Differences Between Gprs, Edge, 3g, Hsdpa, Hspa+ WCDMA And 4g Lte

While conversing with a friend I was asked the
differences between GPRS, EDGE and 3G, decided to share my little
knowledge about the topic in case you might be confused about it too.

Before
advancing, it should be known that 1G, 2G, 3G, 4G, 5G etc refers to the
different generations of wireless communication technology
characterized by having a defined range of speed.

GPRS(General Packet Radio Service)
GPRS
is a packet-based* wireless communication service. It is a 2G
technology network that support a download speed of up to 114Kbps.
Limitation of GPRS is that GPRS data cannot be sent while a voice call is in progress.

EDGE(Enhanced Data GSM Evolution)
GPRS
and EDGE are both 2G technology but EDGE is significantly faster with a
download speed of up to 384Kbps. EDGE is sometimes called a 2.5G
network as it also has some characteristics of a 3G network but it
doesn’t satisfy the specification.

3G
Introduction of 3G network made video calling and seamless streaming of video possible, with download speed of up to 3.1Mbps.

HSDPA(High-Speed Down-link Packet Access)
It
is based on the 3G network and an enhancement to 3G. Thus has a faster
speed, download speed can be up to 14Mbps. HSDPA is sometimes called
3.5G.

HSPA+(Evolved High-Speed Packet Access)
HSPA+ is an evolution HSPA(HSDPA&HSUPA). It is a 4G technology that allows download at a rate of up to 168Mbps.

WCDMA is called “Wideband Code Division Multiple Access”. It’s a standard found in 3G networks.
4G LTE(Long Term Evolution)

LTE is a 4G communication standard that supports HD video streaming, download speed as high as 299.6Mbps.

Summary
GPRS(114Kbps) < EGDE(368Kbps) < 3G(3.1Mbps) < HSDPA(14Mbps) < HSPA+(168Mbps) < 4G/LTE(299.6Mbps)

*Packet-based means data is broken into packets before being transmitted.
