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.
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. (more…)
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.
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 meets expected quality standards, the customer and carrier will use the metrics stated in the SLAs as parameters for measurement.
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 regulated by legal standards (set up by the USA, Europe, Japan, etc.) to guarantee interoperability between devices emitting waves and prevent interference with others. (more…)
