Wired and Wireless
Blue is not just the pristine air, but where streams of data dance into the sky...
Western Nevada County’s in-place and expanding telecommunications infrastructure is providing local businesses global access to existing and emerging markets. In addition to multiple Internet service providers, businesses have access to a wide range of high speed data services, including:
• Fiber optics: Telephone and cable
• Frame relay
• ISDN and faster DSL by multiple providers
• Dedicated T-1 and fractional T-1 services by multiple providers
• Cable High Speed Internet
• Fixed Wireless Broadband
Whether it's a T1 line extending itself to rural home-based businesses that offer broadband via WiFi to other entrepreneurs in the neighborhood or the installation of a cell tower that cleverly blends into the forested geography - Nevada County is wired. The downtown districts are covered by wireless Internet access.
Internet access in our geographically diverse area of hills and trees and low population density can be both a technical and a business challenge. Most anyone can utilize the slower dial-up connections, but DSL and cable may only be offered in more densely populated neighborhoods and downtown areas of Grass Valley and Nevada City. If you are beyond DSL and cable, you may want to consider Satellite service, or if you have a collection of neighbors you could consider creating and sharing a “neighborhood network”. Often, we hear of new residents wanting “faster than DSL” speeds they were accustomed to in metropolitan areas; if you can not get DSL in your neighborhood, your next best option is probably a T1 – but remember the local loop charge in a rural area will often be the same or higher than the cost of the T1 charge. Larger business will most likely have a network administrator who will be familiar with an array of enterprise solutions.
Nevada County has been an innovator in the past. Gold was the allure, and early-adopted telephones piped critical information to the miners needing an advance warning system. Today, water and telecommunications infrastructure is the gold of Nevada County. Like the telephone lines in the past, our digital pipes keep us informed; as well as help cultivate, attract, and retain our innovators.
1 IDSL - ISDN Digital Subscriber Line, a way of providing
DSL over existing ISDN lines. The transfer rates for IDSL is about the
same as ISDN and only carries data, but the connection is always-on and
has a flat billing rate.
2 Must have clear view to satellite and snow or heavy rain usually affect
service.
3 DSL - digital subscriber line.
ADSL - Asymetrical DSL. It can
download faster than upload. Less expensive. Usually in residential.
SDSL - Symetrical DSL. Same bandwidth in both directions. More common
for business use.
4 Everyone on cable shares bandwidth. So if a lot
of people in your neighborhood are using the service performance can be
much slower.
5 T1 prices have dropped, but the local loop in rural areas can be expensive
- nearly doubling the price of similar service in a metropolitain area.
6 Wireless availability is usaually line-of-sight, but with right antennas,
boosters, and repeaters service is available even through trees in all
but the heaviest rain and snow.

Cellular Data: Check out the article, "Using a High-Speed Wireless Card" by Brian Jepson, in the premiere issue of of Make: technology on your time (Vol. 1, Feb. 2005, O'Reilly Media). The article gives an overview of various cellular data services, costs, performance, the new 1xEV-DO service from Verizon (which tested an average of 370kbps!), and the use of external antennas.

IDSL: ISDN Digital Subscriber Line, a way of providing
DSL over existing ISDN lines. ISDN has two channels and may
have both voice and data in the circuit, has call setup delays and is
usually billed with a per minute fee. Providing DSL on ISDN gives you
transfer speeds of 144kbps, about the same as ISDN, but it only carries
data. The connection is always-on and has a flat billing rate. If you
live beyond DSL, IDSL may be a good option to consider compared to analog
modems though it probably will be priced higher than DSL. Another consideration
is VPN (Virtual Private Network). If you need VPN to securely connect
to a company network, Satellite (at this time) will not support VPN while
IDSL will. So, if you need VPN, you can't get DSL, and don't have
a "neighborhood network", IDSL may be your best choice even over Satellite.
Wi-Fi: Usually a great solution for wireless HotSpot networks in businesses, or homes. People have accomplished line-of-sight Wi-Fi over distances of 20 miles with proper equipment, and created Wi-Fi networks in neighborhoods in dense forests that operate well in all but the hardest of rain storms. Hotspots coverage usually depends on effective antenna orientation and signal strength.
WiMAX: it's coming, but has not arrived in Nevada County yet. Keep in mind, it is probably not a direct hotspot replacement. WiMAX is more intended as a tower-to-rooftop solution - getting broadband to "the last mile", then the customer uses a wired, or wireless, LAN to distirbute the bandwidth. Eventually there may be WiMAX capable cards for your laptop, but not currently.
