4. System Engineering

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

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

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.

5. GENI D&P WiMAX Infrastructure Buildout

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:

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

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

Rutgers, WINLAB
NEC Labs America

The WiMAX Kit Project (1753) is purchasing and supplying WiMAX campus deployment kits to these campuses:

Rutgers, Bush Campus
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?

6.2 NEC Hardware

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

6.3 -48VDC Power

Both ODU and IDU are, as are most other telecom systems, powered by the -48VDC power source. There are two possible configurations:

  • Single unit -48 VDC power supply that is powering both ODU and IDU
  • Two independent -48 VDC power supplies one for each of the units

The second solution has an advantage in deployments for which 110V AC circuit is already available at the chosen outdoor installation location. Rated power requirements are 8.4A for IDU (in full configuration with all 3 sector boards) and 4A for ODU. One possible choice of power supplies is Mean Well:

Power Feed Connections

As outlined in the NEC Installation Manual for Base Station (IMN:BS) the two unit are using the following:
