As whown 5g protocol stack consists of owa layer, network layer, open transport layer and application layer. The gprs protocol stack enables the software within a gprs handset or mobile station to.

Its the framework, often provided by usb device manufacturers, or os developers, that enables other developers to focus on the meat of their implementation, rather than worrying about implementing lower levels of usb correctly. It describes architecture of gsm protocol layers viz. The mac sublayer handles the mapping between the logical and transport channels, linking the rlc to the physical layer. The bottom three software layers are relatively equivalent to the bottom three layers of the tcp ip protocol stack.

This blog is in response to a comment about how to create a layer stack in arcgis. Physical layer carries all information from the mac transport channels over the air interface. Gsm protocol stack can be explored by studying deep into gsm protocol layers at various network elements viz.
