Long Service Life Is Becoming a More Important Measure of RF Infrastructure Value

Long Service Life Is Becoming a More Important Measure of RF Infrastructure Value Infrastructure is typically analyzed in three ways: (a) through specifications; (b) through quoted price; (c) through delivery schedules. While each of these criteria are important, none address the full cost of owning and maintaining equipment that may serve your needs for decades.

Everyday Maintenance Habits That Prevent Long Public Safety Radio Outages

Everyday Maintenance Habits That Prevent Long Public Safety Radio Outages Public safety radio outages can occur due to many factors such as a malfunctioning power source, broken feed line, environmental alert, or network issues. The length of time for the outage is typically caused by something much less dramatic then what initially started the outage;

Emergency Communications Lifecycle Planning Makes Spares Documentation and RF Site Maintenance Part of Public Safety Readiness

Lifecycle Planning Has Become an Operational Requirement Emergency communications planning no longer just decides when radios should be replaced. Now it impacts inventory of spares, control of documentation, maintenance records, scheduling field service work and being able to sustain public safety communications support after acceptance. Guidance from CISA, SAFECOM and NCSWIC treats emergency communications as

MCX Interoperability Maturity Increasing Pressure on Legacy LMR Sites to Support Broadband Voice, Data, and Video Coexistence

MCX Maturity Moving Toward Operational Interoperability Broadband for mission critical applications is transitioning from standards discussions into actual operational interoperation. ETSI’s tenth Mission Critical Services Plugtests, which tested mission critical services (mc) in 4g and 5g networks, indicated an interoperability success rate of approximately 92% of the overall tests conducted. The tests evaluated mission critical

AI Video, Drone Telemetry, and Incident Broadband Cells Increasing Temporary RF Noise Exposure Around P25 Command Post Receive Paths

Incident broadband load becomes the receive path problem Incident scenes today have more transmitters than there are frequency slots in the static LMR plans. In addition to P25 portable repeaters and interoperability gateways, incident scenes have vehicular routers, body camera docks, unmanned aircraft controllers, broadband modems, satellite terminals, temporary LTE or 5g cells, etc. In

Band 14 Growth Changes the Receiver Protection Problem

Band 14 Growth Changes the Receiver Protection Problem The growth of public safety broadband isn’t eliminating LMR from critical communications architecture. Rather, it’s moving broadband systems closer to narrowband P25 receivers that were designed for earlier assumptions regarding rf density. FirstNet will continue to utilize Band 14 spectrum for public safety broadband purposes as part

Code Driven Coverage Expansion and RF Density

Code Driven Coverage Expansion and RF Density Radio Frequency (RF) emergency responder communication coverage systems have evolved from an infrequent special purpose installation to a standard component of public safety communications planning in new buildings, renovated facilities, tunnels, campuses, hospitals, schools, high-rise structures, and hardened public venues. The International Fire Code utilizes emergency responder communication

Public Safety Sites Transition From Individual Network Systems to Shared Radio Frequency (RF) Environments

Public Safety Sites Transition From Individual Network Systems to Shared Radio Frequency (RF) Environments Public safety communications have transitioned away from stand-alone local mobile radio (LMR) networks. Many agencies continue to rely on P25, analog mutual aid channels, conventional LMR channels, trunked LMR systems and dispatch center RF infrastructures for mission critical voice. At the

Co-located (and) Broadband Pressure Inside Public Safety RF Sites

  Co-located (and) Broadband Pressure Inside Public Safety RF Sites In today’s growing public safety communications environment, many densely populated public safety communications sites will house both P25 LMR transmit and receive infrastructure and mission-critical broadband systems. For example, there could be commercial LTE carriers; public safety broadband equipment; microwave backhaul systems; and in-building coverage

Cavity Filter Thermal Drift Effects on Adjacent Channel Rejection in High Duty Cycle LMR Sites

Thermal Stress in Modern Public Safety RF Sites High duty cycle LMR sites increasingly operate inside shared RF environments that combine P25 trunked systems, conventional mutual aid channels, utility radio systems, microwave equipment, and broadband public safety services. The result is a higher continuous RF load on passive infrastructure than many legacy sites were originally
