DTE Power Via MDI – 5 Criteria
`
`1) Broad Market Potential
`
`- Broad set(s) of applications:
`The following areas have been identified as potentially benefiting from power over MDI:
`•
`IP Telephony
`• Web Cameras
`• Wireless Access Points
`•
`Industrial Automation
`• Home Automation
`• Security Access Control and Monitoring Systems
`• Point of Sale Terminals
`• Lighting Control
`• Gaming and Entertainment Equipment
`• Building Management
`
`- Multiple vendors, multiple users.
`At the Call for Interest, 44 individuals from 34 companies supported this initiative, and 20
`organizations stated an intention to work on the development of such a standard. Support for
`power via MDI has been requested by TIA/EIA TR-41.3.4 and TR-41.4. IEEE 802.11 has
`expressed interest in such a standard. There are existing proprietary and other potentially
`conflicting standard solutions (e.g. I.430) in the market. The goal of the standard is to reduce the
`issue of interoperability in the powered LAN market.
`
`- Balanced cost, LAN vs. attached stations.
`For some markets the cost of providing AC power is a barrier to the use of a LAN solution.
`Having a standard MDI power source brings a balance of cost in providing power to a level
`consistent with the silicon and applications.
`
`2) Compatibility with IEEE Standard 802.3
`
`- Conformance with CSMA/CD MAC, PLS.
`It is our intention to be compatible with 10BASE-T and 100BASE-TX UTP, and do no harm to
`1000BASE-T, with no changes to the existing MAC.
`
`- Conformance with 802.2.
`There will be no changes to the current MAC client interface.
`
`- Conformance with 802 Functional Requirements.
`The proposed standard will conform to the 802 Functional Requirements.
`
`3) Distinct Identity
`
`- Substantially different from other 802.3 specifications/ solutions.
`No existing 802 standard or project addresses power.
`
`- Unique solution for problem (not two alternatives per problem).
`Only a single powering technique will be standardized. There will not be multiple alternatives.
`
`- Easy for document reader to select relevant spec.
`The specification will be added to the 802.3 standard as a new clause.

` 4) Technical Feasibility
`
`- Demonstrated feasibility, reports - - working models.
`A draft for P802.9f proposed methodologies that would address powering via an MDI. There are
`existing proprietary solutions in the market; however, they may not meet all of the objectives of
`this proposed project.
`
`- Proven technology; reasonable testing.
`This will be addressed as part of the project.
`
`- Confidence in reliability.
`This will be addressed as part of the project.
`
`5) Economic Feasibility
`
`- Cost factors known, reliable data.
`This will be addressed as part of the project. Power supply and distribution are mature
`technologies and the cost factors well understood.
`
`- Reasonable cost for performance expected.
`The objective is to lower the total cost of ownership. This will be an enabler to numerous new
`classes of “network appliances.”
`
`- Total installation cost considered.
`An objective is to lower the total cost of installation.
