In today’s blog, we will discuss mobile hotspots, sometimes also referred as portable WiFi. We’ll talk about what they are, what they’re typically used for, and what features you should look for when buying one. We’ll also discuss specific brands that you might want to take a look at, in the United States as well as Asia, the Middle East, Africa and Europe. Let’s get started.
Mobile hotspots (portable WiFi) provide high speed internet on-the-go, using a cellular connection as its backhaul in a mobile, portable form, typically small devices that are portable. These devices are also sometimes referred to as “Mi-Fi”, but this also refers to an actual brand name, so we will avoid the usage. In general a mobile hotspot is essentially a single-SIM Wi-Fi router (although advanced multi-SIM routers also exist, which we discuss below). It uses a single SIM card (like in your phone) to connect to the provider’s cellular network, while connecting to your devices via Wi-Fi. In fact, most smartphones today have an option to put the phone into “hotspot” mode, which turns your phone into a mobile personal hotspot. If you’re sitting out in the park with your phone and laptop, and suddenly need to use your laptop with an Internet connection, you can just set your phone in hotspot mode, and you will see a new wireless network appear in your laptop’s settings that you can then connect to and have high-speed Internet.
So why would anyone need a separate device to use as a mobile hotspot if you can just use your phone? It turns out there are a couple of reasons why this is not practical. A major reason is simply battery life. Using the hotspot mode on your phone places tremendous strain on the battery, and your battery will drain much more quickly. Also, a dedicated mobile hotspot uses much better antennas than your phone, which is especially important in remote locations with no wired Internet. Another nice thing about a dedicated mobile hotspot is that any data used does not come from your existing phone service – typically a separate account is set up for the device, which is very convenient for business users whose company reimburse the expense. And finally, mobile hotspots have significantly enhanced security and other important features that your smartphone can’t match.
There are many use cases for using a mobile hotspot, and while you certainly (probably) know what you would use yours for, some of the other use cases are quite varied and may surprise you.
Aside from the first two use cases, the remaining applications really require something more sophisticated than a simple, single-SIM mobile hotspot. They require enterprise-grade multi-SIM mobile hotspots powered by SD-WAN with broadband bonding.
In these situations, the performance of the mobile hotspots really comes down to the advanced algorithms inside the device. With the right technology, such as SD-WAN with broadband bonding, previously unobtainable performance, such as supporting broadcast quality HD video, can be achieved even in the harshest environments.
So, what are the key features you should be concerned with when researching mobile hotspots? These are the areas you should pay special attention to:
Best Mobile Hotspots Right Now
To come up with a manageable list of candidate mobile hotspots, I scoured scores of recent reviews and pulled out a handful of mobile hotspots that kept showing up over and over again. The best single review I came across was done by PCMag at The Best Mobile Hotspots of 2020. I’ve summarized some of their finding below, along with a couple additional hotspots for international travelling.
The following list comprises the “best of the best” mobile hotspots and should be part of your research before you buy. Note that unless otherwise stated, all these models are 4G LTE, dual-band, single-SIM, Wi-Fi devices. We discuss multi-sim mobile hotspots models later in the article.
This mobile hotspot supports up to 20 devices, uses a 5040 mAh battery (up to 24 hours), weighs 8.5 ounces and measures 4.15 x 4.15 x 0.80 inches. It incorporates some of the fastest hotspot hardware available among single-SIM category, and has excellent access controls. The downsides are its weight and that it has no touchscreen interface – management via web portal only.
Sprint – MiFi 8000 Mobile Hotspot
This hotspot supports up to 15 devices, uses a 4400 mAh battery (up to 24 hours), weighs only 5.4 ounces and measures 4.45 x 2.79 x .74 inches. This unit has a 2.4” color touchscreen display user interface for configuration management.
Verizon Jetpack MiFi 8800L
Connects up to 15 devices with a 4400 mAh battery (up to 24 hours), weighs 5.4 ounces and measures 4.29 x 2.64 x .71 inches. This hotspot sports the fastest 4G LTE technologies along with a 2.4” color touchscreen display.
Verizon 5G MiFi M1000 Hotspot
The only 5G mobile hotspot on the list, the M1000 supports up to 16 devices with a 4400 mAh battery (5-7 hours), weight of 5.7 ounces and measures 4.85 x 3.48 by 1.20 inches. It delivers super-fast performance when connected to Verizon’s limited 5G coverage. Price and coverage make this more of a novelty at this point, rather than a true mobile hotspot, although it works great when there is coverage. Battery life is also an issue.
T-Mobile Alcatel LinkZone 2
Connect up to 16 devices using a 4400 mAh battery (up to 24 hours) with a weight of 5.2 ounces and measures 4.13 x 2.6 by 0.75 inches This device has the lowest cost of any hotpots on the list. But the Internet connectivity is slow and there is no touchscreen – device configuration via web portal only.
International Mobile Hotspots for Europe, Asia, Middle East, and Africa
For international travelers it is very convenient to have a mobile hotspot designed specifically for that purpose. Alternatively, you can purchase an unlocked hotspot and then populate it with loaded SIM cards for the local cellular network. This can be an affordable option, but significantly less convenient, especially if you are travelling through multiple foreign countries.
Many international hotspots use a “virtual SIM” or “cloud SIM” that automatically connects to the local cellular network without using separate SIM cards. They also typically are set up for daily or monthly rentals, which can also be very convenient. Some models may also allow for using a SIM card, which can be nice when you can get good data rates locally.
Note that while all these international mobile hotspots claim 4G LTE performance (max download of 150 Mbps and max upload of 50 Mbps), if the local LTE signal is weak or non-existent these devices will switch to 3G or even 2G mode in order to connect. And of course, even with a strong 4G LTE network, your upload/download performance will normally be significantly less than the theoretical maximums mentioned.
