4.1 WiMAX Standards
4.2 WiMAX Network Architecture
An technical overview of WiMAX network architecture is presented in WiMAX Forum Network Architecture Release 1.0 Version 4 - Stage 2: Architecture Tenets, Reference Model and Reference Points, including:
4.3 GENI WiMAX Project Technical Overview
A technical overview of the GENI WiMAX project is presented in: GENI WiMAX Project: System Engineering Summary.
The GENI WiMAX project currently utilizes commercial NEC WiMAX equipment as the basis of its WiMAX campus deployment kit, including a Profile A Base Station and a separate ASN Gateway, joined by the R6 interface, per Figure 6-2, above. The R6 interface implementation is not fully standardized, and thus includes NEC-specific functions.
For the GENI WiMAX project, the WiMAX campus deployment kit provides the GENI Researcher with much flexibility:
The use of a Profile A Base Station with an exposed R6 interface enables the researcher to monitor and control the base station radio functions.
The ASN gateway utilizes some essential NEC code, but removes many high-level WiMAX functions (e.g., roaming) and allows the researcher to implement their own.
Finally, the ASN gateway includes slicing functions, to allow the base station and ASN gateway to be shared by multiple researchers at the same time.
Later in 2010, NEC will be updating their WiMAX equipment to utilize a Profile C Base Station, where some of the current ASN gateway functions are included in the Base station, and fully standardized R6 interface is exposed. When this occurs:
The current GENI-specific ASN gateway software will have to be modified, with an effort of at leat 2 MM.
The researcher will have diminished ability to monitor and control the base station radio functions.
4.4 GENI WiMAX Base Station Range and Capacity
Need to be able to estimate the expected range and capacity of a completed installation, and how this varies with antenna height, to guide each campus in their planning. Also, how this varies depending on the number of clients and their data rates.
Then, need to verify estiamtes with measurements at various sites.
Ivan Seskar: Have some data from Rutgers WINLAB site, and expect more when Rutgers Bush Campus site is in service. Can configure split between downstream and upstream. With 10MHz bandwidth, limited to approximately 20Mbps total. Have seen range approximately x10 of WiFi? range. Have seen downstream of 2+Mbs at 2km combined with 7Mbs at short distances.
Ray Raychaudhuri on 3/16: Expect standard range information from NEC in 2+ weeks.
Max Ott on 3/16: Should consider planning tools seen at 3G trade shows, to estimate ranges.
Tony Michel on 3/30: Preparing plan to measure base station range and capacity at BBN Technologies site, starting with initial checkout.
Harry Mussman on 4/30: WiMAX Forum document on WiMAX Forum: "Mobile WiMAX – Part I: A Technical Overview and Performance Evaluation", March 2006 provides good information on range and capacity, including Dl and UL link budgets for a nominal case.
4.5 System Engineering Issues
|4.1||"GENI Operator ID": Each WiMAX deployment requires an Operator ID (OpID), a parameter used within the base station and each client. Currently, Routgers WINLAB is using the Sprint/Clearwire ID, but this can only be temporary. We need to apply for and receive a "GENI Operator ID".||Agosain||2/23/10||4/30/10||From IEEE: company_id is: 4451DB16, represented as a conventional 6-digit hexadecimal integer. Tutorials to help implement the use of the I.D. assignment Basis for the IEEE 802-2001 tutorial||Per Seskar, apply at IEEE 802.16 site. Fee is $1650.|
|4.2||Range and capacity: Need to be able to estimate the expected range and capacity of a completed installation, and how this varies with antenna height, to guide each campus in their planning.

|4.3||GPS receiver: NEC documentation shows a GPS receiver mounted along with the antenna, and connected to the NW INTFC on the IDU. It provides precise timing signals to the base station.||Seskar, Mussman||2/23/10||2/23/10||Agreed to include in the kit, since total cost is likely to be less than $125, and it should be installed at the start.||Next: Need to engineer active antenna and cable for up to 100m; see Kit Issues|

5. GENI D&P WiMAX Infrastructure Buildout
5.1 GENI WiMAX Buildout Plan
The overall GENI buildout plan is funded by an NSF contract, and is summarized in GENI D&P WiMAX Infrastructure Buildout.
5.2 GENI WiMAX Usage Plans
Each project has been reviewing and updating their plans for research, which will help drive design of kit and software. See Section 11, "WiMAX Experiments and Demos".
