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.
Although Wi-Fi operates at different frequencies than the ones used by the DOCSIS system, many interference cases have been observed. The interference can have an impact on the DOCSIS system, on the Wi-Fi system or on both.
We need Wi-Fi everywhere! People are expecting whole-home coverage and if new features like fancy antennas or beamforming technology don't cut it, strategically placing additional Wi-Fi gear in a home should increase the coverage area. However, after setting it all up, these secondary access points, repeaters and other equipment should play nice and act as one big happy network that we can use throughout the home. To help realize this, the Wi-Fi standard provides the Wi-Fi seamless roaming functionality. Let's find out the do's and don'ts in this blogpost.
