4:00pm

4.1) Co-exist with Clearwire

4:00pm
Manu Gosain (GPO) and Ivan Seskar (WINLAB)

  • Current approach, as an alternative to an agreement that leases Clearwire spectrum to GENI sites:
    • Operate under an experimental license from the FCC; otherwise require contract between site and Clearwire, with $ and conditions
    • Agreement between Rutgers WINLAB and Clearwire, on enhanced cooperation
    • Maintain accurate DB of site information and contacts at Rutgers, and share with Clearwire
    • Responsive local contact, at each site
    • Centralized monitoring server at Rutgers WINLAB
    • Ability to quickly turn off site transmitter, if interference suspected
    • Possible extension: remote emergency stop, with access to GMOC

How can we make it easy for experimenters?

f) Other topics:

Interworking with carriers (Clemson)
Use of carrier resources, i.e., WiNTeB
How could we add LTE? any match of equipment, frequencies and mobile stations?

g) CONCERN:

Do not have resources to do all of the above! how do we decide?

Paper including sections on basic and extended WiMAX sites, and on WiMAX research and service experiments: pdf

R3) Airspan Profile-C Base Station, with Associated Hardware and Software

Ivan Seskar (WINLAB) and Harry Mussman (GPO)

a) Choice of Airspan to provide a WiMAX base station for new GENI WiMAX sites
NEC is not able to provide a WiMAX base station for new GENI WiMAX sites
WINLAB and the GPO have decided to purchase base stations from Airspan, a commercial company pursuing target customers such as universities and small carriers.
For example, the Univ of Colorado at Boulder IT Dept has installed an Airspan system with 4 sectors, that covers the campus. They have been pleased with Airspan.
WINLAB has a frim quote from Airspan for their MacroMAXe profile-C WiMAX base station unit, and related items.

Airspan brochure
MacroMAXe Product Specification
Airspan Deployment Plan for Univ Colorado at Boulder

b) Rutgers will provide a kit including:
Airspan MacroMAXe profile-C WiMAX base station unit, for outside mounting

Choice of frequency:
(2510 Lo: 2496MHz to 2570MHz)
(2510 Mid: 2560MHz to 2630MHz)
(2510 Hi: 2620MHz to 2690MHz)
(3650: 3650MHz to 3700MHz)]

NOTE: WINLAB needs to know frequency choices during November (or early December), so that they can place an order with Airspan for delivery late 2011 or early 2012!

Sector antenna, with x4 RF jumper cables
2x4 MIMO, supported by base station and antenna
GPS antenna, with surge suppressor and cable
DC power cable, from base station unit (outside) to testbed (inside)
Network management software license, 1 per base station

c) Campus will need to provide:
Pole for mounting
DC power supply (-48v, approx 300W)
Ethernet cable, from base station unit (outside) to testbed (inside); consider copper (may be a problem with lightning surge) or fiber (requires MM fiber cable, and fiber interface on switch)
Windows server to host network management software
Linux server to host OMF software
Ethernet switches, and other network equipment, for access (configuration to be provided)

d) Additional kits can be purchased from Airspan

Price is approximately $15,000.

e) It is expected that additional base stations kits will be purchased for some (or all) Sol 3 GENI sites in Spiral 5.

Thus, campus site might be able to add additional sectors, at no cost.
Planning for next year will be done later this year.
Consider including additional sectors within your technical plan right away.

f) Note: Airspan indicates that they expect to introduce a new base station unit within the next year.

Somewhat reduced performance/range.
Approximately half the cost

g) Airspan indicates that their sector antenna provides:

A 90degree pattern, which is consistent with proper coverage over a 120degree sector.
Four internal elements, to support 2x4 MIMO.
Airspan can provide provide x4 omni-directional antennas, but the cost is much higher, and the range is signifcantly reduced.

h) Airspan shows that their profile-C base station unit can be configured to operate without an ASN GW and without a RADIUS (authentication) server.

In this mode, a list of allowed base stations must be configured into the base station, and groups of these base stations are mapped to a VLAN on the ethernet port.
This appears to be consistent with the current NEC base station unit operated with the ASN GW/WiMAX RF AggMgr code that has been provided by Rutgers/WINLAB
MacroMAXe Configuration Guide

i) Airspan shows that if handover operation is desired, an ASN GW must be provided, plus typically an associated RADIUS (authentication) server.

