Finally, some good news from Dhaka. Four mobile operators have cooperatively started to swap frequencies to yield a more rational arrangement. Congratulations to the regulator, the industry body and the operators. After the rearrangement process, the quality of services of the mobile operators will be better than before with reduced call drops and more efficient network, said Abu Saeed Khan, secretary general of Association of Mobile Telecom Operators of Bangladesh (AMTOB). Explaining the matter, Khan said, if you have three pieces of land in different places, you will have to make more boundaries to separate your lands from others.
