WiMAX (IEEE Standard 802.16) is an advancement of the WiFi (IEEE Standard 802.11) standard of wireless communication. It supports long-range wireless connectivity (of up to 30 miles) and faster data transfer speeds (ideally up to and well beyond 50 Mbps). Unlike !WiFI, which supports both client-to-access-point and peer-to-peer (ad-hoc) connectivity, WiMAX is not a consumer technology standard, and as such, WiMAX only supports client-to-base-station connectivity. Furthermore, because of the scope of WiMAX, equipment is generally unavailable for scientific experimentation. As part of the GENI project, WiMAX technology is being adapted into the ORBIT Wireless Test Bed to facilitate experimentation.


In order to perform research on WiMAX networking, it is first necessary to modify the equipment to allow for user-defined values to be submitted as network configuration profiles: also known as programming. The thrust of my research involves deciding which features of WiMAX are germane to experimenters and can be deemed mutable, and which parameters are core to the functionality of the equipment and must be left constant.


Currently, my research utilizes the Domain-Specific Language of the ORBIT Management Framework which encapsulates experiment description, execution, and data collection. Through experimentation, I hope to discover which parameters can be considered germane, and which can be safely restricted.


As I studied the WiMAX setup at ORBIT, I authored a pair of walk-throughs to enable other researchers to rapidly acclimate to our environment and enable them to proceed directly to experimentation.

Tutorial 1 is a primer on WiMAX drivers, utilities, and setup at ORBIT.
Tutorial 2 is a basic dummy OMF experiment using WiMAX as the connection medium.

  • Note: Some users have difficulty connecting to the domain due to a problem with the DNS provider. Such issues can be easily resolved by switching to a third-party DNS provider, such as Google or OpenDNS.
