  • Recently, wireless technology that have been studied and developed is broadband wireless access technology with IEEE 802.16d standard, or well-known as WIMAX. It is an evolution of prior broadband wireless technology, Wi-Fi. The technology is designed to provide non-LOS condition and use adaptive modulation technique such as QPSK, BPSK, 16QAM, and 64QAM. IEEE 802.16d standard can possibly make internet wireless connection reach out for 75 Mbps speed or 35 times faster than copper wire line (ADSL). To support dynamic and good modulation scheme, IEEE 806.16d adopts the technology which able to increase coverage use mesh topology and smart antenna technology. With good scheme modulation, IEEE 802.16d affords large throughput in long distance and high spectra efficiency level. This thesis will analyze broadband wireless access technology with IEEE 802.16d standard. Performance parameters used are link budget estimation (RSL), signal quality (SNR), upload and download speed. The result of this thesis showed that RSL and SNR in each point correspond to different environmental conditions, the distance to the SS and BS type of modulation used. SNR is determined by many factors such as the environment propagation between BS and SSs, if condition LOS or directly there is no barrier (obstacle) then the greater the SNR. For most there is a nice SNR emphasis BTS PTC i.e. 36,77 dB due to condition of most small SNR and LOS obtained provide Aston Hotel Palembang that SNR of 0.27 dB because signal experienced a handover.
