Antennas for iDAS applications

30 January 2019 Telecoms, Datacoms, Wireless, IoT

Wireless connectivity has become a major consideration for building owners. As 80% of cellular connectivity occurs indoors, the reliance on the LTE network poses a problem for large buildings which have little or no cellular coverage.

Taoglas thus provides a selection of iDAS (indoor Distribution Antenna Systems) which will facilitate and provide coverage for smartphone usage and wireless internet to support smart buildings.

Applications are extensive, and cover smart lighting, heating management, connected security as well as monitoring, pollution and earthquake warning systems. Many hospitals, airports and stadiums will have reliable Wi-Fi but cellular coverage is still necessary for building owners. Cellular coverage has advantages over Wi-Fi because it is broader and is, therefore, more suitable for IoT. Furthermore, cellular data is encrypted whereas data over Wi-Fi is not, making it a more secure solution for payment systems.

Networks using the LPWAN, CAT-M or NB-IoT protocols using mobile networks will benefit from boosting the cellular network in buildings. LTE public safety networks in the US (FirstNet) and the UK (ESN) rely on cellular connectivity. While building infrastructure created problems for effective public safety communications in the past, iDAS creates a solution for building owners and for first responders.

Finally, the installation of iDAS antennas decreases costs for the building owner because there is little or no need to install a large number of Wi-Fi routers in the building, since cellular coverage is sufficient in order to decrease dependency on Wi-Fi connectivity.

Taoglas’ product range includes the iDAS.C.001 ceiling-mount omnidirectional antenna, a compact LTE MIMO circular antenna with high performance and low passive inter-modulation (PIM). It covers the frequency bands 699-960 MHz, 1710-2700 MHz and 3400-4000 MHz, for worldwide coverage of 4G, 3G and 2G bands. It measures 218 mm in diameter and 40 mm in profile, and carries an IP67 waterproof rating. Also available is a wall-mount model, the iDAS.W.001 MIMO.
