IoT Analytics
Research, a market research
firm, predicted [1] a yearly 22%
growth rate in the global IoT market
over the next three years. By 2025,
the installed base of active IoT gateways
is expected to be 27 billion,

not including laptops, tablets, and
cellphones. In this projection, gateways
are counted, not every sensor.
Therefore, the number of connected
radios in 2025 is going to be higher
than the forecast of 27 billion, perhaps
much higher. The IoT market is
likely to continue growing past 2025,
but this growth rate is unsustainable
with today's technology. This article
discusses three limitations to IoT
market growth: power, cost, and performance.
Examples of innovations
needed to enable the predicted market
growth will be presented in each

area. At the end, a prediction for IoT
wireless nodes in the coming decade
is presented.
IoT Wireless Node Power
Consumption
The human population aged 15-65
is approximately 5 billion people. By
2025, with 27 billion IoT gateways,
on average, each one of these people
will need to change or charge batteries
for all of the nodes connected
to at least five gateways. If each gateway
has two end nodes with one
year of battery life, then each person
