For information on the antennas included with cellular Opengear devices, accessories and third party antenna options, please refer to this article.
All current cellular Opengear devices include two SMA antenna connectors (MAIN and AUX). We recommend connecting both SMA connectors to antennas for improved reception and enhanced 4G LTE throughput.
Improved reception: Dual antennas can improve connection stability in areas with poor cellular coverage by utilizing what were previously seen as interference paths (where wireless signals “bounce” off of objects and arrive at the receiver at different times), for multiple radio paths to the cellular tower. This is known as spatial diversity.
Enhanced throughput: 4G LTE Opengear devices (-Lx models) utilize MIMO (Multiple Input Multiple Output) wireless technology to provide increased link capacity, spectral efficiency and improved link reliability. MIMO takes a single data stream and breaks it down into several separate data streams and sends it out over multiple antennas.
