4G is the fourth generation of cellular network technology, succeeding 3G and designed to support all-IP communications and broadband services, enabling a variety of data-intensive applications. [1] A 4G system must meet the performance requirements defined by the International Telecommunication Union in IMT Advanced. 4G supports a range of ...
IMT-Advanced is intended to accommodate the quality of service (QoS) and rate requirements set by further development of existing applications like mobile broadband access, Multimedia Messaging Service (MMS), video chat, mobile TV, but also new services like high-definition television (HDTV). 4G may allow roaming with wireless local area ...
The current 4G systems that are deployed widely are WIMAX and LTE. The two are pure packet based networks without traditional voice circuit capabilities. These networks provide voice services via VoIP or VoLTE. Some systems are designed for point-to-point line-of-sight communications, once two such nodes get too far apart they can no longer ...
2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages. 2G technologies enable the various mobile phone ...
Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...
The details of the process of paging vary somewhat from network to network, but normally we know a limited number of cells where the phone is located (this group of cells is called a Location Area in the GSM or UMTS system, or Routing Area if a data packet session is involved; in LTE, cells are grouped into Tracking Areas). Paging takes place ...
Yes, 2G speeds, after up to 14 GB 4G LTE data [575] Yes Yes, but unclear if tethering continues to function after 4G data is depleted [575] Yes, with Extras Pack: int'l calling, and roaming in Canada, the Dominican Republic, and Mexico only [577] Yes [100] Owned by TracFone Wireless. Acquired from T-Mobile.
[1] [2] [3] C-RAN is a centralized, cloud computing-based architecture for radio access networks that supports 2G, 3G, 4G, 5G and future wireless communication standards. Its name comes from the four 'C's in the main characteristics of C-RAN system, "Clean, Centralized processing, Collaborative radio, and a real-time Cloud Radio Access Network ...
