Energy Efficiency
?802.11ah protocols promote conservation of energy for devices that can sleep for long periods of time. Enables widest range of power options from coin cell batteries for short reach applications to larger battery higher-power options to reach up to 1 km. Sub-1 GHz signals travel farther with less energy than 2.4 GHz signals. Transfers more bits per unit of energy than other technologies.

Idle Power Consumption
?802.11ah idle and sleep modes, combined with Morse Micro’s proprietary circuit design techniques offer low idle power consumption to rival other technologies.
Data Rate
?802.11ah offers widest range of data rates to suit IoT. From high definition cameras to lower bit rate temperature sensors or door locks. Rates can automatically adjust for changes in conditions or distance from the AP, just like Wi-Fi.

?1 meter to 1 km, Sub-1 GHz narrow band signals of 802.11ah cover a wider range of applications from smart homes to large warehouses, without repeaters or meshes. Reaches 10x-100x farther than 2.4 GHz Wi-Fi or Bluetooth.

Penetration through material
?802.11ah uses Sub-1 GHz RF signals to penetrate through walls and objects better than higher frequencies such as 2.4 GHz Bluetooth, Wi-Fi or Zigbee. Variability of construction materials and layouts of homes and buildings has less effect on Wi-Fi HaLow signals. Single AP solutions with higher out-of-box installation success without requiring meshes or repeaters that would cause congestion, increase latency, or reduce throughput.
?Wi-Fi HaLow requires WPA3 and higher levels of security for authentication and encryption of data. Morse Micro supports existing WPA3 and future improvements in Wi-Fi security, as well as unique optional features for secure boot. High data rates of 802.11ah enable fast over-the-air (OTA) firmware updates, which many long-range wireless technologies like LoRa or Sigfox cannot accomplish without taking devices offline for long periods of time.
Network Data Capacity
?802.11ah specifies a wide range of data rates for up to 8,191 devices per AP. Multiple signaling options reduce overhead required to manage and control devices. This reduces collisions and frees up airwaves for active devices to transfer more data at the fastest MCS rates they can achieve.
Installation/ Operational Costs
?IEEE 802.11ah Wi-Fi HaLow supports native IP traffic, just like traditional Wi-Fi. Simple installation requires only a Wi-Fi HaLow capable AP or Router. No proprietary hubs or gateways. Star-oriented architecture of HaLow does not require complex meshes of repeaters that bog down messages and cause management problems for other wireless technologies. Wi-Fi HaLow uses license free sub-1 GHz spectrum; no recurring subscription fees or data plans need to be paid to any cellular network providers.
Service Provider contract
?No contract is required since 802.11ah Wi-Fi HaLow does not rely on mobile service providers. Customers own their equipment and use license free radio spectrum. Just like Wi-Fi.
Licensed Spectrum
?IEEE 802.11ah Wi-Fi HaLow operates in the license-exempt frequency bands worldwide, ranging from 750 MHz to 950 MHz . It does not use the frequencies of cellular data carriers that usually bear a cost of license fees and subscriptions. Certain restrictions of use may apply and may vary by country in which Wi-Fi HaLow operates.
?IEEE 802.11ah is a globally recognized standard which defines how Wi-Fi HaLow devices communicate. Much like previous generations of Wi-Fi, Wi-Fi HaLow equipment vendors can ensure they will interoperate by following the guidance of the Wi-Fi Alliance ( Wi-Fi Alliance provides specifications, guidance and certification services to members. Other wireless IoT technologies are either proprietary or do not have as well-organized guidance. Wi-Fi HaLow users will experience the same ease of use as traditional Wi-Fi networks.

Native IP support
?Native support for IP traffic is defined in IEEE 802.11ah, much like traditional Wi-Fi. Using a Wi-Fi HaLow capable router, all clients devices can use IPv4/IPv6 transport protocols for direct access to the internet for cloud-based services and management of IoT data. Other wireless IoT technologies such as Bluetooth, Zigbee, Z-Wave, LoRa and Sigfox require a proprietary gateway to convert all local client traffic to IP traffic for internet access. Their extra stages of packet processing are required to wrap extra data around the packets, adding delays and reducing efficiency of their networks.
