A point-to-point radio path has 2 endpoints, and both require verified geometry and usable site access. We compare transport choices against the same demand forecast before selecting equipment. A rural coverage map can look complete while its upstream connection remains unresolved. The access radio reaches the intended subscribers, but the proposed aggregation tower may depend on a fiber handoff that has never been confirmed. We start with that dependency because moving the handoff can change every downstream path. Coverage and transport need separate engineering records that refer to the same site locations. **The service boundary controls the comparison.** We identify where traffic leaves the access network and where the upstream provider accepts it. For fixed wireless, that means following sector traffic through the aggregation link. For a small cell, we confirm that the requested connection is backhaul; a different radio architecture may impose fronthaul requirements that make this comparison inappropriate. The operator supplies interface and performance requirements. ### Demand before equipment We build the demand forecast from the operator's subscriber assumptions and measured traffic where available. The busy hour matters. Adding advertised customer speeds together can overstate simultaneous demand, while using a quiet-hour average can conceal congestion that subscribers experience every evening. We retain the assumptions beside the result so a changed take rate can be reflected without rebuilding the entire design argument. Traffic also has direction. Upload demand from an institutional connection can change the balance at a site that otherwise serves residential customers, and a radio's headline aggregate rate may not describe the capacity available in the direction that becomes congested. We request usable throughput for this configuration. The comparison must also include the contracted upstream service, because a larger site radio cannot expand that handoff. ### Establish the conditions for an acceptable link The operator needs to define how much service can be lost during a degraded condition. We separate normal operation from a reduced-capacity state and identify which traffic must survive. That changes a backup route's value. A standby path that keeps management access alive may be useful, but it should never appear in the plan as though it can carry the full subscriber load. A design review should expose unresolved dependencies before purchase. We want a named upstream handoff and an explicit growth assumption, with site access treated as a condition that must be confirmed. Either uncertainty makes the option conditional. This lets an owner compare a buildable alternative against an attractive but incomplete concept without mistaking the missing information for an engineering advantage. ## Compare transport choices against the same route Fiber earns its place when the operator can obtain a usable connection and support the route needed to reach it. We favor it for an aggregation location expected to grow, particularly where several access sites converge. Our preference has a weakness: a fiber-led plan can become dependent on access rights or construction work outside the operator's control. The comparison keeps that exposure visible. Licensed microwave deserves an independent path study when a physical fiber extension is difficult. It can carry traffic across terrain that would complicate a cable route, provided the endpoint geometry and performance model support the service. We do not infer feasibility from a visible tower. The antenna centerline that clears the path must also be a position the structure can support and the owner will release. Unlicensed transport can be useful where the operator accepts its operating constraints and has a credible response to interference. We assess it on that basis. A low equipment price does not settle the choice when the path is the only upstream connection for a growing service area, especially if restoring throughput would require another tower visit or a different mounting position. The table compares design dependencies, not vendor ratings. Each option below still needs project-specific engineering. | Design question | Fiber | Licensed microwave | Unlicensed radio | | --- | --- | --- | --- | | Connection dependency | Confirmed provider handoff and route | Verified endpoints and FCC process | Verified endpoints and operating constraints | | Physical feasibility | Buildable cable approach | Clearance and approved antenna position | Clearance and approved antenna position | | Capacity decision | Service commitment and terminal capacity | Throughput at required availability | Usable throughput under interference | | Growth consequence | Plant reuse and equipment upgrade | Recheck path and structural configuration | Reassess channel conditions and capacity | | Maintenance exposure | Route access and repair responsibility | Tower access and replacement configuration | Site access and interference response | ### Fiber: confirm the handoff before designing the approach A nearby cable tells us where infrastructure exists; it does not establish a service offer. We confirm the available handoff with its provider and locate the demarcation point before completing the approach design. The provider's capacity commitment belongs in the planning record. A route ending at an inaccessible splice location has not answered how the operator will connect. For a new extension, we examine the route between that demarcation and the site entrance. A roadside segment can depend on pole attachments, while the final approach may require an underground crossing. We carry those dependencies into the schedule instead of giving the entire extension the same assumed readiness. Our [fiber backhaul design discussion](/blog/fiber-backhaul-design-cell-towers) explains how the site connection and outside plant meet. Growth is easier to evaluate when passive