An ultra-narrowband (UNB) network is a

"As these technologies mature, the possibility for cheaply fitting sensing devices with such uplinks for telemetry can become more feasible. Research should focus specifically on the following domains:
- Portability. Wireless transmissions are affected by movement, in part due to Doppler effects, so efforts to properly categorize and accommodate mobility models of both end devices and base stations (possibly portable) . . . should be considered.
- Reliable transmissions. Current UNB technologies do not support duplex communications, so reliable transmission of data cannot be guaranteed, but it can be improved through techniques like retransmission across multiple channels.
- Device management. Due to the low-power and uplink-only nature of current devices, monitoring, management, and maintenance should be considered priorities for possible deployments.
