Problems and challenges

• Too early introduction of products– Missing knowledge of communication medium

• High expectations (in profit)

• Competing technologies (WiFi, DSL, WiMax, etc.)– Time made this problem worse!

• Delay in standards and regulations– Hesitation in investments

• Interference problems– Radio amateurs, astronomy, basic (secret) services

• Conservative utilities: „we sell energy“

introduction of products

„we sell energy“

who wants to disprove an idea that can change the world and fatten your bank account at the same time?

High expectations (in profit)

GOOD

PLC Proposal (QPk)(Derived from FCC limits using 33dB/dec)

Guelleman Limit (QPk)

BBC Proposal (Pk)

- For comparison purposes limits scaled to 3m using 20dB/dec except PLC proposal 33dB/dec - For EN55022 the magnetic field is calculated from the telecom port common mode current limit using: H = I / 2.pi.r where r = 3m- H-field limits converted to E-field using the far field correction of 51.5 dB
