4G/5Gのベンチマークパフォーマンス調査と標準化に向けた取り組みに焦点を絞り込んだ情報サービス Signals Ahead - Newsletter Subscription: Focused on 4G/5G Benchmarking Performance Studies and Standardization Activities
出版日: 年12回 年間契約型情報サービス ページ情報: 英文
概要

当サービスは、サービスは、米国の市場調査/コンサルティングサービスプロバイダーであるSignals Research Group (SRG) が提供するものであり、12ヶ月間で12本のSignals Aheadと4~6本のSignals Flashが発行されます。

Signals Aheadは、技術に重点を置いた情報を提供するもので、ベンチマーク調査と3GPPでの標準化に向けた取り組みが主な焦点となります。ベンチマーク調査には、新たなネットワークやデバイスの機能、技術、サービス、アプリケーションの詳細なテストや分析が盛り込まれます。これらの調査は極めて詳細なものですが、レポートは技術畑以外の方でも分かりやすい内容になっています。またレポートの発行に加え、ベンチマークテストに関する専門知識と高い評価を活かして、企業の多様なニーズに個別に対応するサービスも提供しています。調査対象となっているのは、インフラストラクチャ技術の主要なプロバイダー、チップセットやデバイスのメーカー、移動体通信事業者、ソーシャルネットワーキング企業などです。

Signals Aheadでは、世界各国で行った調査に基づき、さまざまな技術に関する業界初の独立したパフォーマンス分析を過去数年にわたって提供してきました。これまでに発行された業界初の主なレポートを紹介します。

目次

Signals Research Group (SRG) is a US-based research consultancy that publishes its research in a subscription-based product called Signals Ahead. A subscription includes 12 Signals Ahead reports and 4-6 Signals Flash reports over a period of approximately 12 months.

Signals Ahead provides technology-focused information and is primarily focused on benchmark studies and 3GPP standardization activities. The benchmark studies involve detailed testing and analysis of new network or device features as well as new technologies, services, and applications. Although these studies are very in-depth, the reports are written in a style that is suitable for non-technical individuals. In addition to providing the Signals Ahead publication, SRG leverages its expertise and reputation in the field of benchmark testing to engage companies on an individual basis. Sample companies include many of the major infrastructure suppliers, chipset and device companies, as well as mobile operators and social networking companies.

Over the last few years, Signals Ahead has provided the industry's first truly independent performance analysis of multiple technologies, based on studies performed around the world.

Sample industry firsts include:

  • 5G Millimeter Wave (Verizon Wireless) - February 2018
  • 5G Fixed Wireless (Verizon Wireless) - October 2018
  • Massive MIMO (Sprint) - November 2018
  • LAA (AT&T) - January 2018
  • 4-carrier Carrier Aggregation (Telstra) - April 2017
  • 4x4 MIMO (T-Mobile) - January 2017
  • Uplink 64-QAM (SK Telecom) - September 2016
  • 256-QAM (Telstra) - May 2016
  • FDD + TDD Carrier Aggregation (Optus) - March 2016
  • 8T8R (Sprint) - May 2015
  • IR-94 Video Telephony (AT&T) - March 2015
  • 3-carrier Carrier Aggregation (LG U+) - May 2015
  • LTE (TeliaSonera) - February 2010
  • DC-HSDPA (Telstra) - January 2011
  • Category 6 LTE (SK Telecom) - September 2014
  • LTE TDD versus LTE FDD (Softbank) - September 2013
  • HSPA+ (Telstra) - July 2009
  • VoLTE (AT&T) - August 2014
  • 2x2 MIMO (T-Mobile) - August 2013

In the coming year, the Signals Ahead publication will continue to focus on benchmark studies and 5G standardization activities. Sample research that is planned, includes:

  • 3GPP-based IoT benchmark studies - field and lab
  • 5G NR millimeter wave benchmark studies - 28 GHz and 39 GHz
  • 5G NR sub-6 GHz benchmark studies - 2.5 GHz, 3.5 GHz and sub 2 GHz (last one not likely until late 2019)
  • 2 Gbps LTE
  • CBRS
  • LTE-Broadcast versus unicast
  • Small cell optimization
  • UL-CoMP
  • MU-MIMO, Part 2 - 5G NR and LTE
  • 3GPP standardization updates - published quarterly

Signals Flash provides near-real-time feedback and analysis on industry events or quick thoughts from our benchmark studies. Over the last year, the Signals Flash reports have provided rapid insight on activities occurring during 3GPP standardization meetings as well as initial thoughts while testing 5G.
