APPENDIX I

Engineering Support Services

Sales Engineering Support

• Preliminary System Design: Configuration of the anticipated system

using pre-survey data. Terrain characteristics will be based on pre-survey

assumptions and may vary with survey data. This is usually to come upwith a budgetary quote. It involves marking of the sites on the map by

distinctive colours , insertion of information on existing infrastructure and

drawing of path profiles.

• Tenders : Response to bids and tenders as advertised. Analysis of the

client requirement and provision of a detailed or summarized price quote

that meets the tender requirements. This also includes preparation of equipment compliance statements against tender specifications

• Proposal - Engineering solution: Encompasses provision of the bestengineering technology to meets the client 's needs. Appropriate products

(index v) will be used for specified proposals. This task may come in as

system expansion requests or proposal from/to customer after a sales visit,

inquiry or exhibition

• Systems Integration-Involves report making for the given engineering

solution and evaluation of the design. This may involve other products for interfacing with in order to achieve optimum operation.

Field Surveys :This involves visiting of the site.

Pre survey assumptions are confirmed. Existing structures are checked to see if

they can accommodate new items. Distances required are measured.Existingequipments and their status are confirmed. Terrain data is checked to give a final

analysis. Access conditions are checked as well as power requirement details.

Final System Engineering Design

•

System Configuration: A survey is done to finalise on the best way toserve or link areas that the client desires to have services. This is usuallyillustrated as a system or network layout. System re-design is possible

after the survey.

• Link Calculations : This entails engineering path analysis, designing the

system operation parameters and configuration of the engineering



solution. Link reliability, signal levels and annual system availability is

calculated.

• Frequency Planning : Where the solution needs frequency allocation, a

frequency plan is done following the frequency allocation criteria for the

equipment. Link frequencies are assigned keeping in mind the existingfrequencies. Interference analysis is done. There are ITU-T standards and

Telecoms sector Policy and Regulations that govern this exercise.

• Equipment and Bill of Materials Specifications: After the system

configuration, a list of the equipment to be used is made. Where the

equipment is modular, the list will be detailed to the component or cardlevel and may comprise, antennas, towers, radio types,cable, routers,

servers, installation materials etc.

•

Engineering Reports : It includes a report on the survey data gathered, asummary of the equipment and recommendations, the design

specifications and parameters,

• Validation of Project Summaries: A project summary is basically a

priced list of the bill of materials that should include what is specified in

the bill of materials. Basel station profile is contained in projectsummaries. Validation therefore is a comparison between what is quoted

in the bill of materials against the project summary to ensure that the

correct type and quantity of materials is ordered.

System re-design and Frequency re-planning:

Depending on the survey information and implementation requirements systems

may be re-designed. Issues like change of policy by the frequency allocation

commission, existence of unforeseen systems with interfering signals before project completion and installation of other systems before project

commencement,and existing frequencies may necessitate a change in the channel

allocation or signal polarization.

After Sales Engineering Support – Resolution of:

• Propagation problems : This may arise due to change in path conditions.The climatic factors are analyzed in details and corrective measures are

undertaken to correct the propagation problems. This may involves

variation of antenna heights/type and clearing of isolated obstacles.

• Frequency interference : Interference may arise due to new systems

introduced in an existing system or when reflective interfaces are

introduced on/near the path. Change in signal polarization or change of



antenna heights may be as follows. Where filter sensitivity can be altered

then they can be adjusted to make the system more selective.

Interference is possible when combination frequencies of the wanted and

unwanted signal components can be transferred into the baseband of the

unwanted signal

• System Design problems: Include over design or under design of the

systems.

Training

1. Training for SRK Staff

To fully support the products and services in the region, SRKensure the following

training to its Engineering staff:

• Survey and Engineering (Abroad and Nairobi) : Training the

engineering team in survey techniques, safety in survey, engineering

system design techniques, system costing and ordering and basic systeminstallation procedures to help in survey and design.

• Project Management (Abroad and Nairobi) : This will entail project

evaluation and monitoring techniques, project resource and cost

management, project appraisal, worker appraisal etc.

• Product Training (Abroad and Nairobi) : Training on various productsin the market, their short comings and various modifications.

• Basic training : General understanding of the products, both current and targeted future products. Training on people so as

to be able to conduct exhibitions and sales whenever possible.

• Detailed training (Factory) : Understanding of system on

modular level and if necessary up to component level. Requires

attachment to various sections of the supplier production line .

• Refresher training: Continuous training for the staff

previously trained especially on new equipment or after long

periods of not working on the equipment. Field experiences can beexplained also during these refresher courses.

• Installation and Commissioning : Principles of installation andcommissioning of the products.

• Trouble Shooting : Detailed system trouble shooting techniques for the

Technical staff and basic ones for the engineering staff and management.Repair and recovery techniques be taught. Use of technical instruments

and reference to technical Manuals to be emphasized. Training on repairs

to be at the suppliers training centre and exposure of SRK staff tosuppliers repair centre necessary to enhance skills.

2. Local Training



Comtec Training Services Limited (CTSL) ensures local training to both SRK

Staff and the clients.This includes

• Product based training

• Other courses as per request



APPENDIX IV

Quality Control

Procedures and setting of standards for activities:

• Engineering Services :

• Pre-survey: Getting the subscriber locations, designing asystem that is cost effective and meets the needs, having a

thorough path analysis done from the office. Critical points must

be well documented.

• Meeting customer specifications/requirements/goals:

Design to take care of clients performance criteria e.g. fademargins, availability levels etc. Where choice of site has power,

subscriber location, security and Line of sight consideration, the

client goals must be met first.

• Field Survey Data Gathering: The right survey

equipment/tools-this may need to be updated with time, ensuring

safety procedures, confirmation of all critical points on paths, photos capturing all the important information including critical

conditions, detailed survey report and diagrams.The type of

information to be collected/gathered need be standardized anddocumented.

• Field Survey Report Making : Databases are created and

spreadsheets made from them. The report shows position for equipment and antenna system, documenting the site access,

highlighting the orientations of antenna system. This should be aguidance for the installation and commissioning teams as to what

to expect in performance and installation materials. Therefore the

report need to be tailored to convey useful information to thecustomer and system installations.

• Presentation of Report: The survey and engineeringteams need to agree on the best way to present the information the

reports. A synopsis of the report that gives summary explanation of

what is contained in the report need be included at the beginning of the reports. During presentation a guided tour of the report for theCustomer is encouraged. Good Cover page design to reflect the

customer and product vendor is good practice.
