Hardware Function Description
This chapter mainly describes the main hardware functions of this product, including
4G, WIFI/BT, audio, display,and charging.
4.1
WIFI/BT
The wireless module inside the tablet complies with IEEE 802.11 a/b/g/n/ac standard
and it can achieve up to a speed of 433.3Mbps with single stream in 802.11ac draft to
connect to the wireless LAN. The integrated module provides SDIO interface for Wi-Fi,
and UART interface for Bluetooth.
Features:
●
IEEE 802.11a/b/g/n/ac dual-band radio with virtual-simultaneous dual-band
operation.
●
Single-stream spatial multiplexing up to 433.3 Mbps data rate.
●
Supports 20, 40, 80 MHz channels with optional SGI(256 QAM modulation).
●
Supports Bluetooth V5.0+EDR with integrated PA for Class 1.5 and Low
Energy (BLE).
●
Concurrent Bluetooth, and WLAN operation.
●
Simultaneous BT/WLAN receive with single antenna.
●
Supports standard SDIO V3.0 and backward compatible with SDIO V2.0 host
interfaces.
-SDIO V3.0(4-bit)
— up to 208 MHz clock rate in SDR104 mode
●
BT host digital interface:
-UART (up to 4 Mbps)
●
IEEE Co-existence technologies are integrated die solution
●
ECI
—enhanced coexistence support: ability to coordinate BT SCO
transmissions around WLAN receives

Audio
VT-TAB07-RK68H has a 3.5mm Headphone jack, a 1.0W Speaker and a MIC. The
headphone jack supports drive-by-wire control and MIC function. If you want to use
both of these features, your headphones must support them, too. Our headphone
jack is compatible with three-section headphone and four-section headphone.
