It is composed of two separated parts: the frame and a lid. The lid tightens to the frame trough M5 screws, hidden by two plastic clip-on design covers. A mounting kit is screwed on the back of the enclosure, allowing several mounting configurations: wall mount, pole mount and metallic strapping. The left and right sides of the enclosure integrate two waterproof screw-in vents to equalize the pressure inside and outside. This reduces condensation by allowing air to flow freely into and out of the sealed enclosure. At the same time, they provide a durable barrier to protect the internal modules from contaminants like dust, sand, water, etc … improving reliability, safety and longer product life. The bottom side of the enclosure is dedicated for the connectors: • 1 x M25 cable gland used to introduce the Ethernet cable (PoE) inside the enclosure • 3 x N-SMB adapters used as RF interfaces for the antennas: o 1 for GNSS antenna (GPS) o 1 for WAN antenna (GSM/HSDPA/LTE) o 1 for LoRa antenna. The number of LoRa antenna interfaces can be extended to 6. • 8 x M16 blind stops. They are considered as provisions for N-SMB connectors to be used for additional antennas (LoRa or WAN) or external power supply cable gland. Blind threaded standoffs are inserted in the rear side the enclosure. They are used to screw and maintain the modules inside the enclosure. The modules can be easily inserted and extracted for maintenance and upgradability purposes. The Figure 4 below shows the different components inside the enclosure.

This offers a wide range of adjustment to cover all specific countries EIRP requirements. Antenna gain has to be considered to adjust the conducted output power to not overrule the max allowed EIRP. Description Conducted output power range Ripple in the band Variation over temperature range (-20°C to +55°C) Specification 0dBm to +31dBm +/- 2dB +/- 2dB 1.6.3.8 Out of band emissions Due to the very low noise transmitter, the LoRa LOC module is able to achieve excellent out of band emissions levels in the LTE, UMTS and GSM uplink or downlink bands. The performances are summarized in the following table: Version LoRa LOC module 868 868 868 915 923 923 LTE, UMTS or GSM band E-GSM900 UL (880-915MHz) R-GSM900 UL (876-915MHz) LTE800 (832-862MHz) GSM850 DL (869-894MHz) GSM900 UL(890-915MHz) GSM900 DL(935-960MHz) Out of band emissions -85dBm/100KHz -75dBm/100KHz -80dBm/100KHz -85dBm/100KHz -85dBm/100KHz -85dBm/100KHz The performances detailed here are worst case i.e. when transmitting at maximum output power at the edge of the band. Out of band emissions in other LTE, UMTS or GSM bands are not detailed but are obviously better. The LORA-LOC module is therefore ideal in co-localization with BTS. 1.6.3.9 Sensitivity The sensitivity performance, depending on the version, at 10% PER, 20 bytes payload is the following: Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 50 / 167 Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 Wirnet iBTS Mode SF7/125KHz SF10/125KHz SF12/125KHz SF7/250KHz SF12/250KHz SF7/500KHz SF12/500KHz 868MHz -129dBm -133dBm -141dBm -126dBm -136dBm -122dBm -134dBm 915MHz -129dBm -133dBm -141dBm -126dBm -136dBm -122dBm -134dBm 923MHz -128dBm -132dBm -140dBm -125dBm -135dBm -122dBm -133dBm The sensitivity may vary over the frequency band and over temperature as follows: Description Sensitivity variation over the band Sensitivity variation over temperature range (-20°C to +60°C) Specification +/- 1dB +/- 1dB 1.6.3.10 RSSI and SNR The Wirnet iBTS is able to receive LoRa frames from -20dBm to -141dBm, depending on the LoRa BW and SF. The Wirnet iBTS provides for each received frame, the RSSI and the SNR. The RSSI is the “signal + noise” measurement of the received frame. Due to the wide spreading modulation, the LoRa receiver is able to demodulate signals below the noise floor i.e. with negative SNR. To estimate the signal strength of the received frame, both SNR and RSSI have to be considered. As a rough estimate: • If SNR >0, the signal strength = RSSI (dBm) • If SNR <0, the signal strength = RSSI+SNR (dBm) RSSI varies from -20dBm to -120dBm. -120dBm is the noise floor measured in a 200KHz BW. SNR is between 10 to 15dB for strong signals. It is close to 0dB when the signal strength approaches -120dBm. It can decrease down to -7dB or -20dB depending on the SF: Spreading Factor SF7 SF8 SF9 SF10 SF11 SF12 LoRa demodulator SNR -7.5dB -10dB -12.5dB -15dB -17.5dB -20dB The following picture is an example of LoRa receiver characterization at SF7 / 125KHz BW.

