Citizens of the Earth depend upon United States leadership in this technology for several reasons:
Development: The GPS was originally developed by the US Department of Defense for military purposes, but it was later made available for civilian use. The US has invested heavily in the development and maintenance of the system, which has contributed to its leadership in this area.
Coverage: The GPS provides global coverage, with 24 satellites orbiting the earth and transmitting signals that can be received by GPS receivers anywhere in the world. This level of coverage is unmatched by any other global navigation system.
Accuracy: The US has worked to continually improve the accuracy of the GPS, with current accuracy levels estimated at around 10 meters for civilian users and even higher accuracy for military users.
Innovation: The US has continued to innovate and expand the capabilities of the GPS over time, with newer versions of the system including features such as higher accuracy, improved anti-jamming capabilities, and the ability to operate in more challenging environments such as indoors or in urban canyons.
Collaboration: The US has collaborated with other countries to expand the reach and capabilities of the GPS, such as through the development of compatible navigation systems like the European Union’s Galileo system and Japan’s QZSS system.
United States leadership in the GPS has been driven by a combination of investment, innovation, collaboration, and a commitment to improving the accuracy and capabilities of the system over time.

When the electric grid and the internet are down and there is no cell service, radio can still work to help communities stabilize. Starting 2024 we will break down our coverage of the radio frequency technology standards used in educational settlements into into two categories:
Radio 300: Security and maintenance radio. These usually use a single radio channel and operate in a half-duplex mode: only one user on the channel can transmit at a time, so users in a user group must take turns talking. The radio is normally in receive mode so the user can hear all other transmissions on the channel. When the user wants to talk he presses a “push-to-talk” button, which turns off the receiver and turns on the transmitter; when he releases the button the receiver is activated again. Multiple channels are provided so separate user groups can communicate in the same area without interfering with each other.
As of this posting APCO International has no public consultations on any titles in its public safety radio standards catalog.
Radio 400: Student radio. College radio stations are typically considered to be public radio radio stations in the way that they are funded by donation and grants. The term “Public radio” generally refers to classical music, jazz, and news. A more accurate term is community radio, as most staff are volunteers, although many radio stations limit staff to current or recent students instead of anyone from the local community. There has been a fair amount of drama over student-run radio station history; a topic we steer away from.
The Low Power FM radio service was created by the Commission in January 2000. LPFM stations are authorized for noncommercial educational broadcasting only (no commercial operation) and operate with an effective radiated power (ERP) of 100 watts (0.1 kilowatts) or less, with maximum facilities of 100 watts ERP at 30 meters (100 feet) antenna height above average terrain. The approximate service range of a 100 watt LPFM station is 5.6 kilometers (3.5 miles radius). LPFM stations are not protected from interference that may be received from other classes of FM stations.
We follow — but do not respond — to consultations on titles covering the use of radio frequencies for the Internet of Things. At the moment, most of that evolution happens at the consumer product level; though it is wise to contemplate the use of the electromagnetic spectrum during widespread and extended loss of broadband services.

We do not include policy specifics regarding the migration of National Public Radio beyond cultural content into political news; though we acknowledge that the growth of publicly financed radio domiciled in education communities is a consideration in the technology of content preparation informed by the Public Broadcasting Act of 1967.
We drill into technical specifics of the following:
Radios used for campus public safety and campus maintenance
Student-run campus radio stations licensed by the Federal Communications Commission as Low Power FM (LPFM)
Facilities for regional broadcast of National Public Radio operating from education communities
Off-campus transmission facilities such as broadcast towers.
Grounding, bonding, lightning protection of transmission and receiving equipment on buildings
Broadcast studio electrotechnologies
Radio technology is regulated by the Federal Communications Commission with no ANSI-accredited standards setting organizations involved in leading practice discovery and promulgation.

The frequency differences between public safety radio and public broadcasting radio are mainly due to their distinct purposes and requirements.
Public safety radio operates on VHF and UHF bands for emergency services communication These radio systems are designed for robustness, reliability, and coverage over a specific geographic area. They prioritize clarity and reliability of communication over long distances and in challenging environments. Encryption may also be employed for secure communication.
Public broadcasting radio operates on FM and AM bands for disseminating news, entertainment, and cultural content to the general public. These radio stations focus on providing a wide range of content, including news, talk shows, music, and cultural programming. They often cover broad geographic areas and aim for high-quality audio transmission for listener enjoyment. Unlike public safety radio, public broadcasting radio stations typically do not require encryption and prioritize accessibility to the general public.
NFPA 1930 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council. As part of the consolidation plan, NFPA 1930 is combining Standards NFPA 1801, NFPA 1802, NFPA 1932, NFPA 1937, and NFPA 1962.
Firefighter radio communication faces several special technical challenges due to the nature of the environment they operate in and the criticality of their tasks. Here are some of the key challenges:
Interference and Signal Degradation: Buildings, debris, and firefighting equipment can obstruct radio signals, leading to interference and degradation of communication quality.
Multipath Propagation: Radio signals can bounce off surfaces within buildings, causing multipath propagation, which results in signal fading and distortion.
Limited Bandwidth: Firefighter radio systems often operate on limited bandwidths, which can restrict the amount of data that can be transmitted simultaneously, impacting the clarity and reliability of communication.
Noise: The high noise levels present in firefighting environments, including sirens, machinery, and fire itself, can interfere with radio communication, making it difficult for firefighters to hear and understand each other.
Line-of-Sight Limitations: Radio signals typically require a clear line of sight between the transmitter and receiver. However, in complex urban environments or within buildings, obstructions such as walls and floors can obstruct the line of sight, affecting signal strength and reliability.
Equipment Durability: Firefighter radio equipment needs to withstand harsh environmental conditions, including high temperatures, smoke, water, and physical impacts. Ensuring the durability and reliability of equipment in such conditions is a significant challenge.
Battery Life: Prolonged operations in emergency situations can drain radio batteries quickly. Firefighters need reliable battery life to ensure continuous communication throughout their mission.
Interoperability: Different emergency response agencies may use different radio systems and frequencies, leading to interoperability issues. Ensuring seamless communication between various agencies involved in firefighting operations is crucial for effective coordination and response.
Priority Access: During large-scale emergencies, such as natural disasters or terrorist attacks, communication networks may become congested, limiting access for emergency responders. Firefighters need priority access to communication networks to ensure they can effectively coordinate their efforts.
Training and Familiarity: Operating radio equipment effectively under stress requires training and familiarity. Firefighters must be trained to use radio equipment efficiently and effectively, even in challenging conditions, to ensure clear and concise communication during emergencies.
