## **Features** - Supports All IEEE Standards IEEE 802.11ac/a/b/g/n/d/e/h/i - Operates over ISM bands (2.4GHz and 5GHz) 20MHz / 40MHz / 80MHz Bandwidth Transmission - e Backward compatible with 802.11a/b/g devices e while operating over 802.11n - Modulation - OFDM with BPSK, QPSK, 16QAM, 64QAM and 256QAM - Convolutional Coding Rate: 1/2, 2/3, 3/4, and 5/6 - Maximum Data Rates at - 72.2 Mbps Using 20MHz bandwidth WiFi Direct and support for WiFi P2P PAN network - 150 Mbps Using 40MHz bandwidth - 433.3Mbps Using 80MHz bandwidth ## **Overview** The LM808 WiFi USB Adapter uses a USB 2.0 interface in order to communicate with the host. It uses a Realtek IC that fully supports all of the 808.11 Bands, IEEE 802.11 ac Draft 2.0 and 802.11 a/b/g/n specifications, plus is backward compatible while using 802.11n standard. The LM808 Series Adapter is for users requiring a high-performance wireless client. Also supporting the WiFi Direct feature that can easily build a WiFi P2P PAN network. The LM808 supports the Orthogonal Frequency Division Multiplexing (OFDM) with one transmit and one receive path (1T1R). Features include support for both 20MHz, 40MHz and 80MHz channel bandwidth, and combined with BPSK, QPSK, 16QAM, 64QAM and 256QAM modulation of the individual subcarriers and offers a compatible coding rate of 1/2, 2/3, 3/4, and 5/6, and provides up to 433.3 Mbps over IEEE 802.11ac while using 80MHz bandwidth. **LM808** **+44(0) 207 428 2647 | sales@lm-technologies.com** Page 1 of 3 ## **LM808 WiFi 802.11ac/b/g/n Adapter** Host Controller Interface (HCI) via USB Interface Product LM808 Part No See Last Page ## |Product Name|LM808| |---|---| |Chipset|Realtek| |No. of Transmitters|1T 1R| |Standard|IEEE 802.11ac/a/b/g/n/d/e/h/i| |Data Transfer Rate|1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48, 54, 60, 90, 120, 150, 173.3, 180, 240, 270, 300, and maximum of| ||433.3Mbps| |Modulation Method|CCK, DQPSK, DBPSK, BPSK, QPSK,16QAM, 64QAM, 256QAM| |Frequency Band|2.4 GHz and 5 GHz ISM Band| |RF Output Power|17dBm – 802.11b @ 11Mbps| |(tolerance ±2dBm)|15dBm – 802.11g @ 54Mbps| ||13dBm – 802.11a @ 54Mbps| ||13dBm – 802.11n @ MCS7_HT20| ||13dBm – 802.11n @ MCS7_HT40| ||11dBm – 802.11ac @ NSS1 MCS9_BW20, BW40, BW80| ||-82dBm – 802.11b @ 11Mbps -71dBm – 802.11g@54MBps| |Receiver Sesitivity|-67dBm – 802.11n @ MCS7_BW20| ||-64dBm – 802.11n @ MCS7_BW40| ||-57dBm – 802.11ac @ NSS1_MCS9_BW20| ||-54dBm – 802.11ac @ NSS1_MCS9_BW40| ||-51dBm – 802.11ac @ NSS1_MCS9_BW80| |Operating Temperature|0° to +70° C ambient temperature 5 to 90 % (non-condensing)| |Storage Temperature|-40° to +80°C ambient temperature 5 to 95 % (non-condensing)| |Dimension|29.5mm x 15.0mm x 8.0 mm (L x W x H) USB Type A Connector + Housing| **==> picture [470 x 155] intentionally omitted <==** **----- Start of picture text -----**
