Data Collection, Analysis and reporting for CDMA, GSM,
GPRS and 3G systems

As wireless systems
have matured, much of the drive testing and associated
troubleshooting tasks have become more standardized.
With this in mind, it is much more productive to replace
the manual effort of sending out engineering teams,
with an automated system.
Collection of data with a manual drive test tool is
expensive requiring the full time use of a skilled RF
engineer, a driver and a dedicated vehicle. Automating
the process dramatically reduces this cost and it speeds
up the availability of the data for analysis. In parallel,
the incorporation of modern automatic functions into
post processing software permits routine tasks to be
handled faster and automatically resulting in a more
efficient and lower cost operation. Today, most wireless
customers use manual drive test solutions for a variety
of purposes including collection of data, optimizing
new and expanding networks, troubleshooting problems,
creating and sending management reports and benchmarking
their own performance against that of their competitors.

When changing from
a manual to an autonomous model, most of these functions
will now be automated. Fleet provides data collection
Remote Control Units (RCUs) and are placed in free roaming
fleet vehicles (i.e. taxis, buses, delivery vehicles,
etc.), and remotely programmed to collect data as they
move around the network. In important or busy locations
RCUs are permanently positioned in fixed sites. Data
is collected in all units and transmitted automatically
over the same network (or a different one if required)
to a central database. If required data can be stored
and manually transferred from an RCU by direct connection
to a laptop. This new model of autonomous drive test
allows for increased hours of testing, resulting in
more data collected, more problems isolated, better
quality reports while the skilled RF Engineer’s
time is freed for higher level and more productive tasks. |
Automated
Drive Test Fleet
RCUs can be fitted with multiple channels (the base
platform will support ten!) This allows several networks
to be tested and/or benchmarked using only one RCU per
location. Each channel can be programmed easily and
remotely to perform a customized regime of voice or
data calls to enable testing of all system functions.

Performance
comparison of multiple networks and technologies
(supports GSM/GPRS/CDMA IS95A/B, 1XRTT, 1XEV/DO
and 3G W-CDMA). Records all parameters and messages
of test data with GPS information including layer
3 messages. |
|
Robust
test modules, operating to normal handset standards,
are used to replace traditional unreliable and
fragile phones. This ensures RCUs can run extreme
conditions without interruptions caused by faulty
hardware. |
|
The system
has scaleable architecture allowing growth without
compromising performance, through the use of TCP/IP
and Server/Clients technologies. |
|
A dedicated
channel is used to upload the data to the database,
ensuring the fastest transfer with no interruption
in data collection. The customer can chose the
transmission network and standard from CDMA, WCDMA,
GSM or GPRS. |
