Where to start?
The fist thing you need to ask is “How many customers are likely in the next 18 to 24 months?”
A few or many???

WISP Types
We basically find three different types of WISPs. Small Rural (300 customers or less) Large Urban (more than 300 customers) Campus (many customers but confined area)

Small/Rural• DSSS
– Maximum of three WPOPs
• Strengths – Cheap– Long range– Multiple equipment choices– Fast– Able to be programmed away from known interference
• Weaknesses– Everyone can buy the radios everywhere– Cheap– Long range– Susceptible to narrow band interference
November 26 2001 Marlon K. Schafer, CTO--KMS Wireless (509) 982-2181
Large/Urban
• FHSS– Maximum of 12 WPOPs
• Strengths– Scalable– Dynamically avoids interference– Secure– Robust– Obscure
• Weaknesses– More proprietary– Not as fast as DSSS– Expensive

Campus
• FHSS/DSSS– Coverage zones must be tightly controled
• Strengths– Scalable– Dynamically avoids interference– Secure– Robust– Obscure
• Weaknesses– More proprietary– Not as fast as DSSS– Expensive

Costs
There are several levels of quality and security for this equipment. As would be expected the better the gear the more the costs.

Rural WISP WPOP Estimate
This is for a middle of the road DSSS system:
• Access Point: $600
• Amplifier: $500
• Antenna: $200
• Cables: $150
• Labor: $500
• CPE: $400+

Urban WISP WPOP Estimate
This is for an upper level FHSS system:
• Access Point: $2500
• Antenna: $600
• Cables: $100
• Labor: $500
• CPE: $950+Note: In most populated markets there will need to be at least two of
these, 4 to 6 per broadcast site is normally easier to deal with.

Campus or Industrial Zone Estimate
Access Point: $600 to $3000+
Antenna: $100+
Amplifier: $500??? (may not need/want)
Cables: $100+
Labor: $500+++
CPE: $100+

Conclusion
There is a real and tangible need for broadband services today and it’s increasing daily.
You can save money or make money be delivering broadband access to your employees or customers.
Just make sure you don’t waste your money by putting in a system that won’t work or costs more than people can/will pay for.
