GSM Technology


General Information

GSM is also known as Global System for Mobile Communications, or simply Global System for Mobile. A technology started development in 1985 by a French company formerly known as Groupe Sp├ęcial Mobile. It’s main competetor is CDMA, currently in use by Bell Mobility, Telus Mobility and Mobility Canada carriers.

Currently, only two main carriers in Canada are operating GSM networks. Microcell (Fido, Cityfone) and Rogers Wireless. Fido was the first carrier to start utilising this technology, followed by Rogers Wireless mainstream around 2001. Several companies in the United States have adopted GSM and it’s spreading fast among AT&T Wireless, T-Mobile.

GSM operates on 4 different frequencies worldwide. However, only two are which are used in Canada, which are GSM-850 and GSM-1900.GSM-850 and GSM-1900 which operate at 1.9Ghz.

GSM calls are either based on data or voice. Voice calls use audio codecs called half-rate, full-rate and enhanced full-rate. Data calls can turn the cell phone into a modem operating at 9600 bps. An extended GSM feature is high speed circuit switched data, allowing the phone to transmit upto around 40 kbps.

GPRS

GPRS or General Packet Radio Service is an extended service of GSM Network adding the ability to surf the Internet on your phone at slightly higher speeds. GPRS Internet surfing is comparable to dial-up Internet service in it’s speed, operating at around 4 to 5 Kilobytes per second.

Surfing the net on your mobile isn’t exactly cheap compared to residential Internet services. It is generally billed by how much data you transfer and it can get costly!

We would not recommend the consumer use GPRS technology in place of a desktop computer with an Internet connection. It’s just too expensive

Incomming Model of Honda

Premiering at the 2009 Tokyo Motor Show, the latest CR-Z concept provided a glimpse at Honda’s first sporty hybrid coupe, which will be formally unveiled in production form at Detroit’s North American International Auto Show in January 2010. The 2-seat CR-Z combines futuristic styling, driving enjoyment and the latest in Honda hybrid technology. As striking as the car’s sleek lines are, it’s the environmental performance under the hood that sets it apart. Due to hit the streets in the second half of 2010, the CR-Z is that place in the universe where sport and efficiency meet.
