What is HaLow?

Wi-Fi HaLow is the designation for products incorporating IEEE 802.11ah technology. It augments Wi-Fi by operating in spectrum below one gigahertz (GHz) to offer longer range and lower power connectivity. Wi-Fi HaLow meets unique requirements for Internet of Things (IoT) to enable a variety of use cases in industrial, agricultural, smart building, and smart city environments.

Wi-Fi HaLow enables the low power connectivity necessary for applications including sensor networks and wearables. Its range is longer than many other IoT technology options. It provides a more robust connection in challenging environments whereby ability to penetrate walls or other barriers is an important consideration.

LoRa/ HaLow/ Sigfox Frequency: 915 MHz.

To achieve IoT communications which should ideally be long range and low-power, new energy efficient communication technologies are emerging that target devices with low energy requirements. Examples of such communication technology solutions include LoRa, HaLow and Sigfox. These solutions are cheaper compared to conventional cellular network solutions in terms of operational cost for providing a low-power interface to sensors for data communication.

IoT communications should ideally be:

  • Low power.
  • Low cost.
  • High number of connections.
  • Long battery life.
  • Long range.
  • Low bitrate.
  • Low storage capacity.
  • Low processing capacity.
  • Small size devices.
  • Simple network protocols and architecture.
  • Relaxed latency.

LoRa.

LoRa is a Low Power Wide Area Network (LPWAN) based wireless technology that is managed by the LoRa Alliance. LPWAN is used for long range communications in Wireless Sensor Networks. Its standard supports the IEEE802.15.4 communication standard. As LoRa technology does not require line-of-sight, it is a suitable candidate for both urban and rural locations. LoRa technology is established on a technology known as LoRaWAN, which is based on the pure ALOHA scheme.

LoRa Characteristics:

  • High Sensitivity (Gateways: up to -142 dBm, End Nodes: Up to -137 dBm).
  • LoRa modulation: A typical channel bandwidth of 125 KHz using a version of Chirp Spread Spectrum (CSS).
  • Strong indoor penetration: up to 20dB penetration (deep indoor) with high spreading factor.
  • Long range communication (up to 15 Km).
  • Resistant to signal weakening, multi-path and Doppler Effect.
  • Robust to channel noise due to it occupying the whole channel bandwidth to broadcast a signal.

HaLow.

Devices using IEEE802.11ah can cover a range of about two hundred meters to a few kilometers. To improve on the energy consumption rate of the IEEE 802.11ah solution further, the Wi-Fi working group has recently introduced a low-power solution, Wi-Fi HaLow, into the standard.

Wi-Fi HaLow operates in the spectrum lower than one GHz to offer lower power and longer range connectivity, thus augmenting Wi-Fi. Wi-Fi HaLow meets many of the IoT (Internet of Things) unique requirements to allow various use cases in agricultural, industrial, smart city and smart building environments.

Wi-Fi HaLow enables the low power connectivity required for applications including wearables and sensor networks. It provides a connection that is more robust in difficult environments where it is important to penetrate walls and other barriers, and its range is longer than many other IoT technology options.

Sigfox.

Sigfox is managed as a proprietary network and is low-power wireless technology that can be used to implement long range end-to-end communications. It supports the IEEE 802.15.4 communication standard. Sigfox employs an UNB scheme at the PHY layer. Due to the shortcomings of commonly used MAC schemes, Sigfox uses the ALOHA scheme, which provides a random communication channel access service at the MAC layer. A random FDMA (RFDMA) scheme may also be employed as a Sigfox network MAC layer. Sigfox technology is suitable for line-of-sight transmission of small amounts of data using the free-license ISM RF in sub 1 GHz ranges like 915 MHz and 868 MHz. Sigfox devices transmit at a data rate of 100 bits per second.

Sigfox Characteristics.

  • Proprietary system.
  • The physical layer based on an Ultra-Narrow band wireless modulation.
  • Low power.
  • Low throughput (100 bps).
  • 140 messages per day, per device.
  • Extended range (up to 50 km).
  • Cloud platform with Sigfox –defined API for server access.
  • Subscription-based model.
  • Roaming capabilities.

Warning

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

Please note: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
