NETWORK PERFORMANCE Are you failing to plan or planning to fail? Paul Gowans: A properly optimised network delivers significant benefits to the subscriber as well as the CSP Mark Slinger: CSPs are enabling the prediction of potential issues before they occur Customers want fast and reliable services and CSPs want to give those to them but attempts to do so require they tweak the best they can from their existing network infrastructure, hence industry momentum for effective network planning and optimisation, writes Jonny Evans E xpectations are increasing and, as consumers look to big video technologies such as 4k and 8k, it’s clear network performance is still a foundational element of the communications service provider (CSP) proposition. However, while they have to support such demands, they are faced with continuing pressure on margins. “Operator margins are being squeezed, yet at the same time customers are demanding a better more connected service, and bandwidth is becoming scarce as more and more go online,” says Ravi Kumar Palepu, the global solutions head in the communications business unit at VirtusaPolaris. Research from Viavi Solutions has shown that 50% of mobile data is consumed by less than 1% of users and in less than 1% of the network area. Paul Gowans, the marketing manager for Location Intelligence & RAN Solutions at the company, explains: “Planning and optimising is about making sure you deliver the best coverage and capacity to your end subscribers. This includes understanding where cell sites should be positioned, power levels, cell neighbor relationships… and what happens if a site goes down.” Traditional performance metrics are expanding beyond old school tools such as loads, capacity and quality. They more include customer experience and use of virtualised networks to help handle peak demand. Some CSPs – Vodafone, for example – persuade customers to download apps that capture data about location, connectivity and call quality. “The complex mix of overlaying network technologies, from small cells to Wi-Fi, to GSM, UMTS and LTE, means that to truly understand how to plan and optimise for superior customer experience, technologies need to be able to ingest any data, regardless of format, size and granularity to enable an end-to-end view of the entire network, across all previously isolated network domains,” says Mark Slinger, the head of product at SysMech. The expanding network performance toolkit means CSPs must now monitor many variables, driving them to use ▲ 54 VANILLAPLUS MAGAZINE I SEPTEMBER / OCTOBER 2016
