Presentation Transcript

  1. The Poly WiMAX deployment • The BS (server, IDU) have been installed in the network room of the Library in the ECE Dept Building (5 Metrotech Center) • The outdoor parts (sector antenna, GPS antenna, ODU) have been installed on the roof of the ECE Dept Building (5 floor building) • We have got 2 experimental licenses from FCC to operate the WiMAX BS for 2 years

  2. Current Status • The testbed is up and running since September 2010 in a regular basis • WiMax connectivity on the nodes is tested using different devices such as Wimax Dongle, HTC EVO phones and Wimax laptops • The signal levels are tested (RSSI and SINR) to map the coverage area around the campus • Extensive throughput and delay measurements underway • Video conferencing is tested using the HTC EVO 4G phones.

  3. Base Station Installation • Sector antenna and GPS antenna installation

  4. Base Station Installation • ODU installation

  5. Server Installation • Server installation

  6. Clients • Beceem USB clients (Windows) HTC EVO phones • Dell Inspiron Mini 1012 (Linux) Intel Centrino Advanced-N 6250

  7. Base Station Installation • Poly’s location (Downtown Brooklyn)

  8. Measurements • Coverage range (20dBm)

  9. Measurements • Coverage range (3dBm)

  10. Measurements Dell Netbook 1012 Linux 10.0.4 Intel6250 Centrino Internal antenna NEC WiMAX BS Public Internet Base Station Test Host NYU-Poly GRE Tunnel • Indoors and outdoors measurements on throughput and delay (iperf) • Many variations in urban area • Throughput from 0.5 to 12Mbps • Asymmetry on the uplink and downlink 1 2 3

  11. Experiment 1 • Implementation of a WiMAX/WiFi cooperative recovery protocol • . WiMAX WiMAX broadcasting WiMAX WiMAX WiMAX Communication from the WiMAX interface Devices may experience data losses due to heterogeneous wireless channel conditions

  12. Experiment 1 Distortion Producer Video Client 1 Recovery Node wifi wimax TCP Transmitter wimax wifi WiMAX broadcatsing Video Client 2 CoopCluster wimax Communication from the WiFi interface Devices run a Cooperative Recovery protocol to dynamically form a cooperative recovery (ad hoc)network and recover the lost multicast data packets from other peers

  13. Experiment 2 ZigBee 30-40 feet • Development of a campus based power meter infrastructure based on the WiMAX deployment • Current solutions use Zigbee and USB connections, very low range ZigBee 30-40 feet USB Internet

  14. Experiment 2 • The data collected in the cloud can then be seen on a web browser or a smartphone.

  15. Experiment 2 ZigBee 30-40 feet • Use of the WiMAX deployment for transmitting the measuring data from the measuring points to the internet ZigBee 30-40 feet WiMAX Internet
