In recent years, wireless communications functions have been added to domestic white goods, such as robotic cleaners, refrigerators, washing machines, etc., as well as to industrial products, including digital cameras and sensors. Moreover, the future widespread deployment of IoT devices seems likely to expand the use of wireless communications. In most cases, wireless communications functions are implemented using either wireless LAN (WLAN) or Bluetooth® wireless technologies, but this document describes products incorporating wireless LAN functions. To implement communications functions using WLAN, a WLAN module is generally built into the product/equipment, but the performance described in the catalog for the built-in WLAN module is not guaranteed to be the same as the finished product containing the module. Consequently, when either developing new products or implementing upgrades, performance comparisons with other companies’ products as well as with in-house products is a good way to understand market trends as well as an important step in assuring the manufacturing of better products.
