But I would also like to point out that while many of us tend to think all those WiFi IPs are dime a dozen, the fact that RivieraWaves was the first in the market to offer Wi-Fi 802.11ac IP for smartphones and tablets might tell something about the entineering team.
Further for other wireless connectivity technologies in development at RivieraWaves, Ceva CEO mentioned during the intervew: 802.11ah, 802.11p and newer versions of Bluetooth.
25 licensees in 4 years? Ha. Ha. Ha again say I. Its a count of IP licensing deals from before even RW was invented. And no, there is no big market for such IPs. And umm... annual licensing revenue of $22-24 million IS chump change.
