A variant, so called Compact-EDGE, was developed for use in a portion of Digital AMPS network spectrum. [3] EDGE is part of ITU's 3G definition. [4] Evolved EDGE continues in release 7 of the 3GPP standard providing reduced latency and more than doubled performance e.g. to complement High-Speed Packet Access . Peak bit-rates of up to 1 Mbit/s ...
High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. HSDPA is also known as 3.5G and 3G+ . It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity.

GSM and related 2G and 2.5G standards, including GPRS and EDGE; UMTS and related 3G standards, including HSPA and HSPA+; LTE and related 4G standards, including LTE Advanced and LTE Advanced Pro; 5G NR and related 5G standards, including 5G-Advanced; An evolved IP Multimedia Subsystem (IMS) developed in an access independent manner
New HSDPA User Equipment categories 21-24 have been introduced that support DC-HSDPA. DC-HSDPA can support up to 42.2 Mbit/s, but unlike HSPA, it does not need to rely on MIMO transmission. The support of MIMO in combination with DC-HSDPA will allow operators deploying Release 7 MIMO to benefit from the DC-HSDPA functionality as defined in ...
General Packet Radio Service (GPRS), also called 2.5G, [a] is a mobile data standard on the 2G cellular communication network's global system for mobile communications (GSM). [1] Networks and mobile devices with GPRS started to roll out around the year 2001. [ 2 ]
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.
EDGE combined with the GPRS 2.5G technology is called EGPRS, and allows peak data rates in the order of 200 kbit/s, just like the original UMTS WCDMA versions and thus formally fulfill the IMT2000 requirements on 3G systems. However, in practice, EDGE is seldom marketed as a 3G system, but a 2.9G system. EDGE shows slightly better system ...
