Real engineering + real, patentable ideas...
Wi-Fi signal booster biz Ruckus Wireless has set in motion a $100m stock market debut, and hopes to be listed early next year. The company requested the stock symbol RKUS but didn't specify how many shares will be sold nor which exchange will host the listing - the fields are blank in the initial public offering paperwork …
+ the weirdest piece of advertising I've seen in years.

(so it turns out that was the missing ?? step! Who knew?)
huh? the idea of beam-forming is part of 802.11n - most people decided to ignore that part until 802.11ac comes into play - but the presence (and worldwide legal requirements and regulations) of phased array antennae mean this stuff is known, documented and not just within the remit of one persons/companys patent.
but what shape are the corners??
There is a major difference between 'on chip' beamforming included in 802.11n and 802.11ac standards and Ruckus's directional antennae arrays. The conventional 'on chip' uses signal phasing and omni directional antennaes and may under best circumstances give 1-3dB gain if the client is in just the right spot. The directional antennae array has multiple directional antennae elements and some very nifty RF management software which picks the most favourable pair of elements for each client transmission, resulting in +7dB gain.
This results in very significant performance improvement, particularly at range. In a flood coverage deployment you need less points to cover the same area - Ruckus claim up to 40% less.
Whilst I won't blindly recite the sales mantra, we regularly install and test/survey WLANS from all the established manufacturers. Our Ekahau site survey and Chanalyzer tests consistently show that Ruckus system performs significantly better.
Pantentable - Yes it is and has been, and as a technology innovator Ruckus hold many other patents reflecting its own investment in R&D. As opposed to many of the bigger 'manufacturers' who acquire and sit on the intellectual property of others.
"The basic concept - having multiple antennas and switching between them depending on where the user is - is deceptively simple, but the implementation is a little more complicated."
Oh yes, definitely, takes a lot of development work and much clue from the hardware designers to get this right.
