Hello all;
It is nice to read the recommendations that PS-4 study made. Thank you
Gajendra ji for that. Please comment on my ideas if I am wrong.
There is no doubt that CDMA will cover a large area of Nepal and will
provide telephone and Internet servise to the people in the rural areas.
However, CDMA has bandwidth constraint and the 153 kbps Internet
connection is good for browsing only the Internet and send emails.
However, it is not enough for delivering telemedicine and teleteaching
requirements of the rural areas. Telemedicine and teleteaching are the
needs of the rural areas where no doctors and qualified teachers are
available.
My strong point is that wireless is the only way to bring the medical
doctors living and working in the city hospitals virtually to the
villages. There is no way anybody can force them to go and work in the
remote areas. If we find ways to connect them to the villages through
wireless, there will be many doctors available to serve the rural areas
people. The same is true with qualified teachers that are needed in the
rural schools.
Fiber optics is the best solution to provide the high bandwith
connectivity for telemedicine and teleteaching purpose. However, it will
not be practical in the Mahabharat and Himalayan region. VSAT is the
easiest solutions, but who can afford the US$3 per kbps bandwidth charge?
Therefore Wireless network is the best solution to meet the needs that
CDMA can't not provide.
Here is one idea. Nepal is about 1,400 km long from East to West. If we
build relay towers at about a distance of 30 km apart, we will need to
build about 45 relay towers. These towers should be built on the mountain
ranges right after the Terai belt from where it can cover maximum areas to
the North and to the South. From those towers, we need to build towers to
the North at about the same distance. The average distance from South to
North of Nepal is about 100 KM. That means we need to build three towers
to cover North to South. That will make about 150 towers in total.
Now NTC has already built many towers across the country. If we use their
towers, we won't need to build more than 150 relay towers. Each tower
should be equipped with four to six radios that has 100Mbps to 150 Mbps
transmit power. These radios are available now in the market.
If we use radios that have over 50 km to 100 km ranges in near line of
sight (NLOS) situation, we won't even need to build 150 towers across the
country.
Now comes the VSAT. We can use VSAT in the areas where none of the
technology as mentioned above can reach. Therefore we don't need to build
1,700 VSAT stations that the PS - 4 study has recomended.
The truth is that it will take less than three years to get everything
done. It is not that a hard task to do.
Thanks.
