Power over Ethernet (PoE)Technology adoption in the Marketplace
Endspan and Midspan Power over Ethernet Technologies are
being implemented around the world in Networks large, medium
and small. There are many new applications driving the growth
of PoE. Since the two Technologies are often used to solve
fundamentally different powering issues,
End Users often choose one Technology type over the other.
The information was compiled by a prominent market research
group, Venture Development Corporation. Their annual
report entitled "Power over Ethernet: A Global Market
Demand Analysis" is made available once each year
to participating organizations.
Some key metrics from the VDC report include actual
and forecast data for PoE implementation, Endspan vs. Midspan,
in 2006, 2007 and 2008. Endspan growth is steady over the
3 year period with 140M Ports in 2006, 175M Ports in 2007
and 205M Ports in 2008 (worldwide), Midspan growth is also
steady with 4.95M Ports in 2006, 8.1M Ports in 2007 and 11.75M
Ports in 2008. The ratios of Endspan adoption to Midspan Port
adoption are as follows: 28 to 1 in 2006, 22 to 1 in 2007
and 17 to 1 in 2008. The data clearly shows that while there
is strong growth in both the Endspan and Midspan categories,
Midspan Port adoption is growing at a faster percentage
rate going forward. One way to understand the forward
growth and on-going demand for Midspan PoE is to look at the
list of devices, which are anticipated to become ready for
PoE in the next several years. While the beginning of the
PoE life cycle has seen demand based on powering of mostly
IP Phones and Wireless Access Points that take power as specified
by the IEEE 802.3af PoE Standard, the future of applications
and End devices for PoE takes a much broader approach.
The VDC Survey asked numerous Manufacturers of products
across many technologies to rank new products which could
be made ready for PoE, though not limited to the IEEE Standard
style PoE. The need for 24v, 12v or 5v would rule out powering
by Endspan Switches which are only capable of IEEE standard
48v and 15.4 watts maximum. Midspan PoE is capable of mix
and match voltage and protocol styles and will be preferred
for many of these new applications including: IP Based Network
Security Cameras, RFID Tag Readers, IP Thermostats, Print
Servers, Bar code Scanning, Alarm Systems and Sensors, Security
Access controls including badge readers, Smoke detectors,
Stage lighting, Industrial Clocks and time keeping, Lighting
controls and In-Flight Entertainment systems.
Some additional insights from VDC are that these
new PoE enabled End devices will continue to spur growth of
both Endspan and Midspan PoE techniques well into the future.
End users have already accepted that PoE, as with the Ethernet
medium itself, will not cause data degradation or loss of
integrity whether enabled into an Ethernet Switch or injected
with a Midspan Hub onto the Structured Cabling System. VDC
sees the following industries as benefiting most from the
uplift in PoE adoption; Power Supply, UPS, Midspan PoE Hub
and Endspan PoE enabled Switch Suppliers. The other market
segment gaining value due to PoE are all the Manufacturers
making End devices which can now accept PoE power as End Users
are much more likely to choose those brands over similar products
without PoE functionality.
Conclusion
The marketplace for both Endspan and Midspan PoE is healthy
and will continue to grow in future years. This growth is
based partly on a wide range of additional new products coming
which will be powerable via PoE technology. Many of these
devices will be better suited to Midspan powering due to variances
in voltage or wattage requirements or the smaller number of
units required on the End User's Network. LAN Power Systems,
as a major technology innovator in the PoE market, is committed
to long-term participation and continual development of new
PoE products which incorporate the key elements of Flexibility,
Simplicity and Value.
