This document summarizes Yue Gao's secondment with Weightless SIG from January to July 2014. The secondment aimed to explore standardizing academic M2M/IoT research and increase interactions among academics, standards bodies, and industry. Gao designed a novel antenna that increased the link budget of a Weightless M2M radio unit by 8-10dB compared to the original antenna. An international workshop on Weightless machine communications was organized with 60 attendees. Future work includes a second workshop and developing a TV white space testbed with robust spectrum sensing algorithms for M2M communications.

Outline
• Overview of the Weightless SIG secondment
• Activities conducted during the secondment
• The workshop organised
• Further work resulted

3. 3
Overview of the Weightless SIG secondment
• Objectives:
 To explore how academic research can be standardised, especially in
Machine-to-Machine (M2M) and Internet of Things (IoT) research areas.
 To increase interactions among academics, standard bodies and
industry.
• Supported by RCUK Digital Economy Theme - IT as a Utility Network
(ITaau)+, Call for Secondment (Call 2)
• Started from January in 2014 to be completed in July 2014

Weightless SIG standard
• Billions of M2M devices are expected to be connected, and a major
portion of them are through wireless connections.
• Weightless SIG provides the scope to realise tens of billions of
connected devices worldwide overcoming the traditional problems
associated with current wireless standards - capacity, cost, power
consumption and coverage.
• It is a new bespoke technology optimised for M2M that can become the
global standard.
 Low cost hardware and service.
 Excellent coverage
 Ultra low-power operations
 Secure and guaranteed message delivery
• Weightless Special Interest Group (SIG) was formed in late 2012, and 1st
Weightless technical specification was released in April 2013.
• Over 1600 industry members to date.

5. 5
From antenna perspectives to enhance M2M coverage
• We designed a novel antenna to replace an exiting one.
• Experiments integrating a M2M radio unit with antennas were carried out.
1000 packages were sent at different transmission (Tx) power levels.

8. TV White Space Testbed with Robust Spectrum
Sensing Algorithms for M2M Communications (Tic-tac)
Motivations:
• 50 billions Machine-to-Machine (M2M) devices to be connected,
ranging from smart grid, smart meters, to cars, to traffic lights, etc.
• White space spectrum provides a new opportunity as it is
plentiful, free, harmonised world-wide and has excellent
propagation.
• Weightless communication system required for low cost, long
battery life and vast coverage.

9. Spectrum sensingGeo-location database
Objectives:
• To develop a real-time TV white space testbed.
• To develop robust sensing algorithms for master white space devices (WSDs).
• To develop novel compact and wideband antennas for slave WSDs.
