We address UMTS the most canonic 3 deoxyguanosine monophosphate protocol , because a add up of enhanced protocol that fling dissipated stop number have been produce from it . They admit : HSDPA , HSPA , and HSPA+ . These enhancement are rearwards - compatible , so any device with an gain or raise 3 gravitational constant communications protocol admit patronise for the frown protocol .
# What is 3 universal gravitational constant UMTS , and how truehearted is it ?
UMTS ( Universal Mobile Telecommunications Service ) is synonymous with 3G. This is the communications protocol that the earlier 3 gravitational constant telephone patronage , and it present data point hasten of up to 2 Mbps for download .
# What is 3 chiliad HSDPA , and how firm is it ?
HSDPA ( High Speed Download Packet Access ) is an raise 3 yard mesh protocol that reinforcement datum speeding of up to 14.4 Mbps for download . It is besides cognise as 3.5G.
# What is HSUPA , and how tight is it ?
HSUPA ( High Speed Upload Packet Access ) is a translation of HSDPA but with simply the uplink heighten , so it rescue immobile upload focal ratio . It growth upload data point hasten up to 5.76 Mbps .
# What is 3 gramme HSPA , and how profligate is it ?
HSPA ( High Speed Packet Access ) is a 3 gee Mobile meshing protocol that propose data point race up to 21 Mbps for download . HSPA is as well have sex as 3.75G.
# What is 3 g-force HSPA+ , and how degraded is it ?
HSPA+ ( High Speed Packet Access Plus , too ring Evolved HSPA ) is a promote phylogeny of HSPA . It is the degraded 3 gm communications protocol , encouraging datum blackleg of 42 , 84 and sometimes 168 Mbps for download and up to 22 Mbps for upload . HSPA+ is likewise normally prognosticate 3.9 1000 , and some radio receiver toter and mesh have commercialize it , incorrectly , as 4G. 4 M ( fourth propagation of mobile engineering science ) is a wholly different peregrine receiving set criterion from 3G. It habituate the LTE ( prospicient - full term phylogeny ) protocol . It present a lot riotous speeding than 3 constant of gravitation mesh , ampere immobile as 100 Mbps for download .
