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?
Mobile WiMAX is 4G not 3G. Also Mobile WiMAX can easily be deployed since Banglaion and Augure are already building the data network.
ReplyDeleteVoice-over-WiMAX would be a quicker option.
ReplyDeleteThere won't be any 3G this year ... So wait till 2010 atleast ...
ReplyDelete3G tecnology must be shoud give the goverment cause 2G work very slowly.
ReplyDeletejuwel,
ReplyDeleteedge currently being provided is 2.5g, it can serve speed like 230 kbps, however we don't get the speed because of mainly number of subscribers is more than the bandwidth being offered. mobile operator should purchase more bw to support users like us. also the quality of network is not good most of the time.

ReplyDeleteprobably your area or your device doesn't support the average or max speed that gp provides. as per most of the people who use mobile internet likes gp's internet service. whats your location and modem anyway?
