At Lumaryon Universal, customer satisfaction is our priority. If you are not completely satisfied with your purchase, you may request a return within the eligible return period as outlined on our website. Items must be returned in their original condition, unused, and in original packaging to qualify for a refund.
Once your return is received and inspected, we will notify you of the approval or rejection of your refund. Approved refunds will be processed to the original method of payment within a reasonable timeframe. Shipping fees are non-refundable unless the return is due to a defective product or an error on our part.
Customers are responsible for return shipping costs unless otherwise stated.

We recommend contacting our support team before returning any item to ensure a smooth and efficient return process.

This Handbook has three objectives: 1) to serve as a primer for explaining the complex issues around the use of electromagnetic spectrum; 2) to analyze, from both an economic and a legal perspective, the regulatory processes being considered or underway to reallocate or change the use of spectrum bands; and 3) to be a reference source for industry professionals. Part I of the Handbook provides an overview of the spectrum and the regulatory process. Part II of the Handbook explains the various available spectrum bands, discussing their range, location, and physical properties and how these impact their ability to be used. Part III of the Handbook explains valuation issues. Part IV contains an international comparative analysis of spectrum regulation and allocation. An analysis of the current allocation of these spectrum bands in the United States follows. Part IV contains detailed explanations of the various spectrum band plans. Throughout the Handbook, we provide links in the footnotes to sources for additional information.
