WiMax wireless goengdaeyeok failures of the past will be able to catch up?
■ Broadband Wireless (broadband wireless) in the late 1990s the LMDS / MMDS fixed broadband wireless services, but greater attention to the market, a profitable business model as failing to excavate, and eventually 'DSL / cable modem service does not reach the service shaded area for the niche market technology / service 'by a tumble, a failed business case is recorded in history as one of
■ failed to be the main causes for broadband wireless experts 'immature technology', 'absence of standards', 'mihwakbo economies of scale', 'absence of a profitable business model' and the intellectual and accordingly the IEEE 802.16 TG-related companies based on standardization work in progress, while broadband wireless, wireless LAN, a decisive contribution to the popularization sikineunde Wi-Fi Alliance had decided to benchmark the model, and in 2001 WiMax (Worldwide Interoperability for Microwave Access) forum to promote the industry group jojikham
■ 2004 December, Intel, Cisco, Lucent, Siemens Mobile, etc. 181 leading semiconductor / equipment / service providers to join the WiMax Forum members, especially the largest semiconductor company, Intel's WiMax's history, fully sponsored and Unlike a more positive direction as the market unfold gidaedoem
WiMax market in the short term outlook uncertain
■ Intel despite aggressive move, WiMax will ultimately not complete a standardized form, the initial market is expected to suffer
■ completed to date include 802.16-2004 standard 'wired high-speed Internet service, an alternative', 'wireless LAN or cellular backhaul "to provide such services, which increases the current equipment prices DSL • • hotspot service in direct competition with cable modem The market potential is difficult to backhaul services is not large scale
■ In addition, 802.16d upgradeable to 802.16e standard is not shown to the past, LMDS / MMDS as service providers have experienced a failure, then the future whether to upgrade their investment in opaque 802.16d is likely to be avoided, especially the incumbent service providers, if not inevitable and potentially to compete with cable modem, DSL • the introduction of new technologies will not
■ Therefore, standardization is complete, 802.16e WiMax equipment market is being released to market commercial products, equipment prices are expected to be reduced to an acceptable level, or 2008 through 2009 is expected to remain in a niche market
WiMax service "backhaul" → "access" → "mobile" evolved as expected
■ WiMax is expected to be introduced is the first sector is currently using primarily T1 leased lines to transmit traffic 'wireless LAN hotspot backhaul as expected
Hotspot backhaul services market is going to be a limited market opportunities
■ degree of approximately $ 20,000 WiMax (Rev D) is one of 45 stations on a T1 line can deliver, and service providers that connect to a WiMax hotspot with T1 per line for the low price of about 300 to 400 U.S. dollars to provide services may appear to be 18 months or so expected to be able to recover investment funds
■ The number of hotspots, but the world in 2008 estimated that 23 to 260,000 jeongdoil site, so all of these hotspots backhaul WiMax backhaul hotspots even if replaced by a potential market size is expected to be limited
■ Some small companies instead of expensive leased lines to an existing wired the possibility of WiMax services available, but large corporations and financial institutions, etc. of the wireless medium to low security and reliability concerns, there will not be positive that the introduction
WiMax is a DSL, cable modem, is less likely to be a substitute for
■ The $ 500 price of the subscriber device to the standardization and economies of scale if we lowered significantly to less than $ 200, WiMax, such as a cable modem and DSL • High-speed Internet service to compete with existing substitutes to emerge as a possibility, but high-speed Internet penetration is low and difficult to spread geographically wired solutions in China, India, South America and other developing nations are expected to be distributed mainly in the market, DSL • Cable modem service is already widespread in the developed countries for the niche services in rural areas than urban expected to limit market opportunities
■ WiMax (Rev D) the DSL • Cable modem and existing high-speed Internet services and compete effectively in order to service providers at a lower cost than the frequency license can be acquired to be, and that service the country (region) of the high-speed Internet penetration relatively low, and to provide nationwide service to be backed up by strong financial capabilities, they must meet several conditions, such as seems possible, depending on the nature of the regional WiMax services market penetration is expected to exist a difference
■ Thus, at least in the short term WiMax services compete directly with existing high-speed Internet services rather than services is likely to be used as a supplementary nature, high-speed Internet service penetration is low or DSL / cable modem service in many countries more than shaded area market opportunities that you will get, gidaedoem
Early implementation of 802.16e WiMax standardization and commercial success of future performance and prospects
■ WiMax to demonstrate the true value when the 802.16e mobile WiMax standard version has been released commercially in the services market is expected to be implemented since 2008, mainly laptops, PDA and mobile PC is expected to be implemented in
■ long-term viability of WiMax as a high-speed Internet service in order to improve the existing wired high-speed Internet access and to differentiate the 'portability (portability) or mobility (mobility)' function is necessary
■ Park's Associates a high-speed Internet service available in the U.S. 3370 household survey conducted according to the results, the respondents estimated 62 percent of the mobile Internet (portable internet) have an interest in, and 5% transmission rate and price If the same is willing to move the mobile Internet services that respond
■ Thus, both WiMax and early MobileFi standardization and low cost commodity products to market in a timely manner to provide market timing is the key to gauge the success or failure is expected to be
MobileFi WiMax and will not be a threat to the WCDMA/CDMA2000
■ WiMax existing mobile communication technology and practical in order to compete 802.16e standard, based on the VoIP voice service functionality must be provided to the mobile version of WiMax full-fledged commercialization at the earliest since 2008, is expected to be it, this by the time WCDMA For HSDPA, CDMA2000 EV-DV upgrade to a proceeding is already there, and mobile communication technologies, WiMax and similar levels of high-speed data services is expected to be able to provide
■ cost, size, power, VoIP, and because of technical problems, to implement WiMax in the mobile communication terminal is expected to be minimal since 2008.
