4.1 WiMAX Standards

Ongoing WiMAX standards work is done by the WiMAX Forum. See, for example, the WiMAX Forum Technical Specifications

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:

Fig 6-1) Network Reference Model

Fig 6-2) ASN Reference Model

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.

4.5 System Engineering Issues

No Issue Who Opened Resolved Resolution Note
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". Michel 2/23/10 - - Per Seskar, apply at IEEE 802.16 site. Fee is $1200.
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. Also, how this varies depending on the number of clients and their data rates. Then, need to verify at sites, Michel, Seskar, Rangarajan 2/23/10 - - On 3/16: Expect standard range information from NEC in 2+ weeks. Ott on 3/16: Should consider planning tools seen at 3G trade shows, to estimate ranges. Michel on 3/10: Preparing emasurement plan.
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. Michel, Seskar 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
4.4 "GENI PKI Certificate": If we want to do over-the-air provisioning to clients, we will require a PKI certifiacte signed by Verisign, that clients can verify (per Seskar). Michel 2/23/10 - - Need to decide how GENI would use this; if worthwhile, then plan process to obtain one.

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.

It includes a map of the participating campuses:

And a list of involved researchers and IT leaders:

5.2 GENI WiMAX Usage Plans

The WiMAX Kit Project (1753) outlined the usage plans for each campus:

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:

NEC Labs America
Stanford

The WiMAX Kit Project (1753) is purchasing and supplying WiMAX campus deployment kits to the following campuses. In addition, it is providing a limited number of client platform kits.

Rutgers, Bush Campus
Columbia University
Polytechnic Institute of NYU
UCLA
University of Colorado at Boulder
UMass Amherst
University of Wisconsin

The following GENI-related campuses/sites are purchasing the necessary equipment to build their own WiMAX campus deployment kits, and then deploying them with aid from the GPO and Rutgers WINLAB:

BBN Technologies, Cambridge, MA
University of Wisconsin, 2nd site

The following campuses/sites have indicated an interest in obtaining their own WiMAX campus deployment kits:

University of North Texas (Prof Kamesh Namuduri on 3/16)
Florida International University

Ray Raycaudhuir on 3/16: 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

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 4 cases for 3 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/Cleariwre, 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.

6. WiMAX Campus Deployment Kit

Fig 1-1) System Overview

6.1 Configuration

Fig 1-2a) System Configuration with Three Servers

Figure 1-2a) shows the system configuration with three servers:

ASNGW-03, that provides combined ASN GW functions.
ASNGW-02, that provides virtualized ASN GW functions, for separate slices.
OMF-04, that provides a set of OMF/OML functions.

In some cases, a campus already has a set of OMF/OML functions, and would likely not require the OMF-04 server:

Rutgers, WINLAB
Rutgers, Bush Campus
Polytechnic Institute of NYU

In many cases, it should be possible to combine the ASNGW functions into one server, for a total of two servers; see Figure 1-2b.

Fig 1-2b) System Configuration with Two Servers

6.2 Base Station Hardware

Fig 1-2b) NEC BTS IDU and ODU Base Station Hardware

6.3 WiMAX Antenna

There are two 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
  • Commercial 360-degree omni-directional antenna, not provided by Rutgers as part of the kit

See:

Each campus should decide on the appropriate antenna; see Section xx below.

The antenna must be connected to the NEC ODU using a short length of low-loss cable, with N-type connectors:

  • LMR-400 up to 6 ft.
  • LMR-600 greater than 6 ft.

Note that the loss in the cable can have a significant impact on range.

See:

It may be possible to include two antennas, with a manual or electronically-controlled coaxial switch. UNDER STUDY

6.4 GPS Antenna

Ivan: Inclusion and choice of GPS antenna, for timing to base station
Candidate is PCTel GPS-TMG-SP-40NGPS timing reference antenna, with integrated lightning protection
ISSUE: Pick antenna with appropriate gain, and coax cable with appropriate attenuation.

