3G in Bangladesh

We have been also hearing about 3G in Bangladesh for quite long time by some media sources and seminars on different times, still we are not very sure about its implementation.

3G:

International Telecommunications Union (ITU): IMT-2000 consists of six radio interfaces

W-CDMA also known as UMTS
CDMA2000
TD-CDMA / TD-SCDMA
UWC (often implemented with EDGE)
DECT

3G Considerations:

Speed
Minimum speed of 2 Mbit/s for stationary or walking users, and 348 kbit/s in a moving vehicle

Service
Converged fixed, mobile, voice, data, Internet and multimedia services. One of its key visions is to provide seamless global roaming, enabling users to move across borders while using the same number and handset

Flexibility
Providing a highly flexible system, capable of supporting a wide range of services and applications. The IMT-2000 standard accommodates five possible radio interfaces based on three different access technologies (FDMA, TDMA and CDMA)

Affordability
3G systems had to be affordable, in order to encourage their adoption by consumers and operators

Compatibility
3G has to be compatible with existing systems. 2G systems, such as the GSM standard

Design
3G must be easily expandable in order to allow for growth in users, coverage areas, and new services, with minimum initial investment

We already have CDMA2000 in the country, Citycell and other PSTN operators are providing mobile broadband services by CDMA2000 technology. For recent few years our mobile phones has also has got the technology of supporting 3G technology, however we are still stuck at the fact of creating guidelines/ policies etc.

When will we actually get this service?
