The first is a directional antenna, which is best for devices that are in one room. There are two different types of antennas to consider. Fortunately, it is easy to replace a built-in antenna, opting for a more powerful design. If you experience weak throughput and packet loss, a weak antenna design may be the culprit. Router’s Antenna Can Affect the Connection These options are generally listed under “Transmission Power,” “Eco” modes or “Automatic” settings. If your signal is not strong, check your router settings and turn off low power modes. Some routers have a default “power savings” mode, which saves several milliwatts. Router’s Eco Settings Influence WiFi Speed Connection These generally cost $20 to $100 but are an excellent investment if you want a significant signal boost. If connections frequently drop or speeds are very slow, consider purchasing a wireless repeater. To obtain a strong signal, move any objects that may be hindering wireless waves. Objects, such as metal or water, will also act as a signal block. A general rule is that if you double the distance between the router and client (or device), throughput decreases by one-third of its original strength. The distance between your wireless adapter and router can affect your internet speed. The Laws of Physics Can Challenge Your WiFi Speed Connection If you want to get that extra boost, follow these helpful tips to help speed up your WiFi speed connection. You just upgraded to the latest and greatest internet speed, only to be disappointed because it is not very fast.

Ruckus ups the ante for high-speed, high-capacity WiFi WiFi, the messiah of operators’ brimming networks Michael Lok is South-East Asia managing director at Ruckus Wireless To ensure that you have strong and reliable WiFi connection, it’s vital that you choose a vendor that leverages statistically optimised rate selection algorithms, which jointly adapt both the data rate and antenna pattern together to maximise reliability and throughput. Stable client connections are important in an unstable RF (radio frequency) environment. And when you're guessing, the safest guess is to err on the side of reliability, which sacrifices throughput and capacity and causes other unwanted problems. Without the right algorithm, the optimal rate for any client at any given moment in time is a crapshoot.

WiFi engineers have been led to believe, and – and for better or worse – site survey software validates the belief, that data rates can be reliably predicted based on a metric like RSSI (Received Signal Strength Indicator) or SNR (signal-to-noise ratio). And some product manufacturers use simple metrics like these to determine the right rate. Though often ignored, rate adaptation is a critical component to any high performance system. When it’s tuned properly, a good adaptation algorithm finds the right data rate that delivers peak AP output in current RF conditions – unstable as they are. Rate adaptation is the function that determines how and when to dynamically change to a new data rate. There have been many examples of poor rate control algorithms loose in the wild, in both popular APs and common client devices, that do not actually achieve this monotonic performance, especially when subject to unexpected environmental inputs or certain radio degradations.įinding the right balance between optimum performance and reliability with adaptive data rate algorithms is what separates the great WiFi systems from those that are good enough.

The physical layer data rate selection algorithm is critical to achieving the monotonically increasing relationship shown here up to saturation. Variability in the environment and in the radios themselves makes real-world wireless throughput a random variable that can only be assessed accurately via statistical methods. In fact at some point, usually a few centimetres away from the WiFi access point (AP), you can eventually run into a signal strength so high that the receiver's front-end is unable to process it, at which point throughput will drop precipitously.Īll of the details, especially the scale, of this graph are highly dependent on the capabilities of the transmitting radio, the receiving radio and the environment.

Once there is sufficient signal strength to operate reliably in the maximum supported MCS rate, additional signal strength does not produce additional throughput gains.

The data transfer speed increases up to a point as signal strength increases since higher signal strengths enable the use of higher PHY (PHYsical layer data) rates, also known as MCS (Modulation and Coding Scheme) in modern WiFi.Ī simple way of putting it is to think of different MCS as being somewhat like different gears on a bike or car.
