The document discusses how building a single infrastructure service across Kent and Medway, called the Kent Public Service Network (KPSN), can help facilitate collaboration. The KPSN provides connectivity to over 370,000 users across more than 1,160 sites for 27 partner organizations. It aims to help meet common goals like creating a personal health record for residents and mobilizing the workforce. Services provided over the KPSN include internet access, email, filtering, firewalls, and a common WiFi roaming service now available at 250 sites that allows staff to work flexibly across the public sector estate. The roaming service fosters collaboration between organizations by enabling connectivity and access to online systems at various locations.
