Wi-Fi HaLow
Wi-Fi HaLow, which is currently under development in the Wi-Fi Alliance, operates in sub 1GHz ISM band. Wi-Fi
HaLow is based on IEEE 802.11ah which provides longer range, lower power operation, and lower throughput
compared to other Wi-Fi technologies and hence is suitable for sensors and IOT devices distributed in larger
areas. Non harmonized spectrum is globally identified as a contributing factor for slow adoption of Wi-Fi
HaLow in the industry.

IEEE 802.11p
IEEE 802.11p defines enhancements to Wi-Fi required to support Intelligent Transportation Systems (ITS). IEEE
802.11p operates in 5.9GHz band. IEEE 802.11p enables delivery of high throughput data with low latency
which is required for ITS safety applications.

3) Long Range
The Wide Area Networks (WAN) operating in unlicensed bands primarily target IOT applications.
These technologies are also managed and are in direct competition with their licensed counterparts,
i.e., Cellular IOT solutions.
LP-WAN provides a detailed comparison of the following unlicensed Low Power Wide Area Networks
(LP-WAN) technologies:
LoRa:

The LoRa Alliance is driving the adoption of the LoRAWAN protocol that has been optimized for low cost, low
power, battery powered IoT devices that leverage a Chirp Spread Spectrum based physical layer.
SigFox:

Using an Ultra Narrow Band physical layer, the SIGFOX system is designed for infrequent sending of small
messages that characterizes many IoT use cases.

Wi-SUN:
The Wi-SUN Alliance promotes open interoperable standards for Smart Utility Networks based on peer-to-peer
and wireless mesh based IEEE 802.15.4g networks.

5.3.2 Alternative Licensed Access Technologies

The licensed access technologies addressing IOT are identified here. These technologies operate by sharing
spectrum with LTE and GSM networks that provide other data and voice services.

LTE-M
Standardized by 3GPP is an evolution of LTE optimized for IoT, focusing on M2M applications. Looks for
applications of large volumes of transactions with low data rate, with low cost devices and long battery life.

Narrowband IoT (NB‑IoT)
Standardized by 3GPP can be deployed over an existing infrastructure, with minor updates, of a normal 3G/LTE
carrier and can also be used “standalone” to enable deployments in dedicated spectrum. Focus of this
technology are an indoor coverage, low cost, long battery life and large number of devices.
