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:

using Network CablingUniversal 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:

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

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