WMAS

So instead of the 1:1 device to base unit we're moving to a single base unit actively managing n devices bidirectional, automating corrections, frequency changes, and intermod management for mics and iems?

Took them long enough!!

Is the automated spectrum management into a single base unit really all this is, or is there something more interesting going on under the hood? If you read Shure's article it implies something innovative on the RF side itself, like a new version of TDMA.

Has anyone tried this out yet in testing? I wonder what frequency coordination is going to look like.

There is no frequency co-ordination required. 

It will occupy an entire TV Channel block (6 MHz or 8 MHz depending on location)  It will then be up to the user to manage how the available bandwidth is used.  

Obviously, the bandwidth available within a fixed TV block will not be infinite - so users will chose between latency, quality and IEM / MIC channel counts -  so long as your requested configuration does not require more than the available bandwidth (think data transfer) -  

still very cool!

As far as I know, so far testing of this device has been internal to Sennheiser,  but I guess it will be more widespread in the coming months.   And...from what I have heard, it performs extremely well, even in very dense RF environments.

This is like the new wireless system from Sound Devices. Extremely high channel count in a tight space. The tech is amazing. I’ve seen a demo of the Sennheiser. The cost per channel is extremely high. There is no official price yet but I’ve been told to expect the 6-8k per channel range if not higher.

The Sennheiser WMAS system has had some pretty extensive field testing
to date in both more controlled environments (e.g. theatrical
productions) and large scale highly RF congested environments (think
Super Bowl and World Cup). Once the coordination (which channel to
assign the WMAS) and deployment workflows are understood, deploying at
large scale highly RF congested events will actually, I believe, be far
easier and just as reliable (if not more so).

Henry! So glad to hear you're weighing in for such a long time I hadn't heard anything from you and I thought maybe you weren't well but between you and Volker Schmidt that's where I take all my lead in RF.

The Sound Devices system, which I think is phenomenal, is not WMAS; it's
still one RF carrier per channel. It's that one of the beauties of their
form factor is a single 1RU frame contains a lot of receivers, and a lot
of processing power.

Sennheiser's implementation of WMAS is not for low channel counts. It
becomes cost competitive per channel with the other top tier offerings
once you get to the point of filling a TV channel with single
channel/carrier products.

Gerry,

Good to hear from you. Hope all is well. I'm still around, just playing in a different sandbox (sports television and special events) in the same playground (entertainment production).

Volker and his team did a fantastic bit of R&D on this product. Shows you what mobile services engineers can do when you show them there's life below 300Hz and above 3kHz!

I have demo’d this system from Sennheiser. 

It is a game-changer.

Yes:  The coord is a different approach, it’s about finding a band and doing the work within the unit’s bandwidth. The units are doing digital communication and hopping as needed to insure solid bi-directional paths that are sonically fantastic.  

As far as “ took them long enough”

I have been a consultant/contributor in the development of several of the more recent RF products to come to market from the major manufacturers.   I, and several other engineers & designers who deal with both large format RF rigs and large format IEM rigs.- so that becomes “We” - have been asking the major players to develop a transceiver for well over a decade, and here is the first product we’ve seen that does it functionally- and WAY better than functionally, in low noise floor, ease of operation, and beautifully designed kit. And it can work on a world-wide scale. 

No small feat. Actually… very impressive tech. 

Now: it will be a while before most people’s budgets will allow them access to these products. Think 1046 price per channel, which is a steep buy-in. But I look forward  to hearing the next reports from premiere shows and events using this technology!!

Just to clarify, the system doesn't hop; what it does do is dynamically
create up to three simultaneous notches if a narrowband (<200kHz)
interferer(s) is/are detected. Otherwise it simply statically occupies a
TV channel (with a small bit of guard band included).

Thanks for the correction, Henry. Perhaps I got more marketing speak than engineer-speak in our onsite demo :) Accuracy is key...much appreciated!

Yes - I meant that testing was done by Sennheiser - I did hear about the Superbowl testing Everything I heard is very positive and will very much look forward to watching this develop

THanks
