The corp 148 final bundle equips the telecom tower technician (climber) in CDMX (Telmex, Telcel, ATT México, Movistar, Totalplay, Ultra, izzi Telecom, Axtel, Tower One Wireless, American Tower México, Telesites, CTI Towers, SBA Communications). Full body harness with fall arrester, certified hard hat with chin strap, protective glasses, dielectric tool kit for maintenance. The CFDI 4.0 invoice goes under USO CFDI D02 or I08 with 16% national IVA.
The CDMX telecommunications cluster operates more than 4,500 towers and rooftops with antennas for mobile services (Telcel with 4G/5G coverage, ATT México with 4G/5G coverage, Movistar with 4G, Ultra, izzi Telecom, Axtel, Totalplay, Shared Network ALTAN) and fixed services (Telmex with copper and fibre optic). The telecom corporate and the tower operator (Towercos like Tower One, American Tower, Telesites, CTI Towers, SBA Communications, UNITEC, MXT) manage preventive and corrective maintenance of antennas, radio bases, microwaves, power sources, grounding systems and fibre optic cabling.
The tower technician's (climber) work demands PPE certified under NOM-017-STPS-2008 and ANSI Z359, full-body harness with fall arrester certified under ANSI Z359.13, type II class E certified hard hat with chin strap, impact-protective glasses, dielectric tool kit for 1000V, and technical backpack for equipment transport. The corp 148 final bundle covers the initial issue of the climber, tower supervisor, radio technician and fibre optic technician.
The telecom operator invoices consolidated from its CDMX fiscal domicile (usually colonia Centro, Polanco, Santa Fe, Lomas, Del Valle, San Ángel, Roma). The tower operator invoices from its CDMX fiscal domicile or abroad (Tower One domiciled in Canada, American Tower domiciled in the US, SBA domiciled in the US) but with operations registered in Mexico. The invoice breaks down per tower, technician RFC and kit count.
The telecom corporate runs 24/7 rotating shifts that cover night-time and weekend maintenance (when the network has lower traffic), seven days a week. Climber turnover is high: the corporate reports 10% to 15% monthly turnover due to the risky nature of the work and high demand for certified climbers in other industries.
The kit ships in a rigid box sealed with the operator and technician folio, identified with name, RFC and assigned tower. Each piece carries engraving of the operator logo for inventory control and tower traceability.

The corp 148 final bundle invoices under USO CFDI D02 when booked as training expense, or I08 when booked as telecom operating expense. The operator invoices consolidated from its CDMX fiscal domicile with 16% national IVA. For towercos with foreign fiscal domicile, invoicing runs under permanent-establishment regime in Mexico. Deductibility runs under Article 27 LISR as telecom operating expense.
The telecom operator with more than 500 towers in CDMX and metropolitan area issues a single consolidated invoice with per-tower, technician RFC and kit-count breakdown. The invoice attaches the individual employment contract or service-provision contract per tower, with the list of technicians assigned to each tower. Renewal runs monthly with 7-day prior notice.
For telecom operators reporting service-quality indicators (network KPIs, MTBF, MTTR) to IFT (Instituto Federal de Telecomunicaciones), the corp 148 final bundle provides evidence of commitment: the certified harness reduces accidents, the certified dielectric tools prevent electrical incidents, the hard hat with anti-UV treatment protects on long shifts. The CFDI 4.0 invoice with certified-PPE breakdown serves as supporting documentation for the safety spend reported.
The telecom corporate runs 24/7 with night-time and weekend maintenance preferences (22 to 6 hours) when the network has lower traffic. For emergency maintenance (antenna drop, fibre cut, radio base failure), the corporate runs a 24/7 on-call crew. Climber turnover is high: 10% to 15% monthly due to the risky nature of the work.
The annual contract with safety stock and replacement within 5 business days covers the continuous flow of hires and departures at the telecom corporate. Delivery is scheduled to match hiring peaks: January (annual renewal), July (semi-annual adjustment). For urgent deliveries (technician starting the next day), we run a minimum batch of 5 kits with 8–10 business day production time.
Production runs 15 to 20 business days for series of 30 kits or more, with 20 to 25 days for series above 200 kits. Delivery to site runs via specialised carriers with 1–2 day transit for CDMX and metropolitan area. For out-of-town towers (Toluca, Cuernavaca, Puebla, Querétaro, Pachuca, Cuautla), transit extends to 2–3 days.