5.3 GENI WiMAX Kits
As part of the Spiral 1 WiMAX D&P prject, two WiMAX campus deployment kits were purchased for:
Development at Rutgers, WINLAB
Service at Rutgers, WINLAB
The following campuses/sites purchased their own kit:

New kits would be Profile C
Expect NEC would like to see orders for 40-50, if possible
5.4 GENI WiMAX Licenses
Each GENI WiMAX campus/site must have a valid FCC license to operate a WiMAX base station. In some cases, a campus/site plans to use an existing "educational license" already held by their institution. However, in most cases, the campus/site plans to apply for and use a new "experimental license" that, by and large, can be obtained just by requesting it from the FCC. This process has been successful in 6 cases for 5 campuses/sites. See Section 8.2, "Obtain FCC License".
However, in almost all situations, there is a potential overlap with the ongoing national Clearwire/Sprint WiMAX rollout. (See the list of current and planned deployments below.) This is true for several reasons.
If a GENI WiMAX campus/site plans to use an existing "educational license" already held by their institution, which has not yet been leased to Clearwire/Sprint, there is a reasonable chance that the institution may yet pursue a lease with Sprint/Clearwire, and thus the GENI WiMAX campus/site could lose their license.
In the cases where the institution has leased their "educational license" to Clearwire/Sprint (which may or may not have started service), all is not lost. A new upcoming rule apparently requires that an institution that has leased their "educational license" must retain "at least 5%" for their own use, or else forfeit their license. So, a GENI WiMAX campus/site may gain partial access to an "educational license" even if it has alreasy been leased to Clearwire/Sprint.
In the cases where a GENI WiMAX campus/site plans to apply for and use a new "experimental license", it has been found that most available spectrum has been leased to Sprint/Clearwire, although they are not yet using it in most locations (see below). So, the FCC will grant an "experimental license" that overlaps spectrum already leased (likely to Clearwire/Sprint), but they require: if the owner of the spectrum (i.e., Clearwire/Sprint) begins service, the holder of the "experimental license" must stop using the spectrum immediately.
So, what does this all mean?
1) If a GENI WiMAX campus/site uses an "educational license" already held by their institution (or "5% of one", by the upcoming rule), they are OK (unless the institution decides to lease the license).
2) If a GENI WiMAX campus/site uses an "experimental license" that does NOT overlap a license holder, they are OK.
3) If a GENI WiMAX campus/site uses an "experimental license" that DOES overlap a license holder, they are OK UNTIL that license holder (i.e., Clearwire/Sprint) decides to start using that spectrum, and then they will have to shut down their WiMAX base station. This is a significant concern in major metropolitan areas, per the deployment plans listed below.
However, this could change. An NSF effort is beginning to define a Wireless National-scale Test Bed (WiNTeB); this could possibly affect the allocation of spectrum to national testbed uses.
Another possible strategy has been identified by Tony Michel. In at least three locations, (Boston, Sussex Cty, MA; Brooklyn, Kings Ct, NY; Manhattan, NY Cty, NY) he has identified a 5-MHz slice of specturm in the educational band with no assigned licenses.
BBN technologies has applied for and been granted an experimental license for the 5-MHz slice in Sussex County.
PIs at NYU Poly and Columbia are in the process of appplying for experimental licenses for the 5-MHz slices in their counties.
Assuming that both NYU Poly and Columbia are grnated experimental licenses in their respective 5-MHz slices (smae frequencies, but geographically separated), then the NYU Poly and Columbia institutions should be able to apply for and be granted full educational licenses in the slices. What does this mean?
4) If so, NYU Poly and Columbia would be able to use full educational licenses without challenge from Sprint/Clearwire or any other commercial enterprises.

5.5 GENI WiMAX Buildout Issues
|5.1||Who wants additional kits: We need to compile a list of GENI-related campuses and sites that want to purchase the necessary equipment to build their own WiMAX campus deployment kits.||Mussman||12/09||3/16/10||BBN and 2nd for Wisconsin going ahead; U Norht Texas and FIU waiting.|

6. WiMAX Campus Deployment Kit
A full WiMAX testbed system configuration utilizes three servers, per Figure 1-2a):
ASNGW-C, that provides combined ASN GW functions, and includes a CLICK router.
ASNGW-V, that provides virtualized ASN GW functions, for separate slices, with one VM assigned to each slice.
OMF, that provides a full set of OMF/OML functions.
All servers run ubuntu Linux, and the ASNGW-V server implements kvm virtualization.
