[Hidden-tech] Ashfield man pitches high-speed Wi-Fi plan

Here are a few more points of interest for a radio based internet service:
1. WiFi is limited, by FCC law, as to power level. One watt maximum, except
when directional antennas are used. Up to 4 Watts with highly directional
antennas.
A typical WiFi box runs either 0.1 or 0.2 watts.
2. All other things equal, it takes 4 times the power to double range of
any radio signal. This is known as the “square law,” and is a minimum value
that is only valid for communications in space.. Most often it takes more
than 4 times the power to double range because of additional absorbition
and reflections at a further distance.
3. A dish antenna emits a pencil beam. The larger the dish, the smaller the
beam. This is where antenna gain comes from: more signal into one direction
at the expense of all other directions.
4. Nothing is gained from connecting many antennas in parallel. The energy
is divided among each of the antennas, almost. The “almost” part refers to
the amount of signal lost in the inter-connection structure.
5. Flat plate antennas have less gain that dish antennas. The gain of an
antenna is primarly given by its size. A larger antenna has a smaller beam,
which results in more gain.
With antennas, there ain’t no free lunch!
6. Disagree with me if you wish, but the significant part of signal loss
through & past trees is due to reflection from leaves, dry or wet, not
energy absorbed by the leaves. Yes I have observed this at frequencies just
above the WiFi band.
---
A few years ago I thought of placing a similar system in Ashfield to help
some of my family and have a business. A bit more thought convinced me
that, as a minimum, I needed a tower, or two, or three on the highest
hill(s), some power at a frequency that I would need a license for,
infrastructure, and lawyers.
Sounds like your friendly cell phone company, doesn’t it.

This is similar to what AccessPlus / Country Roads is offering. Some
*important* things to note:
This won't be anything close to 'Universal Service'. Western Mass has the
wrong sort of terrian to provide anything close to 'Universal Service' via
wireless. High speed wireless Internet means VHF (Very High Frequency)
radios, which is line-of-sight and which is readily absorbed by moist (wet)
leaves and snow covered branches. Forested hills (and valleys) will leave
many people unable to get service, *even* when they are close to the access
point -- the 700mhz and 900mhz access point techology has a range of about
1/2
mile. And yes, rooftop repeaters are possible up to a point (each repeater
adds some latency). *Some* towns have just the 'right' sort of topology
for
this sort of service to work well (Warwick is one example), but many towns
don't.
Wireless is also bandwidth limited and is a *shared* bandwidth resource.
The
upper bandwidth (for typical residental service) is going be be *less* than
DSL and because it is a shared resource the more people using an access
point,
the less bandwidth will be available for any one subscriber.
Wireless 'solutions' like this are at best a sort term stop gap and in the
long term a fiber to the home solution is the really only long-term,
'future
proof' option.