plant and active equipment are considered separately. We identify what a future upgrade would reuse and what it would replace. Spare fiber alone does not establish available transport capacity; the provider's service and the terminal equipment still govern the connection. Conversely, an equipment change may expand usable capacity without reopening the route, which can materially improve the fiber option. ### Licensed microwave: model the proposed configuration A licensed microwave candidate needs a reproducible path profile and a link budget for the equipment under consideration. We record the antenna elevations actually proposed, including the height reference used at each site. Small input changes can alter obstruction results. A model built around a nominal tower height should remain preliminary until the intended mounting position is verified. ITU-R Recommendation P.530-19, *Propagation data and prediction methods required for the design of terrestrial line-of-sight systems*, approved September 1, 2025, is an in-force reference for propagation analysis. We use the applicable method and project inputs to evaluate fading rather than attaching a generic availability percentage to a rural path. Local conditions and the selected configuration govern the prediction. Licensing is an FCC process. The engineering plan identifies that dependency without treating a modeled path as an authorization or offering licensing advice. Our [microwave backhaul engineering guide](/blog/microwave-backhaul-design-engineering) develops the path-analysis work in more detail. Keep the equipment configuration consistent across the path study and structural review so a late substitution receives the checks it changes. ### Unlicensed links: account for the shared radio environment An unlicensed path still needs disciplined RF engineering. We assess the interference environment at the proposed endpoints and document how the selected radio configuration responds to it. A single quiet observation cannot establish future channel conditions. For planning, we want the operator to understand what would trigger investigation and what practical adjustment remains available after installation. The operating response should be specific to the site. If antenna access requires an escort or difficult travel, an option that relies on frequent physical intervention deserves a different assessment from equipment reachable through an ordinary maintenance visit. Our recommendation includes that distinction. Hardware cost can be attractive while the support burden remains a poor fit for the service being offered. Temporary backhaul needs a defined replacement condition. We identify the fiber handoff or permanent transport acceptance event that will end the temporary arrangement, and we preserve access to the equipment until removal is complete. Without that condition, a provisional link can quietly become the permanent transport plan. Its original assumptions then survive long after the subscriber demand has changed. ## Survey the radio path and the site together A desktop profile helps direct fieldwork, but the antenna location must be checked where it will be installed. We verify endpoint coordinates and the ground-elevation reference before reconciling the path model with field observations. Height errors can travel far. Our survey record distinguishes an observed obstruction from a terrain-model feature so later design changes do not erase that distinction. ### Clearance around the sightline The Fresnel region extends around the direct sightline. Cambium's LINKPlanner Online Help, version 6.4.3, describes its Profile display as showing 0.6 of the first Fresnel zone when clutter is enabled; the help page gives no publication date. That display is guidance for antenna-height selection, not a universal acceptance percentage. We review the model settings before interpreting the picture. Trees deserve particular attention where they define the limiting clearance. We document the canopy observed during the visit and distinguish it from assumed future growth. A winter photograph can leave a misleading impression of the obstruction. If the intended mounting height changes after structural review, we revisit the affected profile instead of carrying forward a clearance judgment made for another elevation. > **Keep the height reference attached to the value.** Record whether an antenna elevation is above ground or tied to a vertical datum. That small notation lets the path engineer reconcile the survey with the tower drawing without guessing what the number means. ### A clear path still needs a usable mounting position The tower review must cover the proposed antenna and its support arrangement. We carry the actual equipment configuration into that review, including the mount rather than describing the installation only by a radio model. A change in dish size can affect both the RF prediction and structural demand. Neither team should learn about the substitution from an installation photograph. Site access also determines whether the proposed position can be built and maintained. We check the route into the compound and identify restrictions that affect installation planning. For shared sites, the owner must confirm usable space. Our [wireless engineering services](/services/wireless-engineering/) bring those site constraints into the design while the antenna location can still change without undoing a released package. Power and equipment space need their own confirmation. We identify the intended supply and the space needed for transport equipment, then reconcile those requirements with the site's available facilities. Backup duration is an operator requirement to be designed around, not a value inferred from the presence of a battery cabinet. A path can remain clear while its supporting equipment loses power. ## Check capacity when the network is under stress Normal operating throughput is only part of the transport decision. We