I recently asked the Ekahau site survey tool maker if they could add a feature that allows visualisation of different qualities of client transceiver. The reason I asked is because the range of Wi-Fi client ability continues to expand. Very soon the new Broadcom BCM4354 chip will deliver two-stream 802.11ac Wi-Fi to smartphones. Meanwhile some very old clients are still in use along with clients that have poor design and/or build quality. Some websites report that the Samsung Galaxy S5 should be available in April using the BCM4354 and that the iPhone 6 will also use it. So the Broadcom BCM4354 will rapidly expand to the range Wi-Fi client ability that WLANs are expected to manage. I think that site survey tools should allow me to deliver reports that visualise this diversity of connection quality. If you have to provide a certain level of Wi-Fi service to a diverse set of clients you need to know what they will experience, not just what can be obtained on the high end equipment that WLAN professionals use.
