Comments on DuraFon Range
With cordless phones, range is the important number. Most people seldom take a cordless handset
more than 20 feet from its base. 100 feet will take you far beyond most homes, and a football field is just 300 feet long... yet
lots of people are asking for phones that can go a couple of kilometres or more.
It's tough to find a cordless with that kind of CONSISTENT range. The EnGenius cordless phones have the longest range of any cordless
phone that can legally be used in the Canada, and their range can be 1 Km to 6 or 7 Km or even more, depending on conditions.
The advertised ranges are seldom equaled in the real world, and the same phone may behave very differently in two places, or even in the same
place on two different days.
Some general principles:
- Cordless phones are generally able to maintain an existing conversation at a greater distance than they are able to start a conversation, and can ring at greater distances than they permit talking.
- With EnGenius DuraFons, you may be able to use text messaging in places where you can't have a verbal conversation.
- When you move around while using an analog cordless phone, near the end of its range, you will probably hear a "fluttering" sh-sh-sh sound.
- Vegetation affects range. "Broadleaf" trees (hardwoods such as maple and oak) limit range more than "conifers" (evergreen softwoods such as pine and fir).
- Near the range limit of any cordless phone, slight movements and changes in position can make a big difference in performance.
If you put your head between the handset and the base, you may lose the signal, but if you turn to let the handset be in line-of-sight
with the base, it may work just fine.
- If you can get the base up high, you will probably get more range.
- Range over water is usually better than range over land.
- A "range-boosting" antenna designed for the DuraFon system will boost range significantly. Order the SN-ULTRA-AK10L or SN-ULTRA-AK20L with 10 or 20 Metre low loss cable. DO NOT use third-party antennas or mismatched cables.
- With all else being equal, phones that operate on higher frequencies are usually better able to punch through dense walls, than phones operating on lower frequencies. HOWEVER, all things are seldom equal, and transmitting power may be more important than frequency.
- DuraFon signals will penetrate most thin-shell metal buildings at reduced ranges (but not a jailhouse).
