4. System Engineering

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

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. Michel, Seskar 2/23/10 - - 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. NEC will not release their range info. Need to check open WiMAX literature, and measure.
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. 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
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:

ISSUE: Each project should review and update their plans for research, which can help drive design of kit and software.

5.3 GENI WiMAX Kits

As part of the Spiral 1 WiMAX D&P prject, two WiMAX campus deployment kits were purchased for:

Rutgers, WINLAB
Rutgers, Bush Campus

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.

NEC Labs America
Columbia University
Polytechnic Institute of NYU
UCLA
University of Colorado at Boulder
UMass Amherst
University of Wisconsin

The following campus purchased their own kit;

Stanford

In addition, the following additional GENI-related campuses and sites may separately purchase the necessary equipment to build their own WiMAX campus deployment kits, and then deploy them with aid from the GPO and Rutgers WINLAB:

BBN Technologies
University of Wisconsin, 2nd site?
other?

5.4 GENI WiMAX Licenses

5.5 GENI WiMAX Buildout Issues

No Issue Who Opened Resolved Resolution Note
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. Current list: BBN Technologies (firm); University of Wisconsin, 2nd site (?); other? Mussman 12/09 - - We need this to be firm by 3/31/10, to be ready to place the order.
5.2 How to order additional kits: We need to understand how to order the key components from NEC for a WiMAX campus deployment kit, both BofM and process. Rangarajan 2/10 - - We need this by 3/31/10, to be ready to place the order.
5.3 Research plans: Each project should review and update their plans for research, which can help drive design of kit and software. All - - - -
5.4 Spares: Currently, there are no designated spares for hardware that could fail: ODU, NW INTFC card or CHC card. What will we do if we need a spare? Rangarajan, Mussman 2/23/10 - - Need to check on NEC America budget for spares. Need to check on GPO budget for spares.

6. WiMAX Campus Deployment Kit

Fig 1-1) System Overview

6.1 Configuration

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?

6.2 NEC Hardware

Fig 1-2b) NEC BTS IDU, ODU and Antenna

6.3 -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.

6.7 Control and Management

Fig 1-5) Control and Management

6.8 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?

6.10 Kit Hardware, 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.

Kit Ordered Received Integrated Delivered Where Note
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 ?
