The duty cycle is the ratio of the maximum transmitter on time divided by the total cycle time which is composed of the maximum on time and the minimum off time. The maximum on time is dependent on the data rate. The 802.11 spec mandates what the maximum data payload for a packet may be. The data pay load along with packet addressing and other network overhead information determine the maximum size of a packet. The maximum transmitter on time is the longest time that it will take the radio to transmit the packet. In the case of Symbol’s Spectrum 24 products the 1 Mbps data rate is the slowest. For the cycle time the minimum off time consists of an acknowledgement from the receiver, the shortest carrier sense time and the shortest packet construction time. The acknowledgment and carrier sense times are driven by the 802.11 protocol while the packet construction time is driven by the processing power of the radio host. For access points , laptops, and workstations with fast processors the construction time is fairly short. While for hand held battery powered terminals with slower processors the construction time can be really significant. Directly related to the duty cycle is data throughput of a link. The lower the duty cycle the lower the data throughput. Longest On Time N = Maximum # of data bytes / packet OP = Overhead bytes/packet Ton = ((N + OP) * 8 bits/byte) / 10^6 bits/sec = 4.872 mS Maximum Duty Cycle Factor DCF = Ton / (Ton + Toff) Shortest Off Time CST = Carrier Sense Time APA = AP Ack time PCT = Packet Construction Time Toff = CST + APA + PCT Radios LA2400 CR-1 1Mbps FH LA3020 Duo 2Mbps FH LA3021 Proj C 2Mbps FH LA4111 T1 11Mbps DS LA4121 T2 11Mbps DS XX3010 FH Phone 1Mbps FH DM4026 DS Phone 11Mbps DS Duty Cycle Variables Radio N OP CST (uS) APA (uS) PCT (uS) AP Rmt AP Rmt AP Rmt AP Rmt AP Rmt LA2400 548 548 61 61 100 100 220 220 3000 10000 LA3020 548 548 61 61 100 100 220 220 2000 2000 LA3021 548 548 61 61 100 100 220 220 2280 2370 LA4111 548 548 61 61 100 100 220 220 1640 1660 LA4121 548 548 61 61 100 100 220 220 1600 1690 NP3010 N/A 32 N/A 80 N/A 100 N/A 220 N/A 7119 DP3010 N/A 32 N/A 80 N/A 100 N/A 220 N/A 7119 DM4026 N/A 32 N/A 80 N/A 100 N/A 220 N/A 7119 Duty Cycle Calculations Norm Nelson, Sr. EMC Engineer Page 2 of 2 11/22/00 Duty Cycle Factors Radio Data Rate AP Remote LA2400 1 Mbps 60% / -4.4 dB 32 % / -9.9 dB LA3020 1 Mbps 68% / -3.4 dB 68% / -3.4 dB LA3021 1 Mbps 65% / -3.7 dB 64% / -3.9 dB LA4111 1 Mbps 71.3% / -2.9 dB 71.1% / -3.0dB LA4121 1 Mbps 71.8% / -2.9 dB 70.8% / -3.0dB NP3010 1 Mbps N/A 10.75% / -19.4 dB DP3010 1 Mbps N/A 10.75% / -19.4 dB DM4026 1 Mbps N/A 10.75% / -19.4 dB Regulatory Addenum: FCC RF EXPOSURE GUIDELINES To comply with RF safety requirements use the specific belt clip.

LA-4121 Processing Gain Calculations Page 1 of 1 Processing Gain Calculation Symbol Technologies LA-4121 WLAN PC Card Norman H. Nelson, Sr. EMC Engineer May 8, 2000 Symbol calculated the processing gain from the jamming margin of the LA-4121 transceiver as specified in 15.247 (e)(2). Test Setup The purpose of the jamming test is to determine how effective the modulation, coding and decoding is at rejecting the corrupting influence of a CW jammer signal. Where as most setups us a BER to generate data and count errors because the modulator chip architecture prevents injecting data after chipping, Symbol chose to use another LA- 4121 as the transmitter and data generator. A link between the transmitter and receiver is made and path loss adjusted so that the BER is 10E-5. The path loss is then reduced by 10 dB so that the BER approaches zero. Finally a jamming signal is combined with the transmitted signal to degrade the system performance. The jamming signal amplitude is then adjusted to the point that the BER is degraded to 10E-5. The relationship between PER and BER is as follows. In order to get a good packet we need 8 x 1024 good bits. Stated mathematically. 1-PER = (1-BER) (8*24) . Or BER=1-(1- PER) (1/(8*1024)) . Jamming Margin Test Setup ATE Controller Mini Tower PC Signal Generator GPIB Power Meter GPIB GPIB GPIB Step Attn (50 dB) RS-232 RX Card Laptop (PER Receiver) TX Card Laptop (PER Generator) Fixed Attn (20 dB) RS-232 The major blocks of the jamming margin test are a transmitter, a receiver, and a jammer. The TX card formats and transmits packets of data consisting of 1024 bytes LA-4121 Processing Gain Calculations Page 2 of 2 each. The RX card then attempts to read each packet. The Signal Generator provides the jamming signal. The splitters combine the TX and jammer signals and provide a port to measure the power levels within the RF link. The PER Generator Laptop controls the transmit card and the PER receiver laptop controls the receiver. The ATE PC automates the test by controlling the two laptops, the Signal Generator, and the power meter. Software blocks The key to this test is three software programs Packet Generator (PG), Packet Counter (PC), and Jam Margin Controller (JMC). The first to work together to form the PER measurement system and the last to control the jammer, the power meter, and the other two software blocks. Packet Generator runs on the PG Laptop and controls the transmit card. A trigger on the serial port line commands the TX card to generate and transmit 1000 packets of 1024 bytes at a specified data rate. Packet Counter runs on the PER receiver laptop and queries the RX card for the number of packets it has received. A trigger on the serial port causes the Packet Counter to report the number of packets to the ATE Controller and reset the Packet Counter to zero. The Packet counter automatically detects the data rate of the incoming packet stream. The other Jamming Margin Controller (JMC) runs on the ATE PC and controls the Signal Generator, the Power Meter, and PGAC running on the Dual Slot laptop. PG commands the TX card to transmit a set of 1000 packets of 1024 bytes of data. The RX card receives the packets and PC sends the number of good packets received to the serial port. The functional purpose is the same as a BER meter. A new set is run every time a new trigger is received on the serial port from JMC. JMC controls the jammer, the power meter, and the Dual Slot program. JMC sets the frequency and level of the signal generator that acts as a jammer. JMC then sends a trigger to PG. The trigger causes PG to run another set of packets and PC reports the number of good packets back to JMC. The packet error rate is then converted to BER and JMC adjusts the Jammer level appropriately. A search algorithm is built into JMC to have the jammer converge to the right level for a 10E-5 BER. The jammer resolution is .1 dB. When the jammer level causes a BER of 10E-5, the JMC program turns off the TX card and commands the power meter to read the jammer power level. JMC then turns off the jammer, turns on the TX card, and measures its power. Then S is offset for duty cycle and J/S is calculated from the two power measurements and recorded to disk. In this way as the test progresses and the TX card warms up power fluctuations due to temperature are referenced out. The test is then repeated at the next jammer frequency. In this instance the test is conducted across the band of a single channel at 50KHz steps.
