There
may be a good penetration of BSNL 3G network in urban
areas but still there are some pockets in the city where consumers don’t get
good signal strength, blind spot, for smooth use of 3G services. In Rural area
also, 3G services are not available at many places hence they even can’t think
using of 3G services in rural areas. Consumers residing nearby a mobile tower
may get good signal but still they miss good signal in interior part of a
building.
If
you search the web, you may find 3G signal boosters which works with all types
of dongles but it costs you more than Rs. 8000.
There
is also a tested homemade method by which you can get improved signal reception
in the range of -85dBm to -75dBm.
As a
thumb rule, the signal strength in the range -120 dBm
to -95dBm considered Poor, with this signal strength, you may not be
comfortable with your internet use. The signal strength range from -93dBm to
-85dBm considered OK for use of internet but the signal strength from -83dBm to
-75dBm is Good and if you get signal strength more than -75dBm to -50dBm, that
is excellent signal strength, with full five signal bars on your dongle.
Following
homemade project boost the 3G signal strength from Poor to OK / Good so that you can use Internet comfortably.
• You need one sieve (used in houses
for tea or rice), the bigger you get, it would be better.
• One USB extension cable male to
female for connecting between your USB dongle to USB port of Laptop/PC, you can
buy it for approx Rs. 50.
• Aluminum foil, you may find it in
your kitchen where it is used to pack lunch box for Kids
Now
make a big slit at the bottom of your sieve so that you can fit your USB
extension cable and then connect 3G Dongle to this USB extension cable as shown
in figure-2
• Next wrap Aluminum foil on both side
of sieve, it looks like a “mini satellite” dish
antenna. Mount it on a mini camera tripod or something which you find it
suitable. This mini satellite dish converge the received signal at its
periphery and focus towards the center
of sieve hence 3G dongle at this center of sieve get stronger signal strength.
• Connect your 3G dongle to the laptop
and now turn this “mini satellite” dish slowly left, right, up or down until
you get the most optimum reception, keep a watch on signal bars on dongle
application on laptop.
With
this project, you get an improved 3G signal by 10 to 15 dBm
i.e. from unstable 2-3 signal bars to stable 4 bars.
This homemade project cost roughly Rs. 150 to 200 but with this
low cost, you get relaxed and can enjoy 3G services at far end from a mobile
tower.
With
this project, even consumers living within a radius of 25Km to 30Km of mobile tower
can enjoy 3G services.
This
homemade project also works for 4G-LTE dongles because same principle applies
there.
I
hope, you will definitely get some more ideas for your homemade-project from
below pictures, all are tested projects.
