Personally I have been very privileged to have been in a situation where I was teaching some guys who just started using the android phones mostly the tecno android smartphone users who have readily got thousand and one questions to ask about the smart phone features including the difference between the different network signal (GPRS, EDGE and 3G) that interchanges periodically in their network notification area which actually led to creating the short enlightening post.
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.
Introduction of 3G network made video calling and seamless streaming of video possible, with download speed of up to 3.1Mbps.
UMTS is the same thing as 3G network in both download and upload speed. The acronym itself stands for Universal Mobile Telecommunication Service and allows a download/upload speed of between 384Kbps to 2Mbps.
Note that for Code-Division Multiple Access (CDMA) technologies, the 3G network is refereed to as Evolution Data Optimized (EvDO) which offers similar max upload speed as UMTS for GSM data communications.
HSPA (High-Speed Packet Access)
It is based on the 3G network and an enhancement to 3G. Thus has a faster upload and download speed. It’s maximum speed can scale as high as 14Mbps. HSPA is sometimes called 3.5G.
It is also important to note that both HSDPA and HSUPA belongs to the HSPA family. While HSDPA stands for High-Speed Down-link Packet Access, HSUPA means High-Speed Up-link Packet Access.
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.
4G LTE (Long Term Evolution)
LTE is a 4G communication standard that supports HD video streaming, download speed as high as 299.6Mbps.
These are the most recent mobile data communication technologies that makes both uploads and downloads faster than ever. You can get as much as 1GB/s with this generation of data technologies. While LTE-A stands for Long Term Evolution Advanced, WiMAX means Worldwide Interoperability for Microwave Access.
GPRS (114Kbps) < EGDE (368Kbps) < 3G(3.1Mbps) < HSPA (14Mbps) < HSPA+(168Mbps) < 4G/LTE/WiMAX( above 500Mbps)
*Packet-based means that data is broken into packets before being transmitted.
