What's Happening In Short-Range Wireless?
By
Louis Frenzel, Communications/Test Editor
There are literally dozens of methods used in transmitting data wirelessly over short distances. Here is a look at what is happening with some of the more commonly used standards like Wi-Fi, Bluetooth, UWB, and ZigBee.
As short-range wireless technologies have gotten speedier over the years, most companies have been seeking ways for their technology to gain a foothold in the high volume consumer electronics market to transmit video over short distances to eliminate the gaggle of cables we’ve gotten used to. Existing technologies like 802.11n Wi-Fi and WiMedia's Wireless USB ultra wideband (UWB) have potential in this application but have limitations as well.
Software Option Delivers Comprehensive LTE Signal Analysis
The 3GPP LTE modulation analysis option for the company's 89600 Series Vector Signal Analysis software offers R&D engineers LTE analysis from baseband to antenna, on digitized or analog signals for both uplinks and downlinks.
The Model 7142-428 digital transceiver packs a multiband digital down converter (DDC) and an interpolation filter, making it a complete software radio system (SDR) in a COTS PMC/XMC module.
To aid educators in teaching analog and digital communication fundamentals, National Instruments and Emona Instruments team up to offer an add-on telecommunications module, the Digital Analog Telecommunications EXperimenter (DATEx), for the NI Educational Laboratory Virtual Instrumentation Suite (NI ELVIS).
PMC/XMC Receiver Sets Benchmarks For ADC Capabilities
Set for deployment in harsh environments, the ICS-8551 ADC PMC/XMC digital-receiver module offers both two- and four-channel operation with sampling frequencies of 1.5 GHz (four channel) or 3 GHz (two channel) for software defined radio (SDR) applications.
