As the GPRS standard is an extension of GSM capabilities, the service operates on the 2G and 3G cellular communication GSM frequencies. [10] [12] GPRS devices can typically use (one or more) of the frequencies within one of the frequency bands the radio supports (850, 900, 1800, 1900 MHz). Depending on the device, location and intended use ...
GPRS Tunnelling Protocol is the defining IP-based protocol of the GPRS core network. Primarily it is the protocol which allows end users of a GSM or WCDMA network to move from place to place while continuing to connect to the Internet as if from one location at the Gateway GPRS support node (GGSN).
In GPRS Coding Schemes CS-1 through CS-3, the convolutional code is of rate 1/2, i.e. each input bit is converted into two coded bits. [5] In Coding Schemes CS-2 and CS-3, the output of the convolutional code is punctured to achieve the desired code rate. [5] In GPRS Coding Scheme CS-4, no convolutional coding is applied. [5]
WAP Push was specified on top of Wireless Datagram Protocol (WDP); as such, it can be delivered over any WDP-supported bearer, such as GPRS or SMS. [13] Most GSM networks have a wide range of modified processors, but GPRS activation from the network is not generally supported, so WAP Push messages have to be delivered on top of the SMS bearer.
Android, a mobile OS developed by Google, is the first completely open-source mobile OS, meaning that it is free to any cell phone mobile network. Since 2008 customizable OSs allow the user to download apps like games, GPS, utilities, and other tools. Users can also create their own apps and publish them, e.g. to Apple's App Store.
The 3rd Generation Partnership Project (3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications.Its best known work is the development and maintenance of: [1]
Jonas tripped on his shoelace, and his “head went full force straight into the locker room’s metal grated doors.” Because they were filming a prank video, “everyone laughed thinking this ...
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location.