In this case, the base station unit operates with IP at the interface.

R4) Netspan Network Management System for Airspan Base Station

Manu Gosain (GPO)

  • Suggest: add Netspan system at each site with Airspan base station
  • Requires: Windows server
  • Use: setup of Netspan base station to provide basic functions

slides

installation instructions

  • Coming: replace with new WiMAX RF AggMgr

R5) Add OMF/OML to WiMAX sites

Fraida Fund (NYU Poly), Manu Gosain (GPO), Derek Meyer (Wisconsin),

  • Equip a WiMAX site with full OMF/OML capabilities, installing on VMs
  • Include Login Service for Remote Users
  • NYU Poly configuration:
  • 1) physical host acting as base station controller, runs the asn-gw and wimaxrf AM.
    • (1) and (2) run Ubuntu, (3) runs Windows.
    • It has Ethernet connections to the NEC IDU, NYU-Poly network (and Internet), and very soon GENI backbone (campus IS just informed me that they will be testing that tomorrow).
    • We have firewall rules set up so this host only accepts traffic from host (2) on the wimaxrf AM port. This allows us to make sure that only users with a current reservation can configure the BS.
  • 2) physical host running OMF 5.3 AM, EC, and some other services that are useful for the testbed.
    • (1) and (2) run Ubuntu, (3) runs Windows.
    • It has Ethernet connections to NYU-Poly network (internet) and OMF control network.
    • This is the host that testbed users log on to. We have firewall rules set up on this host so that only users with a current reservation can configure the BS or communicate with the testbed nodes.
  • 3) physical host that serves our group website and the reservation system for the testbed. It's connected to the NYU-Poly network (and Internet)
    • (1) and (2) run Ubuntu, (3) runs Windows.
  • Our testbed nodes are scattered throughout several CS labs and research areas (not part of our group).
    • They are connected to the pre-existing Ethernet jacks in the walls and floors of those rooms, which all go back to a CS server room, where we patch them through to our own (non-openflow) switch for the control network.
    • We do have an openflow switch that we plan to deploy somewhere at some point.
  • BBN experience (need summary)
  • All services are running on the same physical machine.
    • HP server that came with the base station.
    • The base OS is Debian and virtual machines using for the services (Virtualbox)
  • Physical machine network connections:
    • Eth0 (128.105.22.xxx): University network (internet)
    • Eth1 (10.3.8.126): Network to IDU of base station
    • Eth2 (10.0.0.1): Control network for omf
    • Eth3: Connected to openflow (physically, but not enabled until we can get a vlan tag to GENI backbone)
  • Base operating system: Debian
  • Virtualbox guests:
    • 1. Ubuntu 9.04 -> aggmgr 5.2 -> wimaxrf service
    • Eth0 (128.105.22.xxx): bridged interface to university network
    • Eth1(10.3.8.254): bridged interface to base station network
  • 2. Ubuntu 10.04 -> aggmgr 5.3 -> cmcStub, Frisbee, inventory, pxe, result, saveimage
  • Also expctl, resctl, and xmpp on same machine
  • Eth0 (128.105.22.xxx): bridged interface to university network
  • Eth1 (10.0.0.200): bridged interface to control network
  • Coming: plan to federate with ProtoGENI cluster
    • Reference: TridentCom 2012 : "Federating wired and wireless test facilities through Emulab and OMF: the iLab.t use case", Stefan Bouckaert (IBBT - Ghent University)
    • BBN is exploring how to utilize this to better integrate WiMAX sites into GENI, and be able to utilize the GENI AM API to assgin resources.

R6) Connect WiMAX sites to I2 backbone network, to support multi-site experiments

Manu Gosain (GPO), Fraida Fund (NYU Poly), Ivan Seskar (WINLAB)

  • Connect a WiMAX site to the GENI I2 backbone network
    • Update WiMAX RF Agg Mgr to map MS groups into VLAN tags
    • Add switch
    • Connect switch to I2 backbone
    • VLAN connections from each site to "L2 router" at WINLAB

slide

  • When can other WiMAX sites can be added?
    • UCLA; has physical connection; needs to configure; when?
    • Wisconsin; when?
    • Clemson; when?
    • UMass Amherst; has physical connection; needs to configure; when?
