RF Evaluation and Development kits, such as the SDK-AC4790LR-200M, are designed to enable developers working in radio frequency (RF) technology fields to easily, quickly and reliably test, build and deploy continuously evolving wireless communication systems. The SDK-AC4790LR-200M is a fully integrated development platform for evaluating and prototyping Carrier-Sense Multiple Access/Collision Detection (CSMA/CD)-based applications for the 2.4GHz industrial, scientific and medical (ISM) band.

The SDK-AC4790LR-200M features a flexible hardware architecture that allows developers to adjust the core features and performance to match their specific needs. It can be used in single channel, dual channel or dual protocol configurations. The hardware includes a 200MHz system-on-chip (SoC) featuring 32 parallel processing channels, eight RF transceivers, 40-bit memory interface and two digital Signal Processors (DSPs). A Visual Simple Development Studio is also included to enable easy programming of the SDK-AC4790LR-200M\'s core features and performance.

The SDK-AC4790LR-200M\'s application field includes a wide range of industrial, consumer and medical products, such as wireless health monitoring devices, implantable medical care devices, industrial controllers, point-of-sale systems and consumer electronics products. The SDK-AC4790LR-200M can be used to evaluate, design and prototype radio-enabled systems for these and other applications.

The main work principle of the SDK-AC4790LR-200M is based on Carrier-Sense Multiple Access (CSMA) and Collision Detection (CD) techniques. CSMA and CD are used to detect and manage interference on the radio-frequency (RF) medium in order to ensure reliable and efficient communication between two or more communicating networks.

In the CSMA and CD process, a node in the wireless communication system sends out an RF signal on a shared medium. The receiving node monitors the received signal and determines if it is strong enough and reliable enough to be considered as a valid communication signal. If it is, then the receiving node takes control and proceeds with the communication process, otherwise the node retransmits until a valid communication signal is received.

Once a valid communication link is established between the nodes, the CD process is triggered. In order to enable successful data exchange between the nodes, the CD process is responsible for detecting and handling potential causes of interference, such as signal collisions and fading channels. If a signal collision occurs, the CD process quickly determines which node should abort the transmission and retransmit the data later. Likewise, if a fading channel is detected, the CD process is able to quickly change transmission channels in order to ensure that data is exchanged correctly and reliably.

To summarize, the SDK-AC4790LR-200M is a fully integrated development platform for precisely evaluating and prototyping carrier-sense multiple access/collision detection (CSMA/CD)-based applications for the 2.4GHz ISM band. The SDK-AC4790LR-200M can be used in applications that require reliable and efficient wireless communication, such as medical health monitors, implantable medical care devices, industrial controllers, POS systems, and consumer electronics products. Its main work principle lies in its adherence to the use of CSMA and CD techniques that enable it to both detect and manage interference on its shared medium in order to ensure faultless and efficient data exchange between two or more networks.
