| Popis: | 97 Technology will help create new behavior of utility among human beings, and people who used to surf on network are been confined to home or network coffee-shop. Though there have been outdoor net-surfing technology and service promotion for GPRS or WiFly in the last 5 years, the speed and stability provided can hardly match the needs of user for net-surfing, and it is why it has not yet created successful business model. However, with the advance of technology, the development of 3G mobile broadband network has gradually become matured as the speed is kept upgrading and price-tag of terminal equipment dropping. Users seem to have discovered the life model changed along with the new technology so that the number of users is growing with the new high. Therefore, telecom entrepreneurs have then invested a great deal of capital to expand construction of network and enlarge their marketing business. However, the fee of mobile net-surfing has inherited previous habit and expectation of fixed-rate of “All you can eat,” ending up with serious imbalance between “quantity” and “price,” and the imbalance has seriously affected the income of telecom entrepreneurs. As such, it has become most critical for the control of network cost as how they conserve as much as they can while retaining high volume of data when they are striving wholeheartedly to win over more clients and maintain turnover. For private mobile telecom entrepreneur whose costs of backhaul (transmission between each of the base stations and mainframe room) are found less abundant than Chung Hwa Telecom, given with sufficient fundamental transmission infrastructure, it is, without doubt, that out-of-control cost will become one of the most important links. Thus, this study will focus on such problem for resolution, and conduct a series of investigation and analysis. For the time being, alternatives of resolution for backhaul are preliminarily found with “ Self-built network,” “ Rental optic-fiber,” “ Cooperation with cable TV,” “ Unboundled Local Loop” “ Establishment of microwave,” “ MiWAX technology,” and “ Femtocell business model.” Nonetheless, all of these resolutions have to be dealt from perspective of regulation, cost, maintenance, accessory value, and timeliness and so as background and conditions as capital, strategy, and existing resources of the entrepreneurs for comprehensive analysis. The reason that mobile telecom entrepreneurs is successful after the privatization of telecom in Taiwan, aside from encouragement form legal provisions and regulations, high demand of users, and matured and stable technology, can be largely attributed to the relatively low reliance on existing infrastructure resource. On the contrary, fixed-net business that relies high on existing infrastructure resource has turned into a case of failure as under the monopoly by Chung Hwa Telecom for local loop. However, the demand for wireless broadband has intensified their reliance on such resources, and so the approach of private telecom entrepreneurs should work through the force of regulation for cooperation so as to compel the vested interest can open its subscriber local loop or optic-fiber with reasonable manner and price for rental, helping to avoid the scenario of monopoly for telecom environment in Taiwan years alter. Furthermore, for entrepreneurs with economic scale, they should, under trend of digital convergence, actively work with existing cable TV entrepreneurs on the construction of common transmission so as to multiple their investment benefit and avoid waste of fundamental network resource after future merge or cooperation. Besides, for new entrepreneurs or those that are found with economic scale, it is definite beneficial to them to break loose of fixed rate of market for transmission, and they should, as well, make use of microwave and WiMAX technology to focus on specific area for utilization. The analysis of advantage and disadvantage in this case is based on the understanding of current conditions of telecom industry of Taiwan, and then technical literatures and analysis of various projects are collected to appreciate present deployment situation and their advantages and disadvantages. Next, present status of the industry is garnered so as to well master the development among trade peers and other trades in Taiwan market, or the conditions of utility for each technology as used in Taiwan for now. Afterwards, technical literatures and the collected information regarding current status of Taiwan market can be placed for cross-analysis, attempting to find the model of feasible project can obtained, and it is hoped that it can benefit the resolution of backhaul for each of the mobile broadband entrepreneurs. |
