CAREER EPISODE 1

BTS Swap from Alcatel Base Transmitter Station (BTS) to NOKIA Multi-Radio BTS

  1. Introduction

[CE 1.1]

Title: BTS Swap from Alcatel Base Transmitter Station (BTS) to NOKIA Multi-Radio BTS

Duration: [Date] – [Date]

Location: Nairobi, Kenya

Organization: Nokia Solutions and Networks

Position: Field Engineer

  1. Background

[CE 1.2] Kenya experienced a rapid growth in demand for data services that was fuelled by increased proliferation of smartphones; this triggered the UMTS 900 MHz spectrum upgrade which aimed at enhancing indoor coverage penetration and improved quality of data services for customers across the available networks. This prompted the upgrade by Airtel Kenya, of its network sites in major towns within the country, in partnership with the Nokia Networks.

[CE 1.3]The work was done for BTS swapping from Alcatel Base Transmitter Station (NS) to Nokia Multi-Radio BTS. I was the part of the project as the Company’s Field Technician in the South Rift, North Rift and Central regions of Kenya. My overall responsibility was to check installation quality and to ensure end to end transmission routing. I was also tasked with commissioning and integrating Nokia Multi Radio BTS after ensuring quality of service, and the decommissioning Alcatel BTS. The installation of Multi Radio System Modules (ESMB/C) and RF Modules. This included assembling the right tools e.g. 25 nanometer torque screw drivers, multi meters and properly mounting and grounding the modules

[CE 1.6] Responsibilities:

  • I worked on transmitter checking availability with the time slot allocation plans which confirmed the status of the process.
  • I did transmitter availability checking along with allocation of time slots which was followed with confirming the jumper connections, commissioning, connections and transmission settings.
  • I made SUMA utilization which provided BTS controlling and central management was done accordingly for carrying out digital transmission.
  • I conducted an analysis on the clock and timing generation which resulted in BTS internal digital interfacing.

CAREER EPISODE 2

Microwave Link Installation and Commissioning

  1. Introduction

[CE 2.1]

Project: Microwave Link Installation and Commissioning

Duration: [Date] – [Date]

Location: Nairobi, Kenya

Organization: Nokia Solutions and Networks

Position: Field Engineer

  1. Background

[CE 2.2] Microwave links are line-of-sight wireless communication technology equipment that makes use of high-frequency radio beam waves. This technology provides high-speed wireless connections for sending and receiving video, voice, and data information. Microwave links are popular for point-to-point communications as their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be directed at the receiving antenna in a direct line of sight, therefore, allowing nearby microwave equipment to use the similar frequencies without interfering with each other. Lower frequency radio waves are very prone to such interference. Additionally, the high frequency of this technology allows the microwave band a comparatively large information-carrying capacity; it has a bandwidth 30 times that of other radio spectrums below it.

[CE 2.3]The work aim was specifically based on carrying out the installation and commissioning of microwave links which was done with the constant expertise applied in the telecommunication engineering domain. All the related work objectives were accomplished using the telecommunication engineering expertise with a thorough discussion made with the project manager. 

[CE 2.6] Work responsibilities:

  • I worked on checking the lightning protection for the antenna system.
  • I applied the appropriate positioning of the cable ladder and it accessed to cabinets proper side for the co-axial feeder.
  • I made sure to ensure the antenna sealing which was fitted properly and polarization was executed accordingly using the telecommunication engineering skills.
  • I made partial and full site decommissioning services which worked with proactive maintenance activities.

CAREER EPISODE 3

Troubleshooting Restoration of Major Node

  1. Introduction

[CE 3.1]

Title: Troubleshooting Restoration of Major Node

Duration: [Date] – [Date]

Location: Nairobi, Kenya

Position: Field Engineer

  1. Background

[CE 3.2]The consideration is made on the mixed-integer programming model based on taking account restoration requirements analysis along with other hardware constraints. It works in abstracting from the specific failure and restoration protocol situation. This assisted in providing new structural insight into the network restoration issue and showing the mathematic viewpoint. Link Restoration, Reservation, and Path Restoration are the most common restoration techniques.

[CE 3.3] The work aim was executing the branch and cut framework for troubleshooting operation and restoration of a major node. I evaluated the algorithm process which included pricing problems based on computational complexity investigation. I executed the abstraction from the specific restoration protocol which turned out to be adequate from the computation viewpoint. Also, I carried out an investigation that indicated the global and local restoration rather than a path, link, reservation, and mixture restoration. 

[CE 3.6] Project Duties:

  • I applied telecommunication engineering skills for real-world network testing and the algorithm process was executed for computational complexity analysis mainly associated with restoration technique.
  • I did work results computation mainly based on optimal small networks cost execution and carrying out an analysis against single edge failures.
  • I did path restoration technique utilization in which the flow of NOS mainly rerouted from source to target.
  • I made link restoration technique implementation in which scheme was executed for local rerouting and it specified termed as span restoration.
