Rev 30-2015 Page 7 Configuring the WTU-518: The user has to program WTU-518 parameters. In this version of document, only the GPS, WLAN and radio configuration are described. GPS configuration:  list of allowed GNSS constellations (QZSS,GALILEO,BEIDOU,GLONASS,GPS) o GPS Only is the default mode o GPS Only + SBAS o GLONASS only o GPS+GLONASS+SBAS  Navigation model o Stationary (Default mode) o Pedestrian WLAN configuration: Set WLAN Regulatory Domain: Use this menu to choose the appropriate operating frequency bands for compliance with the local regulations of the country in which the radio unit is to be used: • CE for Europe: 2400-2483.5MHz band, 5.470-5.725GHz • FCC/RSS for US/Canada: 2400-2483.5MHz band, 5.470-5.725GHz, 5.725-5.825GHz Set WLAN Access Point Scanning Channel List: Use this menu to set the channels to be scanned in order to find an Access Point. In order to avoid interference with 2.4GHz proprietary radio, prefer 5GHz channels Set WLAN SSID: Use this menu to set the network name (SSID) which the WTU-518 has to associate to. Radio configuration: The radio parameters of the WTU-518 are: Radio data rates: The following data rates are supported:  100 kbps The packet duration is up to 22ms. Moreover, the maximum radiated output power is limited to +13 dBm eirp in Europe countries, +16dBm eirp in US (FCC) and Canada (RSS)  500 kbps The packet duration is up to 8.5 ms. Moreover, the maximum radiated output power is limited to +13 dBm in Europe countries, +16dBm eirp in US (FCC) and Canada (RSS).
Rev 30-2015 Page 8 Set Radio Regulatory Domain: Use this menu to choose the appropriate maximum radiated output power for compliance with the local regulations of the country in which the radio unit is to be used: • CE for Europe: +13 dBm eirp at 100 kbps and 500 kbps • FCC/RSS for US/Canada: +16 dBm eirp at 100 kbps and 500 kbps Set Radio frequencies: Use this menu to choose one of these sets of frequencies used in the Frequency Hopping Spread Spectrum (FHSS):  2405-2469 hopset #1 : full 2.4GHz frequency band hopset #1 {2405.5;2409.5;2413.5;2417.5;2420.5;2424.5;2428.5;2432.5;2436.5;2439.5;2443.5;2447.5;2451.5;2455.5;2458.5;2462.5;2466.5 MHz } is the set of frequencies  2405-2469 hopset #2 : full 2.4GHz frequency band hopset #2 {2406.5;2410.5;2414.5;2418.5;2421.5;2425.5;2429.5;2433.5;2437.5;2440.5;2444.5;2448.5;2452.5;2456.5;2459.5;2463.5;2467.5 MHz } is the set of frequencies  2405-2469 hopset #3 : full 2.4GHz frequency band hopset #3 {2407.5;2411.5;2415.5;2419.5;2422.5;2426.5;2430.5;2434.5;2438.5;2441.5;2445.5;2449.5;2453.5;2457.5;2460.5;2464.5;2468.5 MHz } is the set of frequencies  2405-2422 hopset : narrow 2.4GHz frequency band #1 {2405.5 MHz; 2406.5 MHz;….2421.5 MHz }  2429-2446 hopset : narrow 2.4GHz frequency band #2 {2429.5 MHz; 2430.5 MHz;….2445.5 MHz }  2452-2469 hopset : narrow 2.4GHz frequency band #3 {2452.5 MHz; 2453.5 MHz;….2468.5 MHz } The hopset has to be chosen to reduce interference with other radio equipment in 2.4 GHz frequency band. For example, if a Wifi access point is configured at channel 6, the frequency band of the access point is 2426MHz-2448MHz. Thus, the 2405-2422 hopset and 2452-2469 hopset have no interference with this Wifi access point. Set Radio Security Keys : Use the Hop Sequence and the Synchro Word keys to secure the WTU-518 network. Use the Hop Sequence key to limit the interference with another Sercel network. The Hop Sequence key defines a unique frequency sequence. Two different Frequency keys define two frequency sequences, using the same set of 17 frequencies but correlation between the two different sequences is about null.
Rev 30-2015 Page 9 Use the Synchro Word key to prevent connection to another Sercel network. The radio packets transmitted with a Synchro Word key cannot be received by a Sercel network configured with another Synchro Word key. Hop Sequence key = 1 (default),…xxx For example : Hop Sequence #1 = 10 15 1 6 11 16 2 7 12 3 8 13 4 9 14 0 5; Hop Sequence #2 = 5 0 14 9 4 13 8 3 12 7 2 16 11 6 1 15 10 ; Hop Sequence #3 = 0 5 9 14 4 15 10 1 6 11 16 2 12 7 3 13 8 Hop Sequence # = … Synchro Word key = 1 (default),…xxx Description of radio protocol: The WTU-518 uses a half-duplex transmission protocol with a Frequency Hopping Spread Spectrum (FHSS) method. A mechanism of Listen Before Talk (LBT) is implemented to avoid radio collisions inside the WTU-518 network or with an external radio network. Moreover, two security keys are configured to secure the WTU-518 network. Frequency Hopping Spread Spectrum (FHSS) The FHSS operates on a set of frequencies. It will use one frequency for a fixed period of time and then switches to another channel. The next frequency will be given by a pseudo-random sequence. In order to communicate, the transmitter and the receiver have to use the same set of frequencies, the same frequency sequence defined by the Frequency key. FHSS synchronization can be based on the date delivered by the internal GPS receiver or based on the reception of packets issued from another WTU-518. f1 f2 f3 f4 f5 f6 f1 f2 f3 f4 f5 f6 f1 f2 f3 f4 f5 f6Send packet on f2 Send packet on f1 Send packet on f6 Example of FHSS based on a set of 6 frequencies Listen Before Talk (LBT) The LBT is based on a Channel Control Access mechanism: the WTU-518 measures the Received Signal Strength Indication (RSSI) before beginning packet transmission. If the RSSI is too high, the media is said “busy” and the WTU-518 postpones the transmission for a random backoff time.
Rev 30-2015 Page 10 IMPORTANT Prior to connecting any plug, make sure there is no water inside connectors. Electrostatic discharge: Use the following guidelines to provide a static-free repair station that will preclude any ESD-related damage to electronic circuits: • All spare parts (circuit boards and ESD sensitive devices) should be stored and transported in static- shielding bags. • Unless the repair station rests on a conductive floor, chairs or stools should rest on a grounded, rigid-type, static-dissipative floor mat. • Use a static-dissipative table mat. • Wear a static-control wrist strap or foot grounder. • Provide common-point grounding for all conductive items (including personnel and soldering iron tip). • To control the discharge rate and protect workers from electric shocks, both the table mat and wrist strap should be grounded through a 1-MΩ resistor. The mat should be connected to the same earth ground point as the wrist strap. • Wear static-dissipative garments.
