(i) 

Whether IMT 2000 band should be expanded to cover whole or part 

of 1710   1785 MHz band paired with 1805   1880 MHz? 

(ii) 

What should be the path for creating more spectrum for CDMA and 

GSM services viz., options (a) or (b), and  

(iii) 

Should the 450 MHz or any other band be utilised for CDMA growth 

path?.   

2.7 

CDMA and CorDECT 

Another issue over allocation that has been raised by stakeholders is the 

allocation of 1880   1900 MHz for Cellular Mobile services. As per the present 

allocations, this band has been designated for Micro cellular technologies. 

Operators have largely deployed TDD based indigenous CorDECT 

technology in this band. As this band is used in some countries for providing 

cellular mobile services, there has been demand by service providers to either 

allocate this band for cellular mobile services and relocate CorDECT, or 

permit sharing of this band with CorDECT.  

A reference to this issue was also made by TRAI in its recommendations on 

Accelerating Growth of Internet and Broadband Penetration.  Para 3.7.4.11 

mentions 

 Requirements of micro cellular WLL systems based on TDD access 

techniques, especially indigenously developed technologies, capable of 

coexistence with multiple operators   should be altered to remove the 

reference to WLL.  This should be done so that the link between fixed wireless 

and mobile wireless technologies, which remains because of former WLL 

regime, is corrected for current technologies and bands, and future ones.     

2.8   Contiguous spectrum allocation and guard bands 

Presently spot frequencies allocated to service providers are not necessarily 

contiguous and therefore require larger amounts of guard band resulting in 

inefficient usage of spectrum. If reorganisation of existing allocations is carried 

out to achieve as much of contiguous allocations as possible, then better 

efficiencies can be achieved. Also it would reduce the need for guard bands. 

However, the exercise of reorganisation is likely to be difficult and exhaustive. 

2.9   Issues for Consultation 

(i) 

Should the 450 MHz or any other band be utilised particularly to 

meet the spectrum requirement of service providers using CDMA 

technology? 

(ii) 

The consultation paper has discussed ITU method for assessment 

of spectrum requirement.  Based upon the methodology submit 

your requirement of spectrum for next 5 years.  While calculating 

the required spectrum, please give various assumptions and its 

basis.
