SD-WAN deployment in a large bank
The bank, like all others in its sector nowadays, is facing a far-reaching technological and cultural transformation. The banking industry continues to advance swiftly towards a new ecosystem and prioritizes adapting to meet the needs of new “digital” customers. As a result, the customer has undertaken radical organizational and technological change to drive forward a renewal of corporate culture and speed up the transition from an “analog” bank to a knowledge-based service company of the digital age.
One of the most important keys the bank has identified for its digital transformation is that of modernizing its technological infrastructure. The digitalization process of this customer is a process keeping pace with technological advancements and therefore ongoing. In this case, the customer has undergone various phases of technological change related to Teldat.
SD-WAN for a pharmacy’s network
The pharmacy chain is experiencing rapid growth and development and anticipates its stores will increase in number from 1,030 to 1,500 this year alone. Given this expansion, our customer recognized the need to find new solutions to various problems.
The customer currently uses corporate Internet. Due to not having MPLS VPNs, the company found itself in an untenable situation, with constant signal intermittency or interruptions just being one of the many problems. Obviously without a reliable connection, vital services such as online virtual or onsite doctor consultations or even cell phone credir refills were unfeasible.
IP network protocols for Smart Grid
In recent years, the client has begun an ambitious initiative aimed at carrying out a technological transformation in the field of smart grids. This project resulted from a change in regulations requiring older electricity meters to be replaced with a new electronic device that enables hourly discrimination and remote management; that is, it provides the ability to read customer meters and change contract conditions without having to send someone to the customer’s site.
In order to meet these objectives, the client has developed an intensive plan to modernize 97.7% of its Spanish meter park and adapt almost all of its transformation centers by the end of 2018. With the Spanish electricity scenario in mind, this adaptation has been implemented in two phases. In the first phase, 80% of the company’s meters were replaced, with the focus on densely-populated areas where there was a greater concentration of meters.
Total connectivity for buses
This project is composed of two separate phases. Phase one, in 2010, consisted of installing 2,200 Teldat H1-Automotive devices on EMT buses. Phase two, a renewal phase implemented in 2017, involved the routers being replaced by their latest version, the Teldat H2-Automotive+.
Initially, the main objective was to make the bus network safer and more comfortable by installing a series of CCTV cameras (operated and managed from an Alarm Reception Center) throughout the bus fleet. To ensure a high resolution and real-time access to on-board camera footage from the Alarm Reception center, the buses required a reliable broadband connection.
On board connectivity for high speed trains
Teldat installed H2-Rail routers and APR222ac access points in coaches. The H2-Rail device is in charge of providing ground-to-traincommunication and onboard connectivity. It has been specifically designed for high-speed trains and has the necessary certifications (i.e. EN 50155) to fully operate in a wide-range of scenarios. Thanks to its rugged hardware design, it is fully protected against vibrations and can withstand extreme temperatures ranging from-25 ºC to 70 ºC. As a result, the device passed all standardization tests and met the project’s strict requirements. To improve access to the mobile network, H2-Rail routers are equipped with up to fourLTE modules. In this particular case, the device had an additional satellite link.
The Open Link Aggregation (OLA) functionality, developed by Teldat, was used to optimize and better combine the different WAN links available. This feature allows for the simultaneous use of WAN interfaces, meaning the available bandwidths in each link can be shared to improve the internal network’s quality of service.
Telco LTE/4G resilience & failover
The carrier used to have ISDN on 128kb or 64kb, as their standard resilience lines. However, as the size of the carrier’s main line moved to broadband ( from narrow ADSL to up to FTTH/Fiber) the amout of clients as well as data over failover lines have increased, ISDN as resilience was no longer viable.
Hence the carrier required a new failover system that would give their customers an adequate backup system. The carrier has decided that cellular would be the best type of failover system to offer their clients. However, various points had to be solved regarding their installed base of main line routers.
