LA-RICS Continues LTE, LMR Site Buildout
Wednesday, June 06, 2018 | Comments

Los Angeles Regional Interoperable Communications Systems (LA-RICS) is planning Long Term Evolution (LTE) round two with the primary objective of site augmentation of the round one system. The new round two sites will be selected in collaboration with AT&T.

Last year, LA-RICS Joint Powers Authority Board approved an agreement that would transfer public-safety broadband network (PSBN) assets to AT&T, as part of the First Responder Network Authority (FirstNet) nationwide public-safety broadband network. AT&T and LA-RICS are committed to providing a smooth and seamless transition to the NPBSN in the months ahead, an e-newsletter said.

As focus shifts away from LTE data sites and the resolution of any outstanding items, LA-RICS lays the foundation for steady production of new LMR builds throughout this year. Preparatory activities for the next wave of LMR sites are the highest priority in the program schedule. Prior to construction, geotechnical investigations are conducted to produce reports detailing soil conditions and design recommendations for structural support and safety.

LA-RICS is engaged in various levels of outreach with local communities and public-safety entities to ensure confidence in the capabilities of the network, before conducting ground-disturbing work, the e-newsletter said.

More than two thirds of the LMR sites have been environmentally cleared. Nearly one-third of sites in the LMR design have been completed. The overall network design was finalized, and outstanding sites are under various stages of development. LA-RICS and Motorola Solutions continue to revisit the drafting table for potential improvements on individual designs.

The buildout plan for the LMR network entails completion of 60 sites by 2020. When fully deployed, the network will provide coverage to public-safety users throughout the entire county of Los Angeles, including the Los Angeles Basin, the Los Angeles Coastline, the Angeles National Forest and Santa Catalina Island. 

Path surveys have been completed on all microwave links, verifying line-of-sight connectivity between LMR towers. Procurement of radio equipment will span the duration of the site construction phase. The LMR project team plans to test and turn up equipment for initial testing as sites draw to completion and will test the network regionally prior to testing the system as a whole.