Key parameters to optimize the radio performance The installation site is very important and can determinate the coverage area of the Wirnet iBTS. Some keys points are detailed hereafter. They are general rules that must be considered in every installation. However, each individual installation is a particular case with specific constraints and sometimes with unexpected interferers. The proximity of other emitters, bad electrical installations may cause desensitization of the LoRa receiver. KERLINK recommends performing spectrum analysis to validate the choice of the installation site. This analysis can be completed with a portable spectrum analyzer for instance. The Wirnet iBTS has also the ability to perform spectrum analysis through the Web interface as detailed in §0. This analysis is however only possible once the installation is completed. 3.1 Height of the site A key factor to have an optimized Wirnet iBTS reception is the height of installation site and moreover the height of the LoRa antenna. The Wirnet iBTS gateway must be installed as high as possible to have the better reception and wider coverage area. The figure below shows the RSSI of the signal (dBm) vs. the distance to the end point (meters) vs. the height of the Wirnet iBTS (4m, 8m, 12m and 30m). Two uses cases are presented: one for a small city configuration (urban area) and one for countryside area. The propagation model used is based on Hata model. The frequency is 868MHz in this case but performance and conclusions at 915MHz would be almost identical. The RSSI is the received signal by the Wirnet iBTS. The end point EIRP is assumed to be 25mW. The height of the end point is 1m.

The propagation channel must be well defined and known to have an efficient prediction. Radio coverage simulations are recommended before the installation of the Wirnet iBTS to make sure the gateway would cover the expected area. Contact KERLINK for more information. In a first approach, the figures below show the RSSI of the signal (dBm) vs. the distance to the end point (meters) vs. the type of area (urban, suburban, countryside, desert). The height of the LoRa antenna is assumed to be 12 meters and 30 meters. The propagation model used is based on Hata model. The frequency is 868MHz in this case but performance and conclusions at 915MHz would be almost identical. The RSSI is the received signal by the Wirnet iBTS. The end point EIRP is assumed to be 25mW.

This is obviously true when there are no obstacles between the transmitter and the receiver. However, there are, most of the time, some obstacles between the transmitter and the receiver. Then, the radio waves bump into the obstacles and are reflected or diffracted with dephasing. These diffracted waves when arriving on the receiver can cause phase cancelling with the straight line signals reducing the received power (fading). The fading effect depends on the distance between the receiver and the emitter, the nature of the obstacles and the associated out of phase. Figure 55 : Fading effects due to obstacles To minimize the fading effects, obstacles in a “Fresnel ellipsoid” must be avoided. The Fresnel ellipsoid is a theoretical ellipsoid located between the transmitter and the receiver. The radius of the ellipsoid is defined as follows: Where: • • • • • 1∗ 2∗ ∗ 1 d1 = distance from Tx antenna d2 = distance from Rx antenna f = frequency c = celerity (3E8 m/s) r1 = radius at the distance d1 A global rule is that 60% of the Fresnel ellipsoid must be clear of obstacles. In case of buildings between the end point and the Wirnet iBTS, the antenna height must be adjusted to make sure the building is not close to 60% of r1.

Figure 57 : Fresnel ellipsoid and earth curvature Example: An end point is located at 3500m from the Wirnet iBTS. The Wirnet iBTS is installed on the roof of a building. The building roof is 30 meters long vs 20m large. What is the required height of the LoRa antenna for have an optimized reception? Answer: If we want to receive end points i.e. 360° area coverage, it should be better to have the antenna located in the mid of the building roof. The antenna is therefore at 15m from the edge of the roof.

