Mobile Web’s Potential
• Mobile Tech 2011• The Future is Now
3
Mobile Devices
• Laptop/Netbook/Ultrabook computers• Personal Digital Assistants – Tablets– Gaming Devices– E-Readers
• Smart Phones• Padfone
4
Mobile Communications
• Bluetooth• Radio Frequency Identification (RFID)• Near Field Communications (NFC)• WiFi (Wireless Fidelity)• WiMax• 3G• 4G
5
Bluetooth
• Packet-based protocol• Master & 7 slaves in a piconet• Low power• < 30 m range• 1-3 Mbits– 1 Mbit = 64k characters
6
RFID
• Uses radio-frequency electromagnetic fields to transfer data from a tag to an object
• Passive tags require no batteries• Can be read from several meters away
