China Unicom Deploys High-Speed Agile Optical Network 40G Today – 100G Ready! CASE STUDY MARKET: Telecom operator REGION: CHINA COMPANY: CHINA Unicom CHINA UNICOM DEPLOYS HIGH-SPEED AGILE OPTICAL NETWORK 40G TODAY – 100G READY! China United Network Communications Group Co., Ltd (“China Unicom”) was established in 2009 as a result of the merger of former China Netcom and former China Unicom. At present, the Company is engaged in GSM and WCDMA cellular business in thirty-one provinces, municipalities and autonomous regions in China, the provision of fixed-line voice, broadband and other Internet-related services, information and communications technology services, business and data communications services, and other related telecommunication value- added businesses. As of the end of December 2012, the total subscribers of the Company’s mobile, local telephone and broadband businesses reached 395 million. China Unicom is among the world’s Top 500 companies in terms of revenue, and ranked in the top of the world’s leading telecom operators in terms of its customer base and market capitalization of its listed company. It is the only Chinese Telecom operator listed on the stock exchanges in New York, Hong Kong, and Shanghai.

  • Share Swap Between Telefónica and China Unicom
    La Dirección Estratégica de la Empresa. Teoría y Aplicaciones L.A. Guerras y J.E. Navas Thomson-Civitas, 2007, 4th edition www.guerrasynavas.com SHARE SWAP BETWEEN TELEFÓNICA AND CHINA UNICOM Miriam Delgado Verde Universidad Complutense de Madrid In 2005, Telefónica and China Unicom entered into a strategic alliance with the aim to operate jointly in the telecommunications industry. Initially, it took the form of a minority holding by the Spanish company in its Far Eastern counterpart when Telefónica purchased 5.38% of the Chinese operator’s capital. This initial operation was reinforced in September 2009 with a share swap between both companies, whereby Telefónica’s investment rose to 8.06% of China Unicom’s capital, whereas the latter acquired 0.9% of the Spanish telephone company. Through this new operation, Telefónica acquired a further 694 million shares, up to the aforementioned percentage, whilst China Unicom undertook to acquire 40.7 million shares in the Spanish company, which meant an investment by each party of one billion dollars (around 700 million euros at the prevailing rate of exchange). The partners agreed to keep possession of the shares for at least a year, although the agreement included joint operations over the following three years, unless either one of the parties should discharge the contract with six months’ prior notice. These joint operations included shared procurement, the development of common platforms for mobile phone services and the provision of services to multinational customers. One of the agreement’s clauses laid down a restriction on any investment in the share capital of each other’s rival companies.

    India and China: A Comparative Analysis of Mobile Phones in Agriculture By C2014 Prashanthi Bonthu Submitted to the graduate degree program in Global and International Studies and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Master of Arts. ________________________________ Chairperson Professor Eric Hanley ________________________________ Committee Member Professor Darlene Budd ________________________________ Committee Member Professor John James Kennedy Date Defended: Feb 3rd , 2014 The Thesis Committee for Prashanthi Bonthu certifies that this is the approved version of the following thesis: India and China: A Comparative Analysis of Mobile Phones in Agriculture ________________________________ Chairperson Professor Eric Hanley Date approved: Feb 3, 2014 ii Abstract In 2010, China and India were named the first and second largest mobile phone markets in the world based on their number of subscribers. India and China have focused on extending their telecommunication services into rural areas for socio-economic benefits. Both countries liberalized and privatized the industry under different political regimes utilizing different strategies. The aim of this thesis is to examine the collaborative efforts of public and private agencies in India and the role they do in disseminating information to farmers through mobile phones when compared to the government agencies in China that have been created to share that information in order to determine which program is more effective. To answer this question, the thesis compares Indian and Chinese policies and programs enacted to encourage sales and use of mobile phones in the agricultural sector to increase efficiency and encourage growth. As free market principles and private for-profit corporations are generally more efficient than government agencies, this thesis hypothesizes that the policies and development initiatives taken by the Indian government are more successful in disseminating information than the government agency approach followed by China.

  • Key Issues and Comment TIP’S Packet Transport Group Issues New Rfis in Push Towards Open Platforms
    Volume 17, issue 32 March 19-25 2020 Copyright Rethink Technology Research 2020 Key Issues and Comment TIP’s packet transport group issues new RFIs in push towards open platforms One of the most important contributions that the Telecom Infra Project (TIP) is making to the push towards fully open, interoperable networks is to provide real world frameworks for deploying systems based on open specifications like those of the O-RAN Alliance. Gathering and distilling detailed operator requirements, defining processes, facilitating reference designs, and enabling requests for information (RFIs) are just some examples of the valuable, pragmatic developments which are emerging from TIP’s working groups, and which will make it more realistic and less risky for operators to start embarking on open networks. We have already seen a series of RFIs and RFQs (request for quotes) in the small cell and 4G/5G RAN area, led by Vodafone and Telefo nica. Now those two operators are joined by Deutsche Telekom, NTT Communications and Telia in issuing an RFI to transport network suppliers – traditional and new – to kickstart development of commercial optical systems based on disaggregated and open architectures. The requirements for this technology have been synthesized from the activities of a pro- ject group codenamed Phoenix, which includes these five operators and other partici- pants. Now vendors will be asked to submit information about products which could sup- port those requirements while being open and interoperable. The RFI will be designed to "evaluate industry readiness in upcoming months, with the target to have specification-compliant solutions ready for commercial deployments in the first half of 2021," according to a blog written by Ví ctor Lo pez A lvarez, a technology spe- cialist at Telefo nica, published by TIP last week.
