Laptops, smartphones and tablets equipped to run unified communications such as Microsoft Lync represent a significant opportunity to rightsize networks. With voice and video reliably delivered to mobile devices, IT departments can eliminate the need for traditional telecom equipment and networking ports – a few organisations are even considering getting rid of the desk phone altogether. But for this to happen, the Wi-Fi has to be reliable. Completely reliable. This presentation will address why ‘good enough’ sometimes just isn’t when it comes to UC. It will arm you with the knowledge you need to plan and design networks for the mobile employee that consumes, and generates, latency sensitive traffic.