However, meeting these regulations is not sufficient to insure good coexistence with BTS when sharing the same site. This is why KERLINK has reinforced these specifications to allow the coexistence. KERLINK has designed the transmitter (LoRa-LOC module) to reduce the spurious and the noise generated in the BTS RX bands below -80dBm in a 100KHz resolution bandwidth. This is then pretty much in line with BTS specifications to insure co-localization between BTS. The measurements made on the iBTS station show typical values of -85dBm/100KHz. The receiver offers also high attenuation outside the receive band. High attenuation of out of band blockers is obtained: • >105dB at +/-10MHz • >150dB in BTS downlink bands This means that the blockers levels, due to the BTS, could be up to +10dBm causing no interference with the gateway. Based on this performance, this means that about 50dB isolation is required between the Lora antenna of the Wirnet iBTS and the base station antenna to avoid desensitization of the BTS. Specifying a minimum distance between antennas may not guarantee the 50dB isolation, unless over specifying the required distance. This is mainly due to the fact that both LoRa antenna and BTS antennas are directive antennas. This means that the antenna gain is not omnidirectional in both cases. BTS antenna have about 10 to 15dB antenna maximum gain but the gain above or below the antenna is reduced by 20dB to 30dB as described below: Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 98 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 Figure 58 : Typical antenna gain pattern of a GSM BTS Mounting the LoRa antenna just above or below the 4G antenna allows then to get 20 to 30dB isolation among the 50dB required. The LoRa antenna can be an omnidirectional antenna. The worst case would be a 3dBi antenna which has the “less directive” antenna pattern. An example is presented below: Figure 59 : Typical gain of 3dBi omnidirectional antenna We can see that the gain on the top of the antenna or below the antenna is about -15dBi to 20dBi. In case of sectorial antenna, the antenna gain above or below the antenna is also significantly reduced to -10 to -15dB as shown below: Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 99 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 Figure 60 : Typical gain of a sectorial antenna Then, taking into account the performance of the antenna, we need to get about 10 to 20dB more isolation to meet the 50dB isolation between antennas. A gap of 1 meter between antennas would insure 30dB additional attenuation. Therefore, our recommendation is to have the LoRa antenna just above the BTS antenna with 1 meter gap min. Placing the LoRa antenna below the BTS antenna could be also possible. However, this is not recommended as reception could be impacted by metallic structures in the close area. 3.4.1 Wirnet iBTS 868 Co-localization is possible with the following BTS: - EGSM900, GSM1800, GSM1900 - UMTS900, UMTS1900, UMTS2100 - LTE800, LTE 900, LTE 1800, LTE 2100, LTE 2300, LTE2600 The most difficult use case is the LTE 800 band that is very close to the 868MHz band. Actually, the end of the LTE 800 band is 862MHz whereas the beginning of the 868MHz band is 863MHz. Insuring -80dBm/100KHz at 862MHz while transmitting at 863MHz or even at 868MHz is not achievable with the state of the art of SAW filters. Therefore, the Wirnet iBTS gateway embeds specific SAW filters allowing the transmitter (LoRa-LOC module) to achieve the -80dBm/100KHz spurious limit in the LTE 800 band. Co-localization is not possible with GSM850, UMTS850 and LTE850 Note: In India, co-localization with CDMA800 / LTE 850 requires usage of a specific cavity filter. See §1.7.3.1.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 4.1 How to open the enclosure Before proceeding to the insertion of the USIM card and the connection of the power supply, the enclosure has to be opened. Note: the lid of the enclosure must be kept opened during all the installation allowing setting and checking all the connections. It must be closed once the installation is completed. 4.1.1 Standard casing version The lid tightens to the frame with 4 x M5 screws, hidden by two plastic clip-on design covers. First, remove the two plastic clips. This can be done manually, without any particular tool: Plastic clip-on (x2) Figure 61: Wirnet iBTS – plastic clips on the lid The 4 x M5 screws are now accessible. Unlock the screw with a big flat-blade screw driver (65-098 5,5x100 Stanley for instance).

