  2. General Packet Radio Service - Wikipedia

    en.wikipedia.org/wiki/General_Packet_Radio_Service

    GSM module or GPRS modules are similar to modems, but there's one difference: the modem is an external piece of equipment, whereas the GSM module or GPRS module can be integrated within an electrical or electronic equipment. It is an embedded piece of hardware. A GSM mobile, on the other hand, is a complete embedded system in itself.

    This makes HSCSD relatively expensive in many GSM networks and is one of the reasons that packet-switched General Packet Radio Service (GPRS), which typically has lower pricing (based on amount of data transferred rather than the duration of the connection), has become more common than HSCSD.

    en.wikipedia.org/wiki/GPRS_core_network

    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).

    en.wikipedia.org/wiki/GPRS_Tunnelling_Protocol

    GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points.

    The Directive also suggested that the "application of the new satellite positioning (GNSS) and mobile communications (GSM/GPRS) technologies to electronic toll systems may serve to meet the requirements of the new road-charging policies planned at Community and Member State level."

  8. LTE-M - Wikipedia

    en.wikipedia.org/wiki/LTE-M

    LTE-M or LTE-MTC ("Long-Term Evolution Machine Type Communication") is a type of low-power wide-area network radio communication technology standard developed by 3GPP for machine-to-machine and Internet of Things (IoT) applications.

  9. Conductive charging - Wikipedia

    en.wikipedia.org/wiki/Conductive_charging

    The technology is sometimes called "conductive wireless charging". [1] The need for a conductor-to-conductor connection between the power supply and the device is the main difference from inductive charging and other forms of wireless charging. The conductive power supply, often a charging base or pad, detects when a compatible receiver or ...
