Bulgaria, situated in Southeast Europe, is characterised by diverse geography from mountainous terrains in the southwest to the lowlands and plains in the northeast, which can pose some challenges for the distribution of technologies and telecommunications infrastructure across the country. With a population of around seven million, Bulgaria's significant urban centres include Sofia, Plovdiv, and Varna. Connection speed and internet accessibility are notably high in these concentrated urban spaces but less so in remote and rural regions. Recognising this, the Bulgarian government has implemented the "Digital Bulgaria 2025" strategy aiming to enhance digital connectivity across the country, focusing on improving broadband speed and coverage in rural areas. Innovations in technology, like the deployment of 5G networks, are also a key focus, with Sofia becoming a prototype smart city. Also evident is the country's commitment to renewable energy, exemplified by the Kaliakra Wind Farm and the growing solar power industry. Despite these advancements, Bulgaria still faces challenges to ensure an even spread of digital opportunities across all regions.
