Excentis launched a brand-new service for testing Wi-Fi access points. The unique testing approach in a real-world environment, a first in Europe, provides both operators and manufacturers with representative parameters for assessing the performance of Wi-Fi access points.
Introduction This program focuses on the Wi-Fi component embedded in a cable modem or gateway. Overlap with Wi-Fi Alliance testing is avoided: this testing starts where the Wi-Fi Alliance certification stops. Support of a community Wi-Fi service was one of the main drivers for this program, but the...
Excentis offers a unique testing service in a real home — a realistic, static, residential environment with controllable interference. This setting enables the customer to statistically compare Wi-Fi access points, as the performance is measured by a robot from different physical locations in the...
home_gateway.jpg Cable operators are now deploying advanced home gateways instead of simple cable modems. New advanced services, the transition to IPv6 and the ever increasing number of connected devices push such gateways to support a multitude of services and devices — fundamentally increasing...

This year at ANGA COM, Wim De Ketelaere will share insights into the newest Wi-Fi technologies during the “Wi-Fi – Key to new business session” on May 21st, 2014. Instead of a theoretical explanation on the operation of the latest Wi-Fi technologies , Wim will present how the different technologies...
With smartphones, tablets, laptops and smart TVs ruling the world, sharing and streaming content from one device to another over Wi-Fi becomes more and more important. The list of new protocols to achieve this goal is still booming. Companies are trying to convince the customer with promising terminology like Apple® AirPlay®/AirDrop®, Samsung AllShare™, Intel® WiDi, Sony® One-touch Mirroring™ and so on. But how do these protocols work; how do they relate to Wi-Fi CERTIFIED™ standards like Wi-Fi Direct®, (T)DLS® and Miracast®; and most important: what about interoperability? Let’s find out!
Wi-Fi has become the preferred technology for in-home connectivity, but sometimes it’s needed to connect a wired device (e.g. a printer) to a Wi-Fi network using a Wi-Fi bridge. In a wired world bridges are used very often and typically don’t cause much problems. In the Wi-Fi world the situation is slightly different, read on and find out why!
While most of us are using 802.11n devices or looking to replace them with 802.11n/ac devices, there are still some 802.11b clients wandering about. These old 802.11b devices can seriously impact the performance of our Wi-Fi networks on the 2.4 GHz band. How much? Let’s find out.
To check our Wi-Fi signal reception, we tend to look at the signal notification icon of our devices: the more bars, the better the signal. But more often than not, the amount of bars doesn’t give us a good indication of the quality of our connection. We've all had situations where 4 or more bars are lighting up, but websites are still loading agonizingly slow. To make things worse, a lot of professional Wi-Fi planning and comparison tools use this same signal strength metric as a substitute for Wi-Fi throughput! This blog post will show that the Received Signal Strength Indication or RSSI of a link (which is basically a numeric value for the number of bars) doesn't correlate well with the throughput that can be achieved on that link. In other words, big investment decisions in Wi-Fi infrastructure turn out to be based on paltry data at best.
