What it costs

One crew day: 17.570 TL/day (worked out)

A day of the fitting and maintenance crew: bucket truck 2.000 TL x 8 hours x 0,7 = 11.200 TL (a certified operator comes with the hire); electrician, a thirtieth of the middle of the monthly range, 95.000 TL, 3.170 TL; helper, the large-city top of the band, 3.200 TL. 17.570 TL in all. A maintenance visit is this divided by the sites the crew reaches on that structure in a day: 17.570 / 8 = 2.196 TL on a lighting column, 17.570 / 4 = 4.392 TL on a rural distribution pole and in a tunnel. A roof needs no bucket truck: 6.370 / 4 = 1.592 TL.

Lighting columns: 8 sites/day (worked out)

How many lighting columns a crew fits or visits in a day. A published example: 11 crews replaced 414 luminaires on 207 poles over one weekend, 18,8 poles and 37,6 luminaires a crew. The report does not give the hours, only that the work ran day and night; counting 12 hours of each of the two days, a crew replaced 1,6 luminaires an hour, 12,5 in an eight-hour day. A YERKON unit is one clamp and one supply tap on a column, no more work than a luminaire. 8 a day is a cautious figure below that; an hour a column.

Rural distribution poles: 4 sites/day (worked out)

How many distribution poles a crew reaches in a day in open country. Town counts an hour of work a column (columns a crew reaches in a day, the Dicle Elektrik example). Open country adds the road: two hours of the eight-hour day to and from the base, half an hour between sites (YERKON's estimate of the road). (8 - 2) / (1 + 0,5) = 4.

Tunnel: 4 sites/day (worked out)

How many units a crew fits or visits in a tunnel in a day. The work waits on the highways authority's lane closure, whose setting up and taking down takes part of the day.

Raising a mast: 191.890 TL (worked out)

A twenty-five metre mast and its fitting. No price is published for 25 m; the 20 m pole's price is carried to 25 m by the simulation's mast rule (cost grows with the square of height): 120.000 x (25 / 20)² = 187.500 TL. The 30 m price rises faster than that rule (475.000 TL), so this value errs low. Fitting is a quarter of a crew day, 4.392 TL: 191.892, rounded to 191.890 TL. The foundation and crane are not priced apart.

On a lighting column: 12 m (standard)

How tall the lighting column a unit stands on is. In TEDAŞ's table the heights are a set, 6, 8, 10, 12, 14 m, by road class. Kızılay's main streets are M1 to M3, so 10 to 14 m; 12 m is the middle of that. The town row was run at every value of the set (29 September 2026): at 8 m HPE P95 9,07 m, availability 94,96 %, CAPEX 10.093 TL/km²; at 10 m 8,83 m, 96,18 %, 9.373 TL/km²; at 12 m the table's own figures; at 14 m 8,67 m, 96,82 %, 8.990 TL/km². Availability and cost improve smoothly with height and P95 does not: P95 at 12 m is higher than at 10 m and 14 m. P95 is the tail of eight shadow draws, so it moves this much.

On a distribution pole: 10 m (assumption)

How high a unit stands on a rural distribution pole: the pole's height above ground less 2,5 m to the medium-voltage conductors. The pole lengths are a set (TEDAŞ) and the distance comes from the regulation; no source was found for how much of the pole is buried, so the value is still an assumption. The rural row was run at three heights on the same placement (29 September 2026): at 6 m HPE P95 8,67 m, availability 91,00 %, area 327,50 km², CAPEX 1.233 TL/km²; at 8 m 8,22 m, 93,26 %, 344,58 km², 1.172 TL/km²; at 10 m the table's own figures.

One unit's yearly consumption: 3 kWh/year (worked out)

One broadcast unit's yearly consumption. The unit spends nearly all its time listening: the SX1280 draws a few mA doing that and the microcontroller one or two, under 30 mW together at 3,3 V. With the mains converter's idle loss and the replies it sends, the average stays under 0,34 W, which is 3 kWh a year. That is a generous upper bound.

Maintenance visits a year: 0,20 visits/year (design choice)

How often a unit is visited a year. The central system sees every unit's status (each unit sends a regular "still working" message), so a crew goes when one fails rather than by the calendar. One failure in five years is a pessimistic figure for a sealed board.

The full daily allowance of one crew member for a day spent outside the place of duty.

Distribution pole rent, a year: 0 TL/year (design choice)

What the distribution company charges a year to carry a unit on its pole: nothing. The units go up under a public-sector agreement, with the prospect of being included in public structures that already stand, such as ITS cabinets, roadside units and distribution poles. Nor has any distribution company published a fee for equipment on its poles: the transport ministry's rights-of-way rules, Türk Telekom's connection fees and the General Lighting Regulation name no per-pole fee. Fees charged to commercial users, for comparison: distribution companies have rented advertising space on their poles since 2015 with the regulator's leave, the smallest poster 4.700 TL a month (Tr724, 11 May 2019); Istanbul Metropolitan Municipality's 2025 tariff charges 24.500 TL a year for a repeater or small cell on its property, and twice the site selection fee for a cabinet on a BEDAŞ or AYEDAŞ lighting column. Without the agreement, 1.200 TL a pole a year would raise rural OPEX by about half.

Cellular data line, a year: 0 TL/year (design choice)

What a year of data costs a unit with no line of its own: nothing, because no unit carries a SIM card. A unit on a structure with a line reaches the centre over it: the tunnel's communications spine in a tunnel, a signalised junction's cabinet in town, an ITS point on the road in open country. A unit with no line passes its messages by its own radio to the nearest unit that has one. Each unit sends the centre a short "still working" message at regular intervals, and a unit whose message stops coming is taken as failed. When a receiver sees GPS jamming or spoofing it passes that to a nearby broadcast unit, and the warning reaches the centre the same way.

Central system, a unit a year: 237 TL/year (worked out)

Each unit's yearly share of running the central management system. The system is the software that watches the units' records and tells the crew of a failure, and the person who runs it. One day a week of a developer: 95.000 x 12 x 0,2 = 228.000 TL; two servers backing each other up: 2 x 374,90 x 12 = 8.998 TL. 236.998, rounded to 237.000 TL a year. One person one day a week and two servers can watch the records of a thousand units, and the table prices the units at a thousand. So the cost is split across a thousand units: 237.000 / 1.000 = 237 TL a year. One day a week and a thousand units are YERKON's operating choice.
