Wireless Wisdom works in any environment

Intercom

High-quality wireless intercom systems provide reliable low-latency communication in a range of situations from production facilities, construction sites and shopping malls to stadiums and military installations. All these situations require robust, power-efficient and reliable intercom systems. The underlying technologies and specifications can be very different. RTX has the expertise you need to ensure your intercom system performs as do your customers.

Using our in-house developed IP and protocols to eliminate the effects of multi-path fading and interference, we have helped many companies get their intercom products to market successfully across a wide range of protocols and frequencies from 400 MHz to 5.8 GHz.

From initial idea to large-scale production and delivery, we can design, customize and/or build your wireless intercom system to combine high-quality sound with a reliability that’s second-to-none, even in challenging environments.

We spend the effort needed to really understand the application and the use cases. With more than 10 years in Intercom, we posess deep application knowledge and with our customers we will clarify the rest.
