3. • Typical Enterprise Mobile device must support many radios: WAN (5G), WiFi, BT, RFID, NFC, etc
– Limited space for RF antennas
– Antenna coexistence challenges
– Ergonomically located NFC antennas for best customer experience
– Must support good NFC reding/writing performance and NFC Form Certification
• Power requirements - battery capable of sustaining minimum for 10-12 h shifts.
– Battery swap capabilities required in some cases
– Battery capacity >4000Ah
• NFC Use cases: Access control, Bluetooth Paring, Payment, Proof of presence, Transportation Ticketing, Device, Product
authentication, etc
• Quick / Rapid charging required in many use cases
• Charging Power 10-15W minimum

Wireless charging technologies, NFC versus Qi
• Efficiency >50%
• Efficiency Very insensitive to antenna misalignment
• Ideal for batteries <500mAh
• No bulky coil needed
• Efficiency ~ 75 -80%
• Efficiency Sensitive to antenna misalignment
• Bulky coil needed

5. ZEBRA TECHNOLOGIES
What is NFC charging and how differ from Qi Charging
• NFC charging is an extension of the data protocol that
now allows devices using NFC to transfer data and
power
• Initially NFC was supporting power harvesting less
than 100 mW
• NFC Charging frequency of operation is 13.56MHz
• Data rate up to 106kb/s
• Loose and tight coupling
• Smaller coil sizes
• Less reliant on coupling (freedom of placement)
• Wireless Power Standards
• Qi Charging frequency of operation 100-200kHZ
• Power levels up to 15W for mobile devices
• Power levels for Ki (Kitchen appliances) up to 2000W
• Officiant power transfer
• Data rates 2kb/s
• Tight coupling

Enterprise NFC Charging Advantages and Disadvantages
Zebra
Advantages and disadvantages of NFC Charging for Enterprise Devices
Advantages
• Single Antenna to support NFC charging/data
allowing product to save board space and cost
(lowest BoM with minimum footprint)
• Smaller coil size
• Simplified design and testing (lower cost)
• Faster product time to market
• Convenient easy to use
• Sealed devices, Water and dust proof
• Less reliant on coupling (freedom of placement)
Disadvantages
• More expensive Dedicated NFC chip with support
of NFC Wireless charging
• Tuning complexity between efficient best charging
capabilities and data transfer .
• Supporting power up to 3W max only
• Data rate up to 106kb/s with higher power settings
• Limited NFC use cases support

7. • It is an attractive solution for small IoT devices with low power requirements (batteries < 500mAh).
• Not suited as a main charging power source for Enterprise devices with higher power requirements (min
requirements 10-15W).
• Complimentary power charging source possible.
• Qi technology is more suited for Enterprise.
• Can limit the NFC performance while tunned for higher power efficiency
