rswanson, I also worked on designs where phase noise was a real problem. But that was around 2.5 GHz. We used some nice freq synthesizers, with some proprietary techniques. Such approaches can significantly reduce the phase noise.
Yes I am aware of this (and have had to deal with it in the wireless protocols for the products I've developed). I understand that currently the carriers are're looking at the TV band, but its only a matter of time as the wireless world fills up. What then???
At a public event, both WiFi and cell infrastructure is heavily utilized, primarily for downlink. I'm looking for a way to enable a small number of roaming video cameras to uplink live video at around 4-6 Mbps. Any thoughts?
in the 60 GHz band the biggest challenge is the RF front end and of course phase noise is an issue at such high frequencies. The techniques to deal with it are well guarded by the companies developing solutions.
Were the University of Michigan and the auto makers involved in the development of DSRC? I've read a of a very similar vehicle peer-to-peer type network that they worked on - perhaps this is today's DSRC.
Thankyou Fanny. I'm curious about how phase noise at 60 Ghz is effectively controlled or tolerated. In my work in the past, close in phase noise was a real limiting problem. Can you suggest links I could look at that address this issue?
Yes - the licensed carriers want to buy spectrum, particularly in the TV band. There are FCC auctions that are about to happne whereby TV spectrum could be sold off to the carriers and this will diminish the availability of shared spectrum to the unlicensed users.
Hi Fanny, it appears that the licensed carriers are pushing to take over the unlicensed bands. If that's true (and successful) that would force all the "little guys" to buy bandwidth from the carriers. Is this an accurate picture?

I have a question unrelated to the presentation. Is there a mechanism for participants to contact one another outside the presentation? I ask because I deduce that participant 78RPM and I might share an interest in old recordings, and I would like to explore that.
