Signal Strength Roaming
Satellite Network Mesh Network
Ad Hoc Network NFC
Wifi Router

 

The ability for a mobile device to maintain connectivity while moving between different wireless networks or cells. The power level of a wireless signal, indicating the quality of communication between devices.
A decentralized wireless network where each node cooperates to distribute network data, often used for increased coverage and improved reliability. A wireless network that uses satellites to provide coverage over large geographic areas, often used for communication in remote locations.
A very short-range wireless technology that enables communication between devices by bringing them close together. A temporary and spontaneous wireless network formed between devices for a specific purpose without the need for a central infrastructure.
a device that forwards data packets between computer networks a wireless networking technology that allows devices to connect to the internet via a router

Cracking Internet Of Things
Sensors Smart Home
Security NAT
Private IP Public IP

 

A network connecting physical objects with sensors and software to collect and exchange data. The act of defeating network encryption to gain unauthorized access to data or systems.
A residence with connected devices and systems controlled remotely to improve comfort, convenience, and energy efficiency. Devices that detect physical or environmental input such as temperature, pressure, motion, or light, and convert it into an electrical signal.
A process where a router or firewall modifies a packet's source IP address to another IP address. The measures taken to protect connected devices, networks, and data from unauthorized access, data breaches, or other cyber threats.
A public IP address is an IP address that is used to identify a device on the public internet. An IP address used inside a local network that cannot be accessed directly from the internet.
