GOODOCOM Technologies Confidential GOC-BA440 Specification
GOODOCOM Technologies Confidential 4
1. Introduction
In IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–MCS9 (up to 256 QAM) in
20 MHz, 40 MHz, and 80 MHz channels for data rates of up to 433.3 Mbps. All rates specified in the
IEEE 802.11a/b/g/n are supported. Included on-chip are 2.4 GHz and 5 GHz transmit amplifiers and
receive low-noise amplifiers. Optional external PAs and LNAs are also supported.
The WLAN section supports the following host interface options: an SDIO v3.0 interface that can
operate in 4b or 1b mode, a high-speed 4-wire UART, and a PCIe Gen1 (3.0 compliant) interface. The
Bluetooth section supports a high-speed 4-wire UART interface.
Using advanced design techniques and process technology to reduce active and idle power, theGOC-
BA440 is designed to address the needs of mobile devices that require minimal power consumption and
compact size. It includes a power management unit which simplifies the system power topology and
allows for direct operation from a mobile platform battery while maximizing battery life.
The GOC-BA440 implements highly sophisticated enhanced collaborative coexistence hardware
mechanisms and algorithms, which ensure that WLAN and Bluetooth collaboration is optimized for
maximum performance. In addition, coexistence support for external radios (such as LTE cellular and
GPS) is provided via an external interface. As a result, enhanced overall quality for simultaneous voice,
video, and data transmission on a handheld system is achieved.
