  1. Wireless / WiMax Applications

  2. Wireless / WiMax Applications System Overview Wireless Local Loop (WLL) Power Protection Opportunities AC Power Overvoltage Protection DC Power Overvoltage Protection Communication Interface Opportunities SLIC interface T1/E1 Interface T3 Interface HDSL Interface VDSL Interface Ethernet Interface Antenna Protection Outline

  3. WiMax Base station units CPE units

  4. WiMax – CPE hardware CPE hardware for WiMax service includes the Indoor Subscriber Unit = protection location

  5. WiMax Base Station Wireless Local Loop (WLL) The WLL is a Remote Terminal connected to the PSTN wirelessly: WLL Wireless Interface Multiplexer Internet Data Voice Video Subscriber Line Interface Card (SLIC) DSL Access Module (DSLAM) T1/T3 Driver MDF / Protected Cross-Connect Subscriber Lines

  7. AC Power Overvoltage Protection MOV – L – TVS Pi Network • Select MOV for long life. • Use only air core inductors. • Select TVS for low clamping voltage and minimum cost.

  8. DC Power Overvoltage Protection Photos roughly to scale It would take about 10 75V KPA devices to achieve this protection performance. See the AK TVS Module for more information.

  10. SLIC Interface Negative Ringing SLIC: B1101UC Pos/Neg Ringing SLIC: B3104UC See the SLIC Protection Module for more information.

  11. T1 / E1 Interface Protection • P0080SAMC or P0080Q12A Tertiary Protection • P2106UC or SDP1800Q38CB Line Protection

  12. T3 Interface Protection 04611.25EER 1,8 • Broadband Optimized SIDACtor: P0642SA • For High Surge Requirements: SDP0640Q38CB SDP0640Q38CB 4,5

  13. HDSL Interface Protection • Line Protection: P2300SCMC or P2300Q22C • Tertiary Protection: P0080SAMC or P0080Q12A

  14. VDSL Interface Protection • Tertiary Protection: SDP0240Q12F and SP3050 • Line Protection: SDP3500Q38CB See the Tertiary Protection and Broadband Protection Modules for more information.

  15. Ethernet Interface Protection • Line Protection: SEP0080Q38CB • Tertiary Protection: SP3050 See the Ethernet Protection Module for more information.

  16. Antenna Protection RF Line To Transceiver • P1900ME SIDACtor rated for 5000A 8x20 Surge • Inductor isolates RF signal from SIDACtor • During a surge the inductor “disappears” • Special Inductor Design • Very small high permeability core • Few turns of heavy copper wire • Tuned to unused band
