Packet-switched Data Networking Unlike circuit-switched networks, a packet-switched network breaks the data stream into small packets, each of which can be sent across the network individually. Network access is guaranteed to be instantaneous, dependable and secured. Narrowband Mode - Bandwidth Efficiency The MANGO communication channels operate on a bandwidth of 12.5 kHz, meaning that it is a "narrowband radio technology", thus providing a highly efficient use of the bandwidth capable to transmit large volumes of short bursty data, for example, emails and trans- action information in a matter of seconds. Network Flexibility - Expandable Design for Future Growth and Development The flexible design of the network makes it highly scalable for future expansion. By simply adding more base stations, the growing number of mobile users can receive services easily. Open Platform - Catered for Customized Applications MANGO provides an open platform that caters for difference data communication applications. This platform is proven to provide solutions for emergency services, public safety, trans- portation services, logistics, banking, financial institutions, security companies, remote monitor and many others.
