Overview
WiFi HaLow adapts the familiar WiFi standard to a frequency and connection style that is ideally suited to the Internet of Everything.
Operating in the sub gigahertz range, this standard delivers 1 km range in point-to-point links and > 1km in 2-hop relays. By using a token-ring style of client management, a single HaLow access point can completely support up to 8191 clients, and provides adaptive bandwidth to each client based on their identified data transport needs.
The Aegis-IP 802.11 ah core is a complete digital platform implementing the MAC and Baseband layers of this protocol. The core is available in one of three major configurations: as a low power sensor node; as a full featured sensor node, and as an access point.
The Aegis 802.11 ah cores all include a bus master AXI interface to provide maximum throughput with minimal process intervention, and a processor core with additional bandwidth to host your application. When combined with a suitable radio from one of our partners, this core gives you everything you need to enable your products to join the Internet of Everything.
A typical customer application, depcited below, includes a suitable processor core where the Media Access Controller upper firmware (UMAC) resides, as well as the customer application.
Typical ApplicationThe Power Management Unit (PMU) wakes up and shuts down the core as an integral part of the low power operation, enabling sensor nodes to run up to three years on a single charge.
The integrated DMA engine, and the Lower Mac (LMAC) offload processing task from the processor core, further saving power.
The BaseBand (BB) provides all of the forward error correction, digital to analog conversion, data recovery and error correction features in very efficient hardware; and interfaces to the supported radio cores (RF).
The System RAM and System ROM are accessble from the AXI4 bus, as well as a set of timers and general interface engines.
Coded in System C and built with the Cadence HLS and Virtual Platform tools, user customization is readily available.
