Sensors are widely used to pilot various technology subsets, like wearable gadgets, mobile phones, and countless smart devices.  Being the heart of so many smart devices, sensors need to go through meticulous validation and verification process to deliver the best performance to users.  Find out how Allion’s Fusion Sensor Validation can help.

With its versatile applications, wireless network has become an indispensable part of our lives. However, in real-life scenarios, we are seeing a lot of connection problems that can lead to user dissatisfaction.
Allion Wireless Network Solution includes regular checkups, field inspection, long-term monitoring of wireless signal to ensure your network quality in all circumstances, 24/7 .

Since the past, indoor Wi-Fi has not had common performance testing standards, which has led to manufacturers defining and performing their own tests. This phenomenon causes confusion in users when purchasing related equipment as product features cannot be compared across brands without common ground. This year, the international NGO Broadband Forum, together with manufacturers and laboratories, developed the indoor Wi-Fi performance test standard, and in February 2019 released the first in-home Wi-Fi performance test standard, TR-398 Wi-Fi In-Premises Performance Testing (the “TR-398 Standard”).

In the previous article, we briefly introduced the background information of the TR-398 Wi-Fi In-Premises Performance Testing (the “TR-398 Standard”) and the significance of the launch of this test standard. We also introduced the environment setup and requirements in a more in-depth manner starting from the scope of impact of the TR-398 Standard. In this article, we will continue from where we ended in the last article and explain the test items (bandwidth) of the TR-398 Standard.

From the last two articles of this series, we believe that everyone now has a deep understanding of the background and meaning of the TR-398 Standard and the test environment setup requirements. Of which, we also briefly introduced the two major test categories of the TR-398 Standard: Receiver sensitivity and bandwidth, and their test items. In this article, we will introduce five mandatory test items of category 3, coverage, and category 4, multi-user support, and their test cases.

TR-398 is the first industry-standard to address the Performance test of Wi-Fi APs and routers. The TR-398 standard is divided into 5 categories and we previously introduced coverage and multiple STAs performance In this article, we are going to introduce the last two test category: Stability/Robustness.

USB4™ Specification was recently released by the USB Implementers Forum (USB-IF). Here are the highlights of USB4™ as stated by the USB-IF:
◆ Two-lane operation using existing USB Type-C cables and up to 40Gbps operation over 40Gbps certified cables
◆ Multiple data and display protocols that efficiently share the maximum aggregate bandwidth
◆ Backward compatibility with USB 3.2, USB 2.0, and Thunderbolt 3

Allion was recently authorized by the Wi-Fi Alliance as one of the first test labs worldwide to provide Wi-Fi CERTIFIED 6™ certification testing. As of today, Allion is also the only test lab in Asia to offer comprehensive testing regarding all Wi-Fi certification programs.

Wi-Fi CERTIFIED 6™ is a certification program based on the IEEE 802.11ax standard. A great leap in coverage, capacity, and performance to its predecessors Wi-Fi 4 and Wi-Fi 5, the latest Wi-Fi 6 offers higher data rates while enabling lower battery consumption in devices. This makes Wi-Fi 6 a great candidate in Wi-Fi services at public places, and environments with densely populated IoT devices.
