Do M2M Devices need 4G LTE?
Do machine-to-machine
(M2M) applications like sensors, card readers, and IP cameras need 4G LTE? The
answer is yes. More and more M2M devices require 4G LTE to transfer big size
data.
What
is 4G LTE?
LTE is the name given to one of the most recent
high-speed cellular communication protocols currently in deployment. It is
sometimes referred to as “4G,” although the early releases were closer to
“3.5G.” The suitability of LTE for an M2M device depends on several important
factors, such as availability and cost, device form factor requirements, device
lifespan..
What’s the difference
between 3G and 4G LTE? The average speed on 4G is much faster than 3G, so it
makes downloading or uploading data easier.
A
Brief History of LTE
LTE was first introduced in 3GPP’s specification release 8
in 2009, during which 5 different User Equipment (UE) categories were
introduced. Each UE category defines a downlink and uplink speed and MIMO
support capability. UE categories are necessary for the base station to
determine the type of device and setup the link to it accordingly. In subsequent
releases, more UE categories were introduced, including CAT-0 category in
Release 12.
3G or 4G,
which is the Right Fit for Your M2M Device?
At first glance, LTE may appear to be more
appealing to consumer type electronics, such as smartphones and tablets,
defined in higher categories in the table above, but not so much for low speed,
low data volume devices such as most M2M applications.
If
your data is small, then 3G is enough for your application; but if your data is
big size, then have to use 4G to provide faster downlink and uplink. For
example, when you use IPC, it requires higher network speed to ensure the
application’s stability.
SIM Card Router needs
4G or not?
SIM Card Router is also
an important part of M2M, and it has been widely used in many cases and projects in
M2M. Of course sim card router also upgrades to 4G. Just because many M2M
applications require much faster DL and UL speed for data. Now 5G is coming and
finally sim card router will be upgraded to 5G to meet the market’s needs.
