As businesses expand technology offerings and extend their reach with various network devices, reliance on Wi-Fi reduces expandability and connectivity options. Devices must have Wi-Fi available to perform their designated tasks, which limits their range and functionality. 


Instead of relying on a Wi-Fi connection that limits devices to a specific location, 2021 might be a good time to investigate MiFi (short for mobile Wi-Fi). A MiFi router is a mobile hotspot that uses a 4G LTE SIM card to receive data and transmit that data as a Wi-Fi signal to connected devices. 


A SIM card operates the same way a cell phone operates, so the range of MiFi routers mimics that of a cell phone carrier's range. 


MiFi routers are becoming popular as a means to connect remote devices that are part of the internet of things (IoT) network. These types of devices include sensors, smart lockers, digital signage, unmanned kiosks, and security cameras.



No two IoT organizational implementations are the same, so routers come with a wide variety of features. Here are a few points to consider when choosing the right equipment for your business.



Some routers cater to worldwide business needs, and others operate solely in North America or the United States. If your organization has global business needs, you will want to make sure your router choice supports that option.



All routers provide some level of security. In some specific business scenarios, you may want to invest in routers with higher levels of security. For example, if you are providing health-related kiosks or processing payments, you will want increased security options.


Number of IoT Devices

Some routers have caps on the number of devices that can connect to their Wi-Fi. Depending on business needs, you may need to consider future scalability when choosing equipment. 



If you are operating sensors or equipment in areas with extreme temperatures or humidity levels, you need equipment that is designed to work in those environments. Some MiFi routers are made for extreme conditions, and others are meant to stay inside climate-controlled areas.



Certain routers are designed to have multiple network failover options. If your organization needs consistent uptime, you will want to take a close look at a dual SIM mixed with Ethernet options.

Digi Transport WR11 XT



The Digi TransPort WR11 XT is a router with cost-optimized 4G LTE connectivity. It operates globally and supports multiple cellular networks.


The device is small at 3 inches by 4 inches and 1 inch tall. Its aluminum enclosure makes for sturdy and rugged construction, and the combination of flanges, and an optional DIN rail clip, provides flexible mounting. 


The WR11 will work in temperatures ranging from -30 to 70 Celsius (-22 to 158 F), although they note that reduced cellular performance may occur above 60 C (140 F). It will also work in humidity ranges from 5% to 95%.



For most regions of the world, the WR11 supports LTE Cat 1 router connectivity, although, in some areas, it uses LTE Cat 3. Data transfer rates vary between Cat 1 and Cat 3 implementations with Cat 1 speeds running 10 Mbps download and 5 Mbps upload and Cat 3 speeds at 100 Mbps download and 50 Mbps upload.


The WR11 has dual mini-SIM slots for cellular failover. It does not have a USB port, which could affect certain deployment strategies. In addition to 4G/LTE connectivity, the WR11 can also use 3G. 


The WR11 does not support Wi-Fi, so it requires separate Wi-Fi equipment for a true MiFi experience.



The WR11's security features include logging, redundancy, firewall protections, and VPN. For these functionalities, no annual enterprise software license is required which provides companies with additional flexibility.


Security is managed through the Digi Remote Manager (Digi RM), the cloud-based platform for security management. This system allows managers to update firmware, monitor traffic, edit configurations, and automate tasks remotely. 


Digi RM can facilitate mass configurations, support, and maintenance for easy management of hundreds or thousands of remote devices.



The Digi TransPort WR11 XT is an excellent choice for organizations needing global deployments or operations in extreme temperatures. The WR11 offers extensive security options, and it could be a serious candidate for the best 4G router for worldwide implementations.
