Why we need use 4G sim card router?

Even if 5G is coming and finally will be widely used in worldwide, now 4G is still the main mobile network. In the times, if you do not know 4G and do not use 4G LTE network, it stands for you are behind of the times.

What advantages does 4G sim card router owns? What benefits can 4g sim card router bring to our life and M2M applications?

We will look into some of cases that 4G sim card router might be good solutions. We will also highlight some of the potential shortcomings of a 4G sim card router for certain applications. Overall, we would like to dive deep into the aspects that matter when choosing a 4G router. Now let’s begin:

4G networks are inherently unpredictable. This means, even though in ideal locations, times and environments, the performance of a 4G sim card router can be fantastic. The carriers you use make a difference. Some carriers have the largest coverage area, some carriers have the best urban performance, some are better in rural etc. So you should usually expect variation on the performance based on carriers. It is not uncommon to see one carrier outperform one in a certain location at a certain time, while the following day the roles may reverse.

With all these base level factors in mind, let’s investigate what factors and features you should consider in a 4G sim card router:

1) Which affect you choose a 4g sim card router?

This is perhaps the most important factor in determining the features you need to look for in a 4G sim card router: how will you be using the 4G router? Is this for a retail store as a back up on an existing primary wired connection (imagine the backup Internet for a POS register)? Is the 4G router going to be used in a specialty vehicle (imagine a police car with surveillance cameras)?

If you are considering using a 4G router as a primary Internet connection for every day usage in a residential environment, you are probably a year or two early as the cost of the data has still not gotten to levels where you can replace your wired Internet line with a 4G router. A 4G router should be considered only when you have no other wired Internet options in your house. For this type of simple setups, a 4G router that can house a single wired WAN and a single 4G connection will be a good choice. We recommend 4G router with built-in modems so that you can use an external antenna for best coverage.

2) Do you have an industrial case that needsthe 4G sim card router?

Before choose a 4g sim card router, first you need consider that whether you have a industrial case in need of 4g sim card router, such as a backup connectivity for a branch office, or as a primary connectivity for a mobile or temporary office, then your 4G router needs to support some advanced features including firewall, broadband bonding and application centric optimizations. Ideally, you can have the 4G router capability within your primary router. In this setup your wired line can failover on to a bonded set of 4G connections. Bonding 2 or more 4G wireless connections will provide not only a wider bandwidth and higher throughput, but will also provide self-healing capabilities for the traffic going over 4G networks. Think of it as adding another lane onto your high-way. Compared to a single lane high-way, a 2 lane high-way will always outperform. Broadband Bonding feature will give your cars driving on that highway to dynamically switch lanes, so to speak and therefore shielding network problems, fluctuations and outages from your applications. This naturally brings up our next aspect to consider.

3) Will your 4G sim card router be your primary or failover connection?

IF your 4G router is going to be carrying your traffic all the time, i.e. will be your primary means of Internet connectivity for your office, specialty vehicle or similar, then we highly recommend 4G routers with more than 2 cellular 4G connections. Going back to our high-way analogy, this will mean a larger capacity highway to carry more cars with ease. For failover only scenarios, where the 4G connections need to keep the connectivity alive for only limited time, having only 2 connections might be enough. We still caution against a single 4G failover for the following reason.

4) What type of environment will the 4G sim card router be used in?

It is important to have ruggedized 4G router in case you will be using the device in harsh environments. Certain environments may even require their specific certifications, such as installation in trains where certification for train installations is a must have for your 4G router both for performance against temperature range, vibration tolerance etc, as well as for safety reasons.

5) Which brand 4g sim card router will be good choice?

There are so many kinds of 4g sim card routers in the market. There will be many good choices for you, but I suggest you consider E-Lins Technology as one choice. And E-Lins will show you many excellent 4g sim card routers.
