Rohde & Schwarz Equipment Helping P3 Eliminate RFI
Munich, Germany — The Rohde & Schwarz PR100 portable receiver has been selected by P3 Communications, Columbia, Maryland, as the instrument of choice for identifying and eliminating RF interference in 3G and 4G/LTE mobile networks. With units deployed across key mobile markets in the U.S., P3 Communications’ mobile network main- tenance and engineering team is able to quickly and effectively identify RF interference negatively impacting customer quality of experience (QoE). Designed to support high data rates up to
300Mbit/s in the downlink and 75Mbit/s in the uplink, commercial LTE service is now widely available throughout the United States. When it comes to RF interference, LTE introduces some unique and very different challenges compared to 3G technologies. The introduction of new frequency bands, new higher order modulation types that require a “clean-
Sensirion Launches Next Gen Sensor
Stafa, Switzerland — Sensirion AG has introduced its latest temperature sen- sor, the STSC1, proving once again that high measurement accuracy can be combined with an extremely attrac- tive price-performance ratio. The latest generation of temperature sensors pro- vides high accuracy, low power con- sumption and minimal size.

Temperature sensor. The STSC1 temperature sensor
has the potential to build on the highly successful SHTC1 humidity and tem- perature sensor. Its successor will inherit in particular its high-precision temperature measurement and remarkable value. The STSC1 focuses on applications
that require very precise temperature measurement. It is suitable for consumer electronics, Internet of Things and smart home applications, as well as for data log- gers and thermostats. With compact dimensions of just 2 x 2 x 0.8mm, low power consumption and supply voltage of 1.8V, in addition to its easy handling, the STSC1 provides a fully calibrated and linearized digital signal to a microcon- troller. The sensor measures tempera-
tures from –40 to +125°C with a typical accuracy of ±0.3°C. The fully calibrated sensor features an I2C interface and is reflow-solderable. It is suitable for standardized industrial series produc- tion of electronic de vices and can be successfully integrated into complex
applications. Contact: Sensirion Inc., 2801

er” RF environment, wider channel bandwidths that need to be checked for potential interferers,
and the widespread use of remote radio heads or DAS systems that are more difficult to access to search for interference at the base-station, may all contribute to making RF interference hunting more difficult within LTE networks. According to P3, as with many new technology roll-outs, mobile operators’ initial concerns are around getting the basic technology working first. But as the technolo- gies begin to mature, operators quickly turn their attention towards performance and optimizing the
customer experience. Contact: Rohde & Schwarz USA, Inc., 8661A
