TMCNet: 3G Americas Publishes Report on Key Advantages of LTE TDD for Unpaired Spectrum in the Americas

3G Americas Publishes Report on Key Advantages of LTE TDD for Unpaired Spectrum in the Americas

(Market Wire Via Acquire Media NewsEdge) BELLEVUE, WA -- (MARKET WIRE) -- 11/19/09 -- 3G Americas, a wireless industry trade association representing the GSM family of technologies including LTE, today announced that it has published an educational white paper titled, "3GPP LTE for TDD Spectrum in the Americas." The report provides a top-level overview on the considerations for deployment of Long Term Evolution ( LTE) in Time Division Duplex (TDD) technology spectrum in the Americas and recommends LTE TDD as a mobile broadband solution to utilize valuable TDD spectrum assets in the region.

"LTE TDD provides a tremendous solution for utilizing the large swaths of fragmented and unpaired TDD spectrum that are present throughout the Americas region," said Chris Pearson, President of 3G Americas. "LTE TDD can be a complementary solution to LTE FDD and serve society's demands for a global mobile broadband technology." The white paper explains the technical mechanism in which LTE TDD (also known as TD-LTE) and Time Division Synchronous Code Division Multiple Access (TD-SCDMA), a 3rd Generation Partnership Project (3GPP) third generation technology deployed in China, are smartly designed with the ability to operate together with great harmonization and efficiency. LTE TDD is a natural migration for TD-SCDMA operators. The technical synergy between LTE TDD and TD-SCDMA operators will thus increase the economies of scale for LTE TDD operators throughout the world.

Although operators are making plans for the deployment of LTE Frequency Division Duplex (FDD) technology, the white paper emphasizes that operators, regulators, license holders and investors must strongly consider the significant opportunities behind deployment of LTE in fragmented TDD spectrum as a mobile broadband solution that can serve the communication needs and demands of the marketplace.

Additionally, the report highlights that as mobile broadband is becoming ubiquitous throughout the Americas and the Internet generation is growing more accustomed to having broadband access everywhere, technology usage is exploding and, thus, is putting a tremendous strain on already well-utilized networks and spectrum. "3GPP LTE for TDD Spectrum in the Americas" focuses on the LTE ecosystem and how operators are working to meet this increasing demand for mobile broadband services.

"LTE TDD is often overlooked as a mobile broadband solution," Pearson said.

"Operators and regulators must consider all of their options in meeting mobile broadband demands." Erasmo Rojas, Director of Latin America and the Caribbean, added, "Specifically, this is a critical time in the industry for regulators in the Latin American region to carefully plan TDD spectrum allocations ensuring that technologies do not cause undue interference while at the same time making certain that the spectrum is consistent with global TDD allocations to take advantage of the economies of scale." The LTE ecosystem supports both FDD and TDD operation, offering operators flexibility to match their existing networks, spectrum and business objectives for mobile broadband and multimedia services. Fifteen paired (for FDD operation) and eight unpaired (for TDD operation) spectrum bands have already been identified by the 3GPP for LTE. This means an operator can introduce LTE in new spectrum bands.

The white paper, "3GPP LTE for TDD Spectrum in the Americas," was written collaboratively by members of 3G Americas and is available for free download on the 3G Americas website at www.3gamericas.org.

Featured White Papers

  • Seven Best Practices for Speech Analytics: Speech analytics is valuable for identifying issues in the contact center. However, limiting its use to the contact center only considers a portion of all customer interactions and subsequently only reveals a small part of the voice of the customer. This paper discusses how organizations can optimize their Speech Analytics implementation strategy to realize the promise of this exciting technology.
  • Understanding the Voice of the Customer: Today's contact centers involve a sea of information that must be captured, processed, and distributed on a daily basis. Effective use of this information enables companies to remain competitive in an increasingly aggressive and customer centric marketplace. An overwhelming percentage of the information that circulates in a contact center's audio recordings, documents, web pages, and emails is unstructured in that it resides outside of a normal structured database and cannot be managed efficiently. These unstructured items contain valuable information, yet this information historically has been difficult to organize, categorize, and access.
