Narrowband IoT. Narrowband Internet of Things (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology standard developed by 3GPP to enable a wide range of cellular devices and services. NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density.
Common Mobile Radio System or traditional cellular networks consists of traffic from our SMS-enabled non-mobile carrier customers (AKA SMS-enabled OTT). We call these solution providers: NUVOs for Network Unaffiliated Virtual Operators as they provide mobile-operator like services such as voice and messaging and interwork with the legacy ecosystem. These are also called Cloud-based Messaging providers. These are primarily based in the United States. Key providers include: Twilio, Bandwidth, Nexmo (Vonage), Pinger, TextNow, and Google Voice.
Some SMSCs are able to provide a proof of delivery notification (similar to the concept of email COD), once the message has reached the subscriber’s handset. However, this does not mean the message is actually viewed; it has just arrived on the handset. Some Digital Interconnect customer’s use the notification feature (where available) to trigger their billing process and charge the subscriber for the service.
Number Resolution System – this is our global phone numbering database that is distributed to all our data centers and accessible to all of our messaging hubs. It utilizes data feeds from over 2 dozen authoritative sources around the world to populate the phone numbering information. One of the primary missions of NRS is to maintain up to date MNP (Mobile Number Portability) data in supported countries around the world.
The requirement set forth by federal legislation that allows consumers of mobile communication services to retain their mobile phone numbers for as long as they wish, even if/when they change mobile service providers. Legislation was passed to stop the requirements by carriers to change phone numbers each time the consumer switched carriers.
