Top Considerations When Purchasing a 4G Router

We have discussed the best Sailsky routers above that you can choose from. The question is that how would you identify the most suitable model for your application? Remember that the selection of a 4G LTE router depends on various factors. Here are the top considerations when purchasing a new 4G router.

1. Use Case

It is the most critical factor to keep in mind when looking for a 4G router. How you plan to use your 4G router is an important question to be answered. Do you need it for your retail store or outdoor use? Are you looking for a 4G router for your specialty vehicle? Or, do you need the router as the alternative internet access for your home?

If you need a router for your home, you should opt for a router, such as Sailsky XM286N indoor router. If you want a router that you can easily carry in your pocket on the move, the Sailsky XM41 portable Wi-Fi hotspot could be the right choice. Therefore, your use case plays a critical role in the selection of the router.

2. Industrial Application for 4G Routers

If you want a 4G LTE router in the industrial use case, like the branch office backup connectivity, then the router should have some advanced features. These features can be broadband bonding, app-centric optimizations, firewall, etc. Therefore, it is essential to weigh your options when you need a 4G router for a specific industrial application.

3. Will the Router Be the Failover or Primary Connectivity?

It is essential to know whether the 4G router you want to buy is the failover or primary connectivity. If the router needs to carry traffic constantly, it will be the primary internet connectivity means. If it is the case, we recommend you look for a reliable 4G router with multiple cellular connections.

Now consider a failover-only situation. You need a 4G connection to ensure internet connectivity for a limited time. In this scenario, having a couple of connections could be the right choice. Therefore, it is another important consideration to keep in mind.

4. Carrier Diversity

Having just one 4G connection to use in the 4G LTE router can sometimes prove costly. Just assume that you are using one network and it gets down during an important task. Your router allows you to use just one particular network. At that time, you could not do anything, but wait and hope that the network becomes stable again. It will waste a lot of time.

Now think if the router supports multiple carriers. You could have just switched to another carrier and resumed whatever you were doing. This is the reason why carrier diversity plays a key role. Make sure that your 4G router supports at least two cellular connections.

5. Traffic Profile

The traffic profile is another critical consideration when buying a new 4G router. For instance, you have IP traffic with higher SLA requisites, usually real-time apps like video conferencing, chatty apps, or VOIP, etc. In that case, make sure that the router has application aware-flow management traits. These could be as radical as the “VOIP Armor”. Different flow types require different network characteristics. Therefore, it is essential to know the traffic profile before you invest in a new 4G router.

6. Use Case Environment

How do portable WiFi routers work depends on the environment type where you will use the router. If you are planning to use your router in a harsh environment, you should invest in a ruggedized router. Specific environments may also need certain certifications, like train installations. In this scenario, it is essential to ensure that the router is ruggedized as per the spec. It will ensure that the router will perform perfectly against excessive vibration, temperature extremes, etc.

7. Do You Need Any Special Features?

Some 4G routers come with some special features like a firewall, DHCP server, layer-7 filters, advanced QoS, etc. Before you opt for any 4G router, you should match these special features with the requirements of your use case. Buying a 4G router without matching its special features with your application requirements could end up buying the wrong router.

Apart from the above considerations, you also need to ensure that you are investing in a high-quality 4G router. Never buy a cheap quality router just because it is available at an extremely low price. If you prefer cheap price over quality, it would result in premature failure or unstable performance of the 4G LTE router.

Conclusion

Most businesses are using 4G routers either as the main or backup internet access. These routers are available for different use case scenarios, such as indoor and outdoor use. Therefore, when buying a new 4G router, it is essential that you choose according to the specific requirements of your application. You should look for a router with multiple network support and one that fulfils your specific requirements.

Provide a stable network for the home office, allowing you to enjoy 5G speed.
