29 C H A P T E R 3 An underlying assumption commonly held is that the interests of the airport management, the network operator, and airport stakeholders are the same, but there is little validity to this assumption. For example, perhaps both the airport authority and network operator might benefit from a network technology upgrade, but doing the upgrade might create a cash flow problem for the operator or significantly impact their profits for the quarter.

Airports and Network Operators: Issues and Solutions 31 is very general and misses a number of issues. In the IEEE 802.11 standards, there are a number of options that manufacturers have flexibility to include or leave out of their equipment.

32 A Guidebook for Mitigating Disruptive WiFi Interference at Airports Irregular Operations Support Service level agreements can and should address the particular service level and performance requirements needed to sustain irregular operations or, specifically, emergency operations. The networks can be designed to provide priority message service or dedicated channels for critical airport operations such as security.

34 A Guidebook for Mitigating Disruptive WiFi Interference at Airports Revenue Sharing If revenue sharing is applicable, then it can also be addressed in the SLA or part of a larger contract. Revenue sharing is still in its infancy and there is not a clear path forward.

Airports and Network Operators: Issues and Solutions 35 System Performance Oversight Evaluating system performance in essence involves ascertaining whether the right level and amount of resources are in place to support wireless services, and then evaluating whether those resources are being used effectively to deliver an appropriate level of service. (As stated earlier, airport managers can define appropriate level of service by implementing an SLA with the network provider and stakeholders.)

36 A Guidebook for Mitigating Disruptive WiFi Interference at Airports Two-Vendor Model Among the case study airports, several observed that their relationship with their network manager was changing and they were being required to be more hands-on than was previously true. In several cases, a two-vendor model was being implemented.

Airports and Network Operators: Issues and Solutions 37 In a closed network, network managers have direct control over all devices on their network. However, in a "bring your own device" network such as exists at an airport, those controls are minimized or absent altogether.

38 A Guidebook for Mitigating Disruptive WiFi Interference at Airports devices and objects to be continuously connected to the Internet.10 The purposes behind these connections vary, but often the reason is to better extract and analyze data in real time. There were several pre-requisites for IoT that needed to be developed in order for it to become a reality.
