The Importance of Wi-Fi Connection Speed

Radio signals grow weaker as the distance between the transmitter and receiver increases. Meanwhile, the data rate for a given client will adjust dynamically depending on the distance and signal strength. As the distance between AP and client increase, the signal strength will decrease. As the signa...Read more

Differences Between TCP and UDP

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are the most common network protocols used in network device communication today.The connection-oriented TCP was developed first and is more common, as it guarantees delivery and accuracy of the data transmission. The protocol trac...Read more

PoE Defined and How to Avoid Common Issues

PoE “Power over Ethernet” has become a very common technology in today’s enterprise environments. As the demand for PoE increases, the demand for increased power goes up as well. The current standard of 802.3bt provides up to 71W. It’s important to validate that the expected Power is being supplied ...Read more

Documenting Your Wi-Fi Network Doesn't Have to be Painful

It’s true that Wi-Fi network documentation isn’t the most fun thing to do. In fact, it can be such an eye-rolling task that engineers in many organizations avoid it until necessary. In some cases, documentation is considered a low priority task – until a problem strikes. When troubleshooting a criti...Read more

Understand Noise with Wi-Fi SNR

SNR, or Signal to Noise Ratio, is a measurement of how strong a signal is through the noise of the medium it is traveling through. It is the ratio of Signal to Noise. For example, a Signal of -24dBm with a noise of -90dBm would yield a SNR of 66dB. SNR Connection Quality 10dB - 15dB Unreliable Conne...Read more

PING Usage and Limitations

Ask any network pro what kind of test they try first when taking on a trouble ticket… Inevitably, they’ll say, “I send a Ping.” But why use Ping?Ping is a protocol used to verify device availability, response time, and packet loss in a network by sending ICMP (Internet Control Messaging Protocol) Ec...Read more
