9 times out of 10 I have zero lags up to 300' away from the stage where my rack lives. Antenna is on a 10' boom mast. That 10% though... Got to admit it happens! (Wonder what a 50W or more booster might do? Price sure goes up! Would it help though or just add to a wall of noise?) Can't exactly roam the room if I'm leashed so I'm committed to wi-fi. Both friends said they've never had any issue in clubs (probably no more than 100') with an off the shelf router with the X32. The OSC stuff is just a very light weight back and forth of MIDI data. I really need to get off my lazy ass and incorporate OSC into my rig since it literally requires no more hardware. I kind of want to rip off the template they use on the M32/X32 too. I was thinking for a second the XR18 could be an instant little B rig for $500... Oh well. Not doing too many live gigs these days though either. Got burnt out and pissed off.

I understand the positioning of the antenna is a critical parameter (together with the quality of the router device). The antennas should be located in free air with distance to other equipment and above the heads of the public.
Hence I consider the built-in WiFi of the XR18 just a courtesy feature for very simple configuration purpose. In a live situation I would use a router box on a stand, connected to the Rack Mixer by an RJ45 cable. Quote:

50 Watts would only be useful (and legal) in the desert, or so. Both sides would need to have 50 Watts TX power or it wouldn't get you anything. I've never seen 50W Wifi gear that was real. But I've used boosters in the forest to get VHF or UHF to go up to 5 km. It only needed 4 Watts to get there, but it took an entire day to figure out where to put the antenna's... And the same goes for Wifi. If the range isn't what you expected, run some radio analysis software. And move the gear about 4 inches both ways to measure signal strength. That can make a lot of difference. In fact, it's a lot like mic placement

Just had a look at my Utilities folder...
It's awfully empty. Seems I haven't done anything with Wifi since the last clean install... I use Wireless diagnostics mostly, available by ALT-clicking the Wifi icon in the menu bar. That gives enough overview in most cases. If you need more, Netspot will put your routers on a map. Nice to work out how many routers you need to put in and where they should go. I used to use AirMagnet too, but it seem to have been scooped up by the corporate world (Netscout) and they are set to confuse us, by offering at least a dozen different utils for what one app used to do. Quite honestly, I don't remember the Mac tools for Wifi. They seem to have gone very commercial or turned into adware. Must be the appstore's influence. Tried a few minutes to find a few names on the appstore, but this didn't even turn up one suggestion. Loads of VPN and photo sync crap, tho... These days, my colleague who is doing large scale Wifi deployment, uses a cheap router with some open source distro on it to analyse. That thing is put in the location studied and remains there for a few weeks. Data is analysed afterwards.

I would need something more hit and run. I found this app iStumbler way back. It shows wi-fi found and what channel it's on and what signal strength. But that's it.
Something that could make a more visual map and showed any signal in the wi-fi range - not just something specifically transmitting wi-fi protocol - would be a great tool. I took it as far as an antenna mast and a 13db antenna (which flattens the spherical transmission and thus extends it if I understand correctly) and that got me decent results. I know I'm missing a few things though that could probably really help. I'm always annoyed nowadays when the only place I can find to download some software is the freakin App Store. If not OSX software, Linux? Maybe that would motivate me more to gear up to jump ship! |

Going higher with a mast, is very useful with UHF and VHF. It can be useful with Wifi, but the effect is far less.
Just like in acoustics, you're dealing with reflections. And these disturb a clean signal. You need to find the top of the sine wave. But because the wavelength is just centimeters, you just move both tranceivers a bit to find max. signal strength. Wifi is extremely good with elimination of disturbances. That's why lots of devices can operate simultaneously on the same radio channel. VHF and UHF are comparatively bad at that. Because of the longer wave length, they tend to find transmission paths that follow objects like hills and CAN follow a longer path. We used to have offices below a saddle roof. The triangular form caused bad reflections. If I'd put a laptop on the left side of my desk, I'd get no reception at all, despite the router being only a few meters away. On the right side of the desk, reception was perfect... You'll find all you need in the Wifi menu, cause it's basically channel numbers and signal strength you need. The rest is accomplished by walking around. I use my iphone for it, in the rare cases I still use it. The app I use most, is free and called "Wifi mapper". It's not a real serious tool, but it shows interesting stuff, like the approximate distance to the router. Have a look. The iphone is just more convenient when walking around. I used to do it with a Macbook. Sure makes you look geeky When it comes to working in theatres, you might find interference from stuff that uses the Wifi band, but doesn't show up as a Wifi router. I know one spot where it's the alarm system. I've pointed out to management that it means their alarm system is very, very vulnerable. Of course, they don't believe me... Guess I'll have to buy a Wifi killer to demonstrate it... What you need most, is experience. Some of my experience dates back to the times before everything was infested with "Free! Wifi!" Way back then, you'd need to look for a nearby router that was open to get connected in the wild. These days, there's 4G. So i got very lazy...
