A train ride completly underground from with the Ooedo Line from Shinjuku-nishiguchi to Ueno-Okachimachi. You can hear the wifi network (steady monotonous rhythm) provided by the owner of the line at each station (there must be 9 stations). The first 4min detektor was waiting for the train. 2nd train station is coming closer at 05:18, 3rd 08:25, 4th 10:32, 5th 12:15, 6th 14:16, 7th 18:44, 8th 20:24 and the 9th 22:44. Before each station you can hear the same sonic process. Maybe it is the mobile phones establishing connection to BTSs? Very strongly pulsed signals.
A walk around the JR Shinjuku Station, which is one of the most busy train stations in Japan. You can hear the density of the trans-sonical infoscape quite well (wifi, 3G-mobilephones, BTSs, GPS and other unrecognizable signals). Outside the labyrinthine building (9:09 and 14:33) the detektor gets overloaded due to the presence of many BaseTranseiverStations (BTS).
Recorded using HF detektor wandering on the beach at Peenemuende in Northern Germany. Strong signals despite lack of potential signal sources close by. Stark contrasts between detektor signal when held close to the sand and when held high above the head
This is the last part of a international long distance flight from Copenhagen to Tokyo (Narita). Landing at Narita Airport at the end. (Better analysis will follow..)
This recording is made by detektor in a international flight from Copenhagen to Tokyo somewhere above Siberia in near of Mongolia. The signal is comparatively quiet: A lot of Rhythmical and repeating signals.
Detektor flew again to sky above 10000m up. Here how the BTS Signal fades out after 15min, when the place takes off and after some time (18:00), all GSM phones, which are still in operation/switched on try to reconnect after some time. Around 29:36 you can hear a GPS signal.
Compared to european BTS the japanese sound different. Must have some connection to different cellphone frequencies.
Recorded using HF detektor in the apron of Berlin Tempelhof former Flughafen. As previous entry with repetitive signal but now with more present HF background.
Recorded using HF detektor in the apron of Berlin Tempelhof former Flughafen. High frequency background with an intermittent, repetitive loud chirping signal (a set of three peaks) returning every five seconds. The same signal was also heard in many locations around Tempelhof
Detektor started the walk at the main station of Dortmund and walked via Katharinenstrasse (a street name, only pedestarian zone) to Kampfstrasse, where suddenly (04:15) the background noise and the usual BTS signal disappeared, due to an overload of a similar type as near the tv tower of Alexander Platz Berlin. As detektor walked further in direction of Dortmunder U there was almost nothing to hear. At 05:50 detektor passed through a pathway inside/under a building and left the passage at around 07:00. Towards the end of the recording, when arriving at a square in front of Dortmunder U. There were 3 BTS directly standing in front of the detektor (see video). At 07:50 the detektors HF antenna on its board was touched by a human hand, it did that for several times. Actually all the time from then to the end, when there is a signal audible.
There is also a video of the 3 BTS.
Long bus ride from Central Bus Station in Napoli to a bus station at the highway near Bisaccia. The ride is in a crowed bus with a lot of mobile gadgets. At 36:00 long after leaving the urban area of Napoli the BTS signals dissappear for the first time. Around 38:30 the detektor drives clearly audible past a mobile phone base station, most of them are near the highway! See pictures below. From there on the several BTS come and go and get less and less. Around 70:40 – 72:20 there more or less no high pitched base transceiver station (BTS) signal: A silent island amidst of rurality 2.0?
Walk from the Castle (there were many people due to the Festival “Interferenze”) down to the main square (piazza) and round the castle. Very clear GSM signals, because there is no background noise like in urban cities. You can hear clearly the BTS (e.f. 02:20 or 05:12 or ) some kilometers away, but via direct air line (see picture below). A UMTS signal (02:32), interesting signal at 06:25 (what is this?). There are also silent areas e.g. around 09:20, where you can hear the typical GSM localizing signal.
HF recording with detektor on central table in a small, hinterhof studio. No wireless router in studio, one mobile phone (not in use) approximately three metres away from recorder. Household rhythms.
HF recording made on corner of Zolastrasse and Linienstrasse. After a few seconds a very unusual, pure high frequency tone with few punctuations is found at a particular point in space.
HF detektor recorded on bench close to Volksbühne in Berlin Mitte. Much more intense pulsing of all signals compared to close-by Babylon recording.
A very short walk, dance along my favourite spectral zone Karl-Liebknecht-Strasse. HF recording with the detektor and some varying, interesting signals.
HF recording made with no movement, on concrete “bench” close to top of Schendelpark, Berlin Mitte. Interesting low frequency burst patterns.
HF detektor recording made with very little movement, very close to the ground on the corner of Hirtenstrasse and Karl-Liebnecht-Str. Rich spectral ecology with mid-range frequencies.
HF recording made with very little movement, close to the ground outside the Babylon Cinema in Berlin Mitte. Interesting higher frequency pulsing after 20s.
The reason you hear almost nothing at the beginning is supposably due to the massive radiation of the alexander platz tv tower. I walked from close range (50m) of the tower to Radisson Hotel Karl-Liebknecht-Straße 3. You can clearly hear a shift of infoscape when the detektor entered the radisson hotel starting at 03:12 and left the hotel lobby at 10:05 and entered again around 10:30.
