Signal Leakage Patrolling at 700 MHz (Part Two)

By H. Mark Bowers – I believe this exercise raises the issue of how one is to perform accurate field strength measurements at higher LTE frequencies, where there is a low-level leak from the HFC plant (especially QAM), while LTE signal levels comprise the bulk of the spectral energy and overall field strength.

Signal Leakage Patrolling at 700 MHz (PART ONE)

By H. Mark Bowers – Newer leakage detection systems are now available that measure at dual frequencies. While {the} present FCC required leakage detection frequency range remains in the 108 MHz to 137 MHz aeronautical band, measurements at higher frequencies can be revealing and may eventually be required

Scalar Testing (Part ONE)

By H. Mark Bowers – In my last column we examined digital QAM testing requirements under present FCC Part 76 Rules and ANSI/SCTE 40 2003 Requirements. In this column we’ll begin an examination of scalar testing and why it’s important in the HFC network.

DOCSIS 3.1 Beating Expectations, Working and Ready for Service Now

By Brady Volpe – Some operators are saying that the performance of DOCSIS 3.1 is proving to be better than they had expected. Those who are deploying DOCSIS 3.1 in production systems are happy to see that these modulations are not only working, but actually working in areas where they did not expect such high performance.
