WPA2: while not perfect, WPA2 is the most commonly used WiFi security protocol and security certification program today, and it includes an AES-based encryption mode as well as support for CCMP (Counter Mode Cipher Block Chaining Message Authentication Code Protocol).Available since 2003, WPA includes a Message Integrity Check, which is designed to prevent an attacker from altering and resending data packets, replacing the cyclic redundancy check (CRC) that was used by the WEP standard. WPA: Wi-Fi Protected Access is a security protocol and security certification program developed by the Wi-Fi Alliance as a replacement for WEP.

While there are still many networks that WEP, the security they provide couldn’t hold up to any serious hacking attempts. In 2004, WEP was declared deprecated by the IEEE due to its weak security.

WEP: ratified in 1997, WEP (Wired Equivalent Privacy) is a security algorithm for IEEE 802.11 wireless networks.

It extends the channel with to 160 MHz and adds more MIMO spatial streams (up to eight) and downlink multi-user MIMO (up to four clients).īesides latest 802.11 protocols, a good RF spectrum analyzer should also be able to check security settings and understand the three most commonly used WiFi security protocols, which are WEP, WPA, and WPA2.

802.11ac: developed from 2008 through 2013 and published in December 2013 in the IEEE Standards Association, 802.11ac has a multi-station throughput of at least 1 Gbit/s and single-link throughput of at least 500 Mbit/s.

802.11n doubles the channel width, from 20 MHz to 40 MHz, which results in slightly more than double the data rate over the congested 2.4 GHz band. 802.11n uses a wireless-networking standard that uses multiple antennas to increase data rates, MIMO (multiple-input and multiple-output).

802.11n: has a throughput of 600 Mbit/s using either the 2.4 or 5 GHz frequency band.

802.11g suffers from the same interference as 802.11b in the already crowded 2.4 GHz range. 802.11g hardware is fully backward compatible with the previous 802.11 specification, 802.11b.

802.11g: has a throughput of 54 Mbit/s using the 2.4 GHz band.

The following three are by far the most common: It should be able to pick up all signals on the 2.4 GHz and 5 GHz frequencies and identify all 802.11 networks.Ĩ02.11 technology is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area networks, and there are several different 802.11 protocols used by modern wireless routers and devices today. Which WiFi Spectrum Analyzer Should I Use?Ī good WiFi spectrum analyzer should meet certain criteria.

Fortunately, there are many excellent WiFi spectrum analyzer software solutions available today, and many of them, including NetSpot, are so easy to use that even home users without any IT training can use them to optimize their home networks and say goodbye to slowdowns and connection drops. Without WiFi spectrum analyzers, locating the exact source of interference would be unreasonably difficult.

That includes microwave ovens, Bluetooth devices, car alarms, CCTV wireless surveillance video cameras, and cordless phones. Because of the steep rise of mobile and IoT (Internet of Things), the WiFi frequency spectrum has never been more crowded.īut it’s not just WiFi networks themselves that cause interference and corrupt other WiFi signals, most common electronic devices can create interference and noise as well. Ideally, no two WiFi networks should run on the same channel, but this is seldom possible in practice. Each of these two frequency bands is divided into multiple channels, which provide a degree of separation of individual networks. WiFi networks are broadcasted either on the 2.4 or the 5 GHz frequency band. A WiFi spectrum analysis is typically performed to find interference that negatively impacts wireless performance and to eliminate it. A WiFi spectrum analysis is the process of measuring the WiFi signal in a certain area and determining its strength.
