Site feasibility, pole loading analysis, fiber fronthaul design, ROW permitting, and utility coordination for 5G densification programs. 600+ engineers across all 48 continental states.
Small cells are low-power wireless nodes deployed on streetlights, utility poles, building facades, and dedicated small structures to densify 5G coverage in urban and suburban environments. Unlike macro towers, which can be miles apart, small cells must be placed every few hundred meters — or closer for millimeter wave frequencies — to deliver the coverage and capacity that 5G densification programs require.
Engineering a small cell deployment is not simply selecting a pole and ordering equipment. Each site involves a sequence of technical and permitting tasks: site feasibility analysis, pole loading analysis to confirm the attachment structure can support the new equipment, fiber fronthaul or backhaul route design, conduit and innerduct routing, municipal right-of-way permits, utility pole attachment applications, power coordination with the relevant utility, and finally as-built documentation once the site is installed. For a single small cell, this can involve interactions with three or four different entities — the municipality, the pole owner, the electric utility, and the wireless carrier — all on different timelines and with different application requirements.
Scaled to a 5G densification program covering hundreds or thousands of sites across a city or metro area, the coordination complexity is substantial. Draftech provides end-to-end small cell and 5G engineering services — from initial site walk to construction package to as-built — with project management infrastructure designed for high-volume concurrent deployment programs.

Our small cell engineering work integrates directly with our OSP engineering and fiber network design capabilities — the fronthaul fiber that connects small cells to the core network is OSP design work, and it's designed by the same team handling the wireless infrastructure engineering. That integration matters for project schedule and for design quality.
5G mmWave frequencies — operating in the 24 GHz to 100 GHz range — have very limited propagation. Unlike sub-6 GHz 5G, which behaves more like LTE and can cover hundreds of meters to a mile from a single site, mmWave signals attenuate rapidly and are blocked by buildings, foliage, and even heavy rain. Dense urban deployments require small cells every 100 to 300 meters, and sometimes closer.
This creates volume that drives the engineering challenge. A single city block in a dense urban environment may require 6 to 12 small cell attachments to achieve adequate mmWave coverage. Each of those sites requires a pole loading analysis, a pole owner application, ROW permits from the municipality, and power coordination with the utility serving that block. Multiply that across a multi-block deployment area and the parallel workstreams become a significant engineering and project management exercise.
RF propagation analysis identifies where coverage gaps exist. Engineering screens candidate poles and structures for structural suitability, permitting pathway, and fiber connectivity options before committing to detailed engineering.
NESC-compliant structural analysis determines whether each candidate pole can support the proposed small cell equipment without exceeding allowable loads. Poles that need reinforcement or replacement go into the make-ready package.
Municipal ROW permit applications and pole owner applications are submitted in parallel wherever possible. Waiting to complete one before starting the other adds months to project timelines on high-site-count programs.
Fronthaul fiber routes are engineered concurrently with the wireless site permitting — so fiber conduit permit applications can run simultaneously with the small cell ROW applications instead of sequentially.
Complete construction documents for each site — mounting detail drawings, fiber termination schedules, power drop specifications — followed by as-built documentation after installation for carrier records and future maintenance reference.
Timeline from site selection to energized site runs 12 to 24 months in complex jurisdictions — driven primarily by permit processing times, not engineering. Municipalities with streamlined small cell ordinances (aligned with the FCC's 2018 small cell rules) can move faster; others with extensive local review processes are the pacing items for deployment programs. Draftech's project management approach is designed to run every workstream as concurrently as regulations allow, minimizing the sequential dependencies that stretch timelines.
FCC context: The FCC's 2018 Small Cell Order (FCC 18-133) established shot clocks for municipal small cell permit processing — 60 days for collocations on existing structures, 90 days for new structures — and capped application fees at reasonable rates. Not all jurisdictions have fully aligned their local processes with these federal rules, and timeline variability across markets remains significant. Draftech tracks permit timelines across active markets and can advise on expected processing times before site selection is finalized.
Every small cell needs fiber connectivity to function. Fronthaul refers to the connection between a distributed radio unit (the antenna hardware at the small cell site) and the baseband unit or centralized processing hardware. Backhaul carries aggregated traffic from the baseband unit back to the core network. Both have their own latency, bandwidth, and physical design requirements.
Fronthaul latency requirements are demanding. Traditional CPRI (Common Public Radio Interface) fronthaul requires one-way latency under 100 microseconds — which at the speed of light in fiber (roughly 200,000 km/s) limits the physical fiber path to about 10 kilometers between radio unit and baseband unit. eCPRI (evolved CPRI), used in more modern Open RAN deployments, offers somewhat more flexibility but still imposes tight timing constraints — typically under 25 microseconds for timing-sensitive functions like coordinated multipoint transmission.
