At the end 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 range communication
▪ Transmission at the ISM band
▪ Low transmission power, Low penetration properties
(walls, doors, windows etc)
▪ High transmission rate, High
▪ Low cost

7. Zigbee
▪ Wider range communication
▪ Transmission at the ISM band
▪ Low transmission power
▪ High transmission rate
▪ Support many nodes
