Hi All,

I'm using the beocom 6000 w/ 1no. of new PSTN repeater, I also have the old beocom 6000 which was a stand alone on a seperate line. I find the old beocom 6000 actually work much much better then the new one, distance is far greater. for the new beocom 6000, due to the line always cut off while I was using it, so I've add in 2 more repeaters (total 3 repeaters), but still I sometimes get cut off, B&O guys did come to my place and to see if there is anything that can do, but the result is only slightly better. I'm wondering is there anything that I can do to get better reception for the new sets of phone. (FYI, I use both the new / old Beocom 6000 at the same environment, there is cord wall, other electronic stuff in between but the old one works perfectly fine). The B&O guys did told me the old repeater actually work better then the new one...!!! interesting...., so I was also wondering is there any places that I can get the old repeater to try out or alternatively what else can I do in order to get better reception.......

 Thanks for your help.

Fc,

Let start by welcoming you to Beoworld.

I am surprised you need three (3) repeaters, unless there is a very large distance between base and phone.

What are the distances between base and repeater and phones ?

Generally speaking, the signal is normally good over distances up to 100 metres unless there is RF interference normally from things like Wi-Fi routers near the base or repeater. I have Beocom 6000 (Mark I & Mark II) working at a distance greater than 100 metres without a repeater and they work perfectly.

Assuming your distances are not greater than say, 150 metres, then I think your problem is being caused by interference.

Hi Keith,

Thanks for the quick reply.

 Actually, the distance between the base from each repeaters isn't that far. The base and the tramsitter is located at the G/F. Then there is square looking repeater in the kitchen, 1 in the study room which should also cover the master bedroom area too. 1 repeater located upstair. below is what I think the distance should be.

- FYI, I live in HK, G/F is 200 s.m. and upstair is 120 s.m.

- Base unit is fairly close to the staircase and to the repeater upstair ( base > upstair repeater = 5 meters MAX)

- Base unit from the kitchen repeater is 15 meters MAX, there is a cord wall in between. And if I go further down to the maid's room, possibly the line could get cut off. The kitchen repeater is located in centre of the kitchen and the maid's room. In fact, at once I was standing right in front of the kitchen repeater and the line still got cut off, whereas I can still see the red light is on from the repeater.......

- Base unit from the study room repeater is also around 15-20 meters, in between that, there is only some full height cabinets, no cord wall or whatsoever. And the distance between the study room repeater to master bedroom phone unit is only around 6 to 7 meters.

As said, I do have the old beocom 6000 which was a stand alone unit at the study room, and if I take the phone and walk to living room, kitchen....singal is still pretty good, so I'm a but surprise that the new one can't plus all these add on repeaters.....!!!

I do have Wi Fi all round for both downstair and upstair, AV eqpts......etc...etc. But as said, it doesn't affect the old beocom, and why should it interfer with the new system, am I correct ? 

 Thanks you so much for the help......

PS: Btw, are there any way that I can get the old repeater ? Coz some ppls did say they actually work much better then the new one......for some reason I don't know why...

Fc,

It is clear to me from your comments that your problem is caused by co-frequency interference or you are living in a "Faraday Cage" which will normally dramatically reduce the signal range. Whatever the interference is or if you are living in a Faraday Cage, it effectively acts as a signal killer. By adding repeaters all you have done is try and produce a signal strength greater than the interference or bypass the Cages effect.

Whilst the RF chips in the Mark I & Mark II handsets are different as well as the repeaters, the range difference between the two versions is small and not normally noticable.

I have six Beocom 6000's (Mark II) which work perfectly even at the bottom of my garden or sitting in my car in the drive. My base station is on the ground floor and my office is on the second floor which is at least 30 metres line of sight through 2 floors without repeater.

So, lets ask a few questions and make some comments:-

1. Do you live in a modern concrete building ?
2. I suggest you power down all WiFi equipment, microwave ovens and any other transmitting equipment in your home and test again.
3. As you are in Hong Kong, is your home within 300 metres of a mobile phone transmitter ?

NOTE: A "Faraday Cage" is effectively a metal grid which could be in walls which is earthed which creates an environment which dramatically restricts electromagnetic radiation. You can get this type of cage if you live in a building where the walls, floors and ceilings are made of reinforced concrete

Hi Keith,

Thanks for the info, and yes, I do live in a concrete building w/ reinforced concrete. Very much likely b'coz I've too much cabling /wiring in the walls that create interference. possibly and very much likely it will have to do with the wi fi and or microwave as well. But do they transmit any signal while they are not even in use ? So I guess more likely I will test it on the wi fi first. as I feel very much likely it was that cause the problems. But let say if it's the wi fi, then what can i do, my point was I cannot keep the wi fi off at all time just for the phone, right ? somehow I need to find a way to balance the 2 things.....

Fc,

If it turns out to be the WiFi then there is many possible solutions. First you should note that WiFi in Europe has 13 channels and in the US 11 channels, so you would start by changing the channel number the router uses. This is done by going into the Admin account on the router using a web browser.

Once we have found out that actual cause of the problem, then we can look for a solution. What make is your WiFi router ?

Hi Keith,

The wifi router is 3com, and cisco (a blue box but don't know the model), a JUNG automation system which control all the lighting, and a crestron touch screen remote which run on wifi plus lot of other remote control thingee. I can talk to my I.T. guys to change channels and test it this way, of coz if the interference was caused by the wifi.

You've been very helpful and thank you, will get back to you for the results.

regards,

Fc
