Needs assessment

Needs assessment

Needs assessment of our customers is the first step of the consulting and design department of microwave links and telecommunications and radio equipment at Iran Microwave. In this stage, it is necessary, after a face-to-face assessment and completing the necessary checklists, based on the obtained data, to fully understand the needs of the customers. What operational processes are performed in this step

In the process of designing and implementing a microwave link, the first and most critical stage is accurate consultation and assessment of the customer’s needs

The consultation process for designing a microwave link includes stages that require careful consideration of customer needs and their alignment with existing technical conditions

At this stage, the consultant must accurately analyze the type of link application, the required bandwidth, and sensitivity to delay.

Microwave application type

The first question asked in the consultation session is: What is your purpose for setting up a microwave link? The application of the link will determine the design path, equipment selection, and link settings

Common applications of microwave links include

 

Bandwidth Requirement

Delay Sensitivity

Explanations

Application Type

HighMediumConnecting to the global or internal networkInternet (Data)
Medium to HighMediumConnecting different offices of a company or organizationCorporate Data Transfer
Medium to High (depending on image quality)LowSending images from surveillance cameras Video Monitoring
Low to MediumVery HighTransferring voice calls over the networkVoIP (Internet Telephony)
LowLowSending data from sensors and PLCsIndustrial Data Transfer

The required bandwidth

After determining the type of application, the next step is to calculate the required bandwidth. This factor determines what type of equipment and what level of frequency permissions should be obtained

For example

  • For VoIP with 50 simultaneous users, approximately 1 to 2 Mbps is sufficient

  • For monitoring 10 HD cameras, the required bandwidth is about 20 Mbps

  • For connecting organizational offices with a high volume of file exchange, up to 100 Mbps or more may be required

In consulting, this section is examined with questions such as the following

  • How many users do you have

  • What is the type of internet usage  

  • Do you transfer large files

  • In what quality do the cameras record

Operating Time

The operating time of a microwave link should be determined based on the customer’s needs and technical conditions. Some links may be used temporarily and for a short period, while others may be designed for a longer period and with the need for permanent support

Operating TimeConsulting Recommendation
Less than 6 monthsUse of lightweight and rental equipment
۶ months to 2 yearsPurchase of mid-range equipment with portability
More than 2 yearsLong-term design with stable and reserved equipment

In consulting, this section helps to determine

  • Should the equipment be portable

  • How much initial investment is reasonable

  • Is there a need to design with the possibility of future upgrades

Examining Origin and Destination Points

One of the completely technical sections in consulting is examining the geographical and environmental status of the origin and destination points. This examination includes the following

  • Geographic coordinates (via GPS or map)
  • Equipment elevation from the ground level
  • Presence of obstacles like buildings, mountains, trees
  • Straight line distance between the two points
  • Direct visibility (LOS – Line of Sight)

Without a thorough examination of these items, it’s impossible to correctly design the link. For example

If direct visibility doesn’t exist between two points, a repeater or path change is needed.

If the distance is long (more than 30 kilometers), equipment with higher power should be used.

 

Tools used in this stage

  • Google Earth  specialized RF Planning software

  • Topographic maps