The same antenna/mounting combo comes with 10, 20 and 40 dB of gain (the only issue is possible ringing with high gains so for cases where there is less than 50m of cable we should go with 10 or 20 dB max). I would definitely go for heavy duty mounting (like this one because it has built-in arrester so that all we need is a proper grounding which presumably already exist for the main antenna). As for what cable and where to get them, there are quite a few outfits; for example the site for WiMAX antenna:

From: Harry Mussman hmussman@bbn.com Sent: Wednesday, March 31, 2010 11:37 AM To: 'michel,tony'; Ivan Seskar Cc: 'Harry Mussman' Subject: gps antenna and cable

Tony and Ivan,

I am updating the wiki, and am looking for:

1) gps antenna spec.

Per Ivan earlier, a good one is attached.

Which mounting hardware? Heavy duty?

2) gps antenna coax cable

Assume: up to 100m, like fiber?

Overall loss budget:

Output from antenna?

Input range to NEC ODU?

What coax, loss?

Connectors:

NEC IDU: GPS Antenna Terminal (GPS ANT): BNC connector

GPS antenna: N, female (one - bottom fed)

Can we find a place that supplies cable with connectors?

6.5 -48VDC Power

Both the NEC ODU and IDU are, as telecom systems, powered by a -48VDC power source.

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. Furthermore, it allows the power supply for the ODU to be mounted in a weathertight box on the roof, if that is preferred to mounting with the indoor testbed equipment.
Power feed connections are outlined in the NEC Installation Manual for Base Station (IMN:BS)

The recommended configuration for 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.
One power supply for ODU, Mean Well SP-200-48, 110VAC input, -48VDC output, rated 4.2A or 200W, mounted in testbed equipment room, or outdoors on roof, in weathertight enclosure (see UMass Amherst).

The recommended configuration for 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

Fig 1-2a) Hardware and Networking

Figure 1-2a) shows the full configuration with three servers:

ASNGW-03, that provides combined ASN GW functions.
ASNGW-02, that provides virtualized ASN GW functions, for separate slices.
OMF-04, that provides a set of OMF/OML functions.

In some cases, a campus already has a set of OMF/OML functions, and would likely not require the OMF-04 server:

Rutgers, WINLAB
Rutgers, Bush Campus
Polytechnic Institute of NYU

For the initial bringup, it should be possible to load all functions into one server.

Issue: Are there campuses that can complete their expected experiments operating with only one server? two servers?

6.7 Software Modules

6.8 Messages and APIs

6.9 Virtualization

6.10 Control and Management

Fig 1-5) Control and Management

6.11 Backbone Network Access

6.12 Federation

During initial bringup, each WiMAX testbed will operate as a self-contained OMF-controlled testbed.

Then, various WiMAX testbeds will be federated, by implementing:

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.

Issue: How will federation among WiMAX testbeds be accomplished?

Issue: How will WiAMX tesbeds be connected together, using a VLAN carried by a GENI backbone?

6.13 Monitoring and Management

6.15 Kit Software

6.16 Kit Integration and Delivery

The WiMAX Kit Project (1753) divided up projects tasks this way:

The WiMAX Kit Project (1753) established this high-level schedule:

Software releases follow this plan:

Release Features Released Delivered Where Note
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:

Kit Ordered Received Integrated Delivered Where Note
1.1 2008 2009 2009 2009 Rutgers, WINLAB p/o ORBIT testbed
1.2 2008 2009 2009 2/2010 Rutgers, Bush Campus applications

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: NEC Labs America, Columbia University, and Polytechnic Institute of NYU. 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 may also depend on campus status.

2.1 12/17/09 plan 5/15/10 ? Spiral 2 (7/1/10) NEC Labs America ?
2.2 12/17/09 plan 5/15/10 ? Spiral 3 Columbia University ?

On 2/23, we agreed to include in the kit, since total cost is likely to be less than $125, and it should be installed at the start. Michel, Seskar 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
