Trenching fiber can cost tens of thousands of dollars per kilometre and take months of permits. Fixed wireless delivers high-capacity broadband between towers, rooftops and poles in days, and today's systems reach multi-gigabit speeds. It is how operators reach rural customers, how resorts and campuses connect remote buildings, and how many Wi-Fi networks get their backhaul.
Two architectures
Point-to-Point (PtP): a dedicated link between two sites. Ideal for backhaul and building-to-building connections, spanning from a few hundred metres to tens of kilometres.
Point-to-Multipoint (PtMP): one base station sector serves many subscriber units. This is the model behind most Fixed Wireless Access (FWA) networks, and the newest platforms can work in near and non-line-of-sight conditions.
Choosing the right spectrum
5 & 6 GHz (unlicensed): best for low-cost PtP and PtMP access. Watch out for interference; 6 GHz rules vary by country.
CBRS, 3.55–3.7 GHz (US): best for private LTE/5G and FWA with managed shared spectrum. Watch out for SAS registration and certified installers.
Licensed microwave, 6–42 GHz: best for carrier-grade backhaul with interference protection. Watch out for licensing time and fees.
mmWave, 60 GHz / 70–80 GHz: best for multi-gigabit to 10+ Gbps over short links. Watch out for rain fade and strict line of sight.
What makes a link work
Fresnel zone clearance: keep at least 60% of the first Fresnel zone free of trees, roofs and terrain.
Link budget and fade margin: design for the worst day, not the average one, especially above 10 GHz where rain matters.
Capacity planning: size each sector for peak-hour demand and realistic oversubscription.
Site survey and mounting: height, structure and alignment decide whether the design on paper performs in the field.
