WI-FI: Wireless Fidelity
Hi-Speed, wireless communications, limited
distance
Three Standards;



802.11b: 11mbps
802.11a: 54mpbs – incompatible with 802.11b
802.11g: 54mpbs – backwards compatible
w/802.11b
Range – 50’ thru obstructions, 100’ clear view
WI-FI: Equipment
802.11b/g Access Point ($150).


WI-FI hub connected to network.
Can also be used to retrofit desktop PC’s.
802.11b/g Gateway ($150).

WI-FI hub, plus Internet router/firewall/gateway.
802.11b/g PCMCIA (Cardbus) add-in to
laptop ($99)
802.11b/g Mini-PCI laptop built-in WI-FI .
WI-FI: Security
Service Area ID (SSID) Broadcast:

Turn off SSID broadcast so snoopers can’t discover WI-FI
name.
Encryption


40/64-bit, 128-bit (WEP), 256-bit (WPA)
Acts like a magic decoder ring to scramble communications
as its transmitted, descramble when received.
MAC Authorization

Explicitly authorize only certain WI-FI devices to use your
network.
WI-FI: Applications
(telnet)
Communications is carried via WI-FI connected to
Local Area Network (LAN) or Internet



Uses low-cost (free?), WI-FI connection to Internet.
No long distance toll charges or expensive leased line.
Ideal for a telecommuter or mobile sales force.
WI-FI: Applications
Virtual Public Network (VPN)
Encrypted communications between devices.
 Both ends use a common encryption key, also known as a "private
key".
 VPN router devices uses private key to encrypt all packets.
Secure/reliable, even on public networks.
Encrypted “tunnel” through the Internet.
Local Area Networks (LANs) connected as a Wide Area Network (WAN)
Enables secure exchange of all types of networked based services:
 Terminal Emulator/TELNET program used to connect to
host/server.
 File and Print Sharing, Network File System(NFS).
 All services typically associated with a Local Area Network (LAN)
Security Issues Dramatically Reduced
VPN TUNNELING Wide Area Network
Encrypted “tunnel” through the Internet.
Local Area Networks (LANs) connected as a Wide
Area Network (WAN)
Enables secure exchange of all types of networked
based services:



RITA - Terminal Emulator/TELNET program used to connect
to host/server.
File and Print Sharing, Network File System(NFS), I: drive.
All services typically associated with a Local Area Network
(LAN)
Security Issues Dramatically Reduced
Other Internet Services
Internet access means much more than just
communication route.


Web Browsing: Enable PC users to visit manufacturers web
sites for product information and the ability to place and
check on the status of orders.
Email: Perhaps the most ubiquitous tool for the 20th century.



Instant Messaging:



Replaces phone calls to branches (and long distance tolls).
Send email to multiple parties at the same time, reduces
duplicate efforts.
Newest, instant, non-verbal, communications.
Rivals telephone in ability to interrupt.
VoIP: Voice-Over-Internet-Protocol.

VoIP phones allows connect telephone handsets in the branch
to the main phone system in your central office.
Types Of Connections
"IP" communications utilize a variety of types of
Internet connections.



T-1 circuits provide the highest bandwidth available;
1500Kbaud. Highest price point too; $900-$1,500/month.
DSL (Digital Subscriber Line)/Cable modems offer fast
speeds; 128Kbaud-768Kbaud. Less expensive; $30$120/month.
Simple 56Kbaud dial-up circuits; $15-$25/month plus cost of
phone line. 56Kbaud dial-up lines should be used only as a last resort for
small branches.
Full-time access needed at main office.
“Static IP address” required.
CASE STUDY
Moderate sized, independent welding
supply/industrial gas distributor in
Southeast.
 Four remote branches, 150mile radius, 2
crossed state lines (inter-lata).
 Traditional 4-wire, 9600 baud, analog,
leased lines = $1,200/mo for 3 branches.
 Estimated cost of 4th branch prohibitive at
$800/mo. Total = $2,000/mo.

CASE STUDY







56K point-to-point digital circuits rejected. No
savings.
56K Frame Relay rejected. Small savings, large
hardware investment.
DSL implemented at main office ($80/mo) and 2
branches ($60/mo) = $200/mo.
Cable modem at 2 branches = $75/mo.
Total Internet Connectivity = $350/mo.
Estimated savings = $1,650/mo.
15 month Return On Investment
PITFALLS

DSL & CableTV ramp-up problems.







Installation schedules typically aren’t met.
DO NOT OPT FOR SELF-INSTALLATION.
DO NOT DISCONNECT LEGACY EQUIPMENT (leased
lines) UNTIL NEW SERVICE IS FULLY FUNCTIONAL.
Do not sign long-term contracts.
PC’s require more software maintenance &
configuration.
Employee training considerations.
Internet acceptable use policy needed.
