3G Versus 4G for Refurbished and Used Cell Phones
Author: Paul Wise

Refurbished and Used Cell Phones are capable of 3G and 4G
speeds while costing less than comparable technology that's
come straight from the factory. Refurbished BlackBerry
Cell Phones are very inexpensive compared to their
brand-new counterparts, even though they run on the latest
technologies like 3G and 4G.

About 85% of the world's cellular phone users are running
on either 2G or 3G technology. Though considered relatively
slow, with limited data rates, 2G is preferred by over 70%
of the cellular network market.

In the last few years, new networking technologies are
being developed to offer faster data transfer in
competitive rates and a wider bandwidth - such as 3G. 3G
offers up to 2Mbps data transfer speed, but practically
speaking its max speed is closer to 400kbps. Three
quarters of cell phone users still prefer 2G over the new
networking technology. That might change soon.

HP and a Japanese development company, NTT DoCoMo, are
developing a new technology, 4G. It is estimated that 4G
technology will be launched in Japan in the next 6 years.
There aren't enough details about this new technology so we
can't really compare it to anything we have now, but it
looks like it's going to be a lot faster, using wider
bandwidth, and cheaper - or in one word: BETTER.

Whad we DO know about 4G is that with 4G, we will be able
to make a video conference call - 3 or more callers - and
video will be transferred a lot smoother, thanks to the
wider bandwidth. Those devices will have wireless internet
in bandwidths wider than that used by 2G technologies,
never before seen in a mobile phone - 100MHz; which will
also cut costs on large data transfers, and will make video
and music downloads cheaper. New security features will
help better protect users from theft and fraud, and network
security will get much tighter.

Data transfer speed reaches new levels with the new
technology: up to 1Gbps (!). Some features that were
supposed to be included with 4G seem as if they were taken
from a sci-fi movie about the future. Researchers are
working on features that would allow the cell phone user to
know the direction from which the call is coming and how
far away the caller is. Also, we will be able to speak
using our other senses as well, or without having to use
our vocal cords at all. These features will probably not be
ready in time for the launching of 4G, but developers
promise "they'll come in time for 5G."

Meanwhile, until we get 4G technology in the United States,
we will soon have a kind of in-between technology dubbed
super 3G. There's not much information about this
technology, besides that it is planned to have a high speed
data transfer of up to 100Mbps.
