General Packet
Radio Service
|
General Packet Radio Service (GPRS) is a Mobile Data Service available to users of Global System for Mobile Communications (GSM) and IS-136 mobile phones. GPRS data transfer is typically charged per megabyte of transferred data, while data communication via traditional circuit switching is billed per minute of connection time, independent of whether the user has actually transferred data or has been in an idle state. GPRS can be used for services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web
access.2G cellular systems combined with GPRS is often described as "2.5G", that is, a technology between the second (2G) and third (3G) generations of mobile telephony. It provides moderate speed data transfer, by using unused Time division multiple access (TDMA) channels in, for example, the GSM system. Originally there was some thought to extend GPRS to cover other standards, but instead those networks are being converted to use the GSM standard, so that GSM is the only kind of network where GPRS is in use. GPRS is integrated into GSM Release 97 and newer releases. It was originally standardized by European Telecommunications Standards Institute (ETSI), but now by the 3rd Generation Partnership Project

BMW
series 7 The BMW 7 Series is a line of full-size luxury vehicles produced by the German automaker BMW. It replaced the "New Six" models in 1977. It is BMW's flagship car and is only available as a
sedan..
it's the BMW flagship, and this full-size, rear-wheel-drive
sedan has always represented the pinnacle of technology and luxury
accoutrements in the German automaker's lineup. As such, it's an
obvious choice for wealthy car buyers seeking a spacious and
elegant sedan with a high level of curbside prestige.There's a
fair amount of competition even in this elite vehicle class, but
the 7 Series sedan's athletic handling dynamics have long set it
apart, starting with the early 733s and carrying through to the
present-day BMW 750i, 750Li and 760Li. While other manufacturers
have been content to build high-end sedans with soft, serene rides,
BMW engineers its 7s to engage their drivers on an emotional level.
For that reason, the BMW 7 Series is the definitive super luxury
sedan for people who like to drive.The boot is cavernous, so no heated discussions about the girls
leaving half their wardrobe behind. There would be plenty of room
for favourite toys just in case the weather turned nasty and you
could even stock up with provisionsto save wasting time at the
village store when you could be on the beach. Bliss.
Much has been written about BMWs novel i-Drive system, designed to
eliminate dashboard switchgear. Much of this has been negative,
mainly because those concerned dont seem to have bothered to read
the handbook. So lets get this straight: i-Drive makes sense.
After all, this car has so many functions that if you gave them
all a switch, the dashboard would look like the cockpit of a 747.
Besides, the current 7-Series features a less complicated version
of the system. Many of the more commonly used controls have been
relocated out of the computer and onto the dash.
Sit behind the wheel and the main i-Drive functions are controlled
by a circular silver wheel by your left hand. You push it towards
either of the eight positions of the compass to select all the
main function areas like the stereo system, the trip computer, the
satellite navigation system, the TV (where fitted) and so on.
Theres even a section that tells you just how much life is in all
the consumable parts of the car the brake pads and so on and when
youre going to need to replace them. Clever.You start the car with a push button and theres the option of
changing gears via an arrangement of silver buttons on the
steering wheel. Four petrol models are available , the 730i, the
740i, the magnificent 750i that I tried and a range-topping 760i.
Oh and a diesel 730d. Whichever version you choose, youll find
that the automatic gearbox is arguably the smoothest youll find,
either for stop start driving around town or long motorway
stretches.The Servotronic steering meanwhile, (ask the dealer all about it)
makes for easy handling. And if you care about these things, the
750is engine is good enough for sixty in 5.9 seconds on the way to
a top speed of 155mph which, like its boardroom brother, is
artificially limited. No wonder - the ride is so quietly
comfortable that you do have to keep an eye on the speedometer to
avoid any embarrassing attention from the law.
