Using 700 MHz Band For LTE : A Future Case Study


Bangladesh is planning to implement 3G in the telecommunication sector and the state owned company is going to get the 3G license first.But we all know that the developed world is already experimenting with LTE (Long Term Evolution) and already has got successful result and is going to implement the LTE in their country soon.
The main advantage in LTE is the requirement of less number of BTS to cover a certain area.For example,if you need 20 BTS to cover a certain zone then in LTE this can be done only be 1 BTS.
Another advantage is high data speed.The successful transmission of LTE shows data can be downloaded with a speed of 1000 Mbps which is approximately 1 Gbps.
The LTE will operate in the frequency spectrum of 700 MHz and will have a large number of carrier.As the frequency range is less,it will need less transmission power and also the transmission loss will be less cause the frequency is not that high.
But the main issue is that Bangladesh is already using this frequency band for the purpose of broadcasting national tv channel BTV.Not only Bangladesh,most of the countries in the world use this band of frequency for the purpose of broadcasting their national TV Channel.Cause using this frequency a large area can be covered.
Now the problem is if the frequency band is already been used by BTV then how the LTE will be incorporated with the mobile network?
Yes,this is really a question.Now what will be the solution?Is there any solution?
Yes,there is a solution.We need to withdraw BTV from this band and need to use this for LTE.But the question is then how the BTV will run?
As Bangladesh has already planned to launch its first maiden satellite Bangabandhu-1,DTH should be introduced in the market then the TV will be available everywhere in the country including the remote areas.As DTH operates with Satellite.
Hope proper authority is thinking of it and planning accordingly.
Readers please let me know what is your opinion.

Sure Friend we can think for alternative.But im not pretty sure whether for 700 Mhz band we need to pay spectrum fee or not. I thank its free Band.if we can establish LTE network then it will be cost effective and will bring a new era for Wireless Communication in Bangladesh.But I don't think, our corrupted Government will take steps to establish LTE Network in bangladesh
