增值竞争力服务勇当先--探索国内硬件防火墙市场之变

根据IDC近期公布的数据显示，中国硬件防火墙市场正在以61．3％的年复合增长率稳定、快速增长，2006年市场收入有望达到5．498亿美元，中国硬件防火墙市场的容量仍然巨大。但一个不争的事实是，该领域市场收入的增长率，却正在从2001年的166．7％下滑至2005年的48．8％，有专家预计，2006年的这一数字将出现47．7％的继续滑落。由此可以断言，随着国际防火墙市场从2005年开始出现负增长，中国也难逃市场饱和所带来的影响。

Printed antennas for dual-band GSM/DCS 1800 mobile handsets

The recent developments of dual-band dual-mode D-AMPS/AMPS mobile handsets and radiostations has increased pressure on GSM service providers to follow similar technology breakthroughs as a first step towards IMT2000. A frequency-agile device accommodating both GSM standard frequency bands would serve more than 25 million GSM subscribers, with expectations as high as 100 million subscribers by the year 2000. Novel dual-band printed bow-tie antenna elements developed for dual-mode GSM/DCS 1800 handsets are described     

China's new players [mobile phone handset manufacture]

The Chinese mobile communications market is looking very attractive to multinationals faced with market saturation in regions like Western Europe, where penetration is expected to top 80% in the next few years. The Xinhua state news agency reports that mobile communications took 46% of the total telecoms revenue worth $26.5bn in the first half of 2003, when 28.5 million people signed up for mobile services-more than took up fixed lines. In terms of penetration, fixed-line still leads with coverage of 19.4 %, but at 18.3 % mobile phones are catching up fast. Demand for handsets is huge, but tough competition from local firms means that foreign manufacturers hoping to cash in on the boom can't afford to be complacent. China's Ministry of Information Industry reported that in the first half of 2003 the country's 37 mobile phone manufacturers produced just over 82 million handsets. Nokia and Motorola still take the lion's share, but 25 local firms grabbed a significant proportion of the market, with the biggest now among the country's top handset vendors.     

Effect of a policy intervention on handset subsidies on the intention to change handsets and households’ expenses in mobile telecommunications

This study examined effect of a policy intervention that provides an upper limit for handset subsidies on users’ intention to change handset and households’ expenses on mobile telecommunications. The Korean government has prohibited mobile network providers from providing excessive subsidies for mobile handsets to attract subscribers since Nov. 2014 according to the mobile act. Using the exogenous variation, we estimate the impact of the policy on the intention to change handsets and expenses on handset installment, total mobile communications, and online content. The longitudinal data are from the 2014 to 2015 waves of the Korea Media Panel Survey. The mobile act lowered the predicted probability of switching handsets by 0.4% points. Moreover, the mobile act increased the predicted probability of any expense on handset installment by 7.5% points and had a significant impact on the amount of expenses on handset installment, with an increase of 7.8%. The mobile act lowered users’ willingness to switch handsets and increased spending on handset installment. This increased burden in handset installment might shrink the online content market, which has a large need for government support, as well as decrease consumers’ welfare. We assert that the policy intervention on handset subsidies is questionable with regard to both consumer welfare and the healthiness of the ICT ecosystem.

iGSM: VoIP service for mobile networks

This article proposes iGSM: a voice-over-IP value-added service for the mobile network. The iGSM service provides user mobility to subscribers, which allows them to use either GSM handsets or H.323 terminals (IP phones or PCs) to access telecommunications services. We describe how the iGSM registration, deregistration, and call delivery procedures can be implemented without modifying the GSM network. We study how the tromboning effect in the standard GSM system can be avoided when accessing the IP network. Then we investigate the misrouting problem caused by user mobility

Measurement of a Customer Satisfaction Index for Improvement of Mobile RFID Services in Korea

One of the ubiquitous technology fields that have received the most attention recently from technology communities worldwide is mobile radio frequency identification (RFID). Mobile handsets loaded with RFID readers enable the identification and retrieval of information on RFID tagged objects. In Korea, a variety of mobile RFID services are currently being piloted, and their commercial roll‐out looks imminent. The goal of this study is to propose, ahead of the commercial launch of mobile RFID services, a customer satisfaction index (CSI) model for this service category and to then measure the CSI to derive practical implications for their providers and pointers related to the improvement of service. A web survey was conducted on Korean mobile phone subscribers who had participated in a mobile RFID pilot program. Using the results of this survey, we tested the CSI model and its hypotheses by employing a partial least‐squares‐based structural equation model analysis and calculated the index. We further conducted an importance‐performance analysis in order to provide insights that may be useful for improving the quality of mobile RFID services.
