Working Principle

2000826-3 operates according to the IEEE 802.11 standard, which defines the physical and media access control layers for WLANs. It operates in two frequency bands: 2.4 GHz and 5 GHz. In the 2.4 GHz band, there are 11 channels, while in the 5 GHz band there are 45 channels. The channels operate in the range of 2.4 GHz to 2.484 GHz, and 5 GHz to 5.825 GHz, respectively. The IEEE 802.11 standard also specifies the data transmission speed capabilities, which range from 54 Mbps to 600 Mbps.

At the physical layer, 2000826-3 operates using Orthogonal Frequency Division Multiplexing (OFDM) technique. This technique utilizes multiple subcarriers at different frequencies to allow parallel data transmission. At the media access layer, 2000826-3 utilizes the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol. This protocol ensures that only one device can transmit data at a time by listening the channel before transmitting, and allows multiple devices to communicate without interference.

Finally, at the link layer, 2000826-3 uses the Wireless Distribution System (WDS) protocol to provide a secure and reliable connection between multiple devices. This system allows multiple devices to communicate with each other in a mesh network, sharing the same frequency and data transmission power setting. Additionally, 2000826-3 also has the ability to provide Quality of Service (QoS) support, ensuring that time-sensitive data is transmitted with minimal delay or interruption.
