Mobile Application Part. The Mobile Application Part ( MAP) is an SS7 protocol that provides an application layer for the various nodes in GSM and UMTS mobile core networks and GPRS core networks to communicate with each other in order to provide services to users. The Mobile Application Part is the application-layer protocol used to access the ...
Mobile virtual network operators (MVNOs) in the United States lease wireless telephone and data service from the three major cellular carriers in the country, AT&T Mobility, T-Mobile US, and Verizon. [1] [2] In 2016, MVNOs across the nation such as Metro PCS, Boost Mobile, Cricket Wireless, and Tracfone brands served about 36 million subscribers.
High-Speed Uplink Packet Access ( HSUPA) is a 3G mobile telephony protocol in the HSPA family. It is specified and standardized in 3GPP Release 6 to improve the uplink data rate to 5.76 Mbit/s, extend capacity, and reduce latency. Together with additional improvements, this allows for new features such as Voice over Internet Protocol (VoIP ...
The Short Message Service is realised by the use of the Mobile Application Part (MAP) of the SS7 protocol, with Short Message protocol elements being transported across the network as fields within the MAP messages. [1] These MAP messages may be transported using "traditional" TDM based signalling, or over IP using SIGTRAN and an appropriate ...
The South Pole Telescope (SPT) is a 10-metre (390 in) diameter telescope located at the Amundsen–Scott South Pole Station, Antarctica.The telescope is designed for observations in the microwave, millimeter-wave, and submillimeter-wave regions of the electromagnetic spectrum, with the particular design goal of measuring the faint, diffuse emission from the cosmic microwave background (CMB).
