AeroComm's Mesh-ready AC4790 Peer-to-Peer Transceivers Smooth Data Flow, Boost Range.LENEXA, Kan. -- AeroComm eases networking for a wide variety of industrial control applications with true peer-to-peer technology, embedded Inserted into. See embedded system. into new AC4790 transceivers. AC4790s remove the server from an RF communication system, facilitating fully expandable mesh networking Mesh networking is a way to route data, voice and instructions between nodes. It allows for continuous connections and reconfiguration around broken or blocked paths by “hopping” from node to node until the destination is reached. . The wireless solution complements AeroComm's popular server-client-based AC4490 transceivers, giving any OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and the flexibility to choose the protocol that best suits the application. By utilizing a dynamic addressing scheme, AC4790's protocol supports independent communication between any two in-range transceivers in an RF network. Each transceiver "node" knows exactly which other nodes are within talking distance, as well as the signal strength of each one. The OEM is able to design routing sequences that optimize the network without bogging down system performance. "Both flexibility and reliability are vital to a vast array of network architectures," said Mike Varady, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of AeroComm. "In AC4790's intelligent addressing mechanism, we embed software 'hooks' so an OEM can have complete control of the routing schemes. This maximizes the efficiency of the network, while allowing the OEM to alter the architecture as necessary." Multiple node groups may also communicate simultaneously, supporting system scalability. Traffic is forwarded seamlessly from node to node, across a virtually endless range. An optional API command processor controls packet delivery and acknowledgment (on a packet-by-packet basis) and reports to the host device, greatly reducing OEM software development. Additionally, AC4790s feature industry-leading 25ms sync times and SenseAdjust -- a software-controlled RF desensitizer that wards off interference. As with all AeroComm 900MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. transceivers, the AC4790 family utilizes field-proven FHSS (Frequency Hopping Spread Spectrum) See spread spectrum. technology, employs data-encryption standards and supports transmit-power levels of up to 1 watt, providing for extremely long range between nodes. AC4790 supports hundreds of industrial applications, including those where devices must be able to communicate with one another seamlessly. Some examples are automatic meter reading Automatic meter reading, or AMR, is the technology of automatically collecting data from water meter or energy metering devices (water, gas, electric) and transferring that data to a central database for billing and/or analyzing. , industrial automation, vending control and utility monitoring.

Quantity pricing for 1,000 units starts at $39 for 200mW devices. AeroComm Inc. has played a major role in the short-range RF industry for more than a decade with consistent technological advances in both performance and price. The company made waves in 1994 by gaining FCC (1) (Federal Communications Commission, Washington, DC, www.fcc.gov) The U.S. government agency that regulates interstate and international communications including wire, cable, radio, TV and satellite. The FCC was created under the U.S. approval for the first 2.4GHz spread spectrum transceivers. Soon after, it introduced its groundbreaking $200 digital sequence commercial module. In 1996 AeroComm shifted to frequency hopping A wireless modulation method that rapidly changes the center frequency of a transmission. See spread spectrum and 802.11. for greater interference immunity in any environment. Its innovative design techniques resulted in superior modules using inexpensive materials -- producing a cost-per-module that suited vastly more applications. AeroComm broke the $100 price barrier in 1998. Responding to the growing demand for affordable yet versatile wireless, it quickly developed the first complete line of 2.4GHz OEM RF transceivers. These products were backed by the company's own fully automated radio testing system, measuring all critical parameters and assuring the highest quality. Today the company continues to support myriad applications where wireless was previously cost-prohibitive. Its robust proprietary technology, manufacturing and testing guarantee reliable communication, while lower frequencies and fewer parts allow for reduced prices. Additionally, AeroComm has adopted the motto of "Instant Wireless" -- a commitment to facilitate fast and easy RF integration. Visit www.aerocomm.com for more. |
