Update README.md

> The purpose of the MEC Sandbox Macro Network City Scenario is to provide a MEC Sandbox user with an understanding of MEC Service API behavior in an urban setting:  MNO Network with 3GPP Points of Attachment (e.g. 4G & 5G) and WiFi hotspots.

## Macro Network Location Monaco

## Scenario Location

> The MEC Sandbox Macro Network is set in an interesting section of Monaco, where the following client or terminal types are expected:  Vehicles, Pedestrians and Fixed Wireless Infrastructure.

## Example MEC Sandbox Use Cases

## MEC Sandbox Use Cases

> This section provides different MEC Sandbox use cases

| Client | Use case

| Client type | Use case

| - | -

|External ME App |  [Discovering of the network & tracking a terminal location](https://forge.etsi.org/rep/stf-587/mec-sandbox-scenarios/tree/master/Macro-Network-Scenario/use-case1.md)

|Browser | [Tracking a terminal location](https://forge.etsi.org/rep/stf-587/mec-sandbox-scenarios/tree/master/Macro-Network-Scenario/use-case2.md)

## Assumptions and Miscellaneous

1. Network configuration is static:  

    * Number of access points, zones, etc.  

    * Service status is always on:  "Serviceable".

2. Sandbox uses local server time as a reference and does not correlate to Sandbox user time.

3. Sandbox UI will be designed & optimized for the Chrome desktop browser

  - Other browsers & mobile platform browsers are not guaranteed

## Assumptions and Limitations

| Category | Assumptions/Limitations

| - | -

|Network configuration|- network configuration is static<br>- Number of access points, zones, etc. does not change at execution time<br>- Service status is always:  "Available"

|Time|- sandbox uses local server time as a reference and does not correlate to user time

|UI | - UI is designed & optimized for Chrome desktop browser<br> - other browsers/platforms (including mobile) are not guaranteed
