What is Edge: Definition and 264 Discussions

Enhanced Data rates for GSM Evolution (EDGE) (also known as Enhanced GPRS (EGPRS), IMT Single Carrier (IMT-SC), or Enhanced Data rates for Global Evolution) is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM. EDGE is considered a pre-3G radio technology and is part of ITU's 3G definition. EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United States.EDGE is standardized also by 3GPP as part of the GSM family. A variant, so called Compact-EDGE, was developed for use in a portion of Digital AMPS network spectrum.Through the introduction of sophisticated methods of coding and transmitting data, EDGE delivers higher bit-rates per radio channel, resulting in a threefold increase in capacity and performance compared with an ordinary GSM/GPRS connection.
EDGE can be used for any packet switched application, such as an Internet connection.
Evolved EDGE continues in Release 7 of the 3GPP standard providing reduced latency and more than doubled performance e.g. to complement High-Speed Packet Access (HSPA). Peak bit-rates of up to 1 Mbit/s and typical bit-rates of 400 kbit/s can be expected.

    How did the Big Bang get fixed?

    And what will we find there? Maybe us. What would be wrong with considering that we ARE on the edge of the universe! After all every where we look we can only see into the past where thinks get smaller and older the further away they are until reaches the very small BIG BANG space. The...

    Chain sliding off the edge of a table

    A uniform chain of length 8.00m initially lies stretched out on a horizontal table. a) If the coefficient of static friction between the chain and the table is 0.600, show that the chain will begin to slide off the table if at least 3.00m of it hangs over the edge of the table. b)...

    Europe's long term plans for cutting edge astronomy and cosmology research

    "Review of Cosmic Vision 2015-2025" begins: "The Cosmic Vision workshop at UNESCO on 15-16 September 2004 showed that Europe is richer than ever in ideas for what should be done in space science in the coming years. This workshop brought us a major step forward in developing the vision of the...

    What is the mysterious structure with lights in the fields on the edge of town?

    Does anyone know what would be in a field that would have a light on it, except its a structure and not a house, it had 3 lights on it in odd places.I couldn't tell what it was.I don't know much about farming or anything like that but the fields on the edge of my town are growing crops and...

    Is there a way of trisecting an angle using a compass, straight edge and pencil?

    I know that there is a way to bisect an angle using that equipment, but is there a way to trisect it. I have heard it is possible to do it by constructing a regular polygon with sides of a multiple of 3 around the angle. Does any1 have anything?

    What happens to light when it reaches the edge of the universe?

    What happens to light when it reaches the edge of the universe? it couldn't keep on traveling into nothingingness could it? becuase that nothingness would be space. it couldn't reflect off something unless there was matter at the edge to reflect off. the light must do something, it...

    Occam’s Razor has lost its edge

    First, we find in the skeptics dictionary that the concept is not well defined. http://skepdic.com/occam.html Next, the concept predates modern physics and is no more valid than 12th century physics. Consider Occam's original premise: Clearly the credibility of this premise died with...
