Pollen Network Key Components

Key components of the Pollen network include:
Hummingbirds (UE): Devices used for communications (e.g., mobile phones) capable of connecting to Flowers (in the US, via the CBRS spectrum).
Bumblebees (UE): Pollen-designed devices that verify network coverage and report statistics back to the Pollen network via Flowers.
Honeybees (UE): Devices using an eSIM that can verify network coverage, report statistics back to the Pollen network, and also indicate where coverage is needed via "Pollen drops."
eNodeB: An eNodeB is an LTE radio that operates on the CBRS spectrum (3.55 - 3.70 GHz) to communicate with UE / mobile devices. The eNodeB is connected to a GPS receiver used to determine geographic positioning (a requirement of utilizing CBRS). The eNodeB is in turn connected to the AGW via a local ethernet connection. For 5G service, this device is called a gNodeB, which Pollen will support when 5G becomes available.
Access Gateway (“AGW”): The AGW is a small computer that is part of the Flower and runs a reduced instance of the Mobile Core. Unlike legacy mobile networks that run a fully centralized Mobile Core, Pollen runs services on a partially decentralized instance of the Mobile Core at the edge of the network. (Note: The introduction of the Greenhouse architecture eliminates the need for a local AGW. Once Greenhouse Flowers start shipping, the description of the Pollen infrastructure will be updated.)
Router / Internet Access Point: Flower owners need to provide internet connectivity to the Flower (in addition to electricity). The AGW connects via a local ethernet connection to the Router / Internet Access Point, which is in turn connected to the Flower owner’s Internet Service Provider.
​Internet Service Provider (“ISP”): A service provider the Flower owner contracts with to connect to the internet.
Internet Egress Point: The point at which data is delivered to / received from the open internet.
Internet Egress Privacy Service (“IEPS”): A Pollen-provided service that further encrypts communications and moves the Internet Egress Point from the ISP to the IEPS provider, preventing any actor from intercepting data or running network data analyses. Pollen will initially utilize the open source WireGuard service to provide the IEPS.
Mobile Core Orchestrator: The Orchestrator is a concept from Magma that facilitates subscriber management and communications with AGWs running on the edge of the network. Key functions performed by the Orchestrator include authenticating users (including mapping IMSI to NFT) and metering data usage, i.e., tracking Data Credits and authorizing users to transfer data if they possess enough Data Credits.
Payments and Rewards Engine: Where all data consumption and network verification log data are processed for purposes of making PCN payments to network participants (e.g., Incentive Payments, data haulage payments, etc.) Initially the engine will be centrally managed by the Mobile Core Administrator, but will be migrated to the blockchain in Phase II.
Identity Provider: The Identity Provider is the entity that produces the SIMs. We anticipate having multiple Identity Providers in order to avoid reliance on any single third party.
