Today’s connected enterprise relies on mobility for everything from
guest services to tracking user behavior. As trends in IoT grow, the
requirements of your network morph to a mobile-first environment
where availability, security and quality are key to delivering reliable
services with appropriate security from today’s threats.
IoT devices and networks have unique needs, often in contradiction to
traditional WLAN endpoints.
The needs are discussed and contrasted in terms of wireless Quality,
Security, and Availability.

3. #RSAC

Trends in Traditional WLANs
A two-minute overview to set the stage

4. Traditional Wi-Fi needs for quality, security, and
availability are tailored to the current endpoints and
applications.
• Quality:
Bandwidth, Speed, Capacity,
Capability
• Security:

Recursion: Trends and Cycles in
Computing
A brief look at the cyclic nature of technology trends and their
impact on IoT

10. We’ve Been Here Before…
Heavy -> light -> heavy
(applications, wireless, endpoints)
Centralized -> distributed -> centralized
(computing, clients, intelligence)
Divergent -> converged -> divergent
(RF, medium)
50-year progression to inter-
connectedness

11. #RSAC
Other Current Tech Trends Affecting IoT
Consumerization
proliferation of connected devices for home, personal use, quantified
self- reflected in commercial applications, monitors, sensors
Smart-things
not only Internet connected but usually machine-to-machine with
peers and central analytics, drives data, cloud, privacy/security
changes
Big data and analytics
IoT will be driving the bulk of data for big data analytics, IoT and big
data will be symbiotic

RF Spectrum and History
Let’s look
at specific
RF

17. In years past, we’ve taken RF technologies and tried to CONVERGE them
to 802.11 standards, specifically around the 2.4 band.
Now, with the discrepancies in needs of IoT and enterprise WLANs, we
see the RF DIVERGING again.

What’s on the horizon to address the unique and divergent needs
of RF including 802.11ah (HaLow), 802.11af, and 802.11ad

22. #RSAC
3 Emergent Wi-Fi Technologies Related to IoT
802.11ah HaLow
for low data rate, long-range sensors and controllers
802.11af White-Fi
for similar applications to 802.11ah, uses unused TV
spectrums instead of 2.4 GHz or 5 GHz bands for
transmission
802.11ad WiGig
for multigigabit speeds and high-performance
networking (not new)

take to your organization for discussion

34. #RSAC
Your IoT Take-Aways
IoT isn’t just “more connected stuff”.
IoT devices have different fundamental needs from a network perspective.
Many IoT needs are in conflict with traditional wireless endpoint needs, so
prepare for divergent RF.
Regardless of industry,most organizations will be dealing with IoT soon, if not
already.
Successful IoT most likely requires a redesign of wireless, not just an up fit.
Get inter-department resources to collaborate on early planning and help
identify trends in your industry or organization.

35. #RSAC

36. #RSAC
Get Ready to Support IoT
Research & prepare for divergent RF standards in the environment
Expect mass or bulk endpoint deployments
Expect smaller form factors than traditional endpoints
Start rethinking wireless security today
Create a strategy for managing (or at least monitoring) other RF
spectrums
Begin planning wireless networks for endpoints with very different
needs
Budget additional training for staff ***
