These modules are subject to higher industry standards especially for reliability and security. They also come with more automotive-related features.

Understand Your Applications and Your Service Provider

UnderstandYour Project

Before you choose an IoT module product,the first and the most basic thing is to understand your product and servicesin order to choose a communication technology that best meets your project. Each use case has unique connectivity requirements. Choosing the IoT module with the best features, bandwidth, and price balance for each use case is a crucial step in achieving business and revenue goals. This will require customers to understand very fundamental requirements:

- The scale of deployment and the environment where your device/service will be used.

- Hardware, software, and network setup for the project.

- The data volume, accuracy and latency requirement for the project.

- The range coverage, and mobility needed for the device/service.

- Expected power consumption of the project

These requirements will decide the optimal communication technology to be used in your project. Although numerous available modules of the same communication technology are quite similar in terms of module dimensions, data rate, power consumptions, and hardware/software features, you will be able to find several models that tailor-made for your product. But to find a module that can really contribute to the revenue and the healthy growth of your business, you will need to dig deeper beyond the specifications on the datasheet.

Select an Optimal Network Service

Never forget the fact that your IoT deployment is heavily relying on the network service provided by operators. Understanding the connectivity requirements of your project will also help you to choose an operator, which is also vital for an IoT deployment. Although the price of modules is becoming more affordable with technological advancement, the cost of connectivity remains high since it is a long-term cost with many value-added service options. To calculate the connectivity cost, you will need to comprehend the projected numbers of connections and data volume of your project, compare the monthly or annual fee plan offered by different service providers, and research their available value-added services that will help you grow your business.

A module provided by an experienced and qualified provider like Fibocom is certified by major global operators, which will allow you to rapidly launch your product in the market with a wide variety of network service options. Unlike modules manufactured directly by cellular companies that only work with their own network and satellite system, modules offered by professional module manufacturers, by supporting worldwide operator networks, allow you to scale up your deployment for a global reach.

Choosing a Reliable Module Provider

Besides comparing the specifications provided on the module datasheet, there are also factors unobservable on the written materials that will lead to the success or failure of your projects.

Higher One-Time-Off Cost VS. Re-Occurring Problems and Risks:

As more small and new module providers emerge into the IoT market, many cheaper IoT modules are becoming available to customers with extremely attractive tag price. If we simply look at the initial deployment cost of using cheaper modules, it might look like that it saves a lot of money for the customers. But is the quality of these modules guaranteed? The process of developing a new product and making it deliverable to the market takes long and is costly. Low-quality modules always accompany a higher risk of malfunction and, to the worst extent, result in the failure of the whole project. This will not help IoT companies to generate expected project income, in reverse, it causes a greater loss in investment. From a long-term perspective, even if the product was launched to the market, the unstable performance of the module is likely to cause unwanted surprises and require frequent maintenances. This will not be simply a higher operating cost to the business, it will also harm the reputation of the brand and damage the customers’ loyalty. For the long-term growth of the business, choosing a reliable partner and quality-guaranteed module products is wise and worthy.

Future-Proof Solutions

Good module companies will not merely focus on popular products for the current market, they also look into the future trends of technology and consider technology transition of the solutions. Good providers have the ability to upgrade the software to ensure their modules can continuously support the IoT devices during the network technological transition from LTE to 5G. The module’s capability of working under different IoT network standards will also allow customers to deploy their products in different countries and regions where levels of network development are varied. This will help customers who consider a global business expansion to reduce R&D costs and accelerate the product launch processes. Good module providers also put emphases on the security of connectivity. They work with the world’s leading cybersecurity companies to deliver encrypted module solutions that can effectively avoid cyber virus attacks or information leaking.

Comprehensive Support

It is important to partner with an experienced industry leader like Fibocom (we have more than 20 years of IoT module experiences) which can provide comprehensive pre-sales and post-sales services and supports. By establishing localized teams and offices, global module providers are able to react to problems and crises in a more professional and efficient manner to minimize the business loss of customers.
