| 1264311 | 2012-03-11 08:02:00 | Just curious. I was talking to someone from Telecom who was doing a survey and we happened to get onto broadband cutting out when phone was used. They mentioned that sometimes a cordless phone will do this cos the frequency could be the same as broadband? Is this true and if so what frequency phone should it be to prevent it. | Clod (7853) | ||
| 1264312 | 2012-03-11 08:25:00 | Might be talking about wireless modems/routers. Since some are 2.4 ghz. So, are some phones | Speedy Gonzales (78) | ||
| 1264313 | 2012-03-11 08:25:00 | Yes if you have a wireless network. Usually easily fixed by changing the frequency. | CliveM (6007) | ||
| 1264314 | 2012-03-11 08:31:00 | Cordless Phones, or not having a filter on all your phones are possibilities. Have heard of Microwaves doing it too. | Alex B (15479) | ||
| 1264315 | 2012-03-11 08:41:00 | Yeah make sure you have a filter on every phone/device that is connected to your phone line, the filter must be the first thing plugged in as well. | icow (15313) | ||
| 1264316 | 2012-03-11 09:13:00 | From Telecom. top I occasionally experience a reduction in signal clarity/ quality, why is that? And how can this be reduced? Cordless phones operate by broadcasting the voice signal on a spectrum from the base unit to the cordless handset. Typically the spectrum used for the voice signal is largely unregulated [or is in the public domain], and therefore any number/ type of devices can operate across the spectrum e.g. garage door openers, baby monitors, wireless video transmitters/senders, microwave ovens, wireless gaming console controllers & wireless broadband networks. All of these devices can contribute to line interference, which can cause the phone line to be dropped or experience a reduction in signal clarity/quality. Telecom recommended solution If you have broadband, the best solution to substantially reduce the chance of line interference is to have a splitter installed by a Telecom technician. To arrange for this, please either email broadband@xtra.co.nz or call 0800 CALL XTRA [22 55 98]. Most digital cordless home phones have the ability to operate on a unique radio spectrum and therefore can minimise interference by "hopping" over existing wireless signals, or operating on a different frequency. To check what spectrum your handset operates on, check the product labelling, packaging or supplier's website. The recommendation is to consider home phones that use DECT or 5.8 GHz technology. Phones that use DECT technology such as the Oricom P80 and Panasonic 1805 operate on a channel dedicated for voice calls. Some phones such as the Uniden 2315 also use "anti - collision" technology that sense traffic on the band and "hops" over it, reducing likelihood of phone line dropping or a reduction in signal clarity/quality. Phones such as the Uniden Elite operate on the 5.8 Ghz spectrum which is relatively unpopulated by other devices, and should give better performance. Phones that operate on the unregulated 2.4Ghz spectrum, may be operating alongside a number of devices at the same time, which can result in "collisions" between the different devices. The following home phones are recommended by Telecom for customers who will share a home phone on the same line as their broadband service and therefore would like a solution to minimise the potential for line interference: DECT home phones Oricom P80 and P80 + 1 [with additional handset] Panasonic 1805 Panasonic 1807 [with additional handset] Panasonic 1808 [with two additional handsets] Panasonic 1810 Panasonic 1850 Uniden 2315 and 2315 + 1 [with additional handset] Uniden DSS2415 5.8 Ghz technology home phones: Panasonic 5821 Uniden DSS7815 + 1 Uniden Elite Vtech 5825 Vtech 6821 The range of phones listed above are a summary of Telecom's home phones that are recommended for customers that share broadband on the same line as their home phone. This list of home phones can be added to, deleted and changed by Telecom without notice.

| 1264317 | 2012-03-11 09:22:00 | You don't need a filter for the modem/router unless it shares a jackpoint with a phone. The filter prevents you from hearing the router on the phone line more than from the phone interfering with the modem although it does also do this. When you have a splitter installed instead of using filters it leaves the modem connected directly to the line and only filters the phones. Cordless phones and may other devices transmit RF and wires are basically aerials so in some cases they can interfere, quite often it can be fixed by moving them further away from the modem and also from the wiring in the wall, signal strength drops off rapidly with distance. Any source of electrical interference, particularly pulsing digital type signals, can potentially interfere with broadband if it's too close or too strong. |

| 1264318 | 2012-03-11 19:21:00 | I have a cordless ph. Bu then I have filters too....yes it's possible, but I'd be checking the filters before I blamed the phone. | pctek (84) | ||
| 1264319 | 2012-03-12 06:34:00 | My microwave used to cut my wireless when used. I just went into the modem settings and chose different channels until issue resolved. | sam m (517) | ||
| 1264320 | 2012-03-12 21:39:00 | Almost all home broadband routers operate their wireless in 2.4GHz band. This band is the most (ab)used and is definitely subject to interference. You will get interference from TV Senders, Cordless Phones, Microwaves, etc. Cordless phones can be bought running on DECT band 1.8GHz or 5.4GHz, but you cannot do anything about microwaves or your neignbour's AV sender. Just live with it :) | tmrafi (5179) | ||
