First-Mile
internet access
Increasing
internet usage, video on demand and telecommuting are driving demand for faster
first-mile access while exerting downward pressure on pricing. Today much
of the US population has access to ADSL/VDSL from traditional telephone
carriers and DOCSIS from Cable TV providers. However both are falling
behind the gold standard of FTTP (fiber to the premise) capable of
delivering virtually unlimited speed. Cellular carriers are also entering
the world of high speed internet access.
In
the US the FCC broadband definition, set in 2015, was 25 Mbps download
and 3 Mbps upload. In 2024 the FCC increased it to 100 Mbps download and
20 Mbps upload.
This
paper discusses the various technologies used to connect customers to
their ISP (internet service provider).

Hands-on experience installing a small
LAN. Paper covers a broad range of
topics: internet connection sharing, Ethernet and WiFi, VoIP landline
telephone, configuring network PCs and implementing a poor-man's home
server. Being a small business I discuss the advantage of registering an
internet domain name and using a hosting service for web site and email.

50/50 Mbps PON ISP fiber has been working
great for both internet and VoIP landline phone. This is the 25th
anniversary of our internet connected home network. It began with V.34
(33.6 kbps) dialup and a few 10 Mbps Ethernet drops. Now it has a fiber
PON internet connection, 20+ Gig Ethernet drops and dual-band WiFi.

Changes this edition: Consolidated
Communications under Fidium branding is aggressively deploying PON
(passive optical network) symmetric internet access in New Hampshire. We
were finally able to upgrade from 6 Mbps DSL to 50/50 Mbps PON and
switched our landline to Consolidated VoIP (voice over internet protocol).

Living

Changes this edition: with Win 7 at end of
support I upgraded/replaced our suite of PCs and laptops to Win 10. We
also had to change the way we stream internet content for our TV, now
using a Roku Express media player. I built a DC UPS to keep our network alive
during power outages when our backup generator is not running.

Dialup
modem access adapter - device prevents interference when
telephone and dialup modem share a phone line. When modem attempts to
dial out the adapter searches for an idle phone line over a maximum of
two POTS (plain old telephone service) lines. It disconnects phone before
connecting the modem. This prevents dumping a data connection if phone is
picked during a session and conversely the modem barging into an existing
phone conversation. If both lines are busy modem has to retry later.

Dialup
modem impairments – V.90 & V.92 modems are the pinnacle of
dialup networking but are very demanding of the PSTN (public switched

common impairments that degrade speed.

Postal
mailbox alert - our house is about 600 feet (190 meters) from the
road and the mailbox is located on the far side of the road. Now that we
have fiber internet I repurposed the retired outdoor copper telephone
cable to link a low cost key fob on/off RF transmitter at the mailbox to
a receiver at the end of the driveway. I used the same WebControl PLC as
other projects. When mail is
delivered the system illuminates an LED in the kitchen and sends a text
message to my cell phone.

Bucket
seat tire swing - growing up there was a tire swing at my
grandparents’ house. This was more than just an old tire hanging from a
rope. About 2/3rds of the tread was cut away and the tire turned inside
out resulting in a bucket seat. I had many joyful memories so wanted to
make one for our granddaughter.

External
battery DC output UPS - I wanted to keep our LAN operational
during power outages when our generator is not running. The UPS replaced
device wall warts and powers network devices directly with DC. Rather
than including a SLA (sealed lead acid) battery I used an automotive jump
pack as the battery. This is the best of both worlds: the UPS gets a free
battery and the UPS keeps the jump pack topped up so it is ready for use.

Second
generation wood heat controller – the greenhouse controller ended
up being so successful it motivated me to redesign the original wood
stove controller using the same WebControl PLC. Device monitors flue

to increase safety and efficiency. Note: this design has been superseded
by the 2nd generation

Future
of home networking - a few decades ago computer networks were the
province of large companies with well-funded IT departments. Internet
access was little known outside a small cadre of network professionals.
Advances in wired and wireless network technologies have made small
internet connected residential LANs the norm rather than the exception
today. This paper extrapolates from the last decade to predict how this
critical market will evolve.

IP
vs RF television - high speed internet access creates an alternative
television delivery method. Where adequate bandwidth exists IPTV is
capable of a much richer suite of services than either Cable or
over-the-air TV. IPTV leverages internet infrastructure eliminating the
need for a dedicated TV distribution network.

Commercial
peer-to-peer distribution - there is much hand ringing by the
music and movie industry that internet P2P (peer-to-peer) file sharing
will be the death of artistic expression rather than an exciting
opportunity to lower distribution cost. This paper proposes a P2P
mechanism for commercial content distribution that compensates artists,
provides incentives for customers to play by the rules while dramatically
reducing distribution cost.

Do
third party ISPs facilitate broadband competition? - one of the
more controversial aspects of broadband is the power exercised by
first-mile network owners over third party ISPs and the regulatory
requirements to share these facilities. This paper argues for a different
approach. First-mile networks should provide common carriage - transparent
IP delivery. This allows application developers and ISPs to operate at
the network edge independent of physical connection.

ISP
business practice impact on home networks - broadband ISPs are
adopting restrictive measures that violate the cherished notion of
transparent data delivery. This business strategy has a profound effect
on residential networks. This paper was written in 2002 to provide

Association) VHN (Versatile Home Network) and ISO (International
Standards Organization) RG (Residential Gateway) standard activity.
