Abstract
There is an extensive expansion of fiber infrastructure for high-speed broadband networks in Sweden, and Landskrona municipality is one of the leading examples. Owing to the superior capabilities of a fiber based network, a number of digital welfare services can be provided directly to residents and companies of the municipality. Social care is an example of a welfare service that can utilize the superior capabilities of a fiber based network. Currently, the social care system in Landskrona Municipality experiences extremely long delays. Deploying GPRS as the primary transmission medium for the social care system is one of the causes for the extremely long delays. This report provides a thorough description of how the current social care system in Landskrona municipality can instead deploy fiber, to reduce the long delays experienced by the users of the service. Interestingly, performance evaluation of the results from this project show that there would be a significant reduction in the transmission network delay should GPRS be replaced with fiber.Most European Countries have developed and deployed social care systems, but these systems are under severe stress and under-performing. Part of the problem has been that, this field has not benefited from the technological advancements and innovations. Majority of the societies to-date deploy GPRS as the transmission medium to route alarms from the alarm units to the alarm receivers. Because GPRS has always been characterized by variable throughput and delays for packet transmissions, social care systems that use GPRS as the transmission medium always experience long transmission network delays. In a bid to solve this challenge, this project aimed to replace GPRS with fiber. This project developed a prototype that utilized the robust Internet connection of fiber, and a performance evaluation of the usage of GPRS and fiber networks for the social care service was established
