What is an example of a long range technology?
Applications requiring such range involve the monitoring and/or control of some equipment or system. Examples include the smart grid, electricity, garbage collection and utility water or gas metering. Other longer-range uses include city lighting control and agriculture monitoring..
What is long range communication?

What is range communication?
The range of communication is the distance over which signals can be transmitted. The greater the range, the farther two people can communicate. This range can vary depending on the type of communication system used. The three main types of communication systems are vernacular, visual and written..
What is the difference between short range and long range communication?
When set to short range, more data is sent between the speakers. This means that the audio quality is slightly higher than when Long range is selected. However, there needs to be a near-perfect wireless connection between the speakers in order to send this much data reliably..
What is the range of communication?
Range is defined as the maximum distance where communication can exist between two antennas in a wireless network. But range is not only about distance. Here are some important considerations: Obstacles, terrain, and radio physics all affect range.Dec 10, 2021.

LoRa stands for Long Range Radio and it is a wireless protocol specifically designed for long-range, low-power communications.
Ultra-wideband (UWB) is a high-performance communications protocol that's an optimal solution for interference-free short-range wireless transmissions. It's low-power and cost-efficient. UWB has a high bandwidth for precise tracking, data collection, and communication.
When set to short range, more data is sent between the speakers. This means that the audio quality is slightly higher than when Long range is selected. However, there needs to be a near-perfect wireless connection between the speakers in order to send this much data reliably.
Dec 10, 2021Long range radio communication is suitable for some IoT use cases; others require short range or cellular. The best choice depends on many
Dec 10, 2021With line-of-site range of 2 miles, it's ideal for building automation, factory-wide controls, smart city solutions and large-area agricultural
Telephone and telegraph service over wire and radio systems between correspondents located at great (virtually unlimited) distances from each other.
Do you need a long-range communication device?
If you need to communicate over long distances without a cell signal, a high-quality set of long-range walkie-talkies or two-way radios is necessary (unless you’ve mastered smoke signals). I’ve used long-range communication devices for years in the military, working security, hotel operations, and also in the mountains while camping and hunting.
What is a long range 2 way radio?
From what I know, a long range two way radio can either be an FRS (Family Radio Service) or GMRS (General Mobile Radio Service) unit. But technically, they are the same as they both work on the UHF frequency band. These 2 way radios long range support communication between a group of users as well. Why do you need a long range two way radio? .
What is a long range transceiver?
With 2W power output for operation, the long range transceiver is capable of providing loud and clear conversations for your team within 5 miles. There are already 16 pre-programmed stations at the UHF frequency range of 400 – 470MHz for each radio.
What is the best communication tool for a large group of users?
The best communication tool for a large group of users is undoubtedly a long range two way radio. Equip your crew with the best long range two way radio for reliable long-distance communication that you are attracted to in this article. There are also helpful tips and a detailed buying guide to help you out. 9.37 x 7.05 x 4.65 inches 1.
What are low-power and long-range communications?
Recently, new technologies that enable low-power and long-range communications have emerged
These technologies, in opposition to more traditional communication technologies rather defined as "short range", allow kilometer-wide wireless communications
Long-range technologies are used to form Low-Power Wide-Area Networks (LPWAN)
What factors affect wireless radio communication range?
Contact us for help with your decision making
Wireless radio communication range depends on many factors, including the location of the intended use case, whether it is mobile or fixed, the distance to cover, as well as obstacles and noise
What is a short range radio?
Short range radios keep power, size, heat and cost to a minimum
They are the perfect solution for residential energy monitoring, commercial building automation, or high-density greenhouse sensing
Communication long range
Acoustic hailing device, sound cannon and sonic weapon
A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance. It has been used as a method of crowd control, which has caused permanent hearing damage, having an extremely high decibel capacity. Other uses have included for negotiations in siege situations to deal with piracy at sea; for mass notification during natural disasters or other emergencies; and by defense forces, including several navies.
The Long Range Certificate is an internationally valid certificate issued to radio station operators. It entitles the holder to participate in marine communications on leisure crafts using Marine VHF, Medium Frequency, High Frequency radios and Inmarsat satellite communication as agreed in Global Maritime Distress and Safety System.
Warhead travelling by its own means, great distances to hit ground targets
The Long Range Land Attack Projectile (LRLAP) is a canceled precision guided 155 mm naval artillery shell for the U.S. Navy's Advanced Gun System (AGS). LRLAP was developed and produced by Lockheed Martin Missiles and Fire Control, the prime contractor being BAE Systems.
The Long Range Strike Bomber (LRS-B) is a development and acquisition
US Air Force program in support of Northrop Grumman B-21 Raider development
The Long Range Strike Bomber (LRS-B) is a development and acquisition program to develop a long-range strategic bomber for the United States Air Force, intended to be a heavy-payload stealth aircraft capable of delivering thermonuclear weapons. Initial capability is planned for the mid-2020s. A request for proposal to develop the aircraft was issued in July 2014. The Air Force plans to procure at least 100 of the LRS-B aircraft at a cost of an estimated $550 million each, with potentially as many as 200 units being considered to enter service eventually. A development contract was awarded to Northrop Grumman for its B-21 Raider in October 2015. Due to the sensitive nature much about the project is highly classified and little information is available to the public. As of late 2019, it was known that construction of the aircraft had commenced, and on December 2nd, 2022, it was unveiled to the public.
