Massive Connectivity Use Case
Example: Home automation, remote patient
monitoring, fleet management etc..
Requirements:
•
•
•
•
Low cost
Low energy
Massive numbers
Long range
5G will bring – ultra-low cost, ultralow energy, wide coverage
Mission Critical Connectivity Use Case
Example: Autonomous vehicle, remote control in
mfg, medicine (remote surgery) etc…
Requirements:
• Ultra high reliable
• Ultra low latency
• Ultra high availability
5G will bring: Ultra-high reliability,
ultra-low latency, high security network.
Combination of ultra low latency and
high reliability is not achievable with
current wireless technologies.

IoT Applied Courseware Objective
– On Mar 1, Keysight will introduce IoT Fundamentals and Systems Design applied
courseware targeting university educators who plan to offer IoT Design courses.
The courseware may also be used to supplement existing IoT curriculum.
– Keysight's ready-to-teach IoT Applied Courseware is designed to:
• assist educators to quickly set up new courses on the current mega trend in
the industry,
• prepare industry-ready students,
• “future engineers” will gain valuable learning knowledge on current IoT
challenges and hands-on experience with various Keysight instruments (new
1000x scopes, DMMs, Spectrum Analyzer, DC Power Analyzer, etc).
– Keysight will also be introducing the upcoming 2 nd phase of this launch - IoT
wireless communications, IoT sensors and power management courseware –
sometimes end of the year.

What are problems Educators facing today
Too many tasks
Academic Scientists are trying to juggle many different
tasks, all are important, and only one of these is
teaching science to undergraduate students
Rising student expectations
Students are now paying more for their studies and expect a more lucrative return on
investment, whether in academic quality, employability or the facilities offered to them.
University strategies become more flexible in order to best attract students in a highly
competitive market.
Funding
Funding for education has become more difficult to access since
2011. Availability has moved away from block grants, and is now
spread more thinly, and open to intense competition.
Technologies
As technologies changes everyday, its hard for educators to
keep up with teaching the latest technologies
