17-734: The Company sells to a variety of enterprises such as energy, utilities, agricultural, government, defence, water, wastewater , manufacturing, and commercial enterprises. The company also conducts network designs, path studies, and pre-installation engineering services to support its customers. Free Wave Technologies was founded in August 1993, by Jonathan Sawyer and Steve Wulchin. From the beginning, Sawyer and Wulchin aimed to help customers transmit mission-critical data via secure, highly reliable, licensed, and license-free spread spectrum radios. Free Wave has manufactured all of its radios in Boulder, Colorado since

34-468: A Rocky Mountain-based livestock facility implemented a secure ZumLink IQ edge solution with a custom application to monitor water levels in remote tanks from the cloud via an Internet connection. Using the Node-RED programming language, an app was created quickly and easily to gather data from analog sensors. The solution helps drive down operating costs by reducing the amount of travel for visual inspections in

51-487: A drone, FreeWave's technology can monitor remote environments and detect such issues as thermal fluctuations and fallen power lines in real-time. Then the radios can relay information to such parties as fire departments, insurance and telephone companies, and dispatchers. FreeWave's product platform includes edge connectivity and computing technologies designed to support a variety of network infrastructure, communication, and application requirements. Available models operate in

68-428: A single location to multiple locations. Point-to-multipoint telecommunications is typically used in wireless Internet and IP telephony via gigahertz radio frequencies . P2MP systems have been designed with and without a return channel from the multiple receivers. A central antenna or antenna array broadcasts to several receiving antennas and the system uses a form of time-division multiplexing to allow for

85-583: A time-division multiple access (TDMA) based protocol or a polling protocol rather than the CSMA/CA protocol. The telecommunications signal in a point-to-multipoint system is typically bi-directional, TDMA or channelized. Systems using frequency-division duplexing (FDD) offer full-duplex connections between base station and remote sites, and time-division duplex (TDD) systems offer half-duplex connections. Point-to-multipoint systems can be implemented in licensed, semi-licensed or unlicensed frequency bands depending on

102-413: A variety of deliberate applications or processes. Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration ". In everyday usage, wastewater is commonly a synonym for sewage (also called domestic wastewater or municipal wastewater), which is wastewater that

119-612: Is a central base station to which remote subscriber units or customer premises equipment (CPE) (a term that was originally used in the wired telephone industry) are connected over the wireless medium. Connections between the base station and subscriber units can be either line-of-sight or, for lower-frequency radio systems, non-line-of-sight where link budgets permit. Generally, lower frequencies can offer non-line-of-sight connections. Various software planning tools can be used to determine feasibility of potential connections using topographic data as well as link budget simulation. Often

136-440: Is available on its products, providing the ability to program, deploy, and run applications in any Linux -compatible language. FreeWave offers products that include a module, board-level, and enclosed radios for OEM and industrial end-user connectivity and computing applications. Wastewater Wastewater (or waste water ) is water generated after the use of freshwater , raw water , drinking water or saline water in

153-527: Is imminent and transmit images from the top of the volcano. With hundreds of thousands of residents living around the volcano, early warning is crucial to take precautionary measures and evacuate citizens before an eruption can take place. The Geophysical Institute of Peru also uses FreeWave technology to capture and transmit sensor data across a line-of-sight path of up to 127 kilometers (79 miles) at 115 kbit/s or up to 67 kilometers (42 miles) at 1 Mbit/s. At an elevation of more than 6,000 feet (1,800 meters),

170-409: Is produced by a community of people. As a generic term, wastewater may also describe water containing contaminants accumulated in other settings, such as: Point-to-multipoint communication In telecommunications , point-to-multipoint communication ( P2MP , PTMP or PMP ) is communication which is accomplished via a distinct type of one-to-many connection, providing multiple paths from

187-520: The 900 MHz , and 2.4 GHz radio frequencies; support point-to-point (PTP) and point-to-multipoint (PTMP) configurations; utilize secure Frequency Hopping Spread Spectrum (FHSS); and communicate via multi-protocol Serial communication and Ethernet . Systems operate in temperatures from -40 C to +75 C (-40 F to +167 F). Interfaces supported include RS-232 , RS-422 , RS-485 , and TTL . Models are available with 128/256-bit AES encryption and C1D2 certification. FreeWave's IQ Application Environment

204-660: The Mount Washington Observatory (MWO) in New Hampshire uses a FreeWave solution to capture data from six weather stations and transmit the data to an Ethernet-connected gateway. The data provides information such as temperature and wind speeds for MWO's climate research. Weather observations are reported to the National Weather Service and National Oceanic and Atmospheric Administration for use in nationwide and global forecasting models. The operator of

221-564: The event of a problem such as a leakage that prevents a tank from filling. The Sangamon Valley Public Water District (SVPWD) in Mahomet, Illinois , implemented FreeWave radios in a new SCADA system to communicate with remote wells and control equipment and settings from a central location rather than sending personnel to collect data and monitor the water system. SVPWD reported 50 percent cost savings, with savings expected to rise as leaks and inefficiencies are detected and corrected. When strapped to

238-807: The first radio was shipped in 1994. In June 2007, TA Associates led a $ 113 million investment in Free Wave Technologies. The company's major markets are oil & gas , government, and defence, agriculture , water and wastewater , and manufacturing industries since that time. Today, Free Wave Technologies has more than 800,000 industrial radios and embedded modules in the field. FreeWave's wireless M2M solutions are deployed across many industries including oil and gas, government, precision agriculture, traffic systems, water/wastewater, manufacturing, and other utilities. For instance, FreeWave radios are used by energy companies to maximize production and reduce operating costs for mission-critical applications within

255-400: The military, and for environmental monitoring to provide warning of impending natural disasters such as volcanoes. The Institute of Geophysics of Ecuador uses FreeWave technology at Tungurahua , the highest volcano in the world which operates at below-zero temperatures from a height of 5,947 meters (19,511 feet) above sea level. FreeWave M2M devices capture early-warning signs that an eruption

272-409: The point to multipoint links are installed to reduce the cost of infrastructure and increase the number of CPE's and connectivity. Point-to-multipoint wireless networks employing directional antennas are affected by the hidden node problem (also called hidden terminal) in case they employ a CSMA/CA medium access control protocol. The negative impact of the hidden node problem can be mitigated using

289-435: The return channel traffic. In contemporary usage, the term point-to-multipoint wireless communications relates to fixed wireless data communications for Internet or voice over IP via radio or microwave frequencies in the gigahertz range.
