Small Towns Now Have BIG Internet Small Towns Now Have BIG Internet ServiceService
Midwest Wireless is deploying broadband Internet service in several rural communities with the help of a grant from the Minnesota Department of Trade and Economic Development (DTED).
Customer Premise Equipment /2.4 GHz FHSS
Orthogonal Frequency Division Multiplexing 5.8 GHz
Technology enables the link between the Access Unit (the tower) and Customer Premise Equipment of speeds 20 times faster then the FHSS 2.4 GHz existing technology.
CPE to AU
The Numbers
• Began in Spring of 2001– 142 customers our first year
• Currently 168 Sites– Grain Elevators– Water Towers– Cell Site Co-location
• Serving members of 359 Communities
• ~12,000 Customers and Growing
