Here are some warmer color profiles for W230SS that I uploaded due to request.

Installing PHP 5.4 on Solaris 11
$ wget -O php.tar.bz2 http://link/to/the/php/file
$ tar xvjf php.tar.bz2
$ cd php-5.4.*
$ ./configure –with-apxs2=/usr/apache2/2.2/bin/apxs –prefix=/usr/php/5.4

$ gsed -i.bak ‘s,\-i \-a \-n php5 libphp5\.la,-i -n php5 libphp5.la,’ Makefile

make a copy of php/php5.3.conf and rename it to php5.4.conf
Replace in the file: 5.3 with 5.4
and replace the original module with: LoadModule php5_module libexec/libphp5.so
then change php.conf and redirect the includes to the new php5.4.conf file
Changing boot device on SPARC devices
Halt the system using init command. poweroff will completely shutdown the system and will give no PROM prompt so only halt it.
init 0
Use show-disks to select one of the disks and execute boot {disk} command.

GSM Amplifier
The High Power Amplifier for my Tactical GSM network has arrived, it almost took 2 weeks to get it delivered.
I bought the amplifier from Israel. Although it is manufactured in Korea.
It gives 42db avarage gain and allows up to 10 watts of transmit power.
Also it is noticable that it has d-sub 3w3 power connector.
I intended to buy a proper connector for the cabling but I gave up, I am going to rely on coils and and duct tapes
But it consumes near 300w of electricity at max, so I had to buy a separate power supply for it.
It isn’t easy to come by a 27v power supply but I was lucky enough to find one.
LTE EARFCN에 대해
블로그 로그를 보다가 LTE eARFCN이란 키워드로 방문하시는 분이 많은 것 같아 간단히 글을 남깁니다.
GSM 같은 셀룰러 네트에서 와이파이의 채널과 같은 의미를 가진것이 ARFCN입니다
Absolute Radio Frequency Channel Number 의 약자죠.
기지국과 휴대폰이 통신을 할 때 쓰는 업링크와 다운링크 채널을 정해 놓은 것입니다.
인접한 셀들끼리 비슷한 채널을 이용해 신호를 송출하면 혼선이 일어나기때문에 각 섹터마다 기지국은 다른 ARFCN을 이용해서 서비스를 하게 됩니다.
이것이
GSM과 같은 2G 망에서는 ARFCN으로
UMTS와 같은 3G 망에서는 U-ARFCN으로
LTE와 같은 4G 망에서는 E-ARFCN으로 불리는 것입니다.

GSM frequency band table for reference
LTE Reference Signal Power
Reference signal received power (RSRP) identifies the received signal level of the Reference Signal. It is defined as the linear average over the power contributions of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth.
A minimum of 95% of the weighted average of the LTE design service area Cluster or Polygon must meet the RSRP targets specified above. The criterion of 95% is based on a weighting using the same clutter weights used for traffic spreading. The target specified above is after taking into consideration the indoor loss values assigned per clutter type In-building losses enabled.
