WiB - ultra wideband efficient UHF broadcast

[[Teracom]], inspired by earlier research {{cite journal|author1=Yiyan Wu|author2=Bo Rong|author3=Khalil Salehian|author4=Gilles Gagnon|title=Cloud Transmission: A New Spectrum-Reuse Friendly Digital Terrestrial Broadcasting Transmission System|journal=IEEE Transactions on Broadcasting|date=21 June 2012|volume=58, Issue: 3|pages=329 - 337|doi=10.1109/TBC.2012.2199598|url= http://ieeexplore.ieee.org/document/6222350/?arnumber=6222350 |accessdate=25 June 2017|publisher=IEEE|issn=1557-9611}} , introduced a new system concept dubbed "WiB", that aims to improve [[frequency reuse]] in the [[Ultra high frequency|UHF band]] while at the same time enable savings in both operating power and capital expenditures costs. {{cite conference|author1=E.

Vista DHCP bug - WiFi connect failed

Vista refuses to connect to certain wifi routers. I worked around the wide spread issue by forcing a static IP to the client. Is this the proper solution? http://support.microsoft.com/kb/928233 I guess we will never know. Thankfully the now vintage laptop is well supported by Ubuntu 14.04 LTS, so the problem is solved for good.

Receiving FM radio without an antenna

I've started experimenting with my TV & radio tuners. One of them gets perfect reception on 15 of the 17 nearby FM radio stations in the area. It gives acceptable quality on the remaining two talk radios. It's an Asus 3in1, supporting hybrid PAL/DVB-T/DVB-S/FM. My UHF TV aerial is just a bare wire of proper length at the end of an extension cable. FM reception gets a bit weaker on some channels after disconnecting it. I've tried to disconnect every cable except the display, power and keyboard to no effect. A proposed explanation is coupling through the power lines and/or improper grounding. Three of the broadcasts are high power regional transmitters with nearby origin. The rest are local ones with reduced power that also transmit from the surrounding hills. I made a script that uses fmtools to scan and tune in channels. It also coordinates digital audio capture and playback from the card's ADC. I've also experimented with gnomeradio. Unfortunately, I ha...

DVB-T XMLTV EPG grabber complete

It runs on over the air broadcast, so you won't see any more grabber failures because of a website that decided to change their design (deliberately). bkil-open: tv/grab-dvb-epg.sh
