Case study | Banking sector network infrastructure
ChallengeThe branch offices were equipped with structured cabling and PoE injectors, which were also used for IP telephones. The solution applied was physically separate from the production network and a separate Internet link was used. The system was configured by using multiple SSIDs to separate traffic types, while all users shared the same pre-shared key (PSK). Given the frequency of visits of banking service users to branch offices, it was concluded that the previous solution had not allowed simple management of the guests logging in to the network. On the other hand, the branch offices did not have a local Internet link, but they used a central one instead, being connected by a 10Mbps link.
SolutionMaidea offered equipment made by Aerohive Networks, a regional partner. An optimal number of wireless network access points was determined by creating a 3D simulation of wireless signal distribution, while the positions and number of wireless network access points were determined for the provision of acceptable signal strength and data transfer speed. The project was implemented in two phases. The first phase included Wi-Fi coverage of central locations and installation of management and control components, while the rest of the branch offices in Croatia were covered in the second phase.
Given that there is no single point of failure, which ensures smooth operation of access points, the staff can freely use the Internet network, while the traffic and clients are allocated within the 2.4 GHz and 5 GHz spectrum. Additionally, Aerohive was used to prioritize applications for the staff and guests.
Currently, each employee accesses the network upon authorization and authentication, while the guests and staff may connect to the Internet and use it within any of the branch offices. The management system enabled separate network connection for the guests and staff. Guests can easily sign in to a Wi-Fi network in a simple and controlled way. In addition to simple installation, security and firewall settings are easily managed.
