uhf radio mics

[Ynot]

we are looking to spend around £200/£300

Then I'm afraid, Raymond, that youre not going to get a great deal of quality for that budget. Even the list price on the Sennheiser EW 100 G3 is over £500 EACH.

I am curious about the performance of these units in a busy 2.4GHz wireless environment. Perhaps Don can give us some insight into this?

I'm thinking, venue wireless network, touring wireless network, sound wireless network, lampies wireless network, vidiots with a couple of 2.4GHz camera links, perhaps in a city centre with a dozen wifi hotspots visible, not to mention all the residential routers that you can see.

 

How does this range of digital wireless cope with a busy environment that is, most likely, destined to get busier?

 

Cheers,

This is a very interesting question. The Line 6 website has an interesting selection of marketing technobabble about 2.4Ghz band but no matter how much digital processing you've got, radio is in the end analogue and the basic principles of signal to noise ratio still apply. Would it have worked at one of those recent Apple conferences where so many people had a PDA using wifi that their network demo wouldn't work? What happens if the interference from other 2.4Ghz equipment gets too much?

 

Some results from real-world testing would be interesting.

Ref the RF interference, this point is "exposed" to some degree in this link:

It might be that the 2.4GHz band of freqs becomes a victim of its own success (?).

 

Seeing as how Dan B is probably genned up more than most cf the current posters perhaps a word on how possible interference can be reduced to a minimum? I presume the digital signal is "packetised" (sic) but what about the sheer amount of rf?

 

In the "old" technology radio mics spectrum (VHF & UHF) the main contention would be from other radio mics. In the 2.4GHZ band (aka ISM = Industrial, Scientific and Medical) the kit is designed to be tolerant of interference:

On top of that you have wifi and now radio mics. So, any info on how to manage the radio mic spectrum has got to be top of the agenda for them as use radio mic stuff all the time to earn a crust...and no doubt them as earns a crust selling them, ** laughs out loud **.

So the answer is yes ... there is some amount of interference that gets to be "too much". The question is how likely will this happen in the real world. Yes, it happened at the Apple roll out, but in thousands of Starbucks day after day the wi-fi doesn't crash (not to mention in countless corporate situations).

 

Take a look at my post in the thread about Line 6 wireless for an example.

 

So while it is possible to crash the Line 6 system you must ask how much more likely is it to crash a conventional system. We think an order of magnitude or two, especially if you count hiss, fade-outs and other interference, which is IMPOSSIBLE using the XD-V systems.
