4RF is a world class designer of industrial radio with products in over 150 countries for critical infrastructure including oil and gas, utilities, smart grid, and other applications.
 
4RF reinvented the SCADA radio space with the introduction of the Aprisa SR+ based on QAM modulation.  This technology is now standard for field area networks that operate in FCC / IC licensed bands as well as private market spectrum at VHF, 220 MHz, UHF, 700, and 900 MHz.  The new frequency hopping Aprisa SRi radio is now shipping in volume for applications suited to the unlicensed 900 MHz ISM band. The Aprisa family is manufactured in the USA.

These radio offers a common interface and feature set with great ease of use.  Networks are easily implemented with highly secure communications, flexible IP L2/L3 networking, and support for legacy protocols and migration.  Standards-based industrial hardened serial and IP interfaces are combined with superior RF performance, an advanced over-the-air interface, outstanding reliability, and robust performance in temperature extremes.  The Aprisa family is joined by a recently announced Aprisa LTE gateway product for both public carrier and private LTE networking
