Measuring PIM on the AT&T FirstNet Network with the Anritsu 2-PortPIM Master™ Application Note
■ In 2017, AT&T won a multibillion dollar contract from the United Sates Government to build and maintain a communications network for first responders, including police, firefighters, and emergency medical services. The purpose of the FirstNet service is to provide a modern voice and data network that allows seamless communications between services, and does not become overloaded during large scale emergency situations. FirstNet users will have priority network access during times of peak demand using dedicated FirstNet handsets. The FirstNet network uses standard LTE bandwidths and protocols in a new block of frequency spectrum.
■ AT&T's commercial LTE network is located in band 17, and the downlink occupies 734 MHz to 746 MHz. The band allocated for the FirstNet downlink is 758 MHz to 768 MHz and the uplink is 788 MHz to 798 MHz. These spectrum allocations lie adjacent to other commercial LTE networks from Verizon and T-Mobile as seen in figure 1 below.
