Adeunis’ wireless audio-conference system in athletics tracks
The Adeunis RF wireless audio-conference system is now making an
entry on the athletics tracks through the Franche-Comté
Athletics League. During competitions, it provides triangular
communication between two groups of people: the starter,
electric timer and secretariat on the one hand and the overall
referee and competition and race referees on the other. The
product was chosen particularly for the "open mike"
communication concept, which allows all users to talk when they
want, without having to wait their turn or use an activation
accessory to initialise communication.

Airwave wireless audio and video transmission system from
LPRS
Airwave audio and video wireless connectivity systems are
available from LPRS. The Airwave AWV367/368 -10dBM system
operates at 2.4GHZ and has an indoor range of 30m. Complete with
transmitter, receiver, power supplies and SCART connectors, the
Airwave system may be set up and configured in minutes. For good
reception the operating channel may be changed through a DIP
switch and integral, adjustable antennas are fitted.

40-MHz bandwidth signal analyser
Rohde and Schwarz’ FSV mid-range signal analyser has an analysis
bandwidth of 40 MHz, enabling it to cover a wide range of
wireless standards from 3GPP LTE up to WLAN 802.11n. Offering
1,000 sweeps/sec in remote-control mode, the instrument is up to
five times faster than other signal analysers in its class, the
company claims. The FSV’s total measurement uncertainty is 0.3
dB up to 3.6 GHz and 0.4 dB up to 7 GHz. The base unit provides
a complete set of functions such as the measurement of channel
power and adjacent channel power or spectrum emission mask, as
well as a selection of filters and detectors.

Keithley adds WiMAX testing
Keithley Instruments has extended its RF test capabilities to
include WiMAX signal testing, with a set of signal creation and
analysis tools. Keithley has developed a new architecture for RF
test products that employs softwaredefined- radio techniques,
with extensive use of DSP (digital signal processing). This, the
company says, simplifies extending its measurement capabilities
to add support for new signal standards without requiring
expensive hardware upgrades or different instrumentation; in
this case, IEEE802.16e mobile WiMAX Wave 2 testing with up to
4X4 MIMO channels.

Meeting Serial Rapid IO Architectural Trends
Increasing mobile data traffic demands, driven by subscribers,
will quickly require a shift to deploy 3.5G and 4G base
stations. The architectures in these next-generation base
stations demand high-bandwidth backplanes for multiple baseband
cards. In turn, the baseband cards require clusters of multicore
digital signal processors for higher baseband processing
capability. To match the increase in system performance, high
bandwidth links are needed to interconnect multiple DSPs.

“Connectivity hub” chip bundles 4 wireless functions
The latest in CSR’s BlueCore series of wireless chips is
BlueCore7, which the company now describes as a connectivity hub
for mobile phone handsets, combines four radio technologies on
to one IC. It integrates Bluetooth, Bluetooth low energy (otherwise
known as Ultra Low Power Bluetooth or WiBree), FM radio –
receive and transmit – and GPS. The Bluetooth radio complies
with the v2.1 + EDR standard, with +10 dBm transmit power and
-91 dBm receiver sensitivity for best range and “cross-body”
performance (handset to headset).

BAW filters offer high selectivity at 2.4 GHz
US-based company Skyworks Solutions has announced a series of
parts that it believes will be required to enable the
co-existence of wireless LAN and WiMax networks. The bulk-acoustic-wave
(BAW) devices are band-pass filters that operate at the 2.4-GHz
frequencies used by both standards, and that provide the
selectivity to reject signals in nearby channels. The company
intends the devices for applications in customer-premises
equipment. Skyworks develops integrated RF solutions for an
array of air interfaces and system architectures.

Wireless sensor networks support IP traffic
Jennic has introduced a single-chip implementation for 6LoWPAN
low-power wireless IP, routing IP traffic over low-power
wireless networks. Jennic supplies solutions in both ZigBee and
generic IEEE 802.15.4 wireless areas; this introduction is part
of the latter. The company says that in many cases, in
industrial and commercial-building networks, the extended-mesh-network
(as proposed in ZigBee) may not be the ideal implementation. A
more realistic structure to install wireless sensor networks in
large buildings is local cluster of up to 50 to 70 nodes,
connected wirelessly, with the clusters connected to a wired
backbone.

European Wireless Technology Conference (EuWiT)
The European Microwave Association announces the first European
Wireless Technology (EuWiT) conference, formerly ECWT (European
Conference on Wireless Technology) which will be held from 27 to
28 October in Amsterdam, The Netherlands, as part of the
European Microwave Week. This conference covers a wide range of
topics in wireless communications including key technologies,
components and subsystems, antennas and propagation, systems and
signal processing as well as applications and standards.

Wireless Congress 2008: Systems & Applications
As they increase in performance, wireless technologies are also
becoming more complex. No matter whether in the industrial,
consumer, communication or computer sector. Innovation is
progressing in a variety of directions, encompassing a whole
number of different applications, markets and standards. The
specialist's thirst for information is thus growing at a fast
pace. The magazine Elektronik, the organizers of the electronica
show and the German Electrical and Electronic Manufacturers'
Association (ZVEI) are consequently staging the 5th Wireless
Congress 2008: Systems & Applications in Munich on November 12 -
13, 2008.

Understanding
the Role of Wireless Technologies for Next-Generation Telematics
Applications
The increasing variety of portable
wireless broadband technologies brings up the question of
potential applications and additional revenue streams in the
telematics space. The key questions answered in this report
include: what telematics applications have the greatest
potential for widespread adoption; what opportunities does
ubiquitous wireless broadband enable for telematics and what
problems exist; and which wireless technologies are suitable for
telematics.

Research forecasts total mobile payments to grow nearly ten
fold by 2013
Purchases via mobile devices of digital and physical goods,
contactless NFC (Near Field Communications) transactions and
money transfers will together generate transactions worth over
$600bn globally by 2013, according to Juniper Research's Mobile
Payments Study. The figure represents the gross value of all the
items being purchased or the value of money being transferred.
