Federated Wireless Spectrum Access System (SAS)

Spectrum is the foundation of all wireless infrastructure systems and is highly valued because it’s finite. Historically there are two main types of Spectrum: one for carriers, which have exclusive licenses, and one for Wi-Fi systems in unlicensed bands. The FCC’s recent Report and Order (R&O) outlines a new shard spectrum innovation technology. Shared Spectrum aims to create a balance between the low cost and versatility of unlicensed spectrum and the quality and predictability of licensed spectrum.

 

The Spectrum Crunch

The widespread adoption of smartphones, laptops, and tablets running advanced applications has dramatically increased the need for more spectrum. Wireless users driven by the desire for video, and other media rich applications are creating an unprecedented spectrum crunch within wireless communications. This explosion of wireless broadband traffic has ushered in a new age of wireless, enabled by shared spectrum. Shared spectrum improves utilization by allowing multiple users, both government and commercial, to dynamically access the same spectrum resource. These frequency spectrum allocations ranged from permitting maritime navigation signals or AM radio at lower radio frequencies to providing access for services such as broadcast television, cell phones and satellite communications at higher frequencies. As the use of wireless devices has proliferated, this system of spectrum allocation has failed to keep pace with demand. This has led to calls for a new approach for a more efficient use of available spectrum by allowing it to be dynamically shared.

The Solution

Federated Wireless has developed a dynamic three-tiered Spectrum Access System (SAS), which will enable carriers and other industry participants to cost-effectively unlock the tremendous value of licensed shared spectrum. The company’s technology is positioned squarely in the critical path needed to lead the next revolution in wireless. The company’s innovative approach provides for the dynamic, secure and efficient allocation, management and sharing of spectrum resources in real time. This enhances the performance of wireless broadband networks, optimizing capacity through higher spectrum utilization, ultimately delivering a high quality of experience to the end user.

Federated Wireless dynamic Spectrum Access System (SAS) provides:

 

  • Highest and best spectrum utilization factor
  • Efficiencies across three tiers of access, supporting the federal government, carriers and the consumer
  • Neural network of radio sensors to minimize impact of exclusion zones

 

 

Federated Wireless’ SAS is a dynamic sharing solution, the model adopted by the FCC, which manages access to spectrum across three tiers of users incumbents, carriers and consumers.

Shared Spectrum is a three-dimensional challenge in that it not only needs to address sharing a band, but must also incorporate time and geographical location factors in granting access across multiple classes of users.

The SAS’s enhanced, dynamic protection capability enables Federated Wireless to narrow the time, frequency and location margins required to ensure non-interference to primary federal systems from secondary wireless systems. This makes it possible to open up more spectrum for commercial services in the locations and times needed to deploy a viable nation-wide network than what could be enabled by other Spectrum Access System providers.

In addition, Federated Wireless can ensure that the federal spectrum that has been opened for commercial purposes- as well as carrier-owned spectrum resources- is put to the most efficient use, both technically and economically.

Only Federated Wireless dynamic SAS minimizes the impact of exclusion zones. Federated Wireless’ SAS can enable wireless access inside the exclusion zones that result from the intense concentrations of radar systems that exist along our nation’s coasts. Unlike other solutions, Federated Wireless SAS understands how wireless signals and radio waves propagate through different environments, including highly complex urban areas. By utilizing a neural network of radio sensors combined with advanced radio environment mapping, propagation techniques and spectrum data analytics, our SAS can provide a fine level of detail into different environments, allowing it to help minimize interference and maximize spectrum efficiency. These technological advancements allow Federated Wireless SAS to satisfy the current FCC fixed geographic exclusion zones, as well as enable the evolution to a future regulatory environment with dynamic exclusion zones.
