Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Regarding UMTS Model Tuning
In my project
for UMTS model tuning,
We performed CW measurements
using the following:
Nemo outdoor 4 to collect
RSSI, Omni antenna transmitting at 2127.5 MHz with
Now the customer asked us to validate
the model using the following:
TEMS data collection
8.2.1 for live sites to pick up RSCP using Directive
antennas (3 Sectors with mechanical and electrical
tilt) transmitting at 2122.4 MHz
- My questions,
is that logic to validate our model by receiving
modulated signals transmitted from tilted directive
antenna while our model was built depending on unmodulated
signals transmitted from Omni antenna with zero
- What are the rule
of modifying the through clutter losses and clutter
offsets values? When should I give it positive values
and when should I give it negative values?
For TEMS drive test,
- Could we
use the mobile handset as a scanner instead of the
common RF scanner?
- I tried to collect data
in the Idle mode and I noticed that there's a difference
between TEMS route "shown in TEMS Map window" and
exported log file table "shown in MapInfo".......the
difference is just a repeated data which cause nonsense,
so why I got these repeated data? And how could
I disable it?
