The Challenge

NEC Group had two separate network components that underpinned and supported both corporate and exhibition communication needs. However, the legacy network technology and inefficient design did not enable the business strategy that NEC Group needed to implement.

-Equipment used in the network that provided connectivity for exhibitors in the halls during trade shows had reached end of life. Similarly, major elements of the corporate network were unsupported with lack of spares becoming a critical issue.

-Not only were the two major networks managed by different teams, the implementation had become inefficient with some 1700 separate VLANS terminating on their Firewall Cluster. The Firewall Cluster could not be upgraded due to resident, bespoke software.

-Although the Firewall provided security, it was also being used to allocate dedicated bandwidth to exhibitors resulting in inefficiently high ‘traffic tariffs’ that were costly to run.

-The analogue CCTV system could not take advantage of latest video security technologies and managing traffic flows to best use the parking resources was a manual process, as was paying for car parking.

-Finally, the legacy systems weren’t WEEE compliant, which meant that NEC Group's management team could not meet their green targets.

The Solution

Through a phased project, GCI designed and implemented a number of innovative solutions that use a common core platform and a single LAN environment, underpinned by an ‘any service at any place’ concept.

NEC were provided with a technology enabling 10Gbps ‘resilient ring’ backbone network, which supports three functional areas as VLANs: Exhibitions, Corporate and Hybrid.

-GCI have reduced the number of VLANs by 94% to a manageable 100 and have assigned the bandwidth allocation task to the switches, allowing the Firewall to concentrate on what it is designed for; prevention of DOS attacks and other Unified Threat Management functions.

-New edge switches that have been deployed in the exhibition halls are now delivering future-proofed Gigabit Ethernet to exhibition stands, providing exhibitors with high speed internet access as well as access to their corporate VPNs and secure credit card payment services.

The 10Gbps core is very much an enabling platform that provides the basis of solutions for other problematic areas.

-The old analogue CCTV cameras have been replaced with pinsharp digital HD cameras both internally and externally.

-Externally, these wireless cameras can take advantage of the latest video technology and support ANPR (Automatic Number Plate Recognition) that has a security element, enabling NEC to automatically register visitors that have prepaid for parking.

-As part of a Vehicle Management System, ‘Loop counters’ have been deployed which are also wirelessly connected back to the network core so that car park management is automatic and when a given parking lot is full, traffic can automatically be signposted to park elsewhere.

Finally, all of this is managed by a newly created Venue Operations Centre that provides centralised management and support services for the entire venue.


The CEO… has been able to support the strategy for The NEC’s 'Destination NEC' project, which is to become recognised as the venue where people come to discover the future. The NEC’s £40 million Venue Improvement Program showcases a brand new look and feel but goes much deeper with a 21st Century enabling infrastructure.

The Financial team… has seen cost and efficiency savings with the removal of network bottlenecks and manual operations. The new infrastructure provides a platform on which new revenue generating services are being added.

The Technical and IT team… have delivered a leading edge network that supports the business strategy and solves operational issues. They have safe guarded the future of the communications infrastructure and created a service enabling platform for future revenue generation.

The End Users… and show delegates enjoy the benefits of high speed WAN access, whether to the internet or corporate VPNs and event delegates experience a better service from exhibitors, whether that’s a demonstration of cloud-based applications or simple credit card payments for product purchases.
