Common misunderstandings about EDGE

Common misunderstandings about EDGE:• GPRS and EDGE are two different technologies• EDGE uses a modulation that is very sensitive to poor radio conditions• EDGE and GPRS have almost the same throughput• EDGE needs more sites than GSM/GPRS due to worse coverage performance• EDGE requires major network upgrades• There is no need for EDGE in Europe where WCDMA is being deplo...

Classes of GPRS services

Classes of GPRS servicesMobile devices can request different types of traffic to be prioritised in an attempt to give the user their desired level of connectivity. There are 4 types of class:Precedence ClassAn application can be assigned a Precedence Class 1, 2 or 3. If an application has a higher precedence (1) than another (3) then its traffic will be given a higher priority.Delay ClassApplications...

GPRS Handset Classes

GPRS Handset ClassesGPRS devices are not as straightforward as you may think. There are in fact 3 different classes of device.Class AClass A terminals have 2 transceivers which allow them to send / receive data and voice at the same time. This class of device takes full advantage of GPRS and GSM. You can be taking a call and receiving data all at the same time.Class BClass B devices can send / receive...

Meaning of RxLev Full and RxLev Sub

“Full” and “Sub” ValuesInformation elements with “Full” in their names are calculated on all blocks.Information elements with “Sub” in their names are calculated only on the blocks known to be sent also when downlink DTX is active (in each 104-multiframe, one TCH block with SID information and one SACCH block).Similar to RxQual Full & RxQual ...
