Tasks completed• Get the base station install complete (moving to Plan B)

• Get yellow nodes installed and connected

• Connect WiNGS mobile gateway to new Airspan WiMAX

• Run a multi-site experiment (video) between UW-Madison and NY Poly U (currently to GEC)– Allow dynamic adaptation over video links (see demo)

• Integrate into classroom for Spring 2013

• Handsets

Planned next steps

• Get the ORBIT yellow nodes deployed– We are still waiting for them

• Handsets– Need help from the MVNO

• Demo of integration between GENI WiMAX and OpenFlow– Preliminary version has been completed

LTE Options

• Spectrum --- find remote locations that will have no likely future commercial deployments

LTE Options

• Spectrum --- find remote locations that will have no likely future commercial deployments

• That can benefit from experimental LTE

Hardware and software

• Picochip/Mindspeed

• Software --- some options exist
