Nowadays, all companies provide their customers with Wi-Fi in some form or another. We find it in shopping malls, airports, restaurants, offices and even on transport. It is fair to say that Wi-Fi has become a commodity. Most customers want to connect to Wi-Fi services in the simplest way possible. Therefore, their preferred methods of accessing them might be an open Wi-Fi network or a password...
Nowadays, devices that are operated remotely (i.e., without local staff to verify their working conditions or act in the event of an incident) offer many services to the public.Some examples are: remote ATMs, billboards, ticket vending machines, etc. Generally speaking, companies that offer this kind of services have centralized monitoring mechanisms that ensure their smooth operation and allow...
Today, software-defined network technologies (SDN) can be applied to many more situations than initially thought (i.e., data processing centers) and are being used in the field of WAN to bring, over and above virtualization, resource optimization, flexibility and dynamism to the connectivity services for customers. This new technology, known as SD-WAN, allows the user to get rid of access...
How can we establish reliable measures for assessing service quality? An innovative QoS solution. One of the biggest headaches for a company’s network managers is verifying that contracted service levels are being met for their infrastructure. Carrier services usually include a series of contractual points which are summarized in service level agreements (SLAs). To determine whether a service...
We are surrounded by waves: radar, radio, mobile telephone, Wi-Fi etc., all occupying an established man-made order and based on invisible highways known as frequency bands. Wi-Fi technology, on the whole, uses 2.4 and 5 GHz bands, a small part of the electromagnetic spectrum divided into a series of channels, over which information flows (like traffic on a freeway). Channel distribution is...
Customer branch offices frequently find themselves with limited resources for WAN connectivity, this being a common problem associated to communications. WAN optimization under these circumstances makes sense, as the rise in productivity results in improved end customer perception. Through different techniques, optimization reduces both infrastructure and bandwidth costs, allows for centralized...
