Fair Wi-Fi coexistence is a key principle in LTE unlicensed design - if we replace one Wi-Fi node with LTE-U or LAA, the remaining Wi-Fi nodes should not be negatively impacted, in many cases they are actually better off. A key benefit of LTE-U and LAA is better performance than carrier Wi-Fi through extended coverage and higher capacity, especially for dense deployments. The combined effect is that an operator switching from Wi-Fi to LTE-U/LAA will get more than 2X performance increase without negatively impacting neighboring Wi-Fi.
Qualcomm has demonstrated fair coexistence at many global events such as CES and MWC and performed extensive over-the-air testing in the lab and in the field. Extensive Industry collaboration across the Wi-Fi and mobile industries are helping to further refine coexistence, to ensure that LTE Unlicensed is a good neighbor to Wi-Fi.
