Wide area network experimentation in ORBIT currently supports two types of wireless technologies: [https://en.wikipedia.org/wiki/WiMAX WiMAX] and [https://en.wikipedia.org/wiki/LTE_(telecommunication) 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 [https://www.geni.net/ GENI] 4G deployment addressing the two key research issues:
  1. providing campus-wide GENI wireless coverage for opt-in users; 
  1. 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 [http://wimax.orbit-lab.org GENI 4G pages]. The most recent addition to the LTE experimentation capabilities are fully software-based (SDR) open (and closed) source implementations. 

The menu on the right lists a number of tutorials covering basic operation of bot WiMAX and LTE deployments. 
 
 

LTE Tutorials are split into client (UE), basestation (eNB), and core network (EPC) sections.

* EPCs
 * Amarisoft
  * By default, the above tutorials use the Amarisoft EPC at mme.orbit-lab.org
  * By changing the MME IP address, an alternate can be used if desired.
  * This has a configured SIM card database
 * OAI
  * We do not yet provide a long-running OAI EPC, but there is a tutorial available at this [https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/HowToConnectCOTSUEwithOAIeNBNew link]
