Abstract
Comparison between Measured Data-Carrying VDSL2 Cable Radiation and Radiation Limits for Wire-Line Telecommunication Networks
Highlights
A rapid development of communication systems and their successful application in the communication market have deeply affected people's habits and living standard
Measurement results have shown that the radiation from the cable is approximately 6 dB above limits proposed by the ECC/REC(05)04 Recommendation, which could cause intolerable errors in radio signal reception, disabling radio service to operate as intended
In this paper the radiation from the TK59U-xDSL cable when VDSL2 profile 17a technology is used has been measured and analyzed with the aim to evaluate whether the proposed radiation limits are met or not
Summary
A rapid development of communication systems and their successful application in the communication market have deeply affected people's habits and living standard. It is important to limit radiation from wire-line telecommunication networks, especially in order to protect critical services where such radiation can directly affect the safety and security of human life. To restrict such interference to radio services various limit values and mitigation techniques have been proposed, either by international institutions. To avoid possible contamination of the frequency spectrum and enable the coexistence of DSL technologies with other radio services operating in the same frequency band, ITU proposes to use interference mitigation techniques (e.g. notch filters) as a solution in case radiation levels are not met.
