Good budget comms system

We are a house of worship that runs about 400-600 per service. We deployed this system along with 3 wireless packs for mobile camera operators and a backstage manager. We found it works well for our usage, but had to find what worked and what didn't. When we first had the system and tested in an empty church, we set it at the front of house mixing position, and it worked through multiple walls to all needed locations without drop out. When people filled the church and we tried using it for the first time, we had some drop outs with our backstage guy. The problem seemed to be when the signal went through a wall, because our camera operators were in line of sight of the base station and had no issues. Called Bosch, and was told to go with a directional high gain antenna pointed at the stage (base station comes standard with an omni antenna). That fixed it. After 2 months of usage with full auditoriums + running 2 cams on 2.4ghz + wireless dmx over 2.4ghz, we have had virtually no drop-outs, even backstage and through up to 5 walls (with metal studs in them!). Impressive, even by older radio comm standards. People's milage will vary with any wireless system and prior research for available spectrum is important when investing in anything wireless; we knew that we had open 2.4ghz channels and made sure our public wifi's channels weren't close. Just keep that in mind when considering this system. Pros -Inexpensive decent comms system -long battery life -transceivers come with a charger and rechargeable battery -easy setup -works with telex/RTS/clear-com wired systems -directional high gain antenna optional Cons -operates on open wifi channels, which are potentially susceptible to dropout due to crowed spectrum -signal doesn't propagate through walls like older radio comms could -voice fidelity not as good as wired or older radio comms

Great- until you have an audience...

We are a small University theatre department, and have owned the BTR-240 for 3 years. When we have the BTR in our small venue (less than 50 people), it works great- very clear on the headset, great range, no interference, very reliable. However, when we move it to our larger venue (200-300 people), it works well during technical rehearsals, but the quality begins to degrade during performances: interference, dropped signal, variable volume. It is completely unreliable for a show. I spoke to RTS tech support, and then a Sales Manager about the BTR-240. Their answer: the BTR is built on 2.4g wifi. Things have changed since the unit first came out- between the wifi routers in the building, the computers/tablets/phones of the cast & crew, and the phones of the audience- the 2.4g spectrum is totally swamped, and the BTR is not able to secure a reliable signal through all the interference. When I asked for possible remedies (software updates, antennas, etc), the Sales Manager had some helpful hints for antenna positioning, but both people at RTS said that the system was inappropriate for my venue, and should be replaced. When asked (since they still sell this unit) what an appropriate venue for this unit would be, the answer was Venues that do not have wifi. Maybe rural areas, or the woods. The BTR-240 had a lot of promise, but is not reliable.
