The revitalisation and digital transformation of legacy ‘narrowband’ UHF radio is changing perspectives with the advantages of existing frequency re-use and scalability. Additional capacity and IP connectivity is important to both water and electric utilities, and understanding digital radio characteristics is vital when implementing network upgrades. Even with modern high-capacity digital narrowband UHF networks now delivering 100 to 200 Kbps, filtering techniques must be considered when embracing new IP-based networks. See how simple approaches can transform network operation through example utility case studies.