This international mobile hotspot supports up to 10 devices, using a 3000 mAh battery (up to 18 hours), weighing 130 grams and measures 126mm x 68mm x 12.1mm. The Mini Turbo has excellent global coverage in over 130 countries with unlimited LTE data. There are daily rental plans and a 2.4” color touchscreen display for configuration and is cloudSIM compatible
The Skyroam Solis can connect only 5 devices, which may be a problem if you’re trying to provide an entire family or group with high-speed Internet. The device has a 6000 mAh battery (up to 20 hours), weighs 6.7 ounces and measures 3.66 x 3.66 x 1.02 inches. Has excellent global coverage in over 130 countries with unlimited LTE data. There are convenient daily and/or monthly rental plans. SIM-free operation is supported and there is also a slot for your own SIM if desired. There is no touchscreen, so manage the device via a web portal. Proprietary USB charging cables can be inconvenient.
This device also can connect only up to 5 devices using a 5350 mAh battery (up to 15 hours) with a weight of 8.3 ounces and measuring 4.6 x 2.5 x 0.83 inches. Excellent global coverage in over 130 countries with unlimited LTE data. Purchase the device outright or rent it daily or monthly for your trip. Has a 5” color touchscreen display for configuration. Supports SIM-free operation. This device is a bit heavier than the others, so keep this in mind
Enterprise Grade Multi-SIM Mobile Hotspots
Single-SIM mobile hotspots, like the ones listed above, can be super convenient if you’re on vacation and can also provide connectivity when travelling for business. But these hotspots are prone to performance fluctuations, just like your phone and are ill-advised for business-critical use cases. The cellular signals that travel between your device and a provider’s cell tower bounces off of obstacles like the ground, buildings, trees, and signs, and is affected by weather conditions, creating a challenging environment to operate in. Your signal strength will fluctuate significantly as you move around relative to the cell towers and as your local environment changes. We’ve all experienced this with our phones when the signal drops and we start moving around trying to get another bar or two of coverage.
But, it’s possible to combine multiple SIM cards, even from different providers, in a way that significantly boosts reliability and performance. This creates an entirely new class of mobile hotspots, the enterprise-grade multi-SIM mobile hotspot. Since fluctuations on different networks are weakly correlated (i.e. they won’t occur simultaneously), if those multiple SIM connections are intelligently managed by your mobile hotspot using SD-WAN with broadband bonding, a significantly enhanced end-user experience can be achieved to support more demanding applications such as video conferencing or cloud based business applications. Multi-SIM mobile hotspots (or sometimes called multi-WAN mobile hotspots) are mobile hotspots that house two or more 4G LTE modems that can be combined for mitigating fluctuations in signal and greatly improving overall performance and reliability.
Under the hood what these advanced mobile hotspots are doing is monitoring the wireless channels on an on-going basis so that the device can make intelligent and instantaneous decisions regarding which path to take for each Internet packet. These mobile hotspots take advantage of two important technologies, namely: overlay networking and stretched networks.
What is overlay networking?
Overlay networking refers to the VPN-like tunneling that can be achieved over the IP transport. The difference of course is that unlike a VPN overlay, the multi-WAN overlays, such as the ones used in multi-SIM mobile hotspots, can take advantage of multiple WAN Internet connections as well as implementing intelligent algorithms to optimize traffic.
How do you stretch a network?
Stretched networks refer to the concept of being able to extend a local area network with overlay networking. In the case of mobile hotspots, the local hotspot network is extended to the cloud, via the overlay network, to have access to a static IP address. In effect, the terminating side of the overlay tunnel (in the cloud) will have a static IP address and that IP address can be mapped onto the mobile hotspot, therefore acting as if it is the static IP of the hotspot. This is an interesting use case where even though the SIM cards in the mobile hotspot do not have static IPs, the device itself will have access to a static IP and can leverage that to connect to the Internet. This allows for business-critical, corporate applications that depend on static IP addresses to be deployed and used. With a stretched network, these mobile multi-SIM hotspots can also be connected directly to the corporate network via the encrypted overlay tunnel and therefore addressing any security concerns.
Advanced Enterprise Functionality
While all of the mobile hotspots we’ve mentioned in this article perform well and are quality products, they simply don’t have the capability to perform all the necessary functions that an enterprise-grade device must have. Forbes has a nice article where they define what “enterprise grade” means, but we can best summarize by saying an enterprise-grade hotspot needs to have the performance, reliability, and advanced features necessary to accomplish critical business activities.
In particular, when a mobile hotspot becomes an integral part of a company’s network infrastructure, such as providing Internet access for mobile clinics or ambulances, or enabling live video applications, it becomes critical for the device to have all the sophistication of modern network edge devices. A single-SIM (cellular modem) device simply can’t deliver the performance and features necessary. By using an enterprise-grade, multi-SIM mobile hotspot powered by SD-WAN with broadband bonding, an entirely new level of performance and functionality can be achieved. These hotspots provide sophisticated, packet-by-packet routing, robust firewalling, top-notch security (up to AES-256), website blocking, DNS redirection, and traffic engineering via traffic identification, classification, and QoS bandwidth reservations and the centralized device monitoring and management.
Time to Choose
We’ve gone over a lot in today’s blog. Hopefully, if you’re a business traveler or individual consumer, you now have the information you need to make an informed decision about purchasing a mobile hotspot, and you’ve got a handful of great devices to start with.
If you require a mobile hotspot that needs to provide enterprise-grade capabilities that a single-SIM hotspot can’t provide, take a look at the most powerful mobile hotspots on the planet – multi-SIM mobile hotspot/routers powered by SD-WAN with broadband bonding for performance you never thought was possible.
