On the contrary, with proper equipment availability, the band will be quite a benefit, but I suggest that we not underestimate the negatives and overestimate the positives.
I would call myself rural, but not desolate. ;-) There's 2400 pigs on this property, no less than 100k pigs within a 1.5 mile radius, approximately 1M pigs in the county. Providing adequate current\next generation speeds to a 100 home subdivision or town is just as much of a pain due to foliage for me as it is for anyone else. I'd much rather point a TV sector from an existing tower or two than construct an 80' tower to overcome foliage before I can use equipment in legacy bands. This method reduce the points of failure and permits more sophisticated support systems (power backup, backhaul, security, etc.) than building little towers everywhere I want to serve a few houses. It also allows me to reach into new markets before I can justify the cost of setting up a full tower using legacy bands. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "Ryan Spott" <[email protected]> Sent: Monday, April 05, 2010 1:26 PM To: "WISPA General List" <[email protected]> Subject: Re: [WISPA] WISPA TV Whitespaces Meeting with the FCC > Mike, > > I would suggest that you not use this band if it does not meet your needs. > I > tend to not use 5.8 in my area as 5.8 does not meet my needs. > > Your needs appear to be different from mine. > > ryan > > On Mon, Apr 5, 2010 at 11:24 AM, Mike Hammett > <[email protected]>wrote: > >> So we're regressing to a bunch of high powered omnis?
