MIMO LTE antennas handle indoor distribution antenna systems

 Taoglas, a leading provider of IoT and automotive antenna and RF solutions, today announced the launch of the Taoglas iDAS antennas with superior PIM ratings, two new MIMO LTE antennas designed for use in indoor distribution antenna systems (iDAS) to address in-building coverage issues and increasing demand for constant connectivity for indoor locations such as office buildings, stadiums, conference centers, shopping malls, hotels and other areas where high-performance indoor connectivity is required. The iDAS antennas are being showcased this week at Taoglas’ stand (Hall 7, #7G11) at Mobile World Congress 2019 in Barcelona, Spain.

Wireless connectivity has become a major consideration for building owners, as more than 80 percent of wireless data traffic occurs indoors. In addition, buildings need a reliable network to ensure the support the growing use of Internet of Things (IoT) applications, including smart building applications such as smart lighting, heating management, connected security as well as monitoring, pollution and earthquake warning systems. Reliance on the LTE network to handle this traffic poses a problem for large buildings, many of which have little or no cellular coverage.

iDAS networks have emerged as an excellent solution to bring LTE coverage to areas that traditional base stations cannot reach, providing broader, more secure connectivity than the building’s Wi-Fi solution can offer. LPWAN, CAT-M or NB-IoT networks will also benefit from boosting the cellular network in buildings.

Taoglas’ new iDAS antennas deliver powerful 4G LTE MIMO coverage worldwide, while also covering the 3G and 2G bands. The antennas are available in two compact, easy-to-install form factors: A wall-mounted design (iDAS.W.001) and a circular ceiling mount design (iDAS.C.001), both with customizable cable lengths, cable types and connector types available.

4G LTE applications demand high-speed data uplink and downlink. High-efficiency and high-gain MIMO antennas are necessary to achieve the signal-to-noise ratio and throughput required to solve these challenges. Taoglas’ iDAS antennas are also designed for high isolation and low Passive Inter-Modulation (PIM) between the two MIMO antennas to prevent self-interference.