■ WiMax Wi-Fi hotspot service now have the potential to replace, but currently more expensive equipment, the same as Wi-Fi hotspot services to support the WiMax coverage area 2.9 times the cost, so decrease significantly if the cost of building supplementary rather than a substitute for the time being Wi-Fi (backhaul) expected to be used as
Mass-market technologies add VoIP capabilities to take shape, and low-cost essential artists
■ VoIP voice service does not support data-only WiMax service popularized scenario at present, the reality is almost not shown and, therefore, 'VoIP over Wireless' feature to be included is currently satisfactory call quality is reached, not technology maturity to increase prerequisite
■ The pre-standard WiMax subscriber equipment is about $ 500, here mobile and VoIP features to be added, if the price is more evident nopahjige and future shipments increased by at least $ 250 or more even if prices drop in the price expected to incur
■ Therefore, Wi-Fi, at least to get the same popularity today's Wi-Fi equipment cost $ 100 to a level similar to lower the mass market is a prerequisite for establishing technology can be
Domestic WiBro mobile Internet service activation required for VoIP functionality
■ UBS Securities Inc., the recent 'VoIP services without the ability to provide the data if the' and 'VoIP, data services, if provided with the "divided into two scenarios: domestic WiBro mobile Internet services market, which is expected, the data services If you are providing WiBro service in 2010 the number of subscribers, 2.5 million people (5.1% penetration rate compared to the total population), voice and data services, if provided with WiBro services in 2010 the number of subscribers, 7.1 million people (14.5% penetration rate compared to the total population) estimates that each
■ The number of subscribers of KT netseupat hat absurdly original expectations remain at a level of 400,000 people, if we consider that, to the development of mobile internet services to mass market voice services is essential yeogyeojim
■ Mobile phones with Internet service initially meoltimodeuhyeong 'Mobile Internet + mobile communications' in the form of bundled services of voice services is expected to be available, from mobile Internet services supporting VoIP over Wireless voice quality associated with the various technical We're going to be able to solve problems should be
The outlook is still pessimistic 802.20/MobileFi
■ 802.20/MobileFi 100km at speeds lower than the portability / mobility to support up to 250km high-speed WiMax and other technologies that support mobility, but standardization work progressed slowly until after it expected to close in 2007 at the earliest
■ WiMax is also Cisco, Intel, including leading semiconductor / equipment / service providers to support, but, 802.20/MobileFi the state and who do not, because of this some of the industry officials to standardize the final 802.20/MobileFi whether they can proceed smoothly with skepticism, and diarrhea, even if it is complete, standardized parts of 802.16e standard may be reduced and expressed the opinion that
■ MobileFi The biggest advantage of cellular technology as well as to support the mobility of high-speed up to 250km and a maximum cell radius of 10km from the 802.16e subscribers as well as the transmission speed of 1-2Mbps Provide
■ 802.16e have a laptop or PDA at a low speed pedestrian or vehicle, if targeted at mobile users, MobileFi with the vehicle moving at high speed or high speed trains, and is targeted at users who may
■ 802.20/MobileFi standards development, even though the actual H / W and S / W development is expected to take a significant amount of time, therefore, to be implemented MobileFi since 2009 or 2010 expected to be
■ By the time he WCDMA/CDMA2000 technology with similar performance / service is expected to be upgraded, WiMax as well as a faster handoff performance would be evolved, so the survival of premature standardization and commercialization of technology, a difference in whether will be expected to
