Band 54

(1) NPRM (Notice of Proposed Rulemaking) is related to the NOAA spectrum from 1675-1680 MHz

In concert with Ligado Networks, Select Spectrum is offering 5 MHz of contiguous FCC licensed broadband spectrum, standardized by 3GPP as b54/n54 (1670-1675 MHz). Band 54 spectrum is the ideal choice for companies in the Utility and Critical Infrastructure Industry (UCII) sector that require their private network to support a range of 4G LTE, 5G NR, LTE-M & NB-IoT applications. These prime lower mid-band frequencies are available on a nationwide basis allowing UCII users increased network design flexibility, expanding the range of devices that can be connected via the private wireless network. Organizations may lease the use of the spectrum license in an area that match their operating territory.

KEY BENEFITS OF Band 54 SPECTRUM

Licensed, Dedicated Use

Licensed, lower mid-band spectrum in Band 54 enables effective wide-area broadband coverage, providing a superior option for organizations looking to deploy Private Networks. Companies in the UCII sector that establish wireless networks depend on high levels of network availability and reliability to enable Mission Critical applications. This exclusive-use spectrum can serve an enterprise’s objectives in areas ranging from a single facility to a multi-state service area.

Nationwide licensed spectrum between 1670-1675 MHz – available today
- Ubiquitous, nationwide, geographic coverage in all 50 states and U.S. Territories
- No clearing required (greenfield spectrum, available today for localized leasing)
- Licensed, dedicated use solution tailored to your organization’s geographic scope of operations
- 4G LTE, 5G NR, LTE-M & NB-IoT Ready
Ideal for the highest possible levels of network quality and scalability –offering the ability for rapid deployment. Fully licensed exclusive use spectrum that will support operations and devices for decades into the future.

Band 54 Spectrum Attributes

Band 54’s 1670-1675 MHz frequencies provide an optimal combination of capacity and coverage characteristics to deliver cost-effective and superior performance for 4G/5G service deployments.

5 MHz contiguous capacity - sufficient for nearly all targeted Private 4G/5G applications
Location in “Goldilocks” coverage and capacity zone offers reduced operating expenses through the lower mid-band propagation characteristics
Licensed spectrum to support a scalable quality network and high performance that decrease total cost of ownership
Support for highly efficient and flexible TDD operation of industrial and private network systems
- Time Division Duplex “TDD” spectrum allows both uplink and downlink in the same 5MHz frequency band. Users may adjust timing ratio to optimize for more uplink traffic, such as in sensor monitoring and control situations, or for more downlink centric traffic, e.g., in content streaming applications

Low Latency

Band 54 4G/5G systems are designed for mobile broadband providers to support very low latency that certain applications require, including for network protection, and synchrophasors. The band features a 5 MHz wide carrier that is necessary for transition to 5G services including for applications that use 5G ultra-reliable low latency communications (URLLC).

Advantages Compared to Other Spectrum Bands

Immediate spectrum availability with no risk of time delays associated with clearing existing users
Exclusive use means no sharing or deference to priority incumbents required
Future proof networks with 4G LTE, 5G NR, LTE-M, NB-IoT capable spectrum
TDD operation is significantly more efficient use of spectral capacity than FDD for most private network deployments
Option to combine with systems using higher mid-band spectrum, such as CBRS, increasing cell-site size, reducing deployment costs, and increasing capacity
No risk of interference into (or from) adjacent land mobile radio systems; no re-tuning of existing land mobile radio systems required
