The Problem

Insufficient Spectrum

wireless operator s view
Wireless Operator’s View

“A wireless operator without enough spectrum is like a body without enough blood… If you don't have enough blood you're going to face major medical challenges. Likewise, Wireless operators will need more spectrum to be able to offer new services and applications.”

-Ali Tabassi, Vice President Innovative Technologies, Sprint-Nextel

Wireless Strategies Inc.

equipment manufacturer s view
Equipment Manufacturer’s View

In 2006, the CEO Council (CEOs from Motorola, Intel, IBM, HP, Dell etc.) called on the U.S. government to find more spectrum for use as new applications emerge.

the problem7
The Problem
  • The amount of microwave spectrum is finite and has been assigned.
  • It takes many years for the FCC to go through the regulatory process of re-assigning spectrum (usually from Point-To-Point Fixed to Multipurpose, PTMP/Mobile).

In a Perfect World there is only the Main Lobe,

and therefore only the Main Lobe has to be

considered

Path Coordination

In the Real World there are Side Lobes and therefore the Side Lobes must be Concurrently Coordinated with the Main Lobe.

the status quo
The Status Quo

Paths designed for and operated with Legacy Equipment have not put the Antenna Side-Lobe Radiation to Productive Use.

The Industry Opportunity

Use Emerging (IEEE 802.16 – WiMAX – TDD – Smart Antenna) Technologies to Put the Antenna Side-Lobe Radiation to Productive Use Under Existing Rules without Causing Additional Interference.

Win-Win Opportunity
  • Wireless Carriers: New Customers, Higher Revenues, Higher Profits/Lower Costs and Shorter Service Provisioning Times
  • Spectrum Managers: Increase in Prior Coordinations and Monitoring Services, Increased Revenues and Profits
  • FCC: Supports the Commission’s goal of Maximizing the Effective use of Spectrum.
  • Public Interest: More Competition for their Business, More Features and Lower prices

innovation
Innovation

The FCC has consistently promoted the national policy set forth in Section 257 of the Communications Act by enabling industry operators and equipment providers to maximize the efficient use of spectrum and facilitate innovative services and product offerings.

facilitating innovation
Facilitating Innovation

The Commission’s Rules specify the technical requirements (not how the technical requirements are met)

regulations specify
Regulations Specify
  • The Shape and Size of the Radiation Pattern Envelope (Tx power x antenna gain) and the location from which it emanates.
  • They do NOT specify HOW* it is achieved (TWTA, SSA with a Parabolic dish with a dipole, a Flat Panel, or a Multi-Array, etc).

*By not specifying HOW, the Commission allows and

encourages industry to innovate.

microwave transmission reception system
Microwave Transmission/Reception System

A Microwave Transmission/Reception System Consists of two pieces:

  • A Signal Generator/Receiver (Transceiver)
  • An Antenna consisting of two pieces
    • i. Primary Element - determines the RPE
    • ii. Microwave radiator(s) such as a dipole or horn, etc.

Antenna System Regulations

The location and radiation pattern of an antenna system’s radiator(s) has never been specified and has never been a cause of concern, because it is the level of Interfering signal “I” arriving at the victim receiver from the interfering system in its totality that is used for coordination interference calculations, C/I and T/I

(This applies to any type of antenna system and path)

smart antenna with distributed radiators
Smart Antenna with Distributed Radiators
  • A smart antenna with distributed radiators is an antenna system that combines an antenna array with a digital-processing capability to transmit in an adaptive spatially sensitive manner so as to always maintain the Interference at the Victim receiver(s) input from any Distributed Radiating Element ( IDRE ) less than the coordinating Interference ( I ).

Therefore, the interference signal IDRE is not a cause of concern because it is the level of Interfering signal I that is dominating the coordination interference calculations, C/I and T/I .
