Philadelphia is considering a wireless Internet system that would
blanket the entire city via hundreds of small transmitters.

Would this interfere with ham radio?

Sounds like a possible nice alternative to BPL :-)

Unless we have bad harmonics way up on microwaves, it should not. Looks like
NYC already has WiFi distribution, you can see WiFi Hotspot antennas on the top
of the public phone booths.

===========================

It's not the UHF frequency of the very local mini transmitters which cause
the interference.

It is the broadband signals which come in via the phone wires between
computer and the local telephone exchange. They mostly affect the 160 and 80
meter bands.

This would cause US to interfere with the computers.


"Each would be capable of communicating with the wireless networking cards
that now come standard with many computers. "

Isn't this all 802.11 which is up at 2+ GHz and above?

Steve N, K,9;d, c. i My email has no u's.

Firstly, why do you think it would interfere?

Damn communists... ;-)

Aren't such "wireless" systems typically on the unlicensed 2.45GHz
'microwave oven' band?

In any case, such a system shouldn't cause any significant out-of-band
interference.

If done like Chaska MN, it would be using 1 watt 802.11G transmitters
with 6 dBd vertically polarized antennas. The system is a mesh network
fed from relatively few points. These systems transmit only when
traffic needs to be passed. The density varies from about 8 to 20
transmitters per square mile from what I've been told by the city.

I have heard of no complaints from weak signal 1296 users in the area,
and I am a member of the local VHF/UHF/uwave club.

Oops, I meant 2.4 gigs.

If the French had despensed their responsibilities in French Indo-China
properly, there would have been no danger of an iterative collapse of
dominoes to communism in the region. The U.S. would not have offered
help to a corrupt anticommunist regime which squandered the help it
received.

The tragedy reminds me of the old story of the knight who hurries home
to report to his king that he has slain or subdued all of the king`s
enemies in a neighboring kingdom. The king replies that he has no
enemies in the neighboring kingdom. The knight corrects the king by
saying, "You do now sir!"
