But when we talk about the handsets, undoubtedly, Nokia is the King of mobile phone market and LG stood at the third position. In this article we are concentrating on Nokia E5 from the house of Nokia and LG GM360 Viewty Snap by LG Mobile Com The Nokia Mobile Company is the undisputed leader in mobile world, they have latest technology and capability to deliver world class handsets at no extra costs. The N series, E series and C series phones have already rocked the world with th
In 1946, the first mobile phone was used by the Swedishpolice. The innovation was linked to the network of telephone and it wastypical of a two way technology of radio. This phone is not convenient where itwas able to make about 6 calls only before the battery was off. In 1947, Ring from the Bell Labs created the innovation ofmodern phones was by the hexagonal cells for the phones then later another fromthe lab visualized cell towers where it receive and transmit signals in about 3antenna directions compared to the 2 antenna directions. Moreover, even thoughseveral technologies are being enhanced, developments of electronics would takeso many years to make it matured and developed. In 1967, technology of mobile phones was already availablebut the users and consumers have to stay on a cell area. These cell areas thatare services using a station of base are not hand off phone calls in a base tothe other basis. While one is having a call transaction you can no longer tocontinue it after reaching a particular range. A. E. Joel, an engineer at the Bell labs, enhanced thehandoff call system in the year 1967. Handoff call system provides thecontinuity of the calls from a place to the other without having dropped calls. In 1971, the AT&T requested cellular service to the FCCwhile the innovation of technology had been enhanced. The approval took for about 10 years. FCC befound the Frequency band of 824 to 894 MHz into AMPS (Advanced Mobile PhoneService). For about decades, technologies made for mobile phonesexisted in the market. These mobile phones were installed in cars due to theheavy and large requirement of battery. At around 1950's, the Mobile TelephoneSystem A (MTA) was developed by the Erikson but it weighed about eighty pound,then later on improved into a range of 20 pound and still it is inefficient fora practical device that most of the people use today. Throughout the decades, there have been many technologiesthat existed that made mobile phones available. Most of the time, these phoneswere installed in vehicles due to the large battery requirements. For instance,the MTA (Mobile Telephone System A) developed by Eriksson was available inSweden in 1950's. Unfortunately, it weighed over 80 pounds, later versionshowever weighed around the 20 pound range, still making it ineffective fortruly portable devices that are used today. The first generation of cellular phones was made in 1983.Motorola, called Motorola DynaTAC 8000X,was introduced to be the very first portable cell phones. The FCC approved itto use in the US. It took for about 15 years in the market having over ahundred million of dollars expense.
