alternative bts
by Hans Witvliet 05 Apr '11

05 Apr '11

Hi all, A thread on the asterisk mailing list re-triggerd my memory. Last november or so i asked if it might be possible to use a gsm/umts-dongle as a bts. afaicr the general consensus was that it was not possible because the proximity of TX and RX hardware. I have been discussing it with my colleges today and wonder where we were making the obvious thinking-mistake... 1) i know, that certainly at higher powers, the receiver becomes deaf in the vincinity of a (high powered) transmitter, due to cirtuit overload, but in our case we only needs a single miliwatt or even less.... 2) scanning for multiple devices/frequencies is not needed. [the idea is to connect to a single hand-held-device, that is only one meter away, and feed voice through an existing IP-connection] 3) if a dongle is not usable for above reasons as a BTS, why is that same dongle (more-or-less) capable as working as a handheld? Same problems should occur as such, not? http://wiki.e1550.mobi/doku.php If they can tap in the device for audio/sms-client, it should also be possible to do it the other way round, as a single-thread bts.... still puzzled, Hans

Help understanding used power
by Luca Bertoncello 04 Apr '11

04 Apr '11

Hi, list! I'm trying to understand how the options "nominal power" and "max_power_red" work... Last Friday I tried to place 4 BTS in a rectangle of about 100x20 meter and then I examined the measurement reports of a mobile. They are very very bad, and oft it cannot see a cell. Then I tried to change the value of "nominal power" (max_power_red did not changed) and retry to check the measurement reports. No changes... :( Now I'm here in my office with a spectrum analyzer and try to change these values, but what I see in the spectrum analyzer is always the same... I restart OpenBSC after any change, of course! Could you please help me to understand what these values mean and how can I boost the signal? Thanks a lot in advance for your help! -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 23 Fröbelstr. 57, 01159 Dresden Fax: 0351/41381 - 12 _______________________________________________________________________ Impressum: NETZING Solutions AG - Fröbelstraße 57 - 01159 Dresden Sitz der Gesellschaft Amtsgericht Dresden HRB 18926 Vorstand Dieter Schneider - Aufsichtsratsvorsitzender Volker Kanitz USt.Id DE211326547 Mail: netzing.ag(a)netzing.de
