Operators Become More Equipped to Troubleshoot 3G Networks
October 26, 2003
Tektronix, a provider of test, measurement and monitoring solutions for
mobile network operators, announced the latest addition to its industry
leading base station field test tool. The new feature enables over-the-air
(OTA) analysis measurements for W-CDMA via the most flexible toolbox on
the market.
3G mobile communications networks require significantly more Node-Bs
(base stations) than 2G networks. As such, field technicians must be able
to "scan" multiple neighboring base stations for interference that may
affect network performance. Tektronix' NetTek Field Tool is the market
leading handheld instrument used for base station troubleshooting, and
today adds the W-CDMA Scrambling Code Analyzer, Option WS1, to enable
OTA measurements for quick identification of problems in 3G networks.
"With W-CDMA networks beginning to go live around the globe, network
operators must be equipped to provide the best possible quality of service
to their customers without increasing the cost of operation," said Mark
Kulper, General Manager, Wireless Field Test, Tektronix. "By adding the
scrambling code analysis capability to the NetTek field tool, Tektronix
is enabling operators to effectively install and maintain their 3G networks."
Scrambling Code Analysis Critical in 3G Networks
Each sector within a W-CDMA Node-B uses a different scrambling code,
and technicians need to be able to identify and "source" these codes as
a first step to locate any interference problem. With the NetTek's new
Scrambling Code Analyzer, technicians can quickly identify different scrambling
codes, analyze power levels and determine the relative strength of network
signals. As such, maintenance technicians can easily evaluate co-channel
interference and any changes from neighboring base stations. In the case
of installation, the Scrambling Code Analyzer can determine the effect
of making changes to, or adding, a base station to their network.
With Tektronix' NetTek field tool, which is recognized for its flexibility,
light weight and modularity, technicians can easily walk about the base
station and perform "pollution" analysis -- including power levels of
the potentially interfering base station -- enabling the technician to
detect the approximate direction from which the interfering pilot signals
are coming and address any network interference immediately.
About The NetTek Field Tool
The NetTek BTS field tool is a rugged portable platform with multi- standard
measurement capability. The NetTek fills the gap between expensive, full-compliance
testing tools and low-cost instruments designed to perform only one measurement.
The instrument's modular architecture supports a range of BTS transmitter
measurements for standards including UMTS/W-CDMA, cdmaOne (IS-95), cdma2000,
cdma2000 1x EV-DO, GSM and IS-136. The instrument's Windows-based user
interface simplifies operation in the field. The compact battery-powered
tool, which weighs just over 12 lbs (4 kg), is to transport to remote
sites. In addition, the NetTek platform is unique in the industry by virtue
of its ability to address antenna, backhaul (T1) and RF test requirements.
