Order: Pieces. Start Order Contact Supplier. Order : Buy Samples. Product Details. Company Profile. Quick Details. Model Number: Ra Online Customization. Product Description. Great for IoT applications to send sensor data to the cloud over long ranges. Any devices that are interconnected through a standard RS interface and cable at ProxLink is a wireless replacement for the RS cable.

Multiple ProxLinks can be operated simultaneously in the same facility. ProxLink key features include: Wireless communication for standard RS interfaces Resistant to interference and noise from other devices operating in the band Range up to ft.

Using spread spectrum technology, the ProxLink provides robust, interference resistant operation which penetrates through walls and other obstructions. ProxLink offers a working range of up to feet. The actual range may vary due to differences in physical operating environments. Spread spectrum technology allows use of these products without a FCC site license. Proxim has certified these products for use as unlicensed spread spectrum devices with the FCC.

This is called as frequency reuse. The frequencies of the data are hopped from one to another in order to provide a secure transmission. The amount of time spent on each frequency hop is called as Dwell time. Whenever a user wants to send data using this DSSS technique, each and every bit of the user data is multiplied by a secret code, called as chipping code.

This chipping code is nothing but the spreading code which is multiplied with the original message and transmitted. The receiver uses the same code to retrieve the original message. Both the spread spectrum techniques are popular for their characteristics.

To have a clear understanding, let us take a look at their comparisons. Although spread spectrum techniques were originally designed for military uses, they are now being used widely for commercial purpose. Gowthami Swarna. Asif Hussain. John Shea.
