Ans 1:
The 'G' in 3G and 4G stands for 'Generation'. It means that 4G is a technology than 3G. The 3G service offers Voice, Messaging, Data services at High Speed while the 4G offers all these services where Data services are multiple times faster than the 3G services. The 3G technology is near dead in India due to --
--High Prices--
--The 3G Spectrums in India were sold on a higher than Global average prices to the Telcos, making it less economical for them.
--The taxes on among others Spectrum usage, license fee etc. are higher on India telecom operators compared to what is charged on their counterparts in the neighbouring countries.
--The Municipal authorities levy exorbitant charges for letting the Fibre Cables to be laid.
--All these make the '3G' prices higher due to 'Cost push' factor.
--Technology Related Issues--
--The high prices and low penetration of '3G' technology have resulted in the 3G services to become as slow as 2G services. The difference in the data is hardly recognizable by the consumers.
--The advent of 4G at the cost of 3G has made customers to switch to 4G, making 3G obsolete.
--The introduction of 'Smart' devices viz Mobile wifi 4G compatible routers, Wifi Hotspot, 4G dongles, Bluetooth 4.0 has made the consumers to move towards the 4G services.
----The 3G technology due to high acquisition and operational costs count not spread as much as expected in India and with the advent of 4G now, it seems to get forgotten in the next 5 years.
Ans2:
Difference s in 3 G and 4 G
1. High speed of at least 100 Mbites per second in 4G while 3G usually has speed of 200 kb per sec .
2. 4G requires new technology phones and new towers supporting 4G technology while 3 G covers most urban areas of india
3. 4G is basically 4 generation of technology while 3G is third generation technology.
4. 4G is particularly useful for watching videos , youtube and those who use lot of internet while 3 G is good for FB, Emails , Whatsapp , Weather, Google maps .
5. 4G is available only on new phones like iPhone 5 , Samsung galaxy 3 etc while 3 G is available on cheap phones too with 2G technology embed ed in it .
6. LTE (long term evolution) , Wimax and HSPA + are some deployments of 4 G which provide fastest speed .
Drawbacks of 3 G( as good as dead) while 4G and 3G are available at equal prices the shortcomings in 3G network are overcome in 4 G network which is in the initial stages of telecommunication revolution due to its high speed and cost effectiveness.
1.High power consumption your battery needs charging every other hour .
2. 3G is available only in urban setting and that too in variable and inconsistent speed .
3. 3G is available only in few and costly handsets .
4. Service providers .have to pay high prices for 3G licensing and infrastructure development.
Ans3:
The "G" stands for a generation of mobile technology in phones and cellular network. 3G stands for 3rd generation mobile technology used for wireless voice telephony,internet access,video calls with speed of 21 Mbps whereas 4G stands for fourth generation technology enabling high internet speeds 5 times faster than 3G with download speed upto 100 Mbps providing ultra broadband internet access to laptops with USB wireless modems,smartphones.Used in 3-D television,cloud computing,video conferencing,gaming.
Reasons behind failure of 3G in India:
1. Poor quality of 3G including both data speeds and connectivity.On the other hand 4G provides digital superhighway with uninterrupted services.
2. Unwillingness of telecom operators to invest in 3G due to high spectrum prices.
3. 4G technology and Wi-Fi services are more prominent attracting users to switch from 3G.
4. 3G is limited in reach and service standards,lack of good coverage in both urban and rural areas.
5.Government liberalised spectrum usage and thus telcos are free to offer any type of service on various bands.
6. Indian customers demands for high quality high speed data which 3G failed to deliever.
Still 3G services can be continued by those who cannot afford 4G technology based smartphone,where there is no such need of high speed internet access and is mostly for voice use, in areas facing network coverage problem,in cities where 4G network is unavailable.Technology is a continous evolving platform as per customer needs, working for betterment of services making customers choose options served in their plate as per their use.
