What is Iot?
Internet of things(Iot) is a
system of interrelated
computing,digital or
mechanical devices with
unique identifiers (uid) that
has ability to transfer data
over the network with or
without human intervention.

3. Why Iot?
Iot connects all potential
objects to interact over
the internet and to
provide comfort human
life.Moreover it improves
efficiency and optimizes
battery life.

8. ➢Low-energy bluetooth:
This technology supports the low-
power, long-use need of IoT function
while exploiting a standard technology
with native support across systems.
➢Low-energy wireless:
This technology not only reduces
power consumption but also extends

9. ➢Radio protocols:
Zigbee, Z-wave,thread are radio
protocols
for creating low rate private area
network.Though they are low power
sourced they offer high throughput.
➢LTE-A:
LTE advanced provides an upgrade to
LTE technology not only by increasing
