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.
