INTRODUCTION This document describes how to install the WN-100, Wireless LAN PCMCIA Card. Wireless LAN is local area networking without wires, which uses radio frequencies to transmit and receive data between PC’s or other network devices. Wireless LAN is able to configure independent networks and infrastructure networks. The former is suitable for small or temporary peer-to-peer configurations, and the later is offering fully distributed data connectivity via micro cells and roaming. 2. INSTALLATION 2.1 Check the Product Package Before starting installation, please make sure the package you purchased includes the following two items: 1) Wireless LAN PCMCIA Card. 2) CD-ROM (containing Driver/Utility, and User’s Manual). Please contact your vendor if anything is missing or damaged. 2.2 Meet the Minimum Requirements To install the Card successfully, your computer should meet the following minimum requirements: 1) A PCMCIA slot complying with Release 2.1 of the PCMCIA specification. 2) Windows 95, 98, Me, NT, 2000, or XP operating system. 3) Minimum 5 Mbytes free disk space for installing the driver and the utility program. 2.3 Install the Driver and Utility Prior to the installation, you have to make sure the Card is not inserted to the PCMCIA slot. Please place the supplied CD-ROM to the CD-ROM drive, running AirvastWireless_V1.1.2.exe. Then, the InstallShield will guide you to install appropriate driver and utility. 2.4 Insert the Card Insert the Wireless LAN PCMCIA Card into PC’s PCMCIA slot in the right direction, pushing it gently into position. The Card is designed for plug-and-play, which allows you to insert it to a PC no matter it is powered ON or OFF. 2.5 Operation and Configuration As soon as you insert the Card, it can operate with the factory default settings. However, you may configure the desired settings by clicking the icon of PRISM Wireless Settings at the task bar. CAUTION: To comply with the FCC RF exposure compliance requirements, a separation distance of at least 2.5cm must be maintained between the antenna of this device and all persons. No change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate this device.

Transmitter Description The ISL3873B transmitter is designed as a Direct Sequence Spread Spectrum Phase Shift Keying (DSSS PSK) modulator which is capable of handling data rates of up to 11Mbps (refer to AC and DC specifications). The various modes of the modulator are Differential Binary Phase Shift Keying (DBPSK) for 1Mbps, Differential Quaternary Phase Shift Keying (DQPSK) for 2Mbps, and Complementary Code Keying (CCK) for 5.5Mbps and 11Mbps. CCK is essentially a quadra-phase form of M-ARY Keying. A description of that modulation can be found in Chapter 5 of: “Telecommunications System Engineering”, by Lindsey and Simon, Prentiss Hall publishing. The formula for CCK can be found later in this datasheet. The implemented data rates using a clock rate of 44MHz are shown in Table 6 and the modulation schemes are indicated in Figure 13. The major functional blocks of the transmitter include a Processor Interface, Modulator, Data Scrambler, Preamble/Header Generator, TX Filter, AGC Control, and ADC and DAC circuits. The preamble is always transmitted as the DBPSK waveform while the header can be configured to be either DBPSK, or DQPSK,and data packetscan be configured forDBPSK, DQPSK, or CCK. The preamble is used by the receiver to achieve initial Pseudo Noise (PN) synchronization while the header includes the necessary data fields of the communications protocol to establish the physical layer link. The transmitter generates the synchronization preamble and header and knows when to make the DBPSK to DQPSK or CCK switchover, as required. For the 1 and 2Mbps modes, the transmitter accepts data from the external source, scrambles it, differentially encodes it as either DBPSK or DQPSK, and spreads it with the BPSK PN sequence. The baseband digital signals are then output to the external IF modulator. For the CCK modes, the transmitter inputs the data and partitions it into nibbles (4 bits) or bytes (8 bits). At 5.5Mbps, it uses four of those bits to select one of 16 complex spread sequences from a table of CCK sequences. Thus, there are 16 possible spread sequences to send, but only one is sent. This sequence is then modulated on the I and Q outputs. The initial phase reference for the data portion of the packet is the phase of the last bit of the header. At 11Mbps, one byte is used as above where 8 bits are used to select one of 256 spread sequences for a symbol. Bit rates for the ISL3873B are defined in Table 6. This table provides information on bit rates, data rates and symbol rates for an MCLK of 44MHz clock. Figure 13 shows the modulation schemes for the different bits rates. The modulator is completely independent from the demodulator, allowing the PRISM baseband processor to be used in full duplex operation. Header/Packet Description The ISL3873B is designed to handle packetized Direct Sequence Spread Spectrum (DSSS) data transmissions. The ISL3873B generates its own preamble and header information. It uses two packet preamble and header configurations. The first is backwards compatible with the existing IEEE 802.11-1997 1 and 2Mbps modes and the second is the optional shortened mode which maximizes throughput at the expense of compatibility with legacy equipment. In the long preamble mode, the device uses a synchronization preamble of 128 symbols along with a header that includes four fields. The preamble is all 1’s (before entering the scrambler) plus a Start Frame Delimiter (SFD). The actual transmitted pattern of the preamble is randomized by the scrambler. The preamble is always transmitted as a DBPSK waveform (1Mbps). The duration of the long preamble and header is 192s. In the short preamble mode, the modem uses a synchronization field of 56 zero symbols along with an SFD transmitted at 1Mbps. The short header is transmitted at the 2Mbps rate. The synchronization preamble is all 0’s to distinguish it from the long header mode and the short preamble SFD is the time reverse of the long preamble SFD. The duration of the short preamble and header is 96s. Start Frame Delimiter (SFD) Field (16 Bits) This field is used to establish the link frame timing. The ISL3873B will not declare a valid data packet, even if it PN acquires, unless it detects the SFD. The ISL3873B receiver auto-detects if the packet is long or short preamble and sets SFD time-out. The timer starts counting after initialization of the de-scrambler is complete. Header Field The header field is defined by four fields which are shown in Figure 14. These fields are Signal Field, Service Field, Length Field and CITT-CRC16 Field. They are further defined by the following: Signal Field (8 Bits) - This field indicates what data rate the data packet that follows the header will be. The ISL3873B receiver looks at the signal field to determine whether it needs to switch from DBPSK demodulation into DQPSK, or CCK demodulation at the end of the preamble and header fields. Service Field (8 Bits) - The MSBofthisfield is used to indicate the correct length when the length field value is ambiguous at 11Mbps. See IEEE STD 802.11 for definition of the other bits. Bit 2 is used by the ISL3873B to indicate that the carrier reference and the bit timing references are derived from the same oscillator (locked oscillators). Length Field (16 Bits) - This field indicates the number of microseconds it will take to transmit the payload data (PSDU). The external controller (MAC) will check the length field in determining when it needs to de-assert RX_PE. CCITT - CRC 16 Field (16 Bits) - This field includes the 16-bit CCITT - CRC 16 calculation of the three header fields. This value is compared with the CCITT - CRC 16 code calculated at the receiver. The ISL3873B receiver will indicate a CCITT - CRC 16 error via CR24 bit 2 and will lower MD_RDY and reset the receiver to the acquisition mode if there is an error. The CRC or cyclic Redundancy Check is a CCITT CRC-16 FCS (Frame Check Sequence). It is the ones complement of the remainder generated by t…
