54 PRODUCTS Handheld Mobile WiMAX test solution network deployment, installation and maintenance applications Engineers can use the Mobile WiMAX Demodulator to analyze OFDMA signals and display detailed measurements for evaluating transmitter modulation performance. The measurement screens that can be displayed are constellation (QPSK, 16 QAM, 64 QAM), spectral ﬂatness, EVM versus subcarrier, EVM versus symbol, DL MAP with automatic decoding, and modulation summary. A channel power monitor measurement is part of the Mobile WiMAX OTA option and allows a speciﬁc channel’s power over time and speciﬁed interval to be analyzed. This feature can be combined with a GPS feature so that measurement data can include GPS location and time data for plotting on a map. The company’s Master Software Tools enables easy integration into MapInfo Professional and Microsoft MapPoint maps. All the options can be used with the MT8222A BTS Master, and the Spectrum Master MS2721B, MS2723B, and MS2724B analyzers. Weighing under 4 kg, the MT8222A delivers a small, lightweight and economical handheld solution for complete 2G/3G/4G base station testing. The MS2721B, MS2723B, and MS2724B are advanced ultra-portable 7.1 GHz, 13 GHz, and 20 GHz spectrum analyzers with broad frequency coverage, high sensitivity and a wide selection of resolution bandwidths.

Incorporated into its BTS Master and Spectrum Master platforms, the Mobile WiMAX test capability provides ﬁeld engineers, technicians and contractors with an easy and highly accurate method for conducting RF, demodulation, and Over-The-Air (OTA) measurements on WiMAX signals. The Mobile WiMAX measurement capability has been designed into three options to provide users with ﬂexibility when conﬁguring their instrument. A Mobile WiMAX RF Measurements option can be used to measure the transmitted signal strength and signal shape of a transmitter. With this option, the handheld analyzers can conduct Channel Spectrum, Power versus Time (with 5 ms and 10 ms frame lengths), and ACPR measurements. RF summary screens can also be displayed. Network protocol for low-power RF networks targets simple implementations of less than 100 nodes Texas Instruments has released the SimpliciTI network protocol, a proprietary low-power RF protocol targeting simple, small RF networks (less than 100 nodes). The network protocol was designed for easy implementation with minimal microcontroller resource requirements. It runs out-of-the-box on TI’s MSP430 ultralow-power microcontrollers and CC110x/ CC2500 RF transceivers. With SimpliciTI network protocol, MCU resource requirements are minimal, resulting in lower system cost and longer battery life for low-power RF networks. More complex mesh networks that need routing typically require 10x the program memory and RAM to implement. Despite the modest resources required, the network protocol supports peer-topeer communication, the option to use an access point to store and forward messages and range extenders to extend the range of the network to four hops. It also supports a wide range of low-power applications including alarm and security, automated meter reading, home automation and active RFID. SimpliciTI is a perfect complement to ZigBee, which is designed for larger networks with mesh routing and standardised proﬁles.
