3G Issues
What is 3G? Does India need it?
The GSM and CDMA networks are classed as second generation while the defunct analogue network was the first of the mobile network generations.
3G, or third generation, is the generic term used for the next generation of mobile communications systems. The new systems will enhance the services available today and offer multimedia and internet access and the ability to view video footage.
With a 3G phone and access to the 3G network you can send and receive video calls, watch live TV, access the internet, receive emails and download music tracks, as well as the usual voice call and messaging services found on a mobile phone.
Technically, the main difference between 3G and 2G networks is how quickly data can be sent and received. 3G networks can send data up to 40 times the rates of earlier digital networks, which means that in addition to audio, graphics and text, 3G customers can also send and receive video content, in 3G coverage areas. They provide service at 5-10 Mb per second.
3G was introduced in the United States early in 2002. By late 2004, it was finally providing transmission speeds sufficient to handle full-motion video, albeit over short periods of time (15 seconds to three minutes, in most cases). The third generation technology used in the UK is called UMTS. These services operate at 2100 MHz. (2.1GHz).
What does allocation of spectrum for telcos really mean?
These days you read a lot about telcos having a war with the Government about allocation of spectrum. So what does it actually mean?
Spectrum is airwaves which carry sound on a given frequency or band. It is scarce because there is limited bandwidth and a major chunk of airwaves is controlled by defence forces in India. There is only a finite spectrum and it is limited - cannot be created. (just like real-estate, which is a limited commodity and is not being created).
You cannot use 2G phones on 3G spectrum. 2G phones will continue to operate on...
