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:

1. providing campus-wide GENI wireless coverage for opt-in users;
2. 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.

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.

• UEs
  • COTS UE on Orbit Node
  • Mobile Phone (Under Construction)
  • SRS LTE Soft UE (Under construction)
  • OAI LTE Soft UE (Alpha, under construction)
• eNBs
  • Amarisoft
  • Airspan
  • OAI
    • eNB in ORBIT
    • Split eNB, RRH over Ethernet
    • Split setup using GENI
• 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 ​link
• Known working configurations
  • Netgear UE, Amarisoft eNB, Amarisoft EPC
  • Netgear UE, Airspan eNB, Amarisoft EPC
  • Netgear UE, OAI eNB, Amarisoft EPC
  • Netgear UE, OAI RRH eNB Split, Amarisoft EPC
