ORBIT Tutorials
Basic Tutorials
If you are new to the ORBIT testbeds, these tutorials will give you an introduction to the ORBIT testbed, its capabilities and its operations.
- Brief tour of the Testbed - the tutorial that briefly describes the ORBIT Testbed, its system architecture and its hardware and software components.
- Basic testbed operations and node management - overview of basic OMF commands and usage examples.
- First Experiment: the "Hello World" Example - a simple wireless "Hello World" with one sender and one receiver.
- How to post-process the measurements
More detailed information and references can be found either on the ORBIT Documentation page or on the OMF project pages.

Bluetooth and ZigBee Tutorials
WiMAX and LTE Tutorials
Wide area network experimentation in ORBIT currently supports two types of wireless technologies: WiMAX and LTE. Both technologies, in addition to devices deployed in various domains of the testbed, are also deployed on two Rutgers University campuses as part of GENI 4G deployment addressing the two key research issues:
- providing campus-wide GENI wireless coverage for opt-in users;
- offering programmable wireless networking capabilities
While initial focus was on developing and deploying wide-area wireless experimentation services with WiMAX technology, subsequent efforts were concentrated on introducing LTE. At the core of both types of deployment are technology kits typically consisting of a commercial basestation and PC-based controller running custom software that manages the basestation and performs layer 2 and layer 3 processing of client packets. More details on the 4G deployments can be found at GENI 4G pages. The most recent addition to the LTE experimentation capabilities are fully software-based (SDR) open (and closed) source implementations.

A wide variety of wireless experiments and tutorials are available for the GENI community. To try them out, please follow these Steps to access Wireless resources via GENI
Networking Tutorials
SDR Tutorials
The ORBIT testbed is home to a collection of software defined radio (SDR) device platforms including WARP, rtl-sdr, Ettus Research ( USRP (1), USRP N210, USRP X310, USRP B210), RTL-SDR, Nutaq ZeptoSDR and PicoSDR, and Avnet Zynq SDR. While most of the devices are in the grid, number of sandboxes are also equipped with SDR platforms and are suggested target for SDR learning and running tutorials (especially given that they are usually less busy than the main grid).
Most of the available SDR tutorials are using one of the three software platforms:
- Stand-alone C/C++ programs: USRP2 configration and OML data collection with wiserd, Observing the spectrum and transmitting wideband signals using USRP X310
- GNURadio: As the "workhorse" of the SDR community, GNURadio . The available tutorials that are mostly scripted with [OEDL (version 5.4)] are: Getting Started with GNURadio, working with USRP2 on sandbox3, data transfer using basic modulation or OFDM, MAC protocols adaption, creating custom GNURadio blocks for Nutaq platform and using a bot emulating primary user transmission
- Iris: The OFDM transport and ALOHA MAC tutorials
DSC and SDR based LTE
SDN
All ORBIT switches are SDN (OpenFlow) capable. SB9 domain is dedicated to SDN experimentation.

MobilityFirst Tutorials
The MobilityFirst project was started in 2010 with funding from the National Science Foundation's Future Internet Architecture (FIA) program as one of the four clean-slate architectures. The major design goals of this new architecture are:
- mobility as the norm (with dynamic host and network mobility at scale)
- robustness with respect to intrinsic properties of wireless medium
- trustworthiness in the form of enhanced security and privacy (for both mobile networks and wired infrastructure)
- usability features such as support for context-aware pervasive mobile services, evolvable network services, manageability and economic viability.
The design is also informed by technology factors such as radio spectrum scarcity, wired bandwidth abundance, continuing Moore’s law improvements to computing, and energy constraints in mobile and sensor devices.
The first three MobilityFirst tutorials have accompanying slide set. More information about MobilityFirst is available on the MobilitFirst site.
Smart Grid Network Management
Appropriate communication infrastructure and its management is essential for planned Smart Grid utilization. There is a need for work bench to test different communication management strategies. This emulator aims to provide framework for testing them with focus on different QoS strategies. Emulator is based on ORBIT for hardware provisioning and Mininet for network emulation.
