2022-11-24/ By Admin

SKYLAB is committed to GNSS, WiFi, Bluetooth, UWB and other wireless product manufacturers. SKYLAB can provide wireless video relay solutions based on WiFi technology. It is based on MT7628N WiFi module SKW92A with integrated 2MP HD camera function. This solution can meet the needs of video relay in different industries such as the Internet of Things, smart campus, smart home, and smart factory.

During the upgrade process of the Internet of Things, a higher resolution video source requirement is put forward for wireless transmission. The existing WiFi module cannot satisfy the wireless relay of high-definition video. The wireless video relay solution can effectively solve the problems of non-line-of-sight, large delay, and instability.

Wireless video relay WiFi module solution introduction

Wireless video relay WiFi module solution introduction

(1)Program composition

The wireless video relay solution consists of a USB camera, AP/Router WiFi module SKW92A, SKW92 Demo board and computer.

(2)Working principle

The user builds a local video collection and transmission environment through two WiFi modules SKW92A, SKW92 Demo board, USB camera, and computer. The WiFi module captures the video content of the USB camera. It connects to the hotspot through another WiFi module and accesses IP to realize wireless video relay.

(3)Camera connection method

The WiFi module SKW92A supports the camera type as a USB free drive camera. It is driven by UVC, and the driver-free camera is connected to the WiFi module SKW92A through USB. Then it realizes wireless video transmission;

WiFi module SKW92A supports wireless high-definition video transmission, up to 1920x1080 resolution, 30 frame rate.

(4)Supported systems

(1) WinXP/Vista/Win7/Win8

(2) Linux with UVC (above linux-2.6.26)

(3) MAC-OS X 10.4.8 or later

(4)Wince with UVC

(5) Android 4.0 or above with UVC

Introduction of MT7628N WiFi module SKW92A

(1) This module is developed based on the MT7628N solution. It integrates 802.11n MAC and baseband. 1 2.4GHz wireless broadcasting equipment and front-end module, 1 580MHz MIPS CPU, 1 high-speed Ethernet PHY. It only needs to provide 3.3V power supply externally when working.

(2) The module conforms to the 802.11n Wi-Fi standard, 2x2 MIMO dual receiving and dual transmitting. Under the 802.11n Wi-Fi standard, a bandwidth of 20MHz can reach a data transmission speed of 144Mbps. 40MHZ bandwidth can reach 300Mbps data transmission speed.

(3) SKW92A supports five working modes: Bridge mode, Gateway mode, AP/Client mode, Router mode, and 3G/4G Router mode.

(4) It can be applied to USB wifi camera, IoT, Wi-Fi AP and 3G/4G WiFi router, etc.
