Updated 1st Jan 2006 EUROPE SATELLITE CAPACITY NOW FOR SALE WITH EFFECT FROM 1 JAN 2006.
I have been helping Windmill Digital Broadcasting with the distribution of a private sound audio distribution service (music and advertisements) in the UK and Ireland (Europe) area, using the Eutelsat W2 satellite coverage beam from the 16 deg E orbit position. I turned the service off on 31st Dec 2005 at 10pm, after the all Homebase stores had shut.
The satellite sound audio distribution receivers may be located anywhere within the inner 50 dBW contour and use approx 89cm diameter dishes. There was at least 5dB rain margin at every site and the service is 'rock solid'. The network operated as a closed, private system with controlled Wegener DR95 receivers at every site, connected to audio amplifiers and loudspeakers. Two music audio channels are on the same carrier but are used for two different groups of shops, UK and Ireland, each group receiving a mono music channel interspersed with their own advertisements.
This was done using SCPC (Single Channel per Carrier) satellite technique which provides dedicated transmission.
Service was available anywhere in this Europe coverage beam. As used
for one-way stereo broadcast music - see red map below for the new
replacement service coverage area.
FOR SALE: I am looking for a new customer who needs satellite bandwidth in the coverage area below. The hub is in the UK and we have a music / adverts play out server with all legal, royalty paid for, music selection.
We have about 90 spare Wegener Dr-95 receivers for new sites, each of which would need just a satellite TV dish and LNB.
If you want a one-way music/advert operation I will get my friendly music/advert person to help you. All you need to do is send us the text of the adverts you want. We record the adverts (male, female, Irish etc) and put all the music together and can respond quickly to pull an advert from the schedule if you sell out.

Alternative uses using CDM570L modems:
IP broadcast: The bandwidth could be used for an IP data broadcast service to a number of remote radio station sites with feedback telemetry about equipment status etc.
The coverage map on the right will now be used as we have capacity available on that satellite for two way use. For example: 512 kbit/s download bit rate and 2.4 kbit/s uplink bit rate from each site.
CCTV monitoring: A broadcast 10 kbit/s carrier would go out to all sites to control camera angles, resolution, zoom etc. In the return direction all sites would transmit slowly all of the time and if requested from the hub a few selected sites could be commanded to transmit higher resolution at higher bit rates. So perhaps 10kbit/s outbound, plus 10 x 64 kbit/s inbounds, plus 512k inbound extra capacity available for any remote to transmit at higher speed on command.
Regular internet access: Broadcast 15n kbit/s outbound and 3m kbit/s inbound per site. Where n = total number of PCs is the system and m is the number of PCs at that site.
Your VSAT terminals may be anywhere on the coverage map. One-way or two-way bit rates are available as required 2.4kbit/s - 5 Mbit/s. Dish size 89cm + 3 watt TRIA (50 dBW contour), larger dishes needed on outer contours 1.2m on 47 dBW, 1.8m on 45 dB contour for regular QPSK transmission.
Approx prices: $8500 per site plus $700 per month for 100 kbit/s. 2/3 or 1/2 lower prices if you use larger dishes and 8-PSK or 16-QAM modulation.