In some cases, it should be possible to combine the ASN GW functions into one server, for a WiMAX testbed system configuration that utilizes two servers, per Figure 1-2b).
ASNGW, that provides all ASN GW functions OMF, that provides a full set of OMF/OML functions.
Both servers run ubuntu Linux, and the ASNGW server implements kvm virtualization, with the combined ASN GW functions (non-virtualized) running in Dom0.
In some cases, a campus already has a set of OMF/OML functions, and would likely not require the OMF server:
Rutgers, Bush Campus
Polytechnic Institute of NYU
Finally, in many cases, it should be possible to combine all funtions within one server, for a WiMAX testbed system configuration that utilizes one server, per Figure 1-2c).
ASNGW-OMF that provides all ASN GW and OMF/OML functions.
This server runs ubuntu Linux, and implements kvm virtualization, with the combined ASN GW (non-virtualized) and OMF/OML functions running in Dom0. Note that this server must have a total of four ethernet ports to provide all of the required conenctivity.
When this configuration uses a high-capacity (i.e., dual-CPU) server, it should have sufficient capacity for most installations. Thus, it is the configuration that will be used for the initial installations at all campuses/sites.
Later, additonal servers can be added as necessary for capacity. For example, if specialized functions such as video coding were included in a slice's VM, then additional capacity may be required.
6.2 Base Station Hardware
The NEC BTS base station hardware includes the following units, ashown in Figure 1-2d:
- OutDoor? Unit (ODU), bolted to a pole near the WiMAX antenna, and connected via a coax to the WiMAX antenna.
- InDoor? Unit (IDU), rack mounted in an equipment room, connected via a dual fiber cable to the ODU.
For installation details, see NEC Installation Manual for Base Station (IMN:BS)
6.3 WiMAX Antenna
There are three types of 2.6GHz WiMAX antennas that may be installed at the site:
- NEC 120-degree sector antenna, provided by Rutgers as part of the kit. See NEC Sector Antenna Installation Manual
- Commercial 2.6GHz 360-degree omni-directional pole antenna, not provided by Rutgers as part of the kit
- Commercial 2.6GHz 30-degree directional patch antenna, not provided by Rutgers as part of the kit
Each campus should decide on the appropriate antenna (or antennas), for thier planned experiments and their local topography.
The antenna must be connected to the NEC ODU using a short length of low-loss cable, with N-type connectors:
- LMR-400-series cables with N-type connectors, with 0.68 dB loss for 10 feet
- LMR-600-series cables with N-type connectors, with 0.44 dB loss for 10 feet; recommended for long runs
Typical WiMAX cable components are:
- N-male to N-male cable, 2 feet in length.
- N-male to N-male cable, 4 feet in length.
- N-male to N-male cable, 10 feet in length.
- N-female to N-female connector, to join two cables with N-male connectors.
Note that the loss in the cable can have a significant impact on range.
It should be possible to include two (or more) antennas, and move the coax cable between antennas to select the antenna in use.
As an alternative, a coaxial relay switch can be mounted in a wether-tight box on the roof (see below), and used to remotely select the antenna in use.
6.4 GPS Antenna
A GPS antenna is mounted on the roof and connected to the IDU to provide a stable and precise timing source to the base station.
The GPS antenna can be mounted in any outdoor location where it can "see" the sky, but it is typically mounted in the same location as the WiMAX antenna.
The suggested GPS antenna is the PCTel GPS-TMG-SPS-40NCB timing reference antenna. It provides:
- integrated lightning protection
- heavy duty mounting clamp
- amplifier with 40 dB of gain
The GPS antenna is connected to the NEC IDU using a 50-ohm coax, that carries the received signal to the IDU, and power to the antenna assembly. Connectors are:
- NEC IDU: GPS Antenna Terminal (GPS ANT): BNC connector
- GPS antenna: N, female (one - bottom fed)
The suggested 50-ohm coax cable is RG58C/U, which has a loss at the GPS frequency of approxiamately 1000MHz of 40 dB for 200 ft of cable. The amplifier with 40 dB of gain compensates for this loss.
Typical GPS antenna cable components are:
- BNC-male to BNC-male cable, multiple lengths.
- BNC-male to BNC-male cable, 200 ft length.
- BNC-female to BNC-female connector, to join two cables with N-male connectors.
