What’s wrong with 3G/LTE? Why low-cost/power is important 10s of billions of connections of very low value
remote sensors must be wireless, must be battery operated
Why cellular cannot deliver the connectivity high cost spectrum
high cost terminal hardware
high cost base station hardware
high cost deployment (vs off-grid)
high cost operation (spectrum amortisation / ARPU)
high power terminals because of sophisticated processing
high bandwidth protocol demands processing power
high power terminals because of network traffic
high power terminals because of data packet overhead

Smart Cities• City Wide sensor networks – the backbone of the city
• Parking and traffic management – direction to empty spaces
• ‘Smart’ Litter bins – emptied on demand
• Environmental monitoring – traffic flow control to reduce CO2
• Street Light optimization – activated by movement
• Electric Vehicle (EV) re-charging points (EVSE)
• Road condition monitoring – variable speed limits, ice gritting...
• Integrated traffic management – flow and congestion

Some general trends in cellular
Cost per chip ~ 2x per generation Often a mix of complexity and royalty costs
Power consumption growing per generation Moore’s Law improvement more than offset by added
complexity Bill of materials may grow even faster than 2x
MIMO antennas, multi-core processors, extra bands, etc Becoming more data-centric
2G voice with data added later 3G a mix of both, circuit and packet switched 4G doesn’t fully support voice (being worked on)
Reducing number of networks Consolidation, network sharing, outsourcing to same partner

IoT barely works on 2G
Requirements ~$2 per chip Battery life up to 10 years Range of 5km+ with indoor penetration
2G ~$5 per chip Battery life up to months with care Range of 3km with indoor penetration
4G ~$50 per chip, might fall over time Battery life of days Range probably less than 2G

Weightless design principles
Designed for machines Very low overhead on small packets Almost no signalling traffic Features like multiparty messages and “alert quashing”
Designed for white space (but will work elsewhere) TDD Smart hopping, nulling and other interference mitigation
Ubiquitous coverage implies a cellular architecture Deep indoor coverage with low transmit power implies spreading to
extend range Entirely software-based core network to lower cost

Why Weightless?
No existing standard in this space Technically very different from existing technologies Commercially very different from existing value chains No other technology will enable tens of billions of connections
