bkil vs. programming

I've just realized that stock Android 2.1 on the U20i (so called "mimmi") discovers Wifi networks by  passive scanning , and only sends out a few probe requests as an acceleration in case of opening the network list menu after waking up. On the other hand, it seems that both Pulse mini (Huawei U8110 with Android 2.1) and Mango (Xperia mini pro SK17i with Android 4.0.4) use normal active scanning. Common wisdom tells you that passive scanning potentially uses more power. This can happen because the receiver's low noise amplifier and processor can use as much power as the transmit circuit. This is especially plausible because maximum transmit power usually shouldn't exceed 100mW anyway (actually 20dBm EIRP ) which is in the ball park of the wireless chip's total consumption already, let alone the whole chipset or mobile device. Active probing involves sending out a probe request on each channel and listening for a response for a limited short interval. I guess...

Using Lubuntu 12.04 for connections to icewm on Ubuntu 12.04. The exact configuration involves hosting a pulse sound server on each thin client , and configuring applications on the remote desktop to pipe back sound to the respective thin client. A trusted environment is assumed here, so please refer to the PulseAudio Network documentation on freedesktop.org and various general security guidelines (firewalls, tunnels, IPsec, VPN, etc.) if you're planning anything serious. Thin client setup: Purge any left over configuration: rm -Ri ~/.pulse Install PulseAudio: sudo apt-get install pulseaudio dbus-x11 Enable local sound access (not sure if needed): sudo adduser $USER pulse; sudo adduser $USER pulse-access then log out and log in again Give local and network access to the sound: cp -t ~/.pulse/ /etc/pulse/default.pa # APPIP="type application server IP address here" echo "load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1/32;$APPIP/32" >...
