Major risks associated

• Major risks centered around network
• Network traffic
• How much bandwidth/users
• Latency
• Back and forth between base station
• Packet loss
• Impact on overlaying signals
• Interference
• Potential obstacles, etc.
• Seamlessness
• Packet transition between different nodes
• Hardware software usability

Risk Mitigation

• Fundamental Risks
• Must be able to seamlessly have a conversation
• Packet loss cannot be an issue
• Latency must be below .5 seconds
• Ancillary risks
• Nice to have 10 users
• No hardware issues
