WiMAX• Exposed all controllable parameters through API• Removed all default IP routing, simplified ASN
controller*• All switching purely based on MAC addresses• Implemented the datapath virtualization and VNTS
shaping mechanism in click/openvswitch for slice isolation
LTE• Exposed all controllable parameters
through the same REST based API• Implemented the datapath with
openvswitch• Current development: ePC
replacement with open source (i.e. simplification/elimination of LTE control protocols)

Program Experimental License
• New type of experimental license: • “Establishes program experimental licenses for colleges and universities
with an accredited graduate research program in engineering, research laboratories, manufacturers of radio frequency (RF) equipment, manufacturers that integrate radio frequency equipment into their end products and health care institutions to allow broad experimental authority under a single license.”
• Eligibility– ABET accredited college or university with a graduate research
program in engineering – A research laboratory (not limited to federally funded)– A hospital or health care institution (non-clinical trial testing only)– A manufacturer of RF equipment or a manufacturer that integrates RF
equipment into its end products.

• Special Requirements for:– Restricted Frequency Bands– Critical Service Bands– Federal Spectrum
• N (five?,ten?) days before each experiment*:• “a narrative statement describing the experiment, including measures to avoid
causing harmful interference to any existing service licensee in the proposed band”
• “contact information for the researcher in charge of the experiment;• contact information for a “stop buzzer” point of contact – a person who can
turn off the equipment if interference occurs”• “technical details including frequency, power, bandwidth, modulation, location,
number of units, etc.”• “for commercial mobile, emergency notification, and public safety frequencies,
a list of potentially affected licensees”

• Rules have officially become effective as of January 14, 2016.
• But: new forms and reporting WEB site are not yet up (will take a few more weeks according to “reliable sources”)
• Perfect fit: intended to foster innovation• Has significant implication on wide area
experimentation especially with SDRs and non-traditional RF front-ends.
• (the rule also includes two other experimental licenses: the Medical Testing License and the Compliance Testing License)
