It is a subset of General Packet Radio Service (GPRS) on the GSM network and improves upon it offering speeds close to 3G technology, hence the name 2.75G. EDGE is standardized by the 3GPP as part of the GSM family and as an upgrade to GPRS. EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United ...
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.
Centre for Telecommunication Research is a research-based institute at the Sri Lanka Technological Campus (SLTC) to carry out innovative, collaborative and industry-sponsored research works in wireless communications and networking. Research activities at the CTR, both fundamental and applied, mainly focus on technologies related to the ...
Originally a collaboration between Sri Lanka Telecom and Telstra, Mobitel has been wholly owned by SLT since November 2002. [8] In January 2004, the company launched its fully-fledged 2.5G GSM network that is EDGE/GPRS enabled and designed to operate on the dual-band.
In telecommunication, a public land mobile network (PLMN) is a combination of wireless communication services offered by a specific operator in a specific country. [1] [2] A PLMN typically consists of several cellular technologies like GSM/2G, UMTS/3G, LTE/4G, NR/5G, offered by a single operator within a given country, often referred to as a cellular network.
This SRI-for-SM message may be sent to an HLR in the same network as the SMSC, or via an interconnect to an HLR in a foreign PLMN, depending on which network the destination subscriber belongs to. The HLR performs a database lookup to retrieve the B-Party's current location, and returns it in an acknowledgement message to the SMSC's GMSC entity.
Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU , but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.
On May 6, 2011, Sri Lanka Telecom Mobitel successfully demonstrated 4G LTE for the first time in South Asia, achieving a data rate of 96 Mbit/s in Sri Lanka. [ 66 ] On May 7, 2011, Sri Lankan Mobile Operator Dialog Axiata PLC switched on the first pilot 4G LTE Network in South Asia with vendor partner Huawei and demonstrated a download data ...
