I In early 2007, PT. Bakrie Telcom as a provider of fixed wireless access telephone service network CDMA2000-1x, specifically in the JABOTABEK area (Jakarta, Bogor, Tangerang and Bekasi), has been equipped with a WiMode modem of the SXC-108 type with a data rate of up to 153.6 kbps. The service quality indicator of this network can be measured technically and non-technically. Technical measurement is to measure things related to the performance of network system parameters, and non-technical ones that are not related to the performance of the network system parameters. This study aims to determine the extent to which the main performance of the mobile internet access network and customer perceptions of operator services. The object of the research is the main performance of the internet access network including bandwidth, throughput, response time and data loss, and customer perceptions of coverage area, drop calls and company performance. Locations of observations and surveys were carried out in the Jakarta and Pemangah areas (Bekasi, Depok and Tangerang).The results of the study show that: 1 the average bandwidth in the oltior area of ​​Jakarta is quite adequate (> 63%) and in the buffer zone it is poor (< 44, 4%); 2) the average throughput in Jakarta* is inadequate (54, 5%) and Jakarta** is adequate (71, 3 %), and in Buffer it is classified as poor (< 34. 8%); 3) the average response time in all regions is classified as poor (> 2 seconds); 4) The average data loss in the Jakarta area is in very good category (<1, 43%), and in the Pemangah area it is good (< 4.29%); 5) The relationship between parameters has a correlation with each other, and between throughput and bandwidth has a linear relationship. Respondents' perception of a) coverage area is relatively poor; b) drop calls are relatively good; c) fairly good rates; and d) the company's performance is categorized as quite good.