There are 2 door hinges that lock the cover. You just have to open one to open the cover like a door. Due to the 2 hinges, there are then two open points that are noted as "A" and “B” on the picture below: Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 103 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 Figure 63 : Open points of the compact enclosure To open the cover, you need to use a screwdriver that must be inserted in the slots A or B. The screw driver can be a small one or a bigger one. Small flat-blade screw driver: Example: 64-978 3x50 Stanley Push the screw driver into the slot A, and lift up and down, down and up, with progressive strength and going deeper. It will clip. Don't be afraid to break it, if will be opened before, if you do it step by step (progressive, to feel the point of opening). Big flat-blade screw driver: Example: 65-098 5,5x100 Stanley Push the screw driver into the slot, (it won't enter completely) and lift up in turning the screw driver into the slot (like to drive screws into the slot). Here you have to use more strength because the lever arm is smaller.

The Ethernet connection requires an Ethernet access through a dedicated RJ45 cable. Both configurations are detailed hereafter: With USIM Subscription: Without USIM Subscription: Figure 65 : Single station installation (with USIM) Figure 66 : Single station installation (No USIM) Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 106 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 4.2.2 Multi-Wirnet iBTS installation In rare use cases, multiple Wirnet iBTS gateways can be installed on one site. The recommended WAN connection is then Ethernet. An Ethernet switch is used to interface all the gateways. Note 1: the Ethernet switch is not provided by KERLINK The configuration is detailed hereafter: Figure 67 : Multi-station installation (No USIM) Note 2: this configuration is no longer detailed in the present document Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 107 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 4.3 Electric distribution to the Wirnet iBTS 4.3.1 Safety The installation must comply with EN 60728-11 (Cabled distribution systems standard Security). Earthing is a key parameter for a secure installation. Earthing of the installation is mandatory for: Indoor installation parts: mains supply, PoE injector Outdoor installation parts: tower, pole, Wirnet iBTS mounting kit, antennas. Note: none of the earthing cables required for the installation are provided by KERLINK. A second key parameter for a secure installation is the lighting protection. In its standard configuration, the Wirnet iBTS is provided with minimal internal surge protections. The Wirnet iBTS gateways are not warranted by KERLINK in case of deterioration due to lighting. Additional surge protections are recommended in harsh environments (see §4.8). A lighting rod with a down conductor to earth is strongly recommended in most of the applications to avoid direct impacts on the aerials (antennas and Wirnet iBTS). The following picture describes all the required cables connections required for the installation, including power supply cables, data cables, RF coaxial cables and earthing connections.

The mains supply must be an indoor installation composed of: • A main electrical board including: o a circuit breaker o a surge protection type 1 o a connection to “earth” • A secondary electrical board including: o a circuit breaker o a surge protection type 2 o a connection to “earth” Surge protections type 1 and 2 are required to protect the PoE injector. Note: in case surge protections type 1 and 2 are not available, specific PoE injectors for outdoor applications are required (see § 4.3.3). 4.3.3 POE supply The Wirnet iBTS gateway is supplied by a PoE injector through an Ethernet cable. The PoE injectors are detailed in §1.7.1.1 and §1.7.1.2. The recommended Ethernet cable is detailed in §1.7.5.1. It includes two RJ45 T 568A plugs on each side Note 1: The Ethernet cable is not provided with the Wirnet iBTS. Note 2: The maximum Ethernet cable length is 100m. Note 3: The PoE injectors are considered as limited power sources The installation of the PoE cable is detailed in §4.6.3. 4.3.4 Auxiliary power supply The Wirnet iBTS can be also supplied with an auxiliary DC power supply as a solar panel for instance. The input voltage range is 11 to 56VDC. A 24V DC solar system is then recommended for optimized performance. The power supply must be qualified as a limited power source. The maximum power is 30W. The nominal current for a 24V power supply is about 1.2A in the following configuration: • HSPA in a network attached mode • 4 LoRa LOC modules / all demodulators activated • 20% CPU load A two-wires cable is required to interconnect the auxiliary power supply connector.

