I don't want to be pessimestic but it is an already lost crusade...See what's ARRL was planning to
do in 2001!!!
ARRL Asks FCC to Investigate Long-Range Cordless Telephone Sales
NEWINGTON, CT, May 30, 2001--The ARRL has asked the FCC to investigate and "take appropriate
action" against several companies it alleges have been marketing so-called "long-range cordless
telephones" via the Internet. The ARRL took the action in the wake of numerous complaints from the
amateur community about sales of the devices, some of which operate on VHF and UHF frequencies
allocated to the Amateur Service.
"Because these devices operate on Amateur bands and are capable of causing severe interference to
ongoing Amateur communications, and because these devices likely will not meet MPE [Maximum
Permissible Exposure] levels for RF exposure, the matter is considered urgent," said the May 29
letter from ARRL General Counsel Chris Imlay, W3KD.
The letter was addressed to FCC Enforcement Bureau Chief David Solomon as well as to Raymond
LaForge of the FCC's Office of Engineering and Technology's Equipment Authorization Division and to
FCC Special Counsel for Amateur Radio Enforcement Riley Hollingsworth.
"ARRL has not been able to locate any FCC certification for these devices and, based on the
advertised frequency bands and ranges, it is believed that none of these devices could be
certificated, or legally marketed or sold, under FCC rules," Imlay wrote.
Imlay said the ARRL also is looking into the marketing of products such as 434-MHz video
surveillance equipment and other "apparently non-certificated devices" that use amateur frequencies
but are being marketed in the US to non-amateurs.
ARRL Lab Supervisor Ed Hare, W1RFI, said he's received several reports concerning long-range
cordless telephone devices advertised for sale on the Internet and via auction sites such as eBay.
"One of the reports, from Bill Erhardt, K7MT, involved actual harmful interference to amateur
communications," Hare said. Erhardt tracked the telephone to a neighbor's home. The neighbor told
him he'd bought it on eBay.
Hare said he was glad to see the issue put into the FCC's hands. "All intentional transmitting
devices that are marketed in the US must be FCC certificated, as described in the FCC rules," he
said. "At the advertised power levels and frequencies, I do not believe that these phones could
have been certificated."

The ARRL was able to obtain one of the long-distance cordless telephones for testing. The device,
manufactured in China, bears no FCC identification number or label. The ARRL technical staff
determined that the device--an Optima 8810--operates at an output power of greater than 3 W near
147 MHz. Other such phones are advertised as having ranges of up to 100 km operating at power
levels of up to 35 W on VHF and UHF. Some models use frequencies in the amateur 2-meter and 1.25-
meter bands.
The ARRL offered to send the telephone device "and as much information as it can obtain about the
eBay seller" to the FCC. In his letter Imlay noted that the vendor has since disappeared from the
auction site.
One of the companies selling the long-range cordless telephones had originally indicated that one
such device operated on 147 and 230 MHz. Apparently after it heard complaints from amateurs, the
company altered its Web site listing to indicate that the phone operated at 249 and 375 MHz. The
ARRL attached to its letter a copy of the Web site of another seller that showed the same telephone
as operating on 150 and 230 MHz. The League said some of the companies also may be selling similar
wireless products that may operate on amateur or restricted bands.
Hare said some long-range devices are legally certificated to operate on the 900 MHz or 2450 MHz
Part 15 bands. "These legal devices are only an issue if they cause actual harmful interference to
the Amateur Service," he said.
Hare requested reports of unlicensed devices causing actual harmful interference to Amateur Radio
operation. Reports may be sent to rfi@arrl.org.
Even more FCC in an exchange of letter ask the parties to setlle the problem by themselves...

RE: Radio Frequency Interference
Dear Mr. Brunetti:
The Federal Communications Commission notified you by letter on December 1, 2003, that it has
received complaints of harmful radio interference possibly caused by equipment operated by Xcel
Energy. This interference has been reported by an operator in the Amateur Radio Service. The
complainant is:
(name and address deleted)
Wellington, CO 80549
In the letter you were advised that this problem, if unresolved, could be a violation of Commission
rules and could result in a monetary forfeiture. For this reason, we encouraged the parties
involved to voluntarily resolve this matter without Commission intervention.
You were further advised to inform the complainant within 60 days of what steps would be taken to
correct the reported interference problem. In addition, if unable to resolve this matter by
February 1, 2004, you were advised to inform this office about the nature of the problem, the steps
being taken to resolve it and the estimated time in which those steps could be accomplished.
Although you responded to Mr. ---------- within the specified time period, the harmful interference
he reported to this office still remains unresolved.
In order to avoid possible enforcement action, please advise this office within 30 days of
receiving this letter of what action you have taken, or intend to take, in order to identify and
correct the source of these radio emissions if they are being caused by your equipment.
If you have any questions about this matter, please contact me at 717-338-2502.

I doubt FCC can extend his jurisdiction into China mainland
To close this post have a look at this link and just remember that in some countries where cell
phone are unavailable theses phone are the only one alternative.
http://www.globalsources.com/manufacturers/Long-Range-Cordless-Telephone.html
One one my client who is working actually in China mainland just told me there is Wall Mart size
store where the entire floor is devoted only to cell phone and all kind of cordless phones. As per
his own words "I never see that and the store is always crowded as much as the streets are by
peoples."
Just wait and watch when the news will reach the young teckies folks...Wow 30 miles free phone! We
better be prepared with our DF stuff!
