4 edits | You need to understand something... Satellite use of this band is a SECONDARY SERVICE. The primary users of this spectrum are the microwave towers that used to be on top of every large telco central office. Most of these are gone (thanks to fiber) but the FCC has NOT re-allocated this spectrum because many towers still do exist, particularly in areas where installing fiber is not cost effective. I just went past a HUGE installation in the California high desert last week.
What this means is that WiMax and satellite use are considered co-secondary users of this band-along with others as well.
Look on the bottom of your cordless telephone. See where it says: "Use of this device is subject to the following two conditions: 1. This device may not cause harmful interference and 2. This device must accept any interference received, including interference that may cause undesired operation"
Part 1 of that statement means harmful interference to the primary user (telco microwave). Part 2 applies to the secondary users (satellite, WiMax and other secondary users). Sometimes this interference causes: "undesired operation"- meaning that the device doesn't work!
In simple terms, secondary users must not interfere with primary users whatsoever, and CAN (and do!) interfere with other secondary users.
So, bitch all you want to satellite users-you have no recourse whatsoever! |

In simple terms, your quote is for unlicensed spectrum and does not apply to licensed spectrum. Why-Max is currently available only in licensed frequencies. |

In simple terms, your quote is for unlicensed spectrum and does not apply to licensed spectrum. Why-Max is currently available only in licensed frequencies. I'm talking about licensed services. Again I say, Satellite and Wimax-while both licensed services are SECONDARY to the primary user of this band, which is telco microwave.
As secondary services, it it permitted for them to interfere with each other (but NEITHER can affect the telco microwave)-that is what SECONDARY means!
Also, though satellite transponders and uplinks are licensed, receive only dishes are NOT! You can FCC register them under certain cirsumstances, but that only applies to very LARGE dishes, and it still does not guarantee flawless operation.
By the way, this is why most newer satellites now operate on the Ku satellite band, because satellite is the PRIMARY user of that band. |

Your opinion sounds very logical, but it would be interesting to see an actual FCC regulation of the frequency band in question that confirms that satellite is primary and every other license issued in said band is secondary. The label on the bottom of a cordless phone is not relevant to the 3.x Ghz licensed band. |
