Najboljše Wi-Fi analizatorjev za Windows: 5 Programske rešitve Pregledal

As Wi-Fi networks are getting more and more prevalent, it’s also getting more and more important to be able to monitor them. Given the invisible nature of the radio waves used in Wi-Fi, their monitoring certainly presents a new challenge to administrators tasked with managing them. Another important aspect of wireless networks is that while wired networks are constrained to their cabling domain, wireless ones are out there in the open. This means that your network is present at your neighbor’s and theirs is present in your premises. In order to keep a watchful eye on things, specialized tools must be used. This is why we’re bringing you this list of the five best Wi-Fi Analyzer software for Windows.

Before we reveal what the best Wi-Fi Analyzer tools for Windows are, we’ll take some time to briefly explain how wireless networks work. In order to better understand the features of Network analyzer software, it helps to be at least somewhat familiar with the terminology. We’ll also talk about Wi-Fi analyzers in general and introduce the different type of software you can find. As you’ll see, the term is loosely applied to very different tools. Potem, we’ll be able to jump into the core of the matter and give you a brief review of the five best Wi-Fi Analyzers for Windows.

Wireless Networks In A Nutshell

Wi-Fi was invented just over 20 years ago as a technology to allow computers–mostly portable and tablet ones–to connect to the Internet without the need for a physical connection. It made sense as mobility was a strong selling point of these devices but wired networks considerably reduced their mobility. Wi-Fi uses radio signals in the microwave range to transmit information between WiFi-enabled devices–which, danes, are not only computers–and a Wi-Fi access point. The term Wi-Fi was coined by a branding company and chosen because of its resemblance to the commonly used term “hi-fi”, with the “Wi” part standing for “wireless”. Contrary to popular belief, it was never a short for “wireless fidelity” just like Hi-Fi is a short for high fidelity.

Communications in a Wi-Fi network happen between a device with a wireless networking interface–a special type of LAN interface which uses radio signals instead of copper cabling–and a wireless access point which create a bridge between the Wireless domain and the cable domain. For devices from different vendors to be able to talk to each other, they all need to agree on how the data is transmitted. The Institute of Electrical and Electronics Engineers, or IEEE, is the governing body of the wireless network standards published as the IEEE 802.11 standards. These standards have evolved over the years from 802.11a to 802.11n with a handful of intermediate versions each providing some improvement–particularly in available bandwidth–over the previous version.

Technically speaking, Wi-Fi uses radio channels in the 2 GHz band. There are between 11 (USA and Canada) and 13 (Australia and Europe) overlapping channels in this band. Channels are often picked automatically by the access point and are chosen as to minimize possible interference with adjacent access points. This frequency band is susceptible to interference from microwave ovens, cordless telephones, and Bluetooth devices. More recently, a new 5 GHz has been used with 23 non-overlapping channels.

Apart from the wireless adapter in your portable device and access points, several other types of devices are commonly used in Wi-Fi networks. There are, na primer, Wi-Fi routers that combine the functionality of an Internet router, a Wi-Fi access point, and a firewall. Those are typically used on home, small office, or branch office networks. Another common device is the Wi-Fi bridge which simply bridges a wired network to a wireless one. They were once common in the gaming world back when consoles only had wired network interfaces.

What’s In A Wi-Fi Analyzer

Wi-Fi analyzer is a very generic term. Different vendors use it to describe totally different tools and concepts. They all share one thing, čeprav, and it is this shared characteristic that makes them Wi-Fi analyzers. What they all have in common is that they all provide some information about the network that is not readily available. Some are oriented on the radio side of the network and will mostly provide information on channel usage or radiated power while other instead are oriented on the data side of the network and will provide traffic information, much like any other network analyzer tool.

Different Types Of Tools

The first type of tool that we can call a Wi-Fi analyzer is a tool that will “listen” to the radio spectrum and provide tons of information on what it “hears”. It will give you a pretty clear picture of what Wi-Fi networks are present at your location, what frequency band and channel each uses as well as each channel’s radiated power. They are great tools to use before you actually start planning your Wi-Fi deployment. They tell you about potential areas where interference could pose a problem by detecting other WiFi networks in the area.

Another type of Wi-Fi analysis tool is called the heat map. pravzaprav, the heat map is not the tool but its end result. In a nutshell, a heat map is a physical map of an area–such as an office building floor plan–over which the location of each access point is indicated and that will show the radio radiating pattern of each access point. Its primary uses are in the planning phase of WiFI deployments to ensure that access points are located for the most uniform coverage or in the upgrade phase to identify weak spots where the addition of access points would be beneficial. Heat map tools are rarely stand alone and will often be integrated into other types of analysis software.

The last type of tools is bandwidth monitors. They are much like bandwidth monitor in the wired network domain. There are a few differences, čeprav. While wire networks typically use switch where each connected device uses one port and measuring bandwidth on that port will tell you how much bandwidth that device uses, Wireless networks don’t have one port per device that can be monitored. Often, Wi-Fi Bandwidth monitors will measure the bandwidth used by every connection to an access point without being able to tell them apart. Some network monitors that support wireless networks will be able to pull Wi-Fi-specific operational data from access points.
