Wireless, remote, and mobile connections have also broadened the range of devices accessing the internet and participating in networks. The rise of the Internet of Things has facilitated a staggering proliferation of internet-connected devices, which will number 24 billion —or four devices per human being—by While smart technologies equipped to communicate and share useful data with one another simplify many processes and often better our daily lives, they also increase the volume of networking devices and complicate network infrastructure.
This, in turn, can lead to higher potential for network failure. For this reason, network performance monitoring is a crucial—and perhaps the fundamental—responsibility of IT departments. The implementation of a robust Wi-Fi analysis solution is key to preventing expensive network downtime from befalling your business. Consequently, Wi-Fi tools are necessary for the sake of assessing and maximizing Wi-Fi performance, helping drive organizational productivity and profitability.
Wi-Fi analysis is the process of collecting, synthesizing, presenting, and evaluating data from the wireless network to optimize its function.
Wi-Fi analyzer software executes this analysis by tracking and reporting key performance metrics, enabling IT departments to monitor network health, identify problems before they develop, furnish solutions, and decrease MTTR mean time to repair issues.
Usually, analysis-based optimization entails gauging, and then improving, transmission speed, signal strength, and reliability. While all IT professionals see the value of maximizing network uptime, fewer know where to start when it comes to maintaining steady levels of high performance specifically on the Wi-Fi end. Many factors affect how well your Wi-Fi works, and not all of them are entirely within the purview of Wi-Fi networks themselves.
For this reason, IT administrators must look for the root cause of networking problems so they can identify the best solution, whether it means changing the Wi-Fi router settings or contacting the internet service provider ISP. Wi-Fi also enables network devices to access the internet, which is itself a decentralized and massive network connecting millions of computers worldwide. Wi-Fi is merely a means of accessing the internet, not the internet itself—a crucial distinction when it comes to evaluating network health.
When organizational members complain to IT about slow internet speeds, several things could be at play. This could be corrected by paying for higher speeds or switching to a new provider with a more reliable service.
If the ISP is not the source of a poor internet connection, then the issue may very well be with the Wi-Fi itself. If internet or inter-device connections are lagging, it could be due to noise, or interference within the network. The noise comes from various sources.
Many devices within range of the router emit waves that can clash with the Wi-Fi. These include microwaves, cordless phones, power cables, baby monitors, fluorescent lights, and other Bluetooth-equipped and wireless devices.
A good deal of network noise comes from Wi-Fi interference. Many Wi-Fi networks use the same channel within a radio wave frequency spectrum, or band the most common bands for standard Wi-Fi networks are 2. As a result of sharing both a channel and a spectrum, routers placed near each other produce overlapping coverage areas, causing radio wave interference affecting the Wi-Fi signal and, consequently, transmission rate. Weak signal strength can arise for a few reasons. First, as previously mentioned, noise can alter the radio wave, causing the signal to falter in certain zones of a coverage area.
Second, radio waves travel more easily through some media than others, meaning the materials used to construct a building affect the Wi-Fi range, and placing a router heedless of its surroundings can hinder reception. Wi-Fi can travel through obstacles made of:. Designing a Wi-Fi network with adequate capacity to support the number of devices required is a fundamental step in IT infrastructural planning. The Microsoft Xbox controllers utilize their own 2.
Some of the console's RF is frequency-hopping while the game controllers broadcast on their own frequencies. The duty cycle of these devices is fairly low, but can cause some performance degradation to a wireless network.
Some audio systems use the 2. The frequency utilization is constantly high and can cause large dead zone areas in indoor and outdoor environments. These analog systems may be mounted in the ceiling and can be difficult to track down. Similar to wireless audio systems, the subwoofers typically create 1 to 3 narrowband spikes of constant activity in the 2.
Similar to other audio devices, microphones and guitars can create constant interference. When deploying a wireless network that coexists with live music, test all of the equipment to make sure the instruments do not cause interference to the WLAN. A time division duplex TDD transmitter shares a channel or a frequency range to communicate with other devices using the same channel.
This technology can look similar to Wi-Fi in the spectrum. A jamming transmitter creates constant noise across each frequency. These are used in a denial-of-service attack, and will prevent other wireless technologies from fully operating. Continuous transmissions with a narrow band. Some baby monitors can take a wide range of the 2. Video Baby Monitors can be problematic for residential Wi-Fi. Both are easy to use and show results for any wireless networks in your area.
For iPhone users, the Airport Utility App does require you to go into your device settings and turn on the Wi-Fi scanner. For Android users, Wi-Fi Analyzer is a step easier.
Open the app and look for the networks found. Each entry will list strength as dBm. Just unzip and double-click the EXE file. Hold the option key and click on the Wi-Fi symbol.
Either your walls are very thick and dense, or your router is old and unable to broadcast very far. If you have plaster walls, consider moving the router as close to the center of the home as possible.
If your router is older, it might be time to upgrade. When doing so, look for one that supports both 2. If you have a large home, you might want to consider a mesh router. They are an easy way to boost the Wi-Fi signal throughout your home and include other great features, like automatic firmware updates and guest networks. Heatmaps are a great way to determine where your wireless is strongest and weakest with an easy-to-understand visual. You create a sketch of the layout of your home, and then you walk around while the program measures the Wi-Fi strength.
It then colors in your map to give you a general idea of Wi-Fi signal strength throughout. However, if you try each of these methods, you can get the most accurate information to make an informed decision about what to do next. Use Google Fonts in Word.
