5 GHz – RSGB respond to Ofcom

The RSGB has published its response to the Ofcom statement on increasing the amount of the 5 GHz band that can be used for WiFi. The Amateur Satellite Service has a Space-to-Earth allocation at 5830-5850 MHz.

Annex 6 of the Ofcom 5 GHz statement says regarding Fixed Satellite Service (FSS) operation in 5725-5850 MHz:

“…once it becomes clear that this band will become used for Wi-Fi worldwide it will become less attractive for new satellites.”

“In Table 2 below we show the impact that different regulatory regimes for Wi-Fi might have on the exceedance of the protection criteria of the most sensitive satellites in 5.8 GHz assuming a comprehensive Wi-Fi roll-out across Europe and Africa.”

“As discussed previously, the risk of interference is an aggregate of all Wi-Fi use and so will rise slowly over a number of years rather than appearing suddenly.”

“The UK cannot cause interference to 5.8 GHz satellites on its own but it is fairly likely that Europe and Africa will follow our lead. This is likely to be driven by the potential for 5.8 GHz to become a worldwide Wi-Fi band.”

Aeneas CubeSat to Deploy 2.4 GHz Dish Antenna

Built by students at the University of Southern California (USC) Aeneas is a 3U CubeSat planned to launch August 2, 2012 from the Vandenburg Air Force Base on an Atlas-5 rocket into a 880 x 450 km 60.4 degree inclination orbit.

It aims to prove the concept of WiFi based tag tracking from Low Earth Orbit using the first ever 0.5 meter dish deployed from a CubeSat.

Small 1 watt asset tags will be on the ground and a similar transceiver is in feed piece of the deployed dish in the CubeSat. The satellite will surface track the position of the tag.

It plans to use a 436.00 MHz AX25 1200 bps beacon every 10 secs and a spread spectrum two-way link elsewhere in the 70cm band.

The WIFI transmitter will transmit on 2425.0 MHz with 1 watt of output power.

CP5, Cinema, CXBN, CSSWE, Horus, Re, ORSES and Aerocube-3 are expected to be deployed from the same launch.

AMSAT-UK 80 Meter Net recording 8th April 2012

The AMSAT-UK net is held every Sunday morning at 10am local time on a nominal frequency of 3.780 MHz. Due to interference the net may move either side of that frequency so tune around. Newcomers are most welcome to call-in.

Latest AMSAT-UK 80 Meter Net recording- HERE Sunday 8th April 2012.

 

SDR-Radio Console

Simon Brown HB9DRV in Switzerland has made available  recordings of Sunday’s AMSAT-UK 80m net that he made using a remote receiver in Poole, Dorset. What is remarkable about this recording is that a 20 km long experimental 2.4 GHz WiFi link was used at the Dorset end.

You can listen to the remote radio of Paul M0EYT in Poole, Dorset as well as other remote receivers in the United Kingdom and around the world via the Web Servers (Free)  page at http://www.sdr-radio.com/
