This is the indoor coverage of Alstertal Einkaufszentrum. It is the first LTE station operating on 2100 MHz (Band 1) that I could observe. There are three sectors installed (19/20/21) where the signal is strongest at the escalators.
Some operational info: Band: 1 Bandwidth: 5 MHz DL Frequency: 125 UL Frequency: 18125
Of course there are no speed records possible with 5 MHz of bandwidth, but the speedtests I have taken were quite satisfying: http://www.speedtest.net/iphone/2382922388.png I remember the indoor 3G network to be congested, so this really is an improvement. Voice calls via VoLTE worked flawlessly.
Note that band 1 seems to be very low priorized. Even weak band 20 cells from the macro network were preferred.
The track area of 42409 is a bit unexpected for this place, but the 3G cell (HXUC97) has always been located in LAC 1022, which is consistent with the rest of the TAC 42409. All cells in the track area 42441 (that I would have expected) are part of LAC 1401 3G-wise.
GSM coverage is provided by HXBC97 in location area 2215.
