- 2. Learning objectives At theend of this chapter, student should be able to: 1. Determine wired and wireless connectivity. 2. List type of wired connectivity and wireless connectivity
- 4. Type of connectivity Wired•Serial bus, USB, Ethernet Wireless •NFC, Short range connectivity, cellular, LPWA, Satellite
- 5. Near Field Communication ➢NFC is very short-range communication protocol ➢ Point-to-point communication ➢ Needs both devices within field to communicate ➢ Contactless payments (apple pay, android pay, PayPal etc.) ➢ Ticket validations (Oyster) ➢ File sharing › Multiplayer gaming ➢ Most smartphones are NFC ready
- 6. Bluetooth ▪ Short rangecommunication ▪ Transmission at the ISM band ▪ Low transmission power, Low penetration properties (walls, doors, windows etc) ▪ High transmission rate, High ▪ Low cost
- 7. Zigbee ▪ Wider rangecommunication ▪ Transmission at the ISM band ▪ Low transmission power ▪ High transmission rate ▪ Support many nodes
- 8. Wi-Fi ❑ Short rangecommunication ❑ Transmission at the ISM Band ❑ Low transmission power ❑ High transmission rate ❑ support many nodes (WLAN)
