Current Eco-System
Sigfox (market leader in Q1 2014):
technical: sub-GHz, UNB, very long range, one-way
business approach: operator, yearly license fee; Intel Ventures €10 million VC
On-Ramp:
technical: 2.4GHz ISM band; “Random Phase Multiple Access”; 170dB link budget
business approach: equipment provider mainly; Managed Service SLA possible
Cycleo (now Semtech):
technical: sub-GHz, CDMA-based, long range
business approach: equipment provider
Neul:
technical: initially TVWS only; now shift into other bands too (notably licensed!)
business approach: originally only equipment; now SLA possible

Availability = coverage, roaming, mobility, critical mass in rollout, etc.
Reliability = resilience to interference, throughput guarantees, low outages, etc.
