Public Safety / Mission Critical
Microlab has a long history in Mission Critical applications. We began in 1949 as a supplier of coaxial components for the Defense and Microwave industries. Since the 1990’s Microlab has become a leader in the emerging commercial Distributed Antenna System (DAS) Market. Our components are approved and in use worldwide by many of the largest Wireless Service Providers.

Our reputation and commitment to quality is second to none.

We were one of the first companies to understand and define the impact of PIM on infrastructure systems. Our products continue to be tested and refined to ensure adherence to the latest standards. Most of our products are IP-67 / NEMA 6 certified. In addition, a new line of salt-fog tested products are being released.

Microlab components cover the majority of Public Safety/Transportation/Utility frequencies with products ranging from 80 MHz through 5.8 GHz.

Public Safety Antenna
The new public safety antenna from Microlab is significantly smaller than standard products offered by other vendors, yet yields similar coverage patterns. The NEMA 4 / IP-65 rating ensures installation compliance. Easy to install, paintable, and low maintenance, the new YA series of antennas are available in various frequencies and formats.

Public Safety Monitor | PSM02/PSM04
In 2015 Microlab began development of a Public Safety Monitor, a unique approach to ensure compliance with IFC 510.1 and NFPA part 72. This device allows for the monitoring of multiple RF sources and is not dependant on the type of signal being transmitted. It also monitors the health of the DAS itself. Since these types of systems are generally not used on a regular basis, it is crucial that there be some mechanism in place to notify the facility of a potential disruption in coverage.

Unlike mobile phone DAS, the Public Safety DAS is not used on a regular basis. The time to find out that the coverage solution has failed is not while an event is happening. The PSM02/PSM04 has been designed to monitor the downlink signal of up to four families of public safety frequencies with virtually no impact on the coverage of the DAS. This means that the Public Safety Monitor can even be implemented in existing installations!

A monthly service can be provided that will send SMS text and/or e-mail notification along with a monthly report that can be presented to the building manager or local jurisdiction to demonstrate that the DAS was fully functional and in compliance. Connection to the unit is via Ethernet IPV4 or IPV6 or an optional wireless modem.
