The layer at which each creates device connectivity is the primary distinction between IoT and WoT. IoT here just addresses the network layer between the devices. This means that each gadget has a transport medium for communication.
WoT aims to integrate them into the Web, whereas IoT focuses on building a network of things, systems, people, objects, and applications. Technically, WoT can be viewed as a flavor or choice of an application layer that has been overlaid over the network layer of the IoT.
I2C is better suited for communication with a large number of peripherals as well as situations involving dynamic switching of the principal device role among peripherals over the I2C bus, whereas SPI is preferable for high speed and low power applications.
The RPL protocol, sometimes known as cognitive RPL, is extended by the CORPL protocol. This network protocol uses the DODAG architecture and is intended for cognitive networks. The RPL protocol is changed in two new ways by the CORPL protocol. When a packet needs to be forwarded between two nodes, it uses opportunistic forwarding.
A PAN transported over a low-powered, short-distance wireless network technology, such as IrDA, Wireless USB, Bluetooth, or ZigBee, is known as a wireless personal area network (WPAN). A WPAN's range might be anything from a few millimeters to a few meters.
The RSSI minimum value for LoRa is -120 dBm. RSSI=-30dBm indicates a strong signal. RSSI=-120dBm indicates a weak signal.
Received Signal Strength Indicator is known as RSSI. Referencing Signal Received Power, or RSRP. Referencing Signal Received Quality, or RSRQ. SINR is an acronym for signal to noise ratio.
The 915 MHz frequency is designated for use by this technology in North America, hence 915 MHz antennas are frequently connected to LoRa in the US market.
A networking standard for inexpensive, low-power wireless control and monitoring systems is called Zigbee®. Zigbee is a self-healing, secure, and reliable mesh protocol that can expand to hundreds of nodes over wide areas. It was developed on top of the IEEE® 802.15. 4 radio.
LR devices can typically be elevated by mounting them on roofs or at higher heights to increase their broadcast range. Other elements, like - you guessed it - antenna characteristics, can also have a big impact on transmission range.
