The Qualcomm MSM Interface is a proprietary interface for interacting with Qualcomm baseband processors and is a replacement for the legacy cellular extensions of the Hayes command set. [1] With mobile chipsets, communication between the application processor and the baseband processor happens through shared memory. On PCs with data cards, QMI ...
For many components, only proprietary drivers are available [1] (open source phones usually seek components with open drivers. [citation needed]) If firmware is not updatable and does not have control over any other part of the phone, it might be considered equivalent to part of the hardware. However, these conditions do not hold for cellular ...

Cellular network standards and generation timeline. EDGE/EGPRS is implemented as a bolt-on enhancement for 2.5G GSM/GPRS networks, making it easier for existing GSM carriers to upgrade to it. EDGE is a superset to GPRS and can function on any network with GPRS deployed on it, provided the carrier implements the necessary upgrade.
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones. A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
The upload and download speeds that can be achieved in GPRS depend on a number of factors such as: the number of BTS TDMA time slots assigned by the operator; the channel encoding used. the maximum capability of the mobile device expressed as a GPRS multislot class
RF Drive testing is a method of measuring and assessing the coverage, capacity and Quality of Service (QoS) of a mobile radio network.. The technique consists of using a motor vehicle containing mobile radio network air interface measurement equipment that can detect and record a wide variety of the physical and virtual parameters of mobile cellular service in a given geographical area.
The PRL is built by an operator and is normally not accessible to the user. Many operators provide the ability for the user to download the latest PRL to their device by dialing an Over-the-air (OTA) feature code. In the United States, for Verizon / MetroPCS / US Cellular, this feature code is *228 (*ACT).