- BNC-female to N-male connector, to join a BNC-male cable to the GPS antenna assembly
6.5 -48VDC Power
Both the NEC ODU and IDU are, as telecom systems, powered by a -48VDC power source. Power feed connections are outlined in the NEC Installation Manual for Base Station (IMN:BS)
It is recommended that two separate -48VDC power supplies, with 110VAC feeds, be provided, one for each unit. This avoids the need for a -48VDC distribution panel, with circuit breakers, and yet still allows individual control for each unit.
The power supply for the ODU is typically mounted indoors, with the indoor testbed equipment. Optionally, it can be mounted in a weather tight box on the roof (assuming a 110VAC supply is avaialble on the roof).
The typical configuration for powering the ODU is:
- ODU mounted outdoors, on roof, with maximum of 4A required at -48VDC
- One 10m (approx 30ft) outdoor power cable, two conductors, 12AWG, rated for outdoor use, with ODU Circular Connector, soldered onto cable.
- Lightning surge protector mounted on a barrier terminal block in a weather tight box on the roof.
- Additional outdoor power cable, two conductors, 12AWG, rated for outdoor use, for connection between the roof and the power supply mounted in the equipment room.
- One power supply for ODU, Mean Well SP-200-48, 110VAC input, -48VDC output, rated 4.2A or 200W, mounted in the testbed equipment room.
Typical outdoor cable:
The typical configuration for powering the IDU is:
- IDU mounted indoors, in testbed equipment room, with maximum of 8.4A required at -48VDC (in full configuration with all 3 sector boards).
- One 10m (approx 30ft) indoor power cable, two conductors, 10AWG, with one IDU Rectangular Power Connector and four IDU Rectangular Power Connector Contacts , two for each of the positive and negative DC power rails, crimped onto cable with a special tool, or soldered.
- One power supply for IDU, Mean Well SP-320-48, 110VAC input, -48VDC output, rated 6.7A or 320W, mounted in tesbed equipment room.
6.6 Server Hardware
Per Section 6.1, the system can be configured with as many as three servers, but will be configured with one server for initial bringup, per Figure 2-1c).
The recommended server hardware for the one-server configuration is:
6.7 Software Modules
6.8 Messages and APIs
Ivan on 3/16: One server uses kvm virtualization, with one VM per slice.
Use VLAN tags to identify flows between servers.
Expect to use Best Effort (BE) queue in WiMAX base station, so that can individually control flows in ASN GW.
Giovanni: Prefers zen for virtualization, since lightweight.
Max: Likes kvm virtualization, since easy to setup.
6.10 Control and Management
Control and management of each WiMAX testbed will be done via OMF; see Figure 1-5):
6.11 Backbone Network Access
Each WiMAX testbed must be connected to a L2 and/or L3 backbone network to handle experiment data flows; see Figure 2-1a). The VLANs associated with each slice must be switched to the appropriate backbone VLAN, or to the backbone L3 network.
The Rutgers WINLAB testbed has been connected to the Internet2 backbone network, and has used the ION service to extend L2 (VLAN) connections to the NICTA and BBN testbeds. Thus, Internet2 is the preferred backbone for all WimAX testbeds.
During initial bringup, each WiMAX testbed will operate as a self-contained OMF-controlled testbed.
Then, various WiMAX testbeds will be federated, by:
Connecting the Management and Control Networks of the testbeds together using a multipoint VLAN provided by the GENI backbone, to permit coordinated OMF control of two or more testbeds by one experimenter.
Connecting experiment data from testbeds together, using a VLAN carried by a GENI backbone.
See Section 9.
6.13 Monitoring and Management
Monitoring and management of the WiMAX testbed will be done via OMF.
See Section 10.

6.15 Kit Software
All kit software will be provided by Rutgers WINLAB and maintained on the OMF web site. (Note: it is currently located on the ORBIT website.)
6.16 Kit Integration and Delivery
Software releases follow this plan:
|v1.0||-||Plan 10/1/09 (Spiral 1)||-||Rutgers WINLAB||For first demos and experiments|
|v2.0 (GBSN v3.0)||-||Plan 7/15/10 (Spiral 2)||-||-||For use with first delivered kits|
|v2.1 (GBSN v3.1)||-||Plan 11/2010 (Spiral 3)||-||-||-|
|v2.2 (GBSN v3.2)||-||(Spiral 4)||-||-||-|
The first sets of kit hardware were ordered in 2008 and delivered in 2009, as part of Spiral 1:
|1.1||2008||2009||2009||2009||Rutgers, WINLAB||For development|
|1.2||2008||2009||2009||2/2010||Rutgers, WINLAB||p/o ORBIT testbed|
The second sets of kit hardware were ordered in 2009 and will be delivered in 2010 and 2011, as part of Spirals 2 and 3.
