  By removing wire harness, Wi-Fi is becoming increasingly pervasive in every
aspect of our lives, in both the consumer and industrial worlds. Besides
flexibility, the recent high efficiency and extremely high throughput versions
managed to close the performance gap with Ethernet. However, it still lags
behind Ethernet for what concerns dependability. To this aim, the ultra high
reliability study group has been recently formed. This paper reports on some
preliminary ideas and proposals about the ways seamless redundancy can be
exploited to make Wi-Fi more reliable, yet retaining a good degree of backward
compatibility with existing network infrastructures.
