| 14^th April, 2016 | AT4 wireless (now a DEKRA company) and octoScope are collaborating for the development of advanced performance solutions aiming at the uprising technical challenges behind Wi-Fi and LTE-U coexistence.

The AT4 wireless Performance Testing Platform has now the ability to control the octoScope programmable attenuator and turn table for covering a wide variety of performance tests such as LTE-U and Wi-Fi Coexistence and Throughput versus Attenuation versus Rotation.

The integration of the octoBox modules in the AT4 wireless Testing Platform provides many functional and usability features. We can highlight:

• Single Graphical User Interface for scripts definition and KPI reporting

• QoS and QoE KPIs in RF repeatable environment

• Automated test suite for Below Energy Detect Wi-Fi and LTE-U coexistence measurements

AT4 wireless Performance Testing Platform Highlights

• Graphical User Interface

• Packet Level KPI Resolution

• QoS KPIs: Throughput, One-way Delay, One-way Jitter, and One-way Packet Loss

• QoE KPIs: YouTube, Spotify, Web Browsing, File Transfer, Facebook

• Highly configurable traffic generator: Constant Bit Rate, Ramps, Loops and Bursts.

• Pass/Fail criteria per data flow based on KPI average and percentile

• Power supply control for device rebooting between test cycles

• Real WLAN Access Points control for roaming scenarios

octoScope stack Highlights

• Stand-alone compact industry-standard benchmark

• Wi-Fi (802.11a/b/g/p/n/ac), cellular (GSM, UMTS, LTE, LTE-Advanced), Bluetooth, ZigBee, etc.

• Excellent MIMO-OTA environment optimized for very high throughput

• Multipath emulation of IEEE standard 802.11 indoor environment

• Supports up to 8x8 MIMO of any channel width in the 700 MHz to 6 GHz frequency range

• Adds realistic multi-channel interference using the iGen™ interference generator module

• Can be left running for days for extensive averaging or fine resolution of attenuation and rotation steps or multiple interference scenarios
