2. Wireless mesh network - Wikipedia

   en.wikipedia.org/wiki/Wireless_mesh_network

   A wireless mesh network ( WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network. [1] A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent.

3. Z-Wave - Wikipedia

   en.wikipedia.org/wiki/Z-Wave

   Z-Wave. Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device, [2] allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks ...

4. IEEE 802.15.4 - Wikipedia

   en.wikipedia.org/wiki/IEEE_802.15.4

   IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.

5. Zigbee - Wikipedia

   en.wikipedia.org/wiki/Zigbee

   Zigbee is an IEEE 802.15.4 -based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.

6. Cognitive radio - Wikipedia

   en.wikipedia.org/wiki/Cognitive_radio

   Cognitive-radio networks aim to use the spectrum in a dynamic manner by allowing radio terminals to operate in the best available frequency band, maintaining seamless communication requirements during transitions to better spectrum. Spectrum sharing [9]: Spectrum sharing cognitive radio networks allow cognitive radio users to share the spectrum ...

7. LoRa - Wikipedia

   en.wikipedia.org/wiki/LoRa

   Physical range. >10 kilometres (6.2 mi) in perfect conditions. LoRa (from "long range") is a physical proprietary radio communication technique. [1] It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. [2] It was developed by Cycleo, a company of Grenoble, France, and patented in 2014. [3]
