Study Notes

Wired vs Wireless Monitoring

Wired systems have limitations with installation, scalability, and access to real-time data.
Wireless monitoring offers flexibility, cost-efficiency, and real-time access to data.

Need for Wireless Monitoring

Healthcare: Continuous patient health monitoring, detecting anomalies in vital signs, and managing chronic conditions.
General: Enables real-time data transmission for applications like environmental monitoring and industrial automation.
Other: Enables long operation on battery power, high scalability, and cost-effective deployment.

Body Area Network (BAN)

Definition: A specialized wireless network designed to monitor and transmit physiological data from or around the human body.
Components:
- Body Sensor Units (BSUs): Small sensors worn or implanted to monitor vital signs.
- Body Central Unit (BCU): Collects data from BSUs and processes it for analysis and transmission.
- Communication Protocols: Utilize Bluetooth, Zigbee, and other low-power wireless technologies.

BAN and Healthcare

Healthcare Monitoring:
- Chronic disease management with real-time monitoring for timely interventions.
- Early detection of health issues like potential heart attacks.
Telemedicine: Enables remote patient monitoring without physical visits.
Sports & Fitness: Helps track performance metrics during training for optimized routines.
Personal Safety & Assistance: Provides real-time health monitoring and alerts for individuals with disabilities.

Benefits of BAN

Real-Time Data Collection: Enables immediate responses to critical health changes.
Cost Efficiency: Reduces hospital visits by facilitating remote monitoring.
Improved Quality of Life: Empowers patients to manage their health effectively from home.

Technical Challenges of BAN

Security and Privacy: Ensuring data confidentiality and integrity with robust encryption and communication protocols.
- Protecting against unauthorized access.
- Addressing interoperability risks between different devices with various communication standards.
Reliability:
- Maintaining reliable connections in environments with many wireless devices, mitigating signal interference.
- Ensuring network scalability as new devices are added.

BAN Architecture

Component Breakdown:
- Sensor Nodes: Wearable or implantable sensors.
- Coordination Node (CCU): Central unit that collects data from sensors and processes it.
- Communication Technologies: Utilize protocols like Bluetooth, ZigBee, Wi-Fi, and Ultra-Wideband (UWB).
Communication Layers: Three-tiered model for data transfer.
- Intra-BAN Communication: Data transfer between sensor nodes.
- Inter-BAN Communication: Data transfer from the BAN to external devices.
- Beyond-BAN Communication: Transmitting data over the internet to healthcare systems.

Different Modes of Wireless Communication

Radio Communication: Data transmission using radio waves, commonly found in broadcasting and two-way communication systems.
Satellite Communication: Relaying signals via satellites for long distances, crucial for GPS and global broadcasting.
Cellular Communication: Using a network of cell towers for mobile phone services.

Microwave Communication: Long-distance transmissions via microwave signals.
Infrared Communication: Short-range communication using infrared light, found in remote controls.
Zigbee and RFID: Specialized protocols for short-distance wireless communication, often used in IoT applications.

Wireless Communication Techniques

Modulation and Demodulation: Converting information into signals suitable for radio waves and vice versa for long-distance transmission.
Diversity Techniques: Enhancing signal reliability by using multiple transmission paths or antennas to combat fading effects:
- Antenna Diversity: Using multiple antennas for signal reception.
- Frequency Diversity: Transmitting the same signal over different frequencies.
- Time Diversity: Transmitting repeated signals at different time intervals.
Equalization: Compensating for channel impairments in receivers to improve signal clarity.
