CDMA2000 is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. It is a backwards-compatible successor to second-generation cdmaOne (IS-95) set of standards and used especially in North America and South Korea, China, Japan, Australia and New Zealand. It was standardized ...
Voice over LTE. VoLTE calling. Voice over Long-Term Evolution (acronym VoLTE) is an LTE high-speed wireless communication standard for voice calls and SMS using mobile phones and data terminals. [1][2] VoLTE has up to three times more voi [3] ce and data capacity than older 3G UMTS and up to six times more than 2G GSM.
LTE Advanced (LTE+, LTE-A; [1] on Samsung Galaxy and Xiaomi phones — 4G+) is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation ...
Access Point Name. APN settings connect the device to the internet via mobile carrier’s cellular network. These settings include IP addresses, gateways, and other technical details that enable the device to access the internet and send MMS. Typically, APN settings are configured automatically when SIM is inserted or eSIM is activated. [1]
GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM. Time-division multiple access (TDMA) provides multiuser access by chopping up the channel into sequential time slices. Each user of the channel takes turns to transmit and receive signals.
List of UWB-enabled mobile devices. Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The following is a list of devices that support the technology from various UWB silicon ...
Mobile telecommunications. v. t. e. 4G[1] is the fourth generation of broadband cellular network technology, succeeding 3G and preceding 5G. A 4G system must provide capabilities defined by the International Telecommunication Union (ITU) in IMT Advanced. Potential and current applications include amended mobile web access, IP telephony, gaming ...
Public warning alerts using embedded Cell Broadcast feature on Android 12. Cell Broadcast (CB) is a method of sending short messages to multiple mobile telephone users in a defined area at the same time. It is defined by the ETSI 's GSM committee and 3GPP and is part of the 2G, 3G, 4G LTE (telecommunication) and 5G standards. [1]
