DEVICE TESTING Internet of Things (IoT) is being well accepted now and number of connected devices are increasing day by day. One report indicates that there will be 35.82 billion IoT devices installed worldwide by 2021 and 75.44 billion by 2025. Another report from Fortune Business Insights says IoT technology holds important potential in the ICT segment with the worldwide market valued at $190 b in 2018 and hitting $1.1 trillion by 2026. The report projects that the international market will grow at a surprising CAGR of 24.7% all through the estimated years. IoT has moved from industrial- commercial applications to home appliances, personal devices and much more. Smart sensors, wearables, and connected devices will continue to alter the way healthcare is delivered, from automated homes to telemedicine help for the disabled and elderly. Besides, in situations where the risk of virus infection is strong, it will also be used to minimize unnecessary contact.
n the future, manufacturers who develop and manufacture IoT devices (products) expect more customers complaints about problems, such as difficult and dropped connections and short communications range, which will increase support costs. In order to prevent this situation, manufacturers who develop and manufacture IoT devices (products) must evaluate and test the wireless communications quality at the development and manufacturing stages. By testing the quality of IoT devices (products) thoroughly at the development stage and guaranteeing quality, after-sales support problems can be reduced in advance.

Associate Director – Optical Business and Marketing, Anritsu India are assumed to be the most common method used in the IoT market for connecting to the Internet. There is also news about using 5G, LTE, NB-IoT, Cat-M, wireless LAN (WLAN) and Bluetooth for these wireless communications and IoT devices (products) featuring these technologies are appearing. Today there is increasing need to deliver better and faster services. There is a huge demand to access, create, use and share data from any device Anritsu IoT device test solutions and equipment can check and test the wireless communications quality at the above-described development and manufacturing stages of IoT devices (products). They support all wireless communications methods, including 5G, LTE, NB-IoT, Cat-M, wireless LAN (WLAN) and Bluetooth. There will various testing levels in IoT eco system such as unit testing, integration testing, system testing, acceptance testing or functional testing or regulatory compliance testing. ITU -T document Q Series specifies test methods SWITCHING AND SIGNALLING, AND ASSOCIATED MEASUREMENTS AND TESTS Testing specifications – Testing specifications for IMT2020 and IoT.
Also, at manufacturing of IoT devices (products), defects may occur due to component or assembly failure. After-sales support problems can be reduced in advance by testing and checking the wireless communications quality of finished IoT devices (products) at the final stage. Wireless communications