Issue: It has been planned that three kits will be delivered during Spiral 2 (7/1/10), and the remaining four during Spiral 3. It has been planned that the first three kits will be delivered to campuses/sites where there is easy access for support, i.e., at nearby locations: Rutgers Busch Campus, Columbia University, Polytechnic Institute of NYU, and/or UMass Amherst. However, it would also make sense to deliver a kit ONLY when the campus/site has received an FCC license, and is ready to install the kit. Thus, the delivery sequence will depend on campus status.
|2.1||12/17/09||4/20/10||?||Spiral 2 (planned 7/1/10)||Rutgers, Busch Campus||Applications|
|2.2||12/17/09||4/20/10||?||Spiral 2/3 (planned 9/1/10)||Columbia University||?|
|2.3||12/17/09||4/20/10||?||Spiral 2 (planned 7/1/10)||Polytechnic Institute of NYU||?|
|2.5||12/17/09||4/20/10||?||Spiral 3||University of Colorado at Boulder||?|
|2.6||12/17/09||4/20/10||?||Spiral 2 (planned 7/1/10)||UMass Amherst||?|
|2.7||12/17/09||4/20/10||?||Spiral 3||University of Wisconsin||?|
A third set of kit hardware was ordered in 3/2010 and will be delivered in Spiral 1, for those campuses not included in the Spiral 2 projects, or for campuses that want to install additional kits.
|3.1||3/10||?||?||(early planned 6/1/10)||BBN Technologies||Could a kit from the second set be delivered for use until this kit is received?|
|3.2||3/10||?||?||?||University of Wisconsin, 2nd site||?|
6.17 Kit Issues
|6.1||No. of servers in kit: Are there campuses that can complete their expected experiments operating with only one server? two servers?||Mussman, Seskar, team||-||4/2/10||Agreed to start with one high-capacity server, supplied by Rutgers; later, can add additional servers if more capacity neeed.||-|
|6.2||Federation of WiMAX testbeds: How will federation among WiMAX testbeds be accomplished?||Mussman, Seskar, team||-||-||-||-|
|6.3||Connection of WiMAX testbeds: How will WiMAX testbeds be connected together, using a VLAN carried by a GENI backbone?||Mussman, Seskar, team||-||-||-||-|
|6.4||Kit delivery sequence: It has been planned that three kits will be delivered during Spiral 2, and the remaining four during Spiral 3. It has been planned that the first three kits will be delivered to campuses/sites where there is easy access for support, i.e., at nearby locations: Rutgers Busch Campus, Columbia University, Polytechnic Institute of NYU and/or UMass Amherst. However, it would also make sense to deliver a kit ONLY when the campus/site has received an FCC license, and is ready to install the kit. Thus, the delivery sequence will depend on campus status.||Mussman, Seskar, team||-||5/1/10||5/1: Current delivery sequence is: BBN; NYU Poly; Columbia and possibly UMass Amherst.||-|
|6.5||Kit contents: Agreed to move power supplies into category provided by Rutgers, since cost is low ($115); also, use only larger supply.||Seskar, Michel, Mussman||2/23/10||2/23/10||-||-|
|6.6||Kit contents: Agreed to move GPS receiver into category provided by Rutgers, since total cost is likely to be less than $125, and it should be installed at the start.||Seskar, Michel, Mussman||2/23/10||2/23/10||-||Need to engineer active antenna and cable for up to 100m, and need a BOM for active antenna, arrestor and cable. Candidate is PCTel GPS-TMG-SP-40N|
|6.6||GPS receiver: Need to engineer active antenna and cable for up to 100m, and need a BOM for active antenna, arrestor and cable.||Mussman||2/23/10||4/10/10||-||Chose PCTel GPS-TMG-SP-40N GPS antenna assembly with 40-dB of gain, and 200-ft of RG58C/U cable, with 40dB of loss at 1000MHz|
|6.7||Kamesh Namuduri: Univ North Texas interested in kit to do research||Ray||3/16/10||3/16/10||Would prefer to get existing deployment underway, and then consider a 2nd round of kits beginning in 5+ mo.||New kits would be Profile C. Expect NEC would like to see orders for 40-50, if possible|
