Wi-Fi 6, NearLink multi-mode IoT SoC
Not launched yet, release strategy undecided
The performance-enhanced chipset Hi3863EV100 supports 2.4 GHz radar-based human activity detection across a wide range of different scenarios, from home appliances to smart lighting and always-on IoT devices. It packs an IEEE 802.11 b/g/n/ax baseband and RF circuits, which include a power amplifier (PA), low noise amplifier (LNA), RF balun, antenna switch, and power management module.
With regard to Wi-Fi, the chipset supports 20 MHz frequency bandwidth and operates with a maximum physical layer bit rate of 114.7 Mbps, contributing to larger transmit power and better coverage.
In terms of NearLink, the chipset supports SLE 1 MHz, 2 MHz, and 4 MHz frequency bandwidths, compatible with SLE 1.0, and as an SLE gateway, it supports a maximum air interface rate of 12 Mbps.• Hi3863: 4 MB flash memory, Wi-Fi, SLE multi-mode concurrency, and single antenna channel

Wi-Fi 6 introduces OFDMA, spatial reuse (SR), and BSS Coloring to mitigate co-channel interference and upscale concurrent connections. Wi-Fi 6 supports higher-order modulation and smaller subcarriers to provide higher rates. Multi-user multiple-input multiple-output (MU-MIMO) technologies, coupled with a beamforming technique, enable APs to communicate with multiple devices simultaneously, thereby allowing for more concurrent connections and better coverage.
In addition to the standard Wi-Fi bands, the product also supports dynamic narrowband Wi-Fi bands. This means that, for scenarios where speed is not critical, the product can reduce the Wi-Fi spectrum bandwidth to provide better coverage.
With a novel physical layer, NearLink SLE supports smaller air interface timeslots, leading to greatly reduced end-to-end latency. Its polar code–based channel coding delivers over 7 dB coverage gains and anti-interference capabilities. It supports spectrum resource allocation based on center scheduling and uses an innovative channel scanning and selection mechanism. As such, it implements SLE fast frequency hopping and optimal channel selection, bringing great leaps in connectivity stability and transmission reliability. NearLink SLE also supports larger air interface bandwidth and higher-order modulation. Compared with traditional short-range technologies, SLE offers much higher air interface transmission rates.
The product can auto-discover NearLink devices within range; and complete device registration on the cloud through a secure and reliable communication channel.
Better yet, the product reports network configuration errors and guides the user through troubleshooting steps, so as to reduce return and replacement caused by network configuration failures. Collection of network configuration exception data helps with informed improvements.
By sending out and then receiving radio waves, the radar sensor is able to detect static and dynamic human activity within a range. Informed by the detection results, apps of smart home appliances can provide smart, activity-aware services, for example, turning on or off the screen based on whether the user is detected.
To meet diverse needs, the range and sensitivity of detection are both customizable.