What this means for fiber design:
Draftech fronthaul designs include a latency budget table as a standard deliverable — feeder path length, splice and connector contributions, and total modeled one-way latency against the specified fronthaul interface requirement. If a proposed route doesn't meet budget, we identify it before construction, not at commissioning.
The majority of small cells in urban and suburban environments attach to utility company poles or municipality-owned streetlight poles. Both require formal joint use applications — and both involve coordination processes that are outside the carrier's direct control.
Utility pole owners require joint use applications that include a description of the proposed attachment, equipment specifications, and a pole loading analysis demonstrating NESC compliance. The pole owner reviews the application, may require modifications, and issues a permit or attachment agreement — on their own timeline, which varies significantly across utilities. Electric utilities that have invested in streamlined joint use processes can turn around applications in weeks. Those without dedicated joint use teams may take six months or more.
Draftech manages joint use notification submissions through the NJUNS (National Joint Use Notification System) used by many electric utilities, tracking application status and coordinating responses to pole owner requests for additional information.
When poles require make-ready work before the small cell can attach — existing attachers need to be moved to restore clearances, or the pole itself requires replacement — we coordinate with the pole owner and incumbent attachers on make-ready sequencing and timing.
Some pole owners require a post-installation inspection to confirm the small cell was installed per the approved drawings. We provide inspection coordination and any required as-built documentation to satisfy the pole owner's records requirements.
For streetlight pole attachments, the process varies by jurisdiction. Some municipalities manage their own streetlight inventory and process applications directly. Others contract with third-party pole administrators or run streetlight programs through the local electric utility. Draftech maps the correct application pathway for each jurisdiction before work begins — submitting to the wrong entity is a surprisingly common cause of permit delays on small cell programs.
Power coordination is a parallel workstream. Small cells require electrical service — typically from the nearby utility distribution system — and the process of obtaining a new service point or modifying an existing one involves the utility's construction operations group on a separate application track from the pole attachment process. We manage power coordination in parallel with the attachment process to avoid situations where the pole attachment is approved but the power connection takes an additional six months.
See our permitting services page for additional detail on our ROW and utility coordination capabilities across jurisdictions.
A macro cell is a traditional cellular tower — large structure, high power output, covering a radius of one to several miles. A small cell is a low-power wireless node deployed much closer to the ground on streetlights, utility poles, building facades, or dedicated small structures. Small cells cover a much smaller area (100 meters to about half a mile depending on frequency) but can deliver high capacity in dense environments where a distant macro cell would be congested. 5G mmWave bands have very limited propagation — often just 100–300 meters in dense urban conditions — making small cells the only viable way to deploy mmWave coverage at scale.
Timeline from site selection to an energized small cell varies widely — from as few as 6 months in simple jurisdictions to 24 months or more in complex urban environments. The major variables are municipal ROW permitting (some cities have streamlined processes; others have extensive review timelines), pole owner application processing, and make-ready work when the pole needs structural modifications before the small cell can attach. Draftech processes engineering packages and permit applications in parallel wherever possible to compress overall timeline — the engineering work for fronthaul fiber, the wireless attachment permit, and the power coordination all run concurrently rather than sequentially.
Yes, in virtually all cases. Utility poles and streetlight poles have defined loading capacities, and adding a small cell — with its equipment enclosure, antenna array, fiber cable, and power cabling — adds both dead load and wind load to the structure. Most pole owners require a pole loading analysis compliant with NESC standards as part of the joint use application. If the analysis shows the pole is over capacity with the new attachment, make-ready work (pole replacement or reinforcement) is required before the small cell can be installed. Draftech provides pole loading analysis as a standard component of our small cell engineering packages.
Fronthaul requirements depend on the radio architecture. CPRI fronthaul requires latency under 100 microseconds one-way, limiting the physical fiber path to roughly 10 km between radio unit and baseband unit. eCPRI is more flexible but still has latency budgets typically under 25 microseconds for timing-sensitive applications. From a fiber design standpoint, this means minimizing splice counts on fronthaul routes, using dedicated wavelengths or dark fiber without excess patching, and providing redundant paths where the latency budget permits. Draftech includes a latency budget table in fronthaul route design deliverables so carriers can confirm compliance before construction begins.
Yes. With 600+ engineers operating across all 48 continental states, Draftech is structured for concurrent small cell programs across multiple jurisdictions. Large carrier densification programs often require engineering and permitting work running in parallel across dozens of municipalities. We assign dedicated project managers to multi-city programs and maintain consistent engineering standards and documentation formats across all sites. Carriers and tower companies managing high-volume small cell programs can work with a single Draftech team coordinating across all active markets.
