Key directions of roaming development

Same standard roaming(CDMA 450)

Inter-standard(GSM / 3G / LTE)

Same technology roaming

(CDMA 800/CDMA 1900)ROAMING

4

Same standard roaming

Positive sides:- Minimum costs- No specific subscriber

equipment is needed (maximum service coverage)

- Common interests in CDG project

Negative sides:- Limited number of operators,

working in the standard- Small coverage zone

Conclusions: The most simple direction for realization, though it has more of the image character for Russia

CDMA 450

Same technology roaming

Positive sides:- Large coverage territory

Negative sides:- CDMA operators

interest is necessary- Production of new

terminal equipment is needed

Conclusion: The direction involves high costs

CDMA 800 / 1900