ask what happens when the link moves to a lower modulation state or traffic shifts from another site. Cambium's LINKPlanner Performance Summary distinguishes predicted throughput from link availability and reports performance at each end. We retain those distinctions when comparing the radio result with the demand forecast. ### Capacity at the required service condition For an adaptive-modulation radio, the design should show the capacity relevant to the service objective, not only the fastest operating mode. We compare the traffic requirement with the performance predicted at the required availability. Where those do not align, the owner needs a changed configuration or a revised service expectation before equipment is ordered. A passing receive-level check alone leaves that decision unresolved. The upstream path must be examined as a connected system. An aggregation link may receive traffic from several access sites that are individually within their limits, yet their combined busy-hour demand can exceed the shared connection. We put that aggregation point in the capacity model. Small-cell transport requirements also need to remain visible through intermediate equipment, including any operator-specified latency or synchronization conditions. > **Retain the degraded-capacity result.** Put the usable throughput at the required service condition beside the normal operating result. The operator can then decide whether the link meets the intended service before a favorable headline rate takes over the discussion. ### Diversity and acceptance A backup route should be evaluated for shared failure points. We trace where the proposed paths meet and whether they rely on the same powered equipment. A radio and a fiber connection can still fail together at a common aggregation cabinet. The plan should say which failure the alternate route addresses and what load it can carry during that event. Acceptance criteria should follow the assumptions used to choose the transport. We define the handoff test and the radio observations needed to compare installed behavior with the design. An unexplained difference in received level deserves investigation even when traffic passes during commissioning. Recording the installed configuration makes that investigation possible without reconstructing antenna details from incomplete purchase records. Keep field data usable after commissioning. We preserve the coordinate reference with the endpoint record and connect the installation observations to the final drawing revision. Our [field survey data management guidance](/blog/field-survey-data-management-telecom) covers that handoff discipline. When maintenance returns to a rural site, the team needs to know which measurements describe the installed link and which belonged to an earlier alternative. ## Wireless backhaul planning rural broadband: choose the next design step **Rural ISP extending coverage:** confirm the upstream service and complete the limiting path survey before selecting the access site's backhaul radio. Choose licensed microwave when the engineered path supports the service and a practical fiber connection remains unresolved. Use unlicensed transport only with an operating plan that accepts the interference exposure and identifies a workable response if usable capacity falls. **Small-cell operator adding sites:** obtain the transport requirements from the network owner before comparing media. Carry those requirements through the aggregation point, including the degraded condition. Favor a confirmed fiber handoff where it satisfies the connection and growth needs; consider radio where the complete transport design meets the same requirements and the proposed mounting position is available. **Owner planning a permanent rural network:** compare the durable route against the full obligations of any interim link. Keep the future fiber approach in the design while checking the radio alternative, and establish who will accept the permanent handoff. We recommend making the transition condition part of the scope so a temporary installation does not become an undocumented constraint on later expansion.

Use that review to establish the route's engineering scope while the upstream connection and final site approach are still being resolved. ## Frequently Asked Questions ### What must be confirmed at each backhaul endpoint? For a point-to-point radio link, both of its 2 endpoints need verified coordinates and a consistent elevation reference. We also confirm the proposed antenna position with the site owner. The survey must distinguish what was observed from what remains assumed, because a later change in mounting height can alter the path profile and require the clearance assessment to be repeated. ### Does a clear sightline prove a microwave path will work? No. Clearance around the sightline and predicted performance still need review for the proposed equipment. LINKPlanner's Profile guidance shows 0.6 of the first Fresnel zone when clutter is enabled, but that visualization is not a universal pass criterion. We verify the model settings and assess the limiting obstruction at the intended antenna elevations before treating a candidate path as feasible. ### How should an operator compare radio capacity with demand? Compare usable throughput in the required service condition with the operator's busy-hour traffic forecast. LINKPlanner Online Help 6.4.3 separates throughput predictions from availability, which prevents a headline rate from standing in for the whole decision. We also examine traffic direction and the shared upstream connection so a satisfactory individual radio result does not conceal congestion at the aggregation point. ### Who performs Draftech backhaul engineering and construction? Draftech performs engineering 100% in-house, keeping the path design and site requirements within its engineering scope. Full turnkey construction is delivered by Draftech-managed subcontract crews.
