Best Practice Networking
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.
Fibre to the Home (FTTH) is quickly becoming the norm for internet users around the world. When experiencing its capabilities first hand, there’s no question as to why. Achieving low latency with high throughput over long distances, coupled with the GPON (Gigabit Passive Optical Networks) format, makes FTTH a fantastic solution for deployments regardless of the scale. Ubiquiti has created a category of products 'UFiber' specifically suited for these type of installations. Here are some reasons why we believe you should consider UFiber for your FTTH deployments.
UniFi has become an exceedingly popular choice for small to medium (and even large) enterprise deployments. Although these units are 'plug-and-play', for the most part, it doesn't guarantee that they are automatically configured to function optimally for their environment. If you are using UniFi and have felt that it should be performing better, take a look at these tips which will assist you in optimising each of your installations.
PoE (or Power over Ethernet) is the method of transmitting both power and data across the internal cores of an Ethernet cable and is ideal for getting power to hard-to-reach areas. There are many variants available and the type of PoE you use is ultimately decided by your equipment's capabilities.
One of the biggest challenges with indoor wireless installations is ensuring you have sufficient coverage - meaning no dead zones and good quality connections in all the necessary areas. While indoor wireless connections offer simple installation and very few cables, they are unpredictable and easily affected by numerous external factors such as walls (obstructions) and interference from other wireless devices. Thankfully, there are a few products available to users to easily extend existing coverage when it does not live up to your expectations.
One of the most frequent problems we find in the wireless industry is poor link performance with the blame cast toward the hardware. Occasionally, this is out of the user's control, as the laws of physics dictate what is possible in each environment. However, there are various tools available at our disposal to ensure we make the most of the hardware. Here are 5 simple ways you can improve your Ubiquiti wireless links.
South Africa’s fibre footprint has several offerings at varying price points and service levels. Understanding how these solutions differ is highly beneficial when having to decide on the best solution for you or your customer’s specific requirement. There are predominately two different fibre technologies being deployed to satisfy local customer needs.
Fibre can be a complex task when just getting started as there are many different standards available in the market. This article intends to explain some of the fundamentals of cable and connectors to aid you with choosing the right components and solutions for your fibre deployments. Cable - The first decision you will need to make is your choice of cable. There are many different materials available to protect the sensitive fibre inside the sheath. Your choice will depend on whether you install indoors, outdoors, underground, aerial or underwater, each of these applications will require different types of cable composition.
Before setting up, mounting or configuring any wireless links, there are a few questions that you need to ask yourself before going ahead with the installation. Am I doing a PTP (point to point) or PTMP (Point to multi-point) link? Do I have clear line of sight to the other end/s? What equipment do I need to use? Answering these questions will help you plan your links to get the most out of your deployments. PTP or PTMP? This may seem like a trivial question but it is quite important. Depending on your answer to this question, all of the other questions will follow suit and be adapted to work for the answer. Must I cover a large number of connections coming back to a single point, or will there be individual links consisting of just two devices per link? PTMP topologies will generally achieve less bandwidth due to shared access to the wireless network.
ESD is a build up of electrically charged particles that can wreak havoc with your devices if not adequately protected. Lightning storms are a prime example of ESD build up. Turbulence in storm clouds causes a build-up of electrical charges that ultimately result in a lightning strike. Even when there is no visible lightning, friction caused by small particles colliding with the device creates a static build up which eventually defuses onto the electronics. If powerful enough, this discharge can travel through the PCB of the device, out the Ethernet port and down the Ethernet cable to the devices below.
