What is Bluetooth?
Bluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The key features of Bluetooth technology are robustness, low power, and low cost.

Technically, Bluetooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Bluetooth" is borrowed from Harald Bluetooth, who was a king in Denmark more than 1,000 years ago (Computer people choose the strangest names!).  Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including cell phones, PDAs, and wireless headsets.

What is EDGE?
EDGE (Enhanced Data Rates for Global Evolution) is a radio signalling technology for 3G mobile networks. It boosts data transfer rates and volumes on existing GSM/GPRS networks by significantly increasing data transfer speeds.

How does EDGE work?
EDGE works by improving the signalling interface used to communicate over the radio waves. Typically, EDGE brings three times the performance of GPRS, achieving an average data rate of 80 to 160 kbps per user with mobile terminals supporting 2-4 timeslots. It is great for applications that transfer large amounts of data between a mobile phone and enterprise networks - such as rich email messages that include attachments.

About EDGE
Due to its high data transfer rates, EDGE has been adopted as part of ITU's (International Telecommunication Union) family of technologies. Currently, EDGE is standardized by the same 3GPP standardization body as the 3G technology, WCDMA, harmonizing the development of both EDGE and WCDMA.

Benefits of GSM & GPRS

• Faster connection
• Greater data volumes achieved
• Significant increase in functionality
• Can interoperate with with GSM networks for global coverage

What Is GSM?
Today's Wireless Revolution is being achieved through the GSM family of wireless technology platforms - today's GSM, GPRS, EDGE & 3GSM.  It is the basis of a powerful family of platforms for the future - providing a direct link into next generation solutions including GPRS (General Packet Radio Services) EDGE (Enhanced Data for GSM Evolution) and 3GSM.  GSM's unrivalled success can be attributed to many factors, including the unparalleled co-operation and support between all those supplying, running and exploiting the platform. It is based upon a true end-to-end solution, from infrastructure and services to handsets and billing systems.  GSM is a standard that embraces all areas of technology, resulting in global, seamless wireless services for all its customers. It's all part of the Wireless Evolution.

GSM (Global System for Mobile communications) is the technology that underpins most of the world's mobile phone networks. The GSM platform is a hugely successful wireless technology and an unprecedented story of global achievement and cooperation. GSM has become the world's fastest growing communications technology of all time and the leading global mobile standard, spanning 214 countries.  Today, GSM technology is in use by more than one in five of the world's population - by June 2006 there were over 2 billion GSM subscribers, representing approximately 80% of the world's cellular market. The growth of GSM continues unabated with almost 400 million new customers in the last 12 months.  The progress hasn't stopped there. Today's GSM platform is living, growing and evolving and already offers an expanded and feature-rich 'family' of voice and multimedia services.

Before You Buy, Please Note:
Most of our unlocked cellular phones are only designed to work on GSM networks, such as Cingular and T-Mobile (in the U.S.) and Fido and Rogers (in Canada).
