1. Introduction
AMPAK Technology likes to announce a low-cost and low-power consumption
module which has Wi-Fi 802.11b/g/n functionalities. The highly integrated
WSDB-750GN module makes the possibilities of web browsing, all types of
battery powered device. With seamless roaming capabilities and advanced
security, WSDB-750GN can also interact with different vendors’ 802.11b/g/n
Access Points in the wireless LAN.
The wireless module complies with IEEE 802.11 b/g/n standard and it can
achieve up to a speed of 72.2Mbps with single stream in 802.11n draft 7.0,
54Mbps as specified in IEEE 802.11g, or 11Mbps for IEEE 802.11b to connect
to the wireless LAN.
This compact module is a total solution for a combination of Wi-Fi 802.11b/g/n
technologies with Microcontroller Processor. The module is specifically
developed for embedded system devices.
