antenna in comment and analysis
Peter Cochrane's Blog: The one-box generation
Comment TV detection is through the tell-tale emissions of the local oscillator, which can be easily detected by a sensitive receiver with a directional antenna. Written on JetBlue 0038 flying from JFK to Rochester NY, and dispatched via a free hotel wi-fi... [26 Mar 2008]
Peter Cochrane's Blog: Aerial bombardment
Comment Over the past 50 years antenna technology has blossomed beyond recognition with fixed and multi-frequency designs based on regular planar and fractal geometry patterns. The competition for antenna space on our laptops and mobile devices is getting... [07 Jan 2008]
Peter Cochrane's Blog: Don't mess with mobile users
Comment When I look at a mobile phone I see a fixed-line phone with the cord severed and an antenna glued to the top. Written in my home office just outside Woodbridge in the UK and dispatched via my home LAN and broadband connection [07 Sep 2007]
Peter Cochrane's Blog: How I boosted my mobile signal
Comment Because the system is passive it is also reciprocal and ensures the signal from mobile phones at ground level can find a direct path to the cellular antenna site. But I must point out that the detailed engineering is complex, and at worst people... [18 Jul 2007]
Peter Cochrane's Blog: My changing TV habits
Comment One antenna and one coaxial down lead did the trick. Written on BA6947 flying from Malaga to Gatwick Airport and dispatched to silicon.com via a free wi-fi service in London a day later IPTV is gradually taking over my viewing time as conventional... [30 Apr 2007]
Peter Cochrane's Blog: Wi-fi really is everywhere
Comment The biggest practical difficulty was counting the actual number of dwellings and the biggest error generator was the inefficiency of my laptop antenna. There was no special antenna, no extra amplification, nothing but a naked laptop operating below... [10 Jan 2007]
Peter Cochrane's Blog: The search for spectrum
Comment However, every time I look at the spectrum using an analyser and antenna I find a desert, just a few signals and a lot of random noise. Written at Chatham House, London. Pics compiled on the road between Zurich and Southampton. [10 Oct 2005]
RFID: It's no supply chain saviour - not yet anyway
Comment Passive RFID tags, which are the most common kind at present, consist of a tiny memory circuit and antenna that can be printed onto a label. For retailers, stock control is a challenging task made even harder by the need to extract intelligent... [08 Sep 2004]
The Bloor Perspective: Wi-Finding, dirty money and techs in the City
Comment People rarely walk down the street with their laptop switched on, antenna twitching searching for a wireless network. If we are to believe the hype, wireless hotspots will be everywhere. They're not all here today but promised in the near future. [09 Jan 2004]
Powerline coming of age
Comment The measured antenna efficiency from real power cables is about 30dB less than for a tuned dipole antenna making them anything but effective radiators/receivers For a number of years we have been promised data services delivered via power line... [05 Sep 2003]
Peter Cochrane's Uncommon Sense: DIY v DIFM networks
Comment This was the birth of the Community Antenna TV (CATV), which ultimately became CAble TV in the 1970s and 1980s. Most types of successful networks have seen an element of end user innovation, says Peter Cochrane. [26 Jun 2003]
Peter Cochrane's Uncommon Sense: Intelligent machines
Comment There are also new antenna technologies that are ~x4 more efficient, displays that require no back lighting and data storage devices that are ~x100 denser than today. Peter Cochrane sees advances in most areas of technology. [17 Apr 2003]
Peter Cochrane's Uncommon Sense: Your communications - compromised
Comment For radio, all someone basically needs is an antenna to suck information right out of the ether. Is Wi-Fi much more insecure than wireline networking? How many security clangers do you drop while on your mobile? [18 Sep 2002]
3GSM Review: Ovum on vendors' flight from hype
Comment The helpful Lucent engineer advised me to take a few steps back because: "We've discovered that with W-CDMA there is a blind spot immediately below the antenna. Major infrastructure vendors are making serious efforts to reign in the hype that has... [01 Mar 2002]
