Professor Per-Simon Kildal and Bluetest will give a half day course at IEEE AP-S 2008 in San Diego, 6 of July 2008. The title of the course is "Testing Wireless Devices in Reverb Chamber". The course material is based on several years published and unpublished material related to measurements in the small Bluetest reverberation chambers as well as larger reverberation chambers.
Bluetest´s distributor for the ASEAN countries, ST Electronics (Info-Comm Systems), will demonstrate the capabilities of Bluetest´s reverberation chambers in the Swedish Pavilion (booth #3H2-03) at CommunicAsia 2008 in Singapore, June 17-20.
Learn more about making direct measurements of diversity gain and MIMO capacity in only one minute using the Bluetest High Performance (HP) reverberation chamber. Antenna efficiency and TRP per channel can also be measured in only one minute. TIS measurements take about 10 minutes/channel for GSM and WCDMA.
Bluetest is releasing new software for Bluetooth TRP and TIS measurements. In the same measurement sequence, it is possible to obtain both the TRP and TIS value of a Bluetooth device in less than 3 minutes/channel.
At the 2008 International Workshop on Antenna Technology iWAT in Chiba, Japan, Bluetest´s CEO Mats Andersson presented the invited paper "Three Fast Ways of Measuring Receiver Sensitivity in a Reverberation Chamber" by Mats Andersson, Charlie Orlenius, and Per-Simon Kildal.
Bluetest is happy to announce an order for High Performance chamber no. 10. It is also the first order to Taiwan. Bluetest has previously delivered reverberation chambers to several Asian countries which have companies focused on wireless devices with small antennas, among them Korea, Japan, China, and now also Taiwan.
In their latest issue, Microwave Engineering Europe (MWEE) publishes an article highlighting the benefits of the reverberation chamber. The article is authored by Bluetest CEO Mats Andersson and gives a thorough background to measurements of devices with integrated small antennas.
See a web version of the January/February issue of MWEE here, the reverberation chamber article is found on page 24.
With the delivery of HP chamber no. 8 in December 2007 Bluetest has delivered TRP and TIS software for GPRS/EDGE and HSPA. The TRP measurements take one minute/channel with an accuracy of better than 0.5 dB standard deviation, and TIS measurements take about 10 minutes/channel.
Software for measuring GSM, WCDMA and CDMA2000 with the same speed in the HP chamber is available since earlier. Software for Bluetooth measurements is planned to be ready in March 2008.
Bluetest is happy to announce its first order to Japan for High Performance reverberation chamber no. 9. In connection with the delivery of the chamber in early March 2008, Bluetest´s Japanese distributor Toyo Corporation will arrange a seminar to introduce the Bluetest products to wireless companies in Japan.
Taiwan has many of the world leading companies developing and manufacturing wireless devices with small antennas. “Bluetest is very happy to add QuieTek, which is a well known Taiwanese EMC and wireless certification lab with a large customer base in Taiwan and China, to its list of Asian distributors” says Mats Andersson, CEO of Bluetest AB.
The Swedish paper Elektronik i Norden publish an overview article of why reverberation chambers are to be preferred for measurements of mobile phone antennas, as well as for all wireless devices with small antennas. The article in Swedish is available in Elektronik i Norden no. 17 at page 29. A translation into English can be found here.
