II. Core Technical Features of the MAYA-W381-00B: Combining Low Power Consumption with High Performance
1. Wi-Fi 6/6E Technology: High Speed, High Efficiency, and Congestion Resistance
The MAYA-W381-00B module fully supports the Wi-Fi 6 (IEEE 802.11ax) and Wi-Fi 6E standards, covering operation across the 2.4GHz, 5GHz, and 6GHz tri-band spectrum. It can flexibly switch between frequency bands according to the signal environment of the IoT application scenario, adapting to connection requirements in different settings. In SISO mode, it supports operation at a 20MHz bandwidth and is compatible with MU-MIMO technology, enabling simultaneous communication between the access point and multiple devices. This significantly enhances network availability in densely populated environments and effectively resolves network congestion issues arising from the concentrated deployment of IoT devices.
The core advantages of Wi-Fi 6/6E lie in their efficiency and energy savings: utilising OFDMA (Orthogonal Frequency Division Multiple Access) technology, a single channel can be divided into multiple resource units, enabling simultaneous transmission across multiple devices, thereby improving network efficiency and reducing latency; Support for Target Wake Time (TWT) technology enables intelligent scheduling of device wake-up and sleep times, allowing modules to enter low-power mode when no data is being transmitted, thereby significantly reducing power consumption and meeting the long-lasting battery life requirements of IoT devices. Furthermore, the new 6GHz band introduced in Wi-Fi 6E provides more available channels and supports ultra-wide channels of up to 160MHz, effectively reducing signal interference. This delivers more stable connectivity for high-bandwidth, low-latency IoT applications, such as high-definition data transmission and real-time monitoring.
The module’s Wi-Fi output power reaches up to 18dBm (EIRP), and it supports operation as an access point, client, point-to-point device, or in hybrid modes. It is compatible with the full range of IEEE 802.11 b/g/n/a/ac/ax protocols and offers excellent backward compatibility, enabling seamless integration with existing Wi-Fi devices. It also supports Wi-Fi micro-access point connections for up to 12 devices, meeting the requirements of IoT applications involving multi-device collaboration.
