Wi-Fi Certified 6 Release 2 adds new features to address growing demand. Wi-Fi 6 Release 2 packs new punch: better uplink, power management.
Wi-Fi Alliance updated certification ensures better uploads and power use. Wi-Fi 6E certified products. With product use cases growing and complexity increasing, automated Bluetooth and Wi-Fi interoperability testing is now becoming essential.
But QA leaders still need to provide the direction of testing. And doing so requires a deep understanding of the potential issues and problems end users may experience. Over the last two decades, Bluetooth and Wi-Fi have made huge progress. Yet eight common interoperability issues remain present in Bluetooth and Wi-Fi products -- despite big improvements in compatibility, power demands and range over recent years. Use this 8 point checklist to ensure your testing regime covers each potential issue before you go to market.
There is no clear and consistent operable range for Bluetooth connections. Instead, it varies significantly between devices and in different environments. In cars, for example, we have found that effective Bluetooth signal strength varies within the cockpit depending on how many people are in the car. Different devices support the Bluetooth stack in different ways, even though devices may follow the Bluetooth specifications and achieve certification, there still remains implementation differences that lead to interoperability issues in the field.
This can have an effect on the usability of the infotainment system when used with certain devices. Spotting and rectifying causes of interoperability problems during testing can help to eliminate end-user frustrations. Initial pairing and establishing a connection is the first step in any Bluetooth connection process. Some devices regularly disconnect the link and, in some cases, fail to reconnect. We have also found some device manufacturers produce units that are optimised to perform well on either Android or Apple devices - with good performance on one coming at the expense of good performance on the other.
Wi-Fi data transmission speed throughput may not meet expectations, leading to poor user experiences from connected services such as on-demand video streaming.
Other challenges that can affect Wi-Fi include client authentication issues with access points or routes where the user is unable to connect over Wi-Fi, but for no clear reason , and general stability and long-term connection reliability, where random drop-outs can lead to poor download latency and data stalling.
