Key Features
802.11ah Wi-Fi HaLow
Wi-Fi HaLow is an optimized Wi-Fi solution for Internet of Things (IoT) devices. Operating in the Sub 1GHz license-exempt band offers a greater coverage range. HaLow's power-saving mechanisms like a longer sleep time greatly reduces power consumption and hence increase battery life. This novel technology is designed to reduce collisions and support up to 8.191 stations efficiently. Wi-Fi HaLow HA92 Class modules enable a variety of new power-efficient use cases in the Smart Home, connected car, digital healthcare, wide area-based sensor networks, sensor backhaul system, potential Wi-Fi off-loading, as well as industrial, retail, agriculture, and Smart City environments.
ISM bands utilization below 1GHz
802.11ah HaLow is a Wi-Fi standard that has been designed to utilise the Sub-1GHz licence free ISM bands. The radio propagation at these frequencies means that the signals are able to travel greater distances and this opens up opportunities for uses with the IoT where sensors and control nodes may be located further apart. To accommodate the different aspects of Sub-1GHz Wi-Fi a new physical layer and MAC has been developed to enable communications in these frequencies. The IEEE 802.11ah standard is aimed at providing a global Wireless LAN, WLAN standard that operates within the unlicensed ISM, Industrial, Scientific, and Medical, bands that are available below 1GHz.
The Internet of Things (IoT) challenge
In recent years a collection of new terms have been coined in an attempt to clarify the new scenario of connected applications and devices: the Internet of Everything (IoE) appears as a concept that contains both the IoT and the Internet of Humans (IoH), including the capability to share data between each other or among themselves using machine to machine (M2M) or machine to human (M2H) communications. Following a similar approach, we shape the IoT definition to include two different concepts: industrial IoT (iIoT) and consumer IoT (cIoT), exhibiting a new scenario that will dominate the world’s communications in the near future, at least in terms of number of participating devices.
Built-in meshing technology
Through the HaLow's built-in meshing technology, any IoT network node can be set as a reference node. A well-spread distribution of reference nodes is likely to provide a better location accuracy than a network with few reference nodes all placed in the same direction from the device to be located. In a mesh IoT topology, nodes can exchange messages between each other and are much less susceptible to single points of failure. If a link fault occurs, the device can look for any other neighbor to connect to. Thus, mesh IoT networks provide better coverage and offer better positioning accuracy than star networks.
Industrial Temperature Grade
Built with end quality components from the multi-layered PCB to the front end high-quality RF, the modules qualify through industrial grade operating temperature ranges from -40°C to +85° Celsius, storage temperature from -50°C to +90°C, non-condensing operating humidity from 10% to 90% and storage humidity 5% to 90%. They are highly integrated wireless modules, perfectly suitable for demanding or mission-critical applications in the military, aerospace, transportation, energy and industrial automation markets. The modules can constantly been exposed to extreme external and internal conditions such as wide temperature variances, system start-up in low/high temperature, severe humidity, dust and other environmental circumstances whithout performance losses.
Less Power
HaLow’s new sophisticated channel access mechanism called Restricted Access Window (RAW) reduces energy consumption — an important performance indicator for 802.11ah — since the stations can sleep almost always except for the allocated time intervals. HA92 Class requires a fraction of the power of a conventional Wi-Fi module. Low peak power requirements enable the use of small batteries which can last many years. Also other new features introduced by 802.11ah achieve more efficient transmissions, thus allowing energy savings: the reduced overhead due to shorter headers and mechanisms such as the implicit acknowledgement, and the speed frame exchange, which is a method that allows to exchange a bidirectional sequence of frames during a reserved Transmit Opportunity (TXOP).
Form Factors and Frequency Diversification
The Class Modules are available in various Form Factors with a unique certification and support, meeting the needs for different designs and diverse application areas. They are flexibly designed to operate within the regionally available unlicensed Sub-1GHz ISM, Industrial, Scientific, and Medical, bands. In this way HA92 allows Wi-Fi-enabled devices to gain access for short-term transmissions in these frequency bands that are currently much less congested.It comprises a total of 5 model variants by each form factor (China, Europe, Japan, Korea and USA) which are making it a gamut of choice for designing demanding IoT applications.
Coverage Range
IoT applications require frequently more than 1 km of coverage for their desired operation. Besides the fact that 802.11ah is using Sub-1GHz frequency band with better propagation characteristics, the extended range requirement is fulfilled by introducing 1 MHz wide transmission and by using a new Modulation and Coding Scheme (MCS) index (MCS10). Along with 1 MHz channel bandwidth, HA92 also supports 2, 4, 8 and 16 MHz. These narrower bandwidths entail a larger symbol duration than other Wi-Fi specifications. With longer symbols and guard intervals, HA92 transmissions are more robust to inter-symbol interference found in longer links and outdoor scenarios. By supporting Multiple-Input Multiple-Output (MIMO), HA92 also benefits from spatial diversity, which improves the received signal quality and, hence, makes longer links possible. Multi-hop operation with relays or mesh networking to extend coverage are also built-in.
World Certifications
Pre-certifications are existing for all variants and major domains (FCC, EU RED, Japan, Korea, China). Optionally we offer co-sponsoring for further countries as well as in house support and assistance with regulatory, antenna and design. Through the module certifications and our extensive experience with certification authorities and labs, we are able also to help partners and customers certify their devices globally and source them in any part of the world.
