OUR SERVICES

Because we are dedicated to bring you quality work through survey and engineering to commissioning and integration. 

 
We are vendor neutral, so instead of pushing a particular platform, we will engineer a solution that best fits your needs.
— Mir Mahmud, Senior Design Engineer, 12 years with On Air Solutions

OUR PROCESS


Benchmark and Survey 

The first step to our DAS deployment process is survey and engineering. During our Benchmark signal measurement surveys, we simply collect the strength and quality of existing indoor signals. We use various tools, such as VIAVI or a phone, to receive the signals at any point of the floor and then plot that signal information, along with head-end room and equipment locations, onto the site floor plan. Furthermore, we will obtain the point of contact for the building, access information, equipment details, roof mount area and access details, electrical information, cable routes, and other key information. Data collected from these surveys are used to develop the engineering plan, design, and create a material list. 


Design

One of the most crucial phase to our process is the design phase. The design determines where the antennas and other electronics should be installed on a floor plan. Our team of design engineers use programs such as iBwave to produce these designs for DAS construction.  Additionally, our engineers also produce a logical diagram, which illustrates all elements needed for the DAS (from RF source to antenna), shows the length of coaxial and fiber cables, indicates input/output power levels, and labels of the antennas and electronics corresponding to the floor plan design. With these designs, our engineers can create a propagation plot which illustrates signal predictions in the form of a heat map. Construction ready documents from this phase are logical diagrams, floor plans with device locations, and bill of materials (BOM). 


Construction

Once we have our design and approval from our client, the next phase is the actual construction. This will involve the installation of coaxial and fiber cables, mounting electronics and antennas, making interconnections (installing jumpers, couplers, combiners, etc.), and running several tests (such as Sweep, PIM, ODTR, Optical Loss, and CW test). Once we have our design and approval from our client, the next phase is the actual construction.

Commissioning and Integration

Construction is followed by what we call Commissioning & Integration. This involves further testing of the DAS, uploading all RF parameters into the electronics, and then integration of signal sources into the DAS. Throughout this phase, optimization takes place so that we can extract the best performance of the DAS. This is the phase when we make the DAS operational and start carrying voice and data traffic.


Close-Out Package

Close-out package is, as the name indicates, a collection of all deliverables of the first 4 phases. It can be used as a guide during troubleshooting or maintenance activities. This is not necessarily a phase by itself, but it is so critical for a healthy maintenance of the DAS, that this can be considered as a separate phase.


Maintenance 

Finally, maintenance is the last phase. In this stage, we continuously maintain and monitor the DAS 24/7 and dispatch within the service level agreement (SLA). Additionally, we perform a quarterly health check to ensure optimal performance of the DAS.
