AeroComm Introduces 868 MHz Spread Spectrum Wireless Module for OEMs
5/15/2003 - Able to replace miles of cable in harsh environments, leading manufacturer of wireless modules AeroComm has released a very competitively priced 868 MHz spread spectrum wireless module. Aimed at OEMs producing equipment for worldwide markets, the module is a European version of the company's highly acclaimed and proven AC4490 900 MHz modules.
Designated the AC4486, the new transceiver module interfaces with OEMs' designs via serial TTL level connection, providing transparent, bi-directional communication in point-to-point, point-to-multipoint and multi-to-multi networks using AeroComm's proprietary RF232 transparent protocol.
RF232 sets a new standard in low-cost wireless communication by managing 'over the air' issues-overcoming interference and multipath problems, detecting errors in the data, addressing messages to individual radios, securing transmissions from eavesdropping, verifying link quality and more.
AC4486 provides OEMs with two channels; one operating at 5mW and 100% duty cycle for short range applications, the other at 500mW and 10% duty cycling for longer range deployment. Dual frequency bands are provided covering 902-928 MHz, and 868-870 MHz.
Showing industrial versatility, the transceivers will operate over the industrial temperature range of -40ºC to +80ºC and are agency approved for use in portable, mobile and fixed applications in Europe. Various antenna options are available including integrated, external or solder pads, and the modules feature adjustable receiver sensitivity from -85dB to -102dB depending on data throughput.
With a highly integrated chip solution, the modules operate from a 3.3V supply and measure a compact 48 x 42 x 5mm. They are the smallest of their type available, making them ideal for use in battery powered, portable applications.
For manufacturers already using modules from AeroComm's AC4424 2.4GHz family or AC4490 900 MHz family, the AC4486 offers socket compatibility, enabling OEMs to 'design once' and subsequently interchange 868 MHz, 900 MHz or 2.4GHz radios to increase performance and/or expand their markets where other frequency bands are not accepted.
The AC4486 provides an excellent alternative to the increasingly saturated 433 MHz band. AeroComm's high operating speed (up to 76,000 bps) is a dramatic improvement over commonly found '868' modules operating at 9600 bps.
The modules are aimed at OEMs who design and manufacture industrial or commercial products that currently use alternative methods of communication, such as infrared, serial/wired, memory card download, or other less sophisticated wireless means. AC4486 is suitable for a wide range of applications including vending machines, automated meter reading, gaming, electronic signs, wheel alignment, pool and spa control, point of sale, fleet management, lighting control and security.
Formed in 1990, AeroComm was the first manufacturer to gain FCC approval for 2.4 GHz direct sequence spread spectrum transceivers in 1994. Since then, the company has shipped over 100,000 wireless connectivity devices for home, small business and OEM markets. In 1996, AeroComm's technical focus became frequency-hopping due to its reduced cost, lower power consumption, higher interference immunity and smaller size. Today its proprietary methods of implementing spread spectrum technology enable wireless applications that were previously cost-prohibitive. The ConnexRF line offers a variety of standard OEM RF transceivers as well as custom solutions for major OEMs. An award-winning GoPrint line of printer sharing devices is also available via retail channels.
