GS1011：Ultra Low-Power Wireless Single Chip
GS1011 device is a highly integrated ultra low power wireless single chip which contains an 802.11 radio, media access controller (MAC) and baseband processor, on-chip flash memory and SRAM, and an applications processor all on a single package. The GS1011 supports the full 802.11b (11Mbps) data rates providing scalability on data throughput for higher bandwidth application while still providing the ultra low power consumption for years of battery life. The GS1011 is pin and package compatible with the GS1010 enabling seamless hardware upgrade for current designs. Along with its embedded software stack it offers a highly scalable, reliable, manageable and secure wireless link to meet the growing demand of wireless sensor networks utilizing the broadly accepted IEEE 802.11 standards infrastructure. This solution is ideal for use in smart energy, building automation, industrial and commercial automation and cold storage monitoring applications. In addition, the solution provides capabilities such as location awareness which also make it well suited for logistics and supply chain applications for tracking asset
location and status.
