German cable operators told to tighten up
Interference is your problem, not ours
A German court has ruled that any interference to cable TV services is the cable operator's problem, and can't be used to delay the Digital Dividend auctions in the country.
The Cologne Administrative Court rejected an action brought by Kabel Baden-Wuerttemberg which sought to delay the auction. The cable operator claimed LTE services deployed around 800MHz could interfere with cable TV operations, but the judge responded that it was up to the operator to ensure that no interference occurred.
The potential for LTE signals to interfere with cable TV is under investigation within the EU and has been demonstrated in laboratory conditions, though the real-world impact is unknown. Cable operators often use the same frequencies as analogue TV did, only stuffed down a cable rather than sent through the air. The robust nature of both signals prevented any interference despite the cable operator's notoriously leaky infrastructure.
But with Vodafone, Telefonica and Deutsch Telekom (all of whom are committed to LTE technology) already signed up to bid, it's not going to be long before LTE services start filling those airwaves.
Which is what's got the cable operators concerned - interference could force them to shift frequencies or harden their kit to prevent the interference, and they'd like to hold the auction until that's been assessed.
But the ruling makes that unlikely, much to the delight of local amateurs who are hoping that the hardening will also clear up leaks around 145MHz which have been annoying them for years. ®
When I rolled out my company's Munich office 4 years ago, I was informed that most DE companies used shielded Cat7 office ethernet cabling due to very severe RFI compliance requirements. Sorta surprised that the cable operators didn't deploy the same shielded stuff...
You don't know german cable companies
German cable companies are evil. They usually don't take any responsibility. In most cases, if you have a technical problem, they either tell you to "go to your landlord" or they just stop talking to you.
At least the largest one of them works on old equipment which is slowly crumbling appart. It's not unusual that whenever there is a light rain shower at the downlink station, the picture goes away, beeing replaced by a nice FUBK test-pattern labelled "Deutsche Bundespost". (that's the pre 1995 name of the cable operator back then) I've seen cases where there was constant FM-sparks in certain easy to recieve television stations for months, but they just didn't bother to fix their equipment.
Now this is at least a small victory for the consumer. A court has decided that the cable operators need to maintain their networks.
Well it is entirely the cable companies responsibility.
If LTE is licensed to use certain frequencies and the cable company isn't and the cable company happens to use some of those frequencies inside their cables. So this means it is the cable company's responsibility to not cause interference and their responsibility to deal with any interference.
After all LTE operating at a licensed frequency is NOT interference. It is proper operation.
