Range depends upon your local environment: typically 12 floors in building, , sq. You can connect one or even two external antennas for additional range and coverage area. Straight-line "open field" range has been tested at over five miles. Typical range is a mile or two.

In order to access the RSSI tool in the handset please follow the following steps. First press the softkey under menu. After you go through the above steps you will see the following screen. DuraFon 1x BU values are Pro BU values are Press the number 1 on the keypad to access the BER menu. Note: If you do lose the link between handset and base, exit the menu, and enter back in it again.
The frequency deviation should not exceed Hz at a distance of less than 20 ft from the BU. If you experience a frequency deviation of more than Hz from the BU at a distance of less than 20 ft.
It is important that if any changes are made during the RSSI testing, other than the HS distance to the BU, such as a different antenna on the HS or BU relocation, that the changes be made one parameter at a time, and after each parameter change the RSSI test is run again to see the difference that one change at a time causes. Note: Using the short antenna on the HS may cause up to a -5 to -8dB difference compared to the long antenna in real world deployments.
There are three ways to improve DuraFon handset-to-handset range, in order of increasing cost: Use of the larger antenna on the The long antenna clears the side of the head, leading to an effective five to seven dB gain on each side. This long antenna makes the antenna on the HS now more susceptible to breakage due to the amount of protrusion the long antenna has compared to the short antenna. This solution is now being deprecated in favor of option 3. This is the preferred solution we are recommending going forward i.
Here is an example of three concurrent SIP calls with one analog call. The analog line can be used as a backup if connectivity is lost to the SIP server. The analog line can also be connected to a door call system, an analog PA paging system, a call box, an entry controller and many more applications.
Our phone systems also use the MHz frequency as well, so before deploying our phone systems in an environment where nurse call systems are already in place, or planning on being deployed, it is highly recommend that a MHz wireless sight survey is preformed using a MHz spectrum analyzer to determine if the location can accommodate both systems running without causing a noticeable detriment on either systems operation.
If TAP is required after a phone system has been deployed, then please contact one of our support representatives so the HS can be shipped to us for a firmware upgrade to support TAP, and if your BU has a DB-9 serial connector the BU will also need to be shipped back to us so we can perform a firmware upgrade on the BU as well.
Please note that this is not dual band concurrent, it is dual band switchable, so you can only communicate with either the DuraFon Pro BU or another UHF radio, not both at the same time. Below is a list of pre-defined channels and their respected mapped frequencies.
