Microwave Vision Group launched a new antenna measurement test system for “4G” devices, with up to three-times faster measurement capabilities and a broader dynamic range in passive antenna measurement mode.
The new SG 24 system is compliant with CTIA OTA performance specs, for testing mobile device conformance at high throughput or high frequencies for LTE and Wi-Fi 802.11a and 802.11n protocols.
The company also demonstrated its EME Spy 140 this week, which is a portable, personal device for measuring electromagnetic field exposure on predefined frequency bands. The device also features Bluetooth options in its real-time kit, so that a user can view his or her measurements in real time on an Android device.
Spirent Communications launched a performance measurement system for HD voice and voice over LTE, the Spirent Nomad HD. The equipment performs HD voice-quality measurements and call performance testing, incorporating perceptual objective listening quality assessment (POLQUA), which is a methodology standardized by the ITU that allows for comparison between circuit-switched and IP-based voice from the same service provider.
Spirent’s divisional VP, Des Owens, said that the Nomad HD allows operators to “ensure that VoLTE delivers the same or better voice quality as the previous generation of voice services,” which has been a key factor in the deployment of the technology. The test solution supports all devices and can be configured for both lab or field tests, Spirent said, and operates in two modes for narrowband or super-wideband communications.
Mike Barrick, business development for Anritsu, said this week that the company expects to see deployments of VoLTE before the end of the year, given the amount of VoLTE testing going on currently. The company demonstrated the first commercial device testing of LTE-Advanced carrier aggregation with a Netgear device this week, as well as its Link Master Drive Test discussed in this video with RCR’s Jeff Mucci.
JDSU has a new RANAdvisor platform and handheld, which includes real-time results rather than waiting for the end of a four-hour test. The solution can also be used in conjunction with JDSU’s CellAdvisor base station analyzer for testing voice, data and web services across small cells — which were a major focus of the conference this week. with Verizon Wireless announcing plans to work with Ericsson on small cells. CellAdvisor also received an update, with the company’s new JD780 platform able to test within 35 seconds of being turned on, and switching between modes in three seconds, JDSU said.
The instruments are designed to detect low-power interference and test either wired or wireless microwave backhaul for network sites, as well as MIMO performance, indoor and outdoor cell site testing and transmission coverage, and RF interference detection, identification and location.
