What is fixed wireless broadband?

Terrestrial fixed wireless is the second-largest broadband technology by FCC Form 477 deployment records, 9,599,266 records nationwide, behind only satellite. Despite this scale, many readers are unfamiliar with how the radio path works and how the FCC files it. This guide explains the technology, its variants, and its place in the Form 477 record.

How Fixed Wireless Works

Fixed wireless broadband uses radio signals transmitted between a tower or base station and a receiver (antenna) mounted on or near the subscriber's building. Unlike mobile wireless (4G/5G on your phone), the receiver is stationary, which allows for higher-gain antennas, more stable connections, and better throughput. The tower connects to the internet backbone via fiber or high-capacity microwave links, then distributes that connectivity wirelessly to nearby subscribers.

The range and performance of fixed wireless depend on the frequency band used, the terrain, and whether line-of-sight exists between the tower and the subscriber. Higher frequencies (like millimeter wave 5G) offer faster speeds but shorter range and require clear line of sight. Lower frequencies penetrate obstacles better and reach farther but offer lower speeds.

Licensed vs. Unlicensed Spectrum

The FCC distinguishes between licensed and unlicensed fixed wireless, and this distinction matters for service quality. Licensed fixed wireless uses radio spectrum purchased from the FCC through auctions. The license holder has exclusive right to that frequency in a geographic area, which means no interference from other users and more predictable, reliable performance.

Unlicensed fixed wireless uses shared spectrum bands (commonly 2.4 GHz, 5 GHz, and 60 GHz) that anyone can use without an FCC license. While this makes deployment cheaper, it also means potential interference from other users and devices operating on the same frequencies. Unlicensed fixed wireless is popular among smaller ISPs serving rural areas because it avoids the significant cost of spectrum licenses.

In the FCC Form 477 fixed-deployment data, both licensed and unlicensed systems are reported under a single Terrestrial Fixed Wireless technology code, which accounts for 9,599,266 deployment records nationwide, the second-largest category after satellite. The filing does not separate the licensed and unlicensed shares.

Typical Performance

Modern fixed wireless systems can deliver speeds comparable to wired broadband in many cases. Licensed fixed wireless services commonly offer 25-100 Mbps, with some providers offering plans up to 1 Gbps in ideal conditions. Latency is typically 10-30 ms, which is adequate for most applications including video conferencing and online gaming. However, performance can degrade during heavy rain, snow, or high winds, especially at higher frequencies.

The biggest variable in fixed wireless performance is the distance and terrain between the subscriber and the tower. Subscribers with clear line of sight to a nearby tower will get the best performance. Those behind hills, dense foliage, or tall buildings may experience reduced speeds or may not be serviceable at all.

Where fixed wireless shows up in the filing

Form 477 does not say when fixed wireless is the best buy. Rural, small-town, and suburban-edge census blocks often appear in this technology code because a tower can be filed without a fiber drop to every home. That is a filing fact, not a purchase recommendation.

A second wired provider in the same block is also just a second row in the extract. Pricing and service quality are outside this dataset.

Fixed Wireless vs. Mobile 5G Home Internet

T-Mobile and Verizon offer 5G home internet services that are technically a form of fixed wireless, but they use the existing mobile cellular network rather than dedicated fixed wireless infrastructure. The key difference is capacity management. Dedicated fixed wireless networks are sized for their subscriber base. Cellular-based services share capacity with all the phones and devices on the same cell tower, which can lead to more variable performance, especially during peak mobile usage hours.

The Future of Fixed Wireless

Fixed wireless is expected to play an increasingly important role in broadband deployment, particularly as the technology improves and federal funding drives infrastructure expansion in rural areas. Advances in antenna technology, spectrum allocation, and signal processing continue to push speeds higher and coverage wider. For the millions of Americans in areas where wired broadband is not economically viable, fixed wireless represents the most practical path to reliable, high-speed internet.
