application Security Research Paper

Cellular Network and Smart promise Application Security - query Paper ExampleNumerous applications present in smart phones have raised new bail questions. Security is a prime requirement for users today and therefore users should be knowledgeable about their exposure to attacks. Types of Cellular Networks 2G Stands for second generation wireless telephone technology its known as personal Communications Service, or PCS, in the United States. 2G technologies can be broadly divided intoTDMA-based, FDMA-based andCDMA-based standards. Comp ard to previous 1G networks that were analogue, 2G offered digital encryption and started the data service for cell phones including text messages. Digital signals allowed effective data compression and multiplexing dapple reducing the emission of radio receiver power. Enhanced security decreased the incidences of frauds. 2G is also a cell phone network protocol .Their features included voice mail, caller ID, Conference calling and simple web applic ations wish web browsing and email. Some modifications in 2G led to the evolution of 2.5G and 2.75G that account for the transition to 3G. 2.5G has a electric circuit switch domain and included MMS technology along with GPRS. 2.75G technology enables improved data transmission evaluate by virtue of being an extension on top of standard GSM hence performed better than its predecessors 2G and 2.5G. 3G tierce generation succeeded the GSM standards. It provided great speed to browse through WebPages, play 3D games, download or flowing full motion music videos. Verizon Wireless was the first to introduce 3G services in 2005.3G was accompanied by increase bandwidth, and greater domiciliate for diverse applications by the inclusion of packet-switched data with spectral efficiency at greater speeds. There are two 3G families 3GPP and 3GPP2. 3GPP was formed to foster deployment of 3G networks that came from GSM. Deployment GPRS and EDGE began in 2000 and 2003 respectively. These techno logies are outlined by IMT-2000.IMT2000 stands for International mobile telecommunications while 2000 means it was launched in 2000 had data rates of 2000 Kbp and frequency range of 2000 MHz. 3GPP2 was introduced to help operators using CDMA2000 to move to 3G. 3.5G was introduced with cable speeds and its added features include faster browsing of graphic intensive put and on demand videos. 4G Fourth generation refers to fourth-generation wireless that overtakes the 3G technology. What really constitutes 4G is not yet defined further 4G networks are distinguished by their use of orthogonal frequency-division multiplexing (OFDM) rather than (TDMA) or (CDMA) even though carriers are divided on whether to use (LTE) or WiMAX. ITU standards claim that 4G network should allow exchange of data at 100 Mbit/sec whereas 3Gs speeds can be as low as 3.84 Mbit/sec. As pass judgment 4G is faster than all previous generations. Technologies that enhance coverage like FemtocellandPicocellare bei ng developed to support 4G technology. LTE (Long-term-evolution) It uses additional spectrum and multiplexing enhancing speeds which are10 times faster than 3G.The lag time has also reduced delay increasing the reactivity of buffering. It is known for its high quality Voice-over-IP (VoIP).It is believed that songs can be downloaded within 4 seconds and photos uploaded in 6 seconds. roughly of the smart phones support 4G LTE and it is available in more than 175 cities. WiFi WiFi provides wireless connectivity. It uses 802.11 radio technologies providing a fast and secure
