Study Notes
PHY Layer Responsibilities
- Responsible for data transmission in IoT; true statement.
- Functions as the physical medium for data transfer between devices.
Communication Medium Access
- Managed by the MAC (Media Access Control) layer, which regulates device communication over a network.
Common Technologies in PHY Layer
- Zigbee is frequently employed for wireless communication in the PHY layer, facilitating low-power, short-range data transmission.
Understanding MTC in IoT
- MTC stands for Machine-Type Communication, which involves devices communicating autonomously without human intervention.
MAC Layer Access Control Method
- CSMA (Carrier Sense Multiple Access) is an access control method used in the MAC layer to manage how devices access the communication medium.
Collision Prevention in MAC Layer
- The MAC layer helps avoid collisions, ensuring simultaneous data transmission does not lead to data loss.
Massive MTC (mMTC) Capabilities
- mMTC is designed to support large numbers of devices in the IoT ecosystem, making it crucial for scalability.
PHY Layer Challenges
- Key challenge includes signal interference, which can impact performance and reliability of wireless communications.
Role of Third-Party Protocols (3PP) in IoT
- Primarily used for interoperability, enabling seamless integration and communication between diverse systems and protocols.
MAC Layer Key Technologies
- TDMA (Time Division Multiple Access) is a significant technology associated with the MAC layer, allowing multiple users to share the same frequency channel by dividing the signal into time slots.
