This interoperability testing highlights the benefits to public safety of using open standards based commercial broadband technology. The testing showed that public safety agencies can use a core from one vendor and eNodeBs from other vendors, which represents a major shift from today's single-vendor Land Mobile Radio (LMR) networks, according to a company release.
The RAN and associated backhaul are typically a significant part of the overall LTE network cost. Wireless service providers now use Alcatel-Lucent's eNodeB in commercial LTE networks.
The tested network solution operates in the public safety 700 MHz band 14 spectrum, covering both PSBB and D-block spectrum. Interoperability testing validated a solution using the Alcatel-Lucent eNodeB with a Cisco Evolved Packet Core. Testing also validated a network with an Alcatel-Lucent Evolved Packet Core and an Ericsson and a Nokia Siemens Networks eNodeB.
