Traffic filtering is a method of identifying and prioritizing different traffic types passing through a common router by applying filter rules based on your network requirements. When using MikroTik RouterOS, there are several ways to achieve this. One of the most common techniques is to apply traffic limitations by making use of IP Address Lists. Traffic can either be filtered by source, or destination IP addresses. If you want to filter specific users on your LAN, this can be achieved by using source addresses. Anything leaving the LAN (Internet) will be classified with destination addresses. A combination of these and other settings can also be used to achieve more specific results, but it all depends on your requirements.
Ubiquiti's Trivial File Transfer Protocol (TFTP) recovery method is the process followed to recover firmware on Ubiquiti devices. This method is useful when there is an unstable device connection or when the device cannot be accessed. These difficulties are typically due to some form of firmware corruption. Firmware corruption can occur due to a number of reasons, but the most common is by Electro-Static Discharge (ESD), and ESD is mainly caused by using unshielded cable and connectors. Fortunately, Ubiquiti's TFTP recovery method allows the recovery of firmware on most Ubiquiti devices. In this article, we explain how to perform this recovery.
When using a Switch or Power Sourcing Equipment (PSE), the PSE needs to meet the power requirements of Powered Devices (PDs). Examples of PDs include IP surveillance cameras, Voice over IP (VoIP), and Wireless Access Points (WAPs). All PSEs have a PoE Budget - This is the total amount of power PSEs can supply to PDs at one time, measured in watts. In this article, we will explain why the budget is often over-estimated.
Mesh solutions are available in various forms with all of them promising premium performance. Much like anything else, not all mesh solutions are created equal. Some offer exceptional performance for its price, while others are worth every penny for its premium user experience. In this article, we provide an overview to some of our mesh products and their speed test results.
South Africa's security industry has shown a rapid increase in demand for Video Surveillance Systems for business and homeowners. With a large variety of product offerings at different price points, understanding product functionalities will help you decide on the best solution. This article highlights the benefits of the UniFi Protect range and why it should be considered for video surveillance.
In a year characterised by unprecedented disruption for societies throughout the world, a similar transformation is taking place at the University of Pretoria. The launch of the new Engineering 4.0 facilities at the beginning of 2020 marks the start of “Sustainable, Optimised, Smart, Equitable transportation networks, supporting social & economic development in a disruptive & evolutionary society”.
MikroTik's Gigabit Passive Ethernet Network (GPEN) products are designed as a cost-effective alternative to fibre's Gigabit Passive Optical Network (GPON) solution. The key difference between these two technologies is that MikroTik's GPEN utilises copper Ethernet cabling instead of fibre. MikroTik has introduced a clever concept. Copper Ethernet runs of up to 1.5km makes this an ideal alternative to complex FTTX installations. Here are some of the benefits when choosing GPEN over GPON.
During the course of last week, there were a few reports globally of a security flaw in some of Tenda's Routers, specifically the following models: AC6, AC10, AC10U, AC15, AC18. In response, Tenda has released new firmware to patch this vulnerability across affected routers which is available on their website tendacn.com/en or via 'Over the Air' (OTA).
There is an extensive amount of high-sites and masts on buildings these days. With the ever-increasing number of radios placed on each of these high-sites and masts, it's interesting how few of them are in fact horn antennas. So, what exactly is a horn antenna and how would it make a difference?
With the 5GHz spectrum getting even more congested each passing day, the 60GHz options for high speed, short-range connections are becoming very popular in urban areas. This is where the GigaBeam works its magic. Using 60GHz, the GigaBeam (17dBi) is rated to provide near Gbps speeds up to around 300m. Thereafter it becomes more difficult to predict exact performance due to the nature of the 60GHz band. There is also a backup 5GHz 802.11ac radio for redundancy if the 60GHz band is affected by the weather.
