In Europe 1926, radio telephony was first used on the first-class passenger trains Also introduced on passenger airplanes for air traffic security Germans used radios in tanks during World War 2. In 1946 soviet engineers successfully tested their version of a radio mobile phone mounted inside a car. It had a range of 20 kilometres (12.5 miles).
In the early 1940s the first 2 way radios to be developed were called mobile rigs. These were used in taxis, police cars and ambulances. Ran on electricity from vehicle Used radio waves to communicate
In the early 1940s Motorola developed a backpacked two-way radio, the Walkie-Talkie. Only one radio transmits at a time Push to talk button Used dry cell batteries for power
I n 1951 large hand-held two- way radio for the US military was developed. This battery powered Handie-Talkie and was about the size of a man's forearm. Limitations such as line of sight Interference from structures and large objects. Repeaters needed for long distance
First commercially available mobile phone was the Motorola DynaTAC 8000x. It cost $3995 Motorola MicroTAC 9800X was available in 1989 and the first real hand held portable mobile phone. 10 character LCD.
First Clamshell (Flip) phone was the Motorola Star TAC it also had first ever display for numbers and was available in 1996 it cost $1000 This Nokia 5110 (1998) was the most successful model at the time and continued to sell well for sometime afterwards
The Nokia 7110 (1999) was one of the first slide phones and was made very popular due to the movie The Matrix Samsung SPH-M100 Uproar (1999) was the first phone to have MP-3 capabilities MP-3
Nokia 3210 (1999) was the first phone with T9 (predictive text). 150 Million were sold First commercial camera phone was the Sharp J-SH04 and was available in 2000
Ericsson T68 (2001) was one of the first mobile phones with a colour screen Nokia 7600 (2003), one of the world first 3G smart phones. It is still one of smallest phones ever made3G
Motorola Razor V3 (2004) set a new standard is design and is one the most successful selling phones ever. Nokia 7280 (2004) was also referred to as the Lipstick phone. This phone has no keypad and all processes are carried out by using a small dial.
HTC Universal (2005) was the first pocket PC made by HTC and had windows mobile installedwindows mobile Nokia N73 (2006) was a very popular smartphone and even 3 years after its release it is still used widelysmartphone
Apple iPhone (2007)auto-rotate sensor, a multi-touch sensor that allowed multiple inputs while ignoring minor touches. On release this phone was extremely popular. 8Gb – 32Gb versions are available. iPhone 3G developed in 2009
Blackberry Storm (2008) Designed to be a direct competitor to the iPhone 3G and other 3G smartphones
Palm Pre (2009) Touch sensitive screen. This phone is to challenge the Apple iPhone. This phone is the first to come with a touch stone charger (wireless charge) 8GB internal storage stone charger
Google Nexus One Manufacturer HTC (Designed and branded by Google) Type Slate smartphone Release date January 5, 2010 Introductory price $529 unlocked $179 with 2 year contract  Operating system Android 2.1 (Eclair) CPU 1 GHz Qualcomm QSD 8250 Snapdragon ARM Storage capacity Flash memory: 512 MB microSD (Class 2) slot: 4 GB included, expandable up to 32 GB
Difference between 1G and 2G, is that the radio signals that 1G networks use are analog, while 2G networks are digital. Although both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system, the voice itself during a call is encoded to digital signals in 2G whereas 1G is only modulated to higher frequency, typically 150 MHz and up.
3G - Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (up to 14.0 Mbit/s on the downlink and 5.8 Mbit/s on the uplink with HSPA+). Thus, 3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. BackBack
MP3 - MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a method of data compression. It is a common audio format for consumer audio storage, for the transfer and playback of music on digital audio players. back
Touch Stone charger – charging the Palm Pre using Touchstone wireless inductance charging system ($69.99). The Touchstone charger utilizes magnetic inductance, or electric current produced through a loop of wire in the presence of a magnetic field, to charge its internal battery wirelessly. backback
Windows mobile - Windows Mobile is a compact mobile operating system developed by Microsoft, and designed for use in smartphones and mobile devices. It is the 3rd most popular smartphone operating system for business use (after BlackBerry and iPhone). back
smartphone is a mobile phone offering advanced capabilities, often with PC-like functionality (PC- mobile handset convergence). There is no industry standard definition of a smartphone. For some, a smartphone is a phone that runs complete operating system software providing a standardized interface and platform for application developers. For others, a smartphone is simply a phone with advanced features like e-mail, Internet and e-book reader capabilities, and/or a built-in full keyboard or external USB keyboard and VGA connector. back back
