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

Field Service Is Becoming Part of Compliance for Public Safety Radio Coverage Systems

Field Services Compliance Has Moved Into The Operating Phase No longer considered static, public safety radio coverage systems are no longer simply “accepted” once and then ignored until there is a failure. Public safety radio coverage systems have entered buildings that are being renovated, re-arranged, leased, enlarged, and interconnected with additional radio frequency (RF) systems

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

P25 Control Channel Decode Margin Loss Under Dense Broadband, BDA, and Mobile Command RF Activity

Hidden Failures of the P25 Trunked System Control Channel Public Safety Communications (PSC) agencies rely upon reliable P25 trunked system control channels for successful registration, affiliation, assignment of channel grants, and attachment to a given system resource. While the failure point is typically identified as poor voice audio quality, the first indication of a “hidden”

Satellite to Cellular Public Safety Coverage Extensions and RF Coexistence Pressure Around Ground Based LMR Gateway Sites

Satellite Access Moves to a Public Safety Coverage Layer The new FCC framework for supplemental coverage from space (SCS) allows satellite and terrestrial operators to utilize terrestrial mobile spectrum via defined authorizations and interference protection. This framework utilizes FirstNet licensed 700 MHz public safety BroadBand spectrum, often referred to as Band 14, for SCS purposes

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

Antenna Isolation Degradation Between Adjacent Public Safety Arrays During Tower Loading Expansion

Tower Loading Expansion and Isolation Margin Reduction Public safety tower sites are carrying more RF systems than their original antenna plans anticipated. Regional P25 systems, conventional mutual aid channels, utility radio networks, microwave paths, cellular broadband equipment, and in building donor antennas are often added over multiple budget cycles. Each addition changes the physical and
