Learn other ways you’ll be able to access a 4G connection on your Raspberry-Pi-based IoT tasks!
Ways to Connect Your Raspberry Pi to 4G
We’ve all seen our share of IoT tasks and so they all often have one factor in common: they depend on
a Wi-Fi hotspot that they make the most of to hook up with the Web.Connecting to the Web by way
of Wi-Fi hotspot works completely superb in the event you solely need to use the ultimate product
at residence or wherever you’ve entry to a Wi-Fi hotspot. However what if you wish to use the gadget
on the go or depart it out within the subject to gather knowledge and transmit it to a server? In such
a case, you’ll have to make use of a mobile community to transmit knowledge.On this article,
I’ll describe a number of strategies you need to use to connect your Raspberry Pi to a 4G network.
Use a Devoted HAT
A Raspberry Pi HAT is an expansion board that’s particularly made and examined to work with
a sure model of a Pi. They’re just about the identical factor as shields within the Arduino universe.
Nevertheless, in contrast to modules and different smaller expansions, HATs often carry out extra
demanding duties.Utilizing a dedicated HAT, for instance, a SIMCom SIM7600E-H LTE SMT EU
which makes use of the SIM7600 chip, is a clear strategy to join your Raspberry Pi to a mobile community.
This HAT choice makes use of the SIM7600CE for 4G.
Ways to Connect Your Raspberry Pi to 4G
Needless to say the above choice is only one instance and there are numerous extra completely
different modules and HATs on the market that work simply as nicely.Be certain that to do a little
analysis to search out the correct one on your tasks, as a result of a few of them supply extra features,
like GPS help, and others lack in some, like the power to hook up with a 3G or 4G community
(which might completely defeat the aim).Nevertheless, one factor that such HATs typically
have in frequent is their value — they’re fairly costly. Moreover, setting them as much as work
with Linux is usually a ache, particularly for brand spanking new customers.
Use a Simple Shopper Wi-Fi Modem
As I discussed, HATs might be fairly costly, so I often make the most of a easy consumer-grade
USB modem to get my Raspberry Pi linked on-the-go. There may be all kinds of fashions on the
market to select from, however I like to recommend that you simply go for a USB modem that
units up a Wi-Fi community. This lets you join your Pi in the identical means you’d at residence
.A modem that I steadily use for this function is the Huawei E355. Nevertheless, it was extremely
arduous for me to search out that specific mannequin. You could have to search for another,
just like the Huawei LTE E8372 modem (PDF). For this methodology, the modem creates a wi-fi
community that the Raspberry Pi can connect with.I extremely advocate this methodology —
particularly in case your Pi can connect with a Wi-Fi community out-of-the-box
(which all new fashions do).
Such modems are extremely low cost, simple to make use of, and often very dependable,
which makes them the go-to resolution for me.
Use a Easy Shopper USB Modem
In the event you can’t discover a modem that places out a Wi-Fi community, you’ll be able to
all the time attempt a mannequin that makes use of the Raspberry Pi’s USB port to speak with it.
The Huawei E303 modem is one I’ve had success with. Observe that that is an outdated gadget,
however there is a motive I nonetheless use it. It’s extremely tough to get most USB modems to
work correctly and reliably with the Raspberry Pi. As soon as you discover one which works,
keep it up!
The Huawei E303 works when you’ll be able to’t discover a modem that places out a Wi-Fi community.
These gadgets are available and even cheaper than the Wi-Fi choices, making them an excellent
different in the event you’re on a funds and know your means round Linux.
Use Your Smartphone: A Fast and Dirty Different
Do not need to depart your Raspberry Pi unattended? If you already know you’ll stick round your
Pi whereas it communicates, you’ll be able to all the time use your smartphone to create a Wi-Fi
hotspot and join your Raspberry Pi to that community. That is often essentially the most cost-effective
resolution as a result of just about everybody has a smartphone these days.
You may all the time use your smartphone hotspot as a method of building 4G!

A Few Extra Concerns
Needless to say you’ll want a SIM card and, most often, a legitimate contract to attach your Pi to
a mobile community, which provides to the price of your venture.Moreover, the cheaper variants
of modems, just like the 2G ones, won’t work reliably in all places. Acknowledge that, in the event
you select a less expensive different, you could battle to discover a sign particularly in rural areas
the place the reception might be worse.
