The Research Of Selection Of Wireless Access Technology For Shanghai DX Company

Wireless access technology is one of the most important moderntelecommunications technologies. Wireless access technologies havedifferent types. Every one has its own characteristic. It was an urgentproblem for Shanghai DX Company to use which type of wireless accesstechnology for building wireless access network after it achieved the3Gservice operation qualification. Techno-economic method was used to studythis problem from government policies’, technical, and economic aspect.First, the current situation and wireless access technologies that could beused by Shanghai DX Company was analyzed. Secondly, the governmentregulation policy was analyzed. The government regulation policy decidedthat Shanghai DX Company could only use WLAN access technology andCDMA2000/EVDO access technology. Thirdly, WLAN access technologyand CDMA2000/EVDO access technology was analyzed in detail. Thecombination solution of WLAN and CDMA2000/EVDO access technology is the best choice to Shanghai DX Company for wireless access technologyconsidering that the geographical conditions and population density ofShanghai and current network situation. Lastly, the economic analysis to thecombination solution was executed according to the principle of engineeringeconomics using the method of project analysis. The analysis showed that theproject was feasible based on payback period, net present value and internalrate of return.Through the analysis of current situation, government regulation policy,technical aspect and economic aspect, it was concluded that the combinationsolution of WLAN and CDMA2000/EVDO access technology was feasiblefor Shanghai DX Company.
