Antennas for mesh networks

28 April 2010 Telecoms, Datacoms, Wireless, IoT

Taoglas has launched a full range of antennas for the building of full mesh networks. All mesh networks require three types of antennas: base station antennas, remote external antennas and remote internal antennas. Taoglas provides a solution for all three antennas in multiple frequencies including cellular, Zigbee and ISM. All antennas can be customised or used off-the-shelf.

The Barracuda range of base station antennas are omnidirectional units that connect directly to mesh access points and telemetry units. They are available at 433 MHz, 868 MHz, 915 MHz, 2400 MHz and 5200 MHz for operation in the main licence-free bands used for M2M applications. These antennas have aluminium mounts and high power handling internal copper elements. The Barracuda range is entirely customisable, and can be made in different frequencies, colours and shapes in order to match the access point box. Design options include a connector integrated into the base of the antenna so the antenna can be screwed directly to the access point, eliminating cable requirements and helping with waterproofing and secure connection for long term use.

The antennas’ electrical design mitigates the use of materials that result in performance loss, delivering high efficiencies across the spectrum. Different gain versions of this antenna are also available at each frequency. Taoglas panel, sector-panel and yagi antennas provide coverage for dead spots and backhaul point-to-point.

External remote antennas are still required where no signal is present at an installation point that is underground or close to metal, or where manufacturers need to run a cable to an area of signal so a unit can connect to the mesh. The Hercules range of external antennas has been upgraded to meet the demands of these harsh mesh network requirements for remote monitoring, metering and M2M markets. Available in GPS, cellular, WiFi and ISM bands 433 MHz, 868 MHz, or 915 MHz, this range includes a thick thread and nut for a secure mounting solution. Taoglas also has the ability to customise cables and connectors including low-loss special cables with armoured options.
