    Top 5 Wireless Testing Challenges for IoT and 5G Devices

    The rapid integration of IoT (Internet of Things) and 5G solutions into the existing business landscape is revolutionizing industries, from smart homes to autonomous cars. More connected devices make it challenging to maintain reliable, secure operation and compliance with global regulations. Wireless validation is a critical component of the development process that allows manufacturers to identify and correct problems before products reach the market.

    Fast-Track Your Wireless Product Certification
    Here are the top 5 wireless testing  challenges, which confront manufacturers for IoT and 5G devices —and how Nemko can help you overcome them:

    1. Spectrum Congestion
      With millions of IoT and 5G devices competing for limited spectrum resources, resources, interference is one of the areas of greatest concern. The devices must operate with optimum performance without interfering with other wireless systems. Nemko's wireless test solutions enable devices to operate in areas where they are over-dense and yet remain compliant with spectrum demands. Our advanced testing tools and expertise help catch interference issues early in the development stage.

    2. Co-Existence Testing
      IoT devices usually co-exist with multiple wireless technologies, such as Wi-Fi, Bluetooth, and Zigbee. Co-existence testing verifies that devices co-exist without performance degradation. This is especially critical in use cases like smart homes or industrial IoT, where multiple devices co-exist simultaneously. Nemko's state-of-the-art labs simulate real-world environments to test device interoperability, so devices interact perfectly in advanced ecosystems like smart homes or industrial IoT.

    3. Security Flaws
      The wireless devices are the point of entry for cyberattacks. The vulnerability testing such as weak encryption or unauthorized access needs to be performed to retain user data and not lose the trust. Security testing ensures the devices comply with industry standards and are free from new threats. Nemko security testing services check device resistance against emerging threats while ensuring compliance with industry standards like EU Cybersecurity Standards, RED Cybersecurity, and Cybersecurity Labelling Program for IoT Products by FCC. Our security experts help you implement robust security controls to safeguard your devices.

    4. 5G-Specific Complexity
      5G brings new complexity in the form of higher frequency bands (mmWave), massive MIMO (Multiple Input, Multiple Output), and network slicing. All of these new technologies require to be validated using bespoke methodology to ensure performance, dependability, and compliance with 5G standard. Nemko's 5G test expertise guarantees your devices to perform, be reliable, and be 5G standard compliant. We are at the forefront of testing innovations for upcoming 5G technologies.

    5. Global Regulatory Compliance
      IoT and 5G products need to comply with various regulatory standards and agencies, including FCC (U.S.), RED (EU), SAR (U.S. and EU) and PTCRB (North America). They can be time-consuming and challenging to comply with. Comprehensive wireless testing ensures your devices are in compliance with the local regulations to easily access the global market. Nemko's global certification solutions make it convenient, ensuring your devices are compliant with local laws for easy access to the market. With offices and affiliates across the globe, we offer localized assistance to facilitate your entry into new markets more quickly.

    Why Early Testing Matters
    Tackling these issues early in the development process can save time, cut costs, and avoid product launch delays. Partnering with an experienced testing company like Nemko assures your devices meet the highest standards of performance, security, and compliance.
