[Technology] How well do your RF systems operate in the presence of other wireless devices and avoid interference?

Extremely well, mainly because our special circuit designs and proprietary radio protocols are thoughtfully designed for that purpose.

Our unlicensed systems must operate in close proximity with a variety of similarly unlicensed RF products – wireless network hubs, cordless phones, Bluetooth equipped PCs and peripherals, and other commercial wireless devices. But that’s not a problem for either Reply-brand or OEM-brand systems that Infowhye designs and manufactures. And here’s why.

All our new wireless products operate in unlicensed frequency bands enabling them to be used virtually anywhere in the world (2.4 GHz, for example) employ proprietary communication protocols. Moreover, our specialized communications methods are proven to be exceptionally tolerant of the interference that commonly occurs in unlicensed bands. That’s because:

  • Reply systems set up a secure network that doesn’t talk or listen anything like commercial devices that use standardized radio protocols. That means other RF devices don’t mess with our systems, and our systems are designed -- and certified by competent major regulatory agencies -- not to mess with them.
  • Reply devices are synchronized so that a vote/response sent is indeed a vote/response received. This orderly method of communications has several advantages over asynchronous methods (even when those disorderly alternative methods are standards-based). Also, visual displays on each keypad we build acknowledge data transfer success to the user.

  • SSo if you’re concerned about interference, remember that not all RF is the same. Make sure your audience response system is designed to avoid the interference posed by other RF devices. Also, look for one the uses a TDM method to prevent it from interfering with itself.

    And don’t blindly trust in commercial RF protocols, since many of those protocols were standardized for low volume networking and/or are not synchronized. Many of those alternatives depend on multiple transmissions to send data in hopes of that critical data eventually getting through to the base station. Their implementation might be characterized as follows: the more devices, the more retransmissions, the more data, the more potential for self-interference. That makes them inherently noisy, and it adds an element of chance to their solution.

    We’d like you to avoid both of these interference problems. You can with the systems we build. Give us a call. Let’s interact.
