Non-IP Data Delivery (NIDD) offers efficient communication between IoT devices and enterprise applications. This data delivery method can help applications that transact small amounts of infrequent data. NIDD is capable of transporting up to 1500 bytes in a single transmission without the tens of bytes of overhead required by IP, and higher layer protocols such as TCP or UDP. NIDD helps to reduce management overhead by eliminating the need for maintaining pools of Static IP for devices.
To use the NIDD service on the Verizon LTE Network, devices must subscribe to Verizon’s NIDD APN, VZWSCEF. During the initial network attach process, the device attempts a Type Non-IP connection request. The device also indicates to the network that it supports CP CIoT Optimization. Verizon’s LTE network supports more than one simultaneous Packet Data Network (PDN) connection. The Verizon Network allows the device to establish and maintain connections with an IP PDN and Non-IP PDN simultaneously (only for devices that support this capability).
An enterprise application can use ThingSpace APIs to enable the NIDD service and to send or receive NIDD to/from an IoT Device.
NIDD is only supported for NB-IoT devices currently.
