The Commissioning Process: Steps and Considerations

Commissioning FlexiPacket Microwave equipment is a multi-stage operation that extends

beyond mere hardware installation. It encompasses physical setup, software provisioning,

performance optimization, and integration testing.

1. Pre-Installation Planning

Successful commissioning begins with comprehensive planning. This phase involves:

Site surveys to confirm line-of-sight and identify potential obstructions or

1.

interference.

Frequency coordination and spectrum licensing compliance.

2.

Link budget analysis to predict achievable throughput and stability.

3.

Preparation of installation tools and commissioning software.

4.

This meticulous groundwork is crucial to minimize downtime and avoid costly rework

during on-site activities.

Physical installation entails mounting antennas, installing radio units, and cabling. Precise

antenna alignment is paramount to maximize signal strength and link quality. NSN’s

FlexiPacket Microwave radios often include built-in tools such as spectrum analyzers and

signal level meters to facilitate this step.

Fine-tuning antenna azimuth and elevation angles during commissioning mitigates

multipath fading and interference, directly impacting throughput and latency.

3. Software Configuration and Network Integration

Once hardware is in place, configuring the system through Nokia’s Network Management

System is the next step. This involves:

Assigning IP addresses and configuring routing protocols, often OSPF or static

1.

routing.

Setting up service profiles tailored for LTE or 5G backhaul traffic.
