Hey everyone,

I was doing an install today (900mhz SR9/133c)and I had to call the office. The customer let me use their cordless VTEK 5.8Ghz phone. They commented that it has been very "staticy lately" I was in winbox, and the minute I hit the talk button on the phone the SR9 link went down. I ended the call and the link was up.....in utter disbelief I tried several times and confirmed that it was the phone causing this problem. Now, next door I have a customer with a 900Mhz set-up as well, so that explains why they are getting static on their phone..... fortunately, it had not shutdow the neigbors link, but I'm sure it has effected their performance.

Now, I've experienced these problems with baby monitors and other 900Mhz phones, but a cordless phone at 5.8??

Anyone have an explaination?? I'm a little blown away about this one. MIKE (uBNT) Have you seen this??

Many 5ghz phones also use 900mhz...

Maybe it's really a 900MHz phone with the wrong label?

Again, many 5ghz phones use both 5ghz and 900mhz to operate. It's common knowledge.

Yes, I ran across this awhile back too. V-tech labels their phones as 5.8 ghz, but you have to dig very deep to find out that they actually use 900 mhz also. They were advertising it as "a long range phone with 5.8 ghz quality." which we can all translate the marketing BS to mean "we'll only use 5.8 ghz when you're really close, otherwise we're going to use 900 mhz so you can actually roam around"

I think it's dumb.... if it uses 900 mhz, it should say so on the faceplate..... nothing we can do though....

We usually tell our customers to use DECT 6.0 phones, that is one of the main things we check out on an install no matter what type of a phone it is.

Best of luck
