Why this programme exists
Every network, every camera system and every mobile call rests on physics that most IT training skips entirely. When a link fails, the person who understands signal loss, impedance and link budget finds the cause; the person who only knows software restarts the router and hopes.
This programme teaches the physical layer properly, in Tanzanian context: the operators and frequencies actually in use, the fibre plant actually deployed here, and the calculations an engineer is expected to do without a computer.

What you will be able to do
- Apply Ohm's law and power calculations to series and parallel circuits without a calculator app.
- Use a multimeter correctly for voltage, current and resistance — including knowing when to break the circuit and when not to.
- Identify and test capacitors, diodes, rectifiers and Zener references, and explain what each does in a power supply.
- Convert between decimal, binary and hexadecimal, and reason about logic gates and De Morgan's theorem.
- Program a microcontroller for a basic control task.
- Calculate wavelength, and explain amplitude and frequency modulation and their bandwidth cost.
- Work in decibels and dBm, and compute a point-to-point link budget that predicts whether a link will work.
- Select an antenna type for a job and explain the gain figure on its datasheet.
- Describe how GSM, UMTS, LTE and 5G differ, and which suits which part of Tanzanian geography.
- Explain total internal reflection, attenuation and the fusion splicing procedure, and read an OTDR trace.
Who should attend
- Electronics and telecommunications technicians
- ISP and mobile operator field staff
- CCTV and security systems installers wanting the underlying theory
- Technical college graduates needing practical grounding
- Anyone moving into fibre or RF work
Entry requirements. Comfort with secondary-school mathematics — the programme uses arithmetic, powers and logarithms, all revised where needed. No prior electronics experience is required.
How the programme is taught
Roughly a third instruction, the rest measurement and calculation on the bench. Circuits are built and measured rather than only drawn, and every formula introduced is then used on a real reading.
The RF and cellular material is taught against the networks operating in Tanzania, and the fibre material against the plant and equipment actually deployed here.
Module by module
Module 1 · Weeks 1–2 · 12 hours
Electronics Fundamentals
Circuits, components and instruments. The base everything else is built on.
- Ohm's law, power, and series and parallel networks worked through with real values
- Capacitors in DC and AC, reactance, and their role in filtering, coupling and timing
- Diodes: forward voltage, bridge rectifiers and Zener references
- Multimeter technique for voltage, current and resistance — and the mistakes that destroy a meter
Module 2 · Week 3 · 8 hours
Digital Electronics
How the analogue world becomes numbers, and what those numbers are stored in.
- Binary and hexadecimal conversion, worked both directions
- Logic gates and truth tables; De Morgan's theorem
- D flip-flops, registers and counters — and why eight of them make a byte
- Microcontrollers: an Arduino from first upload to a working control loop
Module 3 · Week 4 · 8 hours
Signals and Modulation
How information is carried on a wave, and what each method costs in bandwidth.
- Amplitude, frequency, phase and wavelength — and calculating each
- AM and FM, their bandwidth, and why FM survives noise better
- Digital modulation across GSM, UMTS, LTE and 5G NR
- Decibels and dBm: the 3 dB point, and why RF is measured logarithmically
Module 4 · Weeks 5–6 · 12 hours
RF and Cellular Networks
Antennas, links and the mobile networks operating in Tanzania.
- Isotropic, dipole, Yagi and parabolic antennas, and what a gain figure means
- Link budget calculation from transmit power through path loss to received signal
- Tanzanian operators, their technologies, and TCRA frequency allocation
- 5G: sub-6 GHz against mmWave, and massive MIMO in practice
Module 5 · Weeks 7–8 · 10 hours
Optical Fibre and Infrastructure
Light in glass, and the cabling standards that carry everything else.
- Total internal reflection, numerical aperture and attenuation in single and multimode fibre
- The full fusion splicing procedure, from stripping to heat-shrink, with target splice loss
- Reading an OTDR trace: connectors, splices, breaks and Fresnel reflections
- Structured cabling to TIA-568C — Cat5e, Cat6 and Cat6A, and patch panel discipline
Assessment and certification
Assessment is continuous and practical, combining bench measurement, calculation and a final assessment with written and practical components.
A Kevajopa Technologies Limited Certificate in Telecommunication and Electronics is awarded on satisfactory completion, with a minimum 80% attendance recorded per session.

What this programme does not cover
- Hands-on fibre splicing and OTDR certification — Module 5 teaches the principles and procedure, but the practical splicing programme is Fibre Optic Technologies.
- Network configuration and routing — that is Digital Networking.
- Electrical installation work requiring a licensed electrician.
- PCB design and manufacture.
- Any vendor or regulatory certification examination.
Fees and enrolment
TZS 450,000 for the full eight-week programme, including all instruction, bench time, use of instruments and components, course materials, assessment and the certificate. Kevajopa Technologies Limited is not VAT-registered; no VAT is charged and none should be added. Public entities deduct 2% withholding tax at source in accordance with Tanzanian law — the withholding certificate should be issued to Kevajopa Technologies Limited, TIN 172-177-301.
We do not publish a fixed calendar. An intake is scheduled once a
group has confirmed, and confirmed participants receive at least ten working days' notice of
the start date. Group rates are available for three or more registering together, and
corporate cohorts can be delivered at the client's premises.
