4.2.1.4 Network Platforms

Return to Platforms

A DIDO, by definition, is a collection of networked nodes. Traditionally, the network is assumed to be Ethernet with nodes connected over Local Area Network (LAN) and/or a Wide Area Network (WAN) using a Network Device.

The connections can either be:

• Wired Network using
  • Network Cabling
  • Universal Serial Bus (USB)
• Wireless Network using Wireless Fidelity (Wi-Fi)

Note: for Private, permissioned DIDOs, there may be explicit bans on wireless or even USB connections.

However, there is a lot of growth and development using other wireless connections other than Ethernet or USB. For example:

• Bluetooth
• ZigBee
• Near-Field-Communication (NFC)

Consequently, it is important to identify the kinds of connections that are required to support the DIDO. Some examples are:

• Many contactless payments systems use Radio Frequency Identification (RFID) and NFC
• Many supply chains use RFID
• Many smart home efforts use WiFi and zigbee
• Many automobiles use Bluetooth to connect phones, make queries, play music, etc.
