> The MEC Sandbox includes four Macro Network Topology options, including: 1) 4G Cellular, 2) 4G Cellular with WiFi Hotspots, 3) 5G Cellular, and 4) 5G Cellular with WiFi.
The following applies across all the Sandbox Macro Network Scenarios options:
* Network provided by a single Mobile Network Operator (MNO). Sandbox will appear as a "test" network and not an actual MNO network (e.g. Monaco Telecom)
* PLNM: MCC = 001; MNC == 001
* WiFi Hotspots are also provided by the MNO as 3GPP Trusted WiFi
* Terminals maintain a consistent IP Address across 3GPP cellular and WiFi connections.
* Terminals have a single data connection at any one time. Terminals attach to the closest Point of Attachment with the following order of connection precedence:
1. First connection preference is WiFi
2. Second connection preference is a 3GPP Small Cell
3. Last connection preference is a 3GPP Macro Cell, with no gaps in macro cell coverage.
* Final geo-location of access points (3GPP and WiFi) will be adjusted based on selected mobility paths of terminals.
* Terminals are identified by IPv4 Address, which is a common identifier across MEC Service APIs: Location Service, RNIS, and WLAN API.
### Macro Network 4G
* Seven 4G Macro Cell Tower Locations, as shown in the diagram below
* Each macro tower includes a single cell
* Macro tower range = 400 meters
* Terminals connect to the closest Macro Cell with some hysteresis
> Specific terminal mobility paths will be determined during scenario implementation.
## Macro Network User Configuration Options
> When selecting this scenario, a Sandbox User has options to configure the following:
1. Network Configuration: 4G vs 5G; option to include WiFi hotspots (needed for WLAN API)
2. Types and number of terminals
1. Network Configuration: 4G vs 5G; option to include WiFi hotspots (needed for WLAN API) - using the topologies in [Macro Network Topology Options:](#macro-network-topology-options)
2. Type and number of terminals
See details below.
