Radicom’s RB4000 Features A Quick And Simple Solution For Wireless Point-To-Point Communications

These Modules Provide Fast Pairing And Allow Superior Performance In The Presence Of Interference From WiFi Wireless Devices

Radicom Research is shipping its RB4000 and RB4000HM Bluetooth modules for short-range wireless data connectivity. They are manufactured to fulfill OEM needs for embedded short-range communication in products. The low-cost modules act as RS232 cable replacement and offer an affordable, easy alternative for wireless point-to-point communication across distances up to 60 feet.

The RB4000 Series is a full Bluetooth system solution with an integrated controller, antenna, and Bluetooth transceiver that features Serial Port Profile (SPP). It utilizes the BlueCore4-External Chipset from CSR, who is the leader in Bluetooth chipsets. These Class 2 modules are Bluetooth V2.0 + EDR (Enhanced Data Rate) compliant for increased throughput, reduced battery consumption, and improved security. As a result, the RB4000 Series provide fast pairing and allow superior performance in the presence of interference from 802.11 (WiFi) wireless devices and other 2.4GHz radios.

“The RB4000 family’s low cost and reliable connectivity make it the ideal OEM solution for a number of industrial uses,” says Alex Tsau, Vice President of Operations at Radicom Research. “Our response from M2M providers has already been outstanding.”

They are designed for integration in barcode readers, medical devices, and other monitoring systems. The RB4000’s low power consumption and extreme operating temperatures that range from -40ºC to +85ºC provides flexibility across a number of industries and situations. With 8Mbits of flash memory onboard, OEM specific parameters can easily be uploaded for customized configuration. The RB4000HM-c module includes a U.FL connector that is built for flexible antenna placement for additional customization.

“Bluetooth data connectivity is more critical than ever when it comes to device flexibility,” says Tsau. “The RB4000 family makes this happen, all at an affordable price.”
