What is 4G? and how does 4G differ from 3G?

[cream.b]

what was the real difference between 3G and 4G. there is a lot of jargon and, as of december 6th, the formal definition is a moving target but there are two potential answers, one focused on technology and one based on ITU definitions.

what do u guys say?

Si kuhizi watu ukisema 3G tuna refer kwenye Teknolojia ya simu lakini nakumbuka kwenye topic za kwanza chuo kuhusu history ya computer tulifundundishwa mambo ya Generations. Kwa hiyo kuna 3G computer na 3G mobile

1st Generation 1940-1956 :Vaccum tubes
2nd Generation - 1956-1963: Transistors

3rd Generation - 1964-1971: Integrated Circuits
4th Generation - 1971-Present: Microprocessors

Tukija kwenye Mobile Generation ziko hivi

0G
0G refers to pre-cellphone mobile telephony technology, such as radio telephones that some had in cars before the advent of cellphones. Date back 1971

1G
1G (or 1-G) is short for first-generation wireless telephone technology, cellphones. These are the analog cellphone standards that were introduced in the 80's and continued until being replaced by 2G digital cellphones.

2G
2G (or 2-G) is short for second-generation wireless telephone technology. It cannot normally transfer data, such as email or software, other than the digital voice call itself, and other basic ancillary data such as time and date. Nevertheless, SMS messaging is also available as a form of data transmission for some standards.

3G Standards
3G technologies are an answer to the International Telecommunications Union's IMT-2000 specification. Originally, 3G was supposed to be a single, unified, worldwide standard, but in practice, the 3G world has been split into three camps.( UMTS CDMA and...... )

3G system must allow simultaneous use of speech and data services, and provide peak data rates of at least 200 kbit/s according to the IMT-2000 specification

4G
4G (or 4-G) is short for fourth-generation the successor of 3G and is a wireless access technology. It describes two different but overlapping ideas.

High-speed mobile wireless access with a very high data transmission speed, of the same order of magnitude as a local area network connection (10 Mbits/s and up). It has been used to describe wireless LAN technologies like Wi-Fi, as well as other potential successors of the current 3G mobile telephone standards.

Thanks for interesting topic

i agree with in some cases but lets look at system technology we have multiplexing and multiple access.he we talking about things like CDMA,OFDMA or OFDM which are used in LTE performance.

What is LTE i dont have much indepth knowledge in Mobile communication nilisoma subject yake mwaka 1ja tu na sikufanya vizuri. teh teh teh

Thanks for interesting topic

mkuu bigup kwa sana yani nilitaka kukupa kama thanks 100 hivi ila nimejikuta natakiwa moja tu
