Unlimited mobile internet
The use of internet would never have become so popular if
mobile internet usage was not available. Having broadband at home or in
the office is very convenient, but when you are out of the house or uploading
photos taken on the beach in Cox's Bazar to social media, cell internet will be
very important, or you can say, you have only one option to access the
internet. Again, if we talk about the rural areas of our country, then
cell internet is their only hope! Many villages still do not have electricity,
and it is a sin to imagine broadband there.
Now back to our main point, why don't mobile operators offer unlimited data
plans? Again, many operators advertise their internet packs as unlimited,
but there is a condition called "Fair Use Policy". This means
that after your internet data usage has exceeded a certain amount, internet
speed will be reduced for that month or for a certain period of time. Why
do they do that?
Well, if you want to understand the whole thing easily in detail, then now I am
going to shake up the knowledge about some wireless network systems. There
are two terms when you use the internet with mobile or the technology used by
mobile operators (SIM companies) to get the internet to you. The first
term is wireless technology, and the second term is bandwidth
connection. If we talk about WIFI hotspots, then why is it necessary to
use hotspot on phone and use internet on PC? Of course, the phone has to
have WIFI and keep the phone's data connection on, right? But what if you
run a WIFI hotspot without keeping the phone's data connection on? In that
case, of course, you will not get an Internet connection, although your PC will
have a WIFI connection.
What does this mean? Not only WIFI, you also need an active internet
connection, then you will be able to broadcast the Internet through WIFI. Mobile
operators also use the same principal. 2G, 3G, 4G - these are just
wireless technologies like WIFI, but you must have a broadband connection to
the cell tower to use them to provide internet access. From that broadband
connection the internet is sent to your phone by creating a hotspot through 2G,
3G, 4G wireless technology. Now mobile towers must have T1, T3 type lines
connected which have a lot of high bandwidth capacity.
So now your mobile internet speed depends on two factors, firstly, how much
bandwidth you have to handle the broadband connected to your tower and how much
of the wireless technology (2G, 3G, 4G) you have connected to the internet. Has
the ability to supply.
For example, suppose you have three wireless routers in your home and a
broadband connection of 200 megabits / second. The three routers work
using 3 WIFI standards 802.11a, 802.11n, and 802.11ac (these are meant to be
compared to 2G, 3G, 4G, respectively). The 802.11a standard has a maximum
bandwidth speed of 54 Mbps, the 802.11n has a maximum bandwidth of 300 Mbps and
the 802.11ac has a maximum bandwidth of 1300 Mbps.
So, if you connect WIFI to Router 1 (802.11a) you will only
get speeds up to 54 megabits / second, there is no benefit in broadband line
speeds up to 200 megabits, because your wireless technology does not have the
capacity to handle that bandwidth. When connected to Router 2 (802.11n),
and Router 3 (802.11ac), you can easily use the full bandwidth of the broadband
line, as these two technologies have the ability to handle all the bandwidth of
your line.
When you think of 2G, this technology does not have the
power to give you more speed, so even if your operator's internet speed is
fast, you will not get good speed using 2G. On the other hand, 3G technology is
not so advanced. 3G does not have the power to accept the speed itself, with
the increase in the user, the bandwidth of 3G technology will decrease, no
matter how high the speed of the net installed in the tower, 3G will no longer
be able to handle the user.
When you switch from 2G network to 3G network or switch from 3G to 4G, it means
you have switched from small radio frequency to large radio
frequency. Your downloads and uploads will pave the way for more volume and
faster access. So not only do operators have to have high speed internet
connections, they also have to have wireless technology to deliver them to the
users.
As the number of users on the mobile network increases, it becomes more and
more difficult to handle the Internet. They have bandwidth but there is a flaw
in the system that delivers them to the user. Suppose 3G technology allows
50 users to use the internet at a good speed from one tower, but if there are
500 users then you will not get good speed even if you have high speed
bandwidth in the tower connection, because 3G itself does not have bandwidth
capacity to handle 500 users.
Mobile operators have no shortage of bandwidth or internet like the rest of the
broadband ISPs, but the problem is with wireless technology, if they release
unlimited PAN, users will increase download / upload a lot, which will cause
new 3w or 4G technology bandwidth problems for users and Or not everyone will
be able to get good speed on average. The main reason for slowing down the
internet when you have a fair use policy is not allowing you to use more
internet (depending on which package you have subscribed to) and another reason
is to provide better speed for more users at that time. Now operators need
to upgrade their network devices if they really want to handle more users,
which is hugely expensive, so they control these issues by reducing bandwidth speeds.
Why is your 3G / 4G speed slow?
Everyone complains that they are not getting good speed even
after being connected to 3G or 4G. You see, if you understand the above
paragraphs well, you must understand that having more users reduces your
internet speed, two things happen here, maybe the broadband connection to the
tower has low bandwidth speed or there are so many users in your area that
wireless technology has its own bandwidth. Can't. It is important to keep
in mind that 3G / 4G technology has its own bandwidth capacity and the lines
installed in the tower have bandwidth capacity.
For example, in a foreign country they get speeds up to 100+ megabits / second
when they win 4, but we get an average speed of 20 megabits / second, so where
is the problem? In fact, the problem this time is the tower's broadband
line, which means the operator does not have such a high-speed internet
line. But 4G technology has enough bandwidth speed, so connecting a high-speed
line to the tower will also increase your speed. Now you can't say that
the operator is not giving you 4G!
Suppose you bought an 802.11ac router with speeds of up to 1300 megabits /
second, but if your broadband connection speed is 5 megabits, then you get only
5 megabits. But this does not mean that your router technology is not an
AC router. Robi is promoting their 4G network as 4.5G, now the term 4.5G
is actually possible, it is not impossible, it means their network has the
capacity to provide 100 megabits + speed but if you do not get that speed then
they must have that amount There is no internet bandwidth or a lot of users so
you are not getting good speed, but this does not mean that their network is
not 4.5 GE. So, you understand, there is a difference between using 3G /
4G and how much speed you can get.
Will unlimited mobile internet ever be possible?
Let's go back to the main point of today's article, you must
now understand why mobile operators can't provide unlimited PAN. This is
because 3G / 4G technology cannot handle as many users and bandwidth, and
operators try to provide more user support without spending money on upgrading
the network. But the question is, will we ever get unlimited mobile
data? Does that mean mobile operators will ever offer that?
Yes, that could happen in the future, but of course with the advent of 5G
technology! Where 4G operates below 8 GHz frequency, 5G will be able to
operate in the 30-300 GHz range. The higher the radio frequency, the
higher the bandwidth speed. To support this huge radio frequency range, 5G
will be able to handle huge data and secondly 4G will be able to support as
many devices per meter as 5G will be able to support 1,000 more
devices. This means that you will get high speed net in 5G, with the
ability to handle many users, mobile operators will then be able to sell
unlimited plans. Able to but how much speed you get will depend on how
much bandwidth the operator has. If operators increase their bandwidth or
simply install high speed broadband in their towers, you will get it too, as 5G
will handle them comfortably.
