WiMAX Build-out Essentials
• Operation in Educational Broadband Services band
• WiMAX base station kit provided for each site
• Experiment control structure using OMF/OML – except UMass
Sponsored by the National Science Foundation
WiMAX Build-out Essentials
• WiMAX base station kit provided for each site– Open and programmable– Sliceable (can be shared, to support multiple
experiments)– Affordable (because limited to one 120-degree sector)– Software developed by Rutgers WINLAB and NEC
Labs; see http://groups.geni.net/geni/wiki/WiMAX
– Commercial WiMAX hardware (and low-level software) provided by NEC
– Kits built and distributed by Rutgers WINLAB; see http://groups.geni.net/geni/wiki/WIMXRG

WiMAX Build-out Status
• See current view at http://groups.geni.net/geni/wiki/WiMAXInteg
• All sites have FCC licenses– Most obtained experimental license within a few weeks after application
to the FCC• Sites in operation:
– Rutgers WINLAB (2Q09)– BBN Technologies (3Q10)– NYU Polytechnic (3Q10)– Stanford (separate process)
• Sites still being planned or installed:– UCLA– UC Boulder– Wisconsin (will add two kits to existing Cisco system)– UMass Amherst– Columbia Univ

BBN Infrastructure
• Outdoors:– Omni antenna (on top)
– NEC 120-degree sector antenna (aimed towards Boston)
– Patch antenna
– GPS antenna (for timing)
– NEC Outdoor Unit (ODU)
– Coax switching and power junction box
• Indoors:– NEC Indoor Unit (IDU)
– Base Station Server
– OMF/OML Server

BBN Mobile Stations (Clients)
• Windows PC with USB-connected WiMAX modem– Example: AWB (Accton Wireless Broadband) US210
WiMAX USB adapter, using Beceem chips, and works with any network ID
– Summary: debug monitor, useful to capture client RSSI, limited use on windows platform
• Linux PC with Intel 5150/6250 mini-PCI express card WiMAX modem. Samsung NC10 and Dell Inspiron Mini 10
• Android handset with WIMAX capability

WiMAX Mobile Station: Linux PC
• Linux PC with Intel 5150/6250 mini-PCI express card WiMAX modem– Examples: Samsung NC10,
Dell Inspiron Mini 10– Open-source driver, can work
with any network ID– Full support for custom
applications– Full support for OMF/OML
applications and control, including image loading
– Summary: Currently the most capable client
Intel 5150/6250mini-PCI express cardwith Linux driver
OMF/OML Client Srvc’s
Experiment App Resource Cntrl Measurement Client

WiMAX Mobile Station: Android Handset
• Android handset with WIMAX capability– Example: HTC EVO 4G
handset, sold by Sprint– As sold, locked to Sprint; how
to allow connection to GENI network?
– How to support custom applications?
– How to support OMF/OML applications and control?
– Summary: Very attractive for certain uses; working to resolve issues

BBN Experiments: Internet Access
• Internet access– Default slice– Mobile associates, after matching with entry in access
list– Mobile gets added to default slice, starts UL traffic– Allows browsing, etc., from mobile, and verifies basic
functionality– Status: Working
