Samsung and Anritsu Demo LTE Broadcast Services (eMBMS)

Samsung Electronics demonstrated clear reception capabilities of LTE Broadcast services using evolved Multimedia Broadcast Multicast Service (eMBMS) technology. 

 Samsung used Anritsu's Rapid Test Designer (RTD) and MD8430A to simulate the LTE network environment. The Samsung engineers were able to create the eMBMS demonstration using RTD's graphical script design to drive the execution of the test simulation on an Anritsu MD8430A LTE signaling tester.

eMBMS technology allows the LTE network infrastructure to be used for the delivery of broadcast services, such as TV.

"Anritsu is delighted that Samsung, the world's largest cell phone maker, has selected the technology-leading capabilities of the RTD and MD8430A to verify the implementation of eMBMS capability in its devices," stated Kenji Tanaka, Executive Vice President at Anritsu. "Samsung's demonstration shows how Anritsu's RTD helps LTE device makers prove their leading-edge technology in an intensely competitive market where reducing the product launch cycle time is critical to success."

"We have used Anritsu test equipment from the very beginning of our LTE development programs," said Inyup Kang, Executive Vice President at Samsung Electronics. "Anritsu's RTD and MD8430A have made a significant contribution to our leading position in the LTE device market." 03-Aug-12

U.S. Opposes Changes to International Telecommunications Regulations

The U.S. State Department has submitted its first group of proposals to the World Conference on International Telecommunications (WCIT), which will be held at the end of this year in Dubai.

 WCIT intends to review and potentially revise the treaty-level International Telecommunications Regulations (ITRs), which govern the flow of traffic between nations and which have not been amended since 1988.

The U.S. proposals include:
  • Minimal changes to the preamble of the ITRs;
  • Alignment of the definitions in the ITRs with those in the ITU Constitution and Convention, including no change to the definitions of telecommunications and international telecommunications service;
  • Maintaining the voluntary nature of compliance with ITU-T Recommendations;
  • Continuing to apply the ITRs only to recognized operating agencies or RoAs; i.e., the ITRs’ scope should not be expanded to address other operating agencies that are not involved in the provision of authorized or licensed international telecommunications services to the public; and
  • Revisions of Article 6 to affirm the role played by market competition and commercially negotiated agreements for exchanging international telecommunication traffic.
The U.S. WCIT Head of Delegation, Ambassador Terry Kramer, stated: “The ITRs have served well as a foundation for growth in the international market,” Ambassador Kramer said. “We want to preserve the flexibility contained in the current ITRs, which has helped create the conditions for rapid evolution of telecommunications technologies and markets around the world... We will not support any effort to broaden the scope of the ITRs to facilitate any censorship of content or blocking the free flow of information and ideas. The United States also believes that the existing multi-stakeholder institutions, incorporating industry and civil society, have functioned effectively and will continue to ensure the health and growth of the Internet and all of its benefits.”

Intelsat 20 Successfully Launched

 Intelsat 20 satellite was successfully launched by an Ariane 5 rocket from Kourou, French Guiana.

 Built by Space Systems/Loral, Intelsat 20 will provide C-band and Ku-band for DTH television, cellular backhaul and VSAT services. The Intelsat 20 video neighborhood provides premium programming that is carried by the top Indian cable MSOs and DTH operators, reaching more than an estimated 90 million Pay-TV subscribers across India. Intelsat 20 also hosts the largest DTH platform in Africa.

Intelsat 20 will replace Intelsat 7 and Intelsat 10 at 68.5° East, and is expected to have a service life of more than 18 years. 

CC to Update Cable TV Technical Rules

The FCC is proposing to modernize and reform its cable television technical rules, many of which extend back to the analog era. The FCC said its goal is to permit the industry to utilize their existing spectrum more efficiently, while also ensuring good quality signals for digital cable customers . The proposed revision will streamline compliance for operators of digital cable systems and update cable signal leakage rules. 

FCC Adopts Wireless Backhaul Rules

The FCC formally adopted new rules governing use of microwave frequencies for wireless backhaul. The action is aimed at speeding the rollout of 4G networks.

Specifically, the new rules permit fixed microwave operators to use smaller antennas in certain microwave bands, which can result in significant cost savings to operators. The Rural Microwave Flexibility Policy adopted today will provide increased opportunities for broadband deployment in rural areas, increasing coverage and reducing cost.

The FCC also updated existing microwave efficiency standards to reflect modern digital technologies. 03-Aug-12

Huawei Develops LTE-Advanced Multi-Stream Aggregation for Cell Edge

Huawei has contributed a new LTE-Advanced Multi-Stream Aggregation (MSA) technology to the 3GPP LTE-Advanced standards to boost data rates at a cell's edge. The technology coordinates macro cells to improve user data rates at the cell's edge and also between heterogeneous networking scenarios to improve peak rates and simplify mobile management to ensure a consistent user experience.

Huawei said its MSA technology reduces the number of handovers, lowering device power transmission and increasing device standby time. The company calculates that the technology will improve system performance at the cell's edge by almost 30%. The multi-stream aggregation is especially suitable for macro-micro HetNets. In hotspot area, macro cells provide basic LTE coverage while the micro cells provides capacity enhancement. The use of MSA technology allows users to receive controlled signaling from macro cells and services from best quality HetNet cell. Users at any location within the network can then enjoy fast and stable data services with ultra broadband, zero waiting and ubiquitous connectivity. MSA technology brings users high speeds and high quality as well as a simple service experience.

Huawei noted that it has contributed 293 core standards to the 3GPP LTE/LTE-Advanced standardization process. 

Huawei Tests LTE Circuit Switched Fallback with Qualcomm Snapdragon

Huawei and Qualcomm have completed an LTE FDD flash CSFB (Circuit Switched Fallback) voice call to UMTS using R9 protocol and Qualcomm's latest Snapdragon S4 processor, the MSM8960, during a series of optimization tests.

The companies reported that the tests, based on the flash CSFB voice solution for the R9 protocol, resulted in lower call setup latency than that of the R8 protocol, and very close to that of a native UMTS voice call. During the CSFB testing, which also included LTE TDD calls, good call setup times were seen for both UMTS and GSM.

The joint CSFB testing was part of an ongoing cooperation between Huawei and Qualcomm on interoperability testing and optimization involving GSM/UMTS/LTE TDD/FDD technologies.

Huawei noted that its LTE CSFB solution has been commercially deployed in the Middle East, Asia Pacific, Europe and other regions, allowing users to enjoy fast LTE data services and improved voice services. 02-Aug-12
