A 60GHz point-to-multipoint network is built around one straightforward idea: a single hub radio, mounted at an elevated vantage point, serves many subscriber terminals simultaneously across a sector-shaped coverage area, rather than the one-to-one link that defines traditional point-to-point microwave. That architectural choice is what makes PtMP economical at scale, since operators are not building a dedicated radio pair for every single customer connection. It is also what makes the underlying market, the 60GHz mmWave wireless backhaul market, grow through unit economics rather than through a handful of large point-to-point contracts.
Every PtMP deployment rests on three hardware building blocks: the base station or hub radio, the subscriber unit or CPE terminal installed at the customer premises, and, increasingly, an integrated or beamforming-enabled variant that blends elements of both roles. How an operator combines these three components determines coverage radius, per-sector capacity, and ultimately how many paying subscribers a single tower or rooftop installation can support.
The hub radio is the anchor of any PtMP sector. It typically integrates a sectorized antenna array, radio electronics, and a network-facing interface into a single rooftop or tower-mounted unit, and its design directly caps how many subscriber terminals a single sector can serve without capacity contention. Engineers evaluating hub radios weigh sector angle, aggregate throughput, and the number of simultaneous client connections a chipset can manage, since these three variables trade off against each other in ways that are not always obvious from a spec sheet alone. Readers comparing specific hardware platforms will find a fuller picture in our overview of leading 60GHz PtMP equipment vendors, which lays out how different manufacturers approach this same design problem.
Hub placement matters as much as hub selection. A rooftop with clean line-of-sight across a dense subscriber cluster will outperform a technically superior radio mounted somewhere with partial obstruction, which is why site survey work remains a labor-intensive, non-automatable part of every PtMP rollout regardless of how advanced the hardware becomes.
Subscriber units, commonly called CPE or customer premises equipment, are the terminals installed at each individual connection point, whether that is a home rooftop, a small cell cabinet, or an enterprise building facade. Because a single hub radio can serve dozens of CPE terminals, this segment carries the highest unit volume in the entire PtMP hardware category, and installation quality at the CPE end is frequently the deciding factor in whether a subscriber experiences a stable link or a frustrating one.
Installation considerations for CPE units include precise antenna alignment, since 60GHz signals are highly directional, and weatherproofing, since these terminals are almost always mounted outdoors and exposed to the same rain-fade conditions that affect the broader link budget. Self-install CPE kits are gaining traction in residential fixed wireless access, but professional installation remains standard for enterprise and small cell backhaul connections where link reliability carries a service-level commitment.
Integrated antenna-radio systems combine the antenna and radio electronics into a single weatherproof housing, reducing the number of separate components an installer needs to align and maintain. This simplification appeals particularly to system integrators managing large multi-site rollouts, where fewer parts per installation translates directly into lower field-service overhead across a growing subscriber base.
Beamforming-enabled mmWave nodes represent the more advanced end of the architecture spectrum. Rather than radiating a fixed directional pattern, these nodes electronically steer and shape their signal beam, which improves link reliability in environments with partial obstructions and reduces interference with neighboring PtMP cells operating in the same unlicensed band. This capability commands a price premium over fixed-beam hardware, but it is increasingly viewed as a necessary investment in dense urban markets where multiple operators now compete for the same slice of 60GHz spectrum.
Vendors differentiate beamforming implementations by the number of independently steerable channels a single node supports and by how quickly the beam can reacquire a subscriber link after a temporary obstruction, such as a passing vehicle or a swaying tree branch. Field engineers evaluating competing beamforming platforms tend to weigh reacquisition speed heavily, since a beam that recovers in milliseconds is functionally invisible to the end user, while one that takes several seconds produces a noticeable, complaint-generating stutter on video calls and streaming traffic.

TECHNOLOGY WATCH Beamforming is shifting from a premium option to a near-default requirement in dense urban PtMP deployments, as unlicensed-band interference management becomes a bigger engineering constraint than raw throughput. |
Hardware choices only make sense in the context of a deployment model, and 60GHz PtMP networks are typically built around one of four models: fixed wireless access, small cell or 5G backhaul, enterprise private networks, and smart infrastructure networks. Each model imposes different requirements on hub density, CPE volume, and beamforming necessity. The specific industries adopting each of these models, and the use cases driving that adoption, are explored further in our analysis of last-mile broadband and smart city applications built on this same architecture.
Fixed wireless access deployments prioritize CPE volume and coverage radius over raw per-link capacity, since the goal is connecting as many residential and small business subscribers as possible within a sector's footprint. Small cell and 5G backhaul deployments flip that priority: a much smaller number of high-capacity, low-latency links connect cell sites back to the core network, which places a premium on hub radio throughput and beamforming precision rather than terminal count.
This distinction matters for procurement planning, because a hub radio optimized for maximum subscriber count is not necessarily the right choice for a small cell backhaul contract with strict latency guarantees, and vendors increasingly differentiate their product lines along exactly this line.
Enterprise private networks use PtMP architecture to connect multiple buildings across a campus or industrial site without the cost and disruption of trenching fiber between them, often paired with integrated antenna-radio systems chosen for ease of maintenance by in-house facilities teams. Smart infrastructure networks, covering applications like traffic-camera backhaul and municipal sensor grids, tend to favor a hybrid of standard hub radios and beamforming nodes depending on how densely packed the sensor network is across a given district. Deployment choices in these settings are gated by region-specific spectrum rules, particularly for government and defense-adjacent installations, which architects must confirm before finalizing an architecture for cross-border or multi-jurisdiction rollouts.
Deployment complexity also scales with regulatory exposure. A standard rural fixed wireless access rollout in a single country involves a relatively contained set of design decisions, while a multinational enterprise private network or a defense-grade smart infrastructure build must account for certification differences, procurement approval cycles, and hardware sourcing constraints that vary sharply from one jurisdiction to the next. Architects working across several regions at once tend to standardize on a smaller set of certified hardware platforms specifically to avoid re-litigating these design decisions market by market.

PROCUREMENT INSIGHT System integrators evaluating architecture for a new deployment should scope the use case first, subscriber-dense FWA versus low-latency backhaul versus campus connectivity, since that decision drives hub, CPE, and beamforming requirements far more than any single spec-sheet comparison between vendors. |
