Imec transmitter has 10x power reduction

image

Imec has developed a 1.3nJ/b fully digital polar transmitter optimised for IoT applications and the novel IEEE 802.11ah Wi-Fi protocol, with a ten-fold power reduction as compared to state-of-the-art OFDM transmitters. The Wi-Fi Alliance has introduced the HaLow (TM) designation for the new low power, long range Wi-Fi protocol IEEE802.11ah, developed by the IEEE standardization committee. This new protocol is ...

Intel and Qualcomm announce WiGig interoperability

image

Qualcomm and Intel have announced interoperability between their WiGig products. This will help pave the development of 802.11ad WiGig devices that connect at speeds of up to 4.6 Gbps. Bringing spectrum in the 60 GHz band to Wi-Fi 802.11ad will address rising data demand in homes, enterprises and carrier networks. 802.11ad enables 4K display connectivity to tri-band (2.4 GHz, 5 ...

LHC to use RapidIO interface for big data transfers

Large Hadron Collider (CERN)

CERN, Europe’s nuclear research facility, has worked with US-based interface IC firm Integrated Device Technology to create a data bus platform with the necessarily low latency needed for data analytics at the organisation’s Large Hadron Collider (LHC) and data centre. CERN recognised it needed to improve overall data acquisition and analysis for the massive volumes of data collected by the experiments ...

Energy harvesting moves to 2.4GHz for IoT designs

Graham Martin

The latest version of the ZigBee low power radio standard will include for the first time support for energy harvesting as defined by the EnOcean Alliance. ZigBee 3.0 will be an open specification that is intended to support energy harvesting wireless communications operating in the 2.4GHz for the first time. “We are very excited that the EnOcean Alliance is bringing its ...

IQ modulator design needs measurement accuracy, says Linear Tech

13jan16evmfig1

How to optimise digital modulation accuracy in an IQ modulator? Bruce Hemp and Peter Stroet from Linear Technology describe how a vector signal analyser helps optimise EVM performance of the LTC5598 direct quadrature modulator. EVM, or error vector magnitude, is essentially a scalar measurement of digital modulation accuracy, an important figure of merit for any source of digital modulation. Low ...