Additional Lora modules can be added to fulfill the needs. To add a LoRa module in the Wirnet iBTS enclosure, follow the procedure below: • Insert the LoRa module into the enclosure. Place it close to the available blind threaded standoffs on the back of the enclosure. • Slide the new LoRa module on the left, close to the previous installed module: o Ensure the back panel connector is properly inserted into the previous module o Ensure the radiator of the new module get in contact with the radiator of the previous module • Screw the module on the blind threaded standoffs with the provided M4 screws • Screw the wing screws on top and on the bottom of the radiators Note: to remove a LoRa module, use the same procedure. Once the module is properly installed, then one or two N-SMB adapters are required for the antennas connections, depending on the chosen configuration. To add a N-SMB adapter, follow the procedure below: - Unscrew the M16 blind stop - Screw the N-SMB adapter on the bottom side of the enclosure - Connect the SMB-SMB coaxial cable between the N-SMB adapter and the RF1 (and RF2) port of the LoRa module Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 110 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 4.5 Mounting of the enclosure 4.5.1 General considerations The Wirnet iBTS enclosure must be mounted on any concrete pedestal, concrete wall or any non-flammable surface (UL94-V0). It must not be mounted on a flammable surface. The mounting kits delivered with the Wirnet iBTS stations allow fixing the product in different ways: - Wall mount - Pole mount by U-bolt - Pole mount by metallic strapping Two different mounting kits are available depending on the casing: - One for the Standard casing - One for the Compact casing Universal antenna brackets or specific antenna brackets are provided with the LoRa antennas. Universal antenna brackets can be directly mounted on the Compact casing mounting kit. Dome antenna brackets are provided with the LTE antennas and GNSS antennas. All these several kits are detailed in the following paragraphs. 4.5.2 Antennas mountings kits 4.5.2.1 GPS, LTE and LoRa antenna considerations The Wirnet iBTS integrates GPS, LTE and LoRa antennas. GPS and LTE antennas can be integrated inside the enclosure (compact casing) or are external to the enclosure (standard casing). The LoRa antennas are always external to the enclosure. The position of these antennas, in an open environment, is important and could determine the overall performance of the Wirnet iBTS. The GPS antenna requires an open sky view to be able to receive a maximum number of satellites. This determines the PPS clock accuracy and finally the TDOA / geolocalization accuracy. The antenna is provided with a 5m coaxial cable. Extension coaxial cables could be used to reach the optimum sky view but are not provided by KERLINK. The LTE antenna requires an open environment to optimize the link with the BTS in the area. The benefits are less multipath fading and better data throughput.

Extension coaxial cables of could be used to reach a better position but are not provided by KERLINK. However, beware of the insertion losses! The LoRa antenna requires an open environment to optimize the link with the end-points. The benefits are less multipath fading and optimized coverage area. The antenna is provided with a 1m coaxial cable. Extension coaxial cables of could be used to reach a better position but are not provided by KERLINK. However, beware of the insertion losses! 4.5.2.2 Distance between antennas 4.5.2.2.1 LoRa antenna vs. LTE antennas To avoid or minimize the intermodulation between the LoRa transmitter and the LTE transmitter, a minimum distance is required between the LoRa antenna and the LTE antenna. This minimum distance is also recommended to avoid mutual desensitization of the receivers. With the Wirnet iBTS standard casing, it is very simple to ensure the required distance between antennas because they have separated antenna brackets. With the Wirnet iBTS compact casing, the separation between antennas is more complex as the LTE antenna is internal (cannot be moved apart) and the LoRa antenna could be mounted on the universal antenna bracket tightened to the compact casing mounting kit. To optimize the colocation between the internal LTE antenna and the external LoRa antenna, a distance of 20 cm is required between both radiated parts. Therefore, when possible we strongly recommend dissociating the universal antenna bracket away from the compact enclosure support. This is the best way to guarantee the 20 cm min distance between LTE antenna and LoRa antenna. When the dissociation is not possible, the LoRa antenna must be placed on the right side of the enclosure as described on Figure 69.

There are no miracle formulas helping to determine the distance because each use case is a particular use case. However, there are some rules to be followed: • The minimum distance between antenna must be the half wave length i.e.: o 18 cm at 868MHz o 17 cm at 915MHz • To have uncorrelated antennas it is better to have a minimum distance of 13*λ/8 between antennas i.e.: o 56 cm at 868MHz o 53 cm at 915MHz • The distances can be increased to improve the performance, ideally by steps of a wavelength. The recommended distances are then: o 868MHz: 56 cm, 91 cm, 125 cm, 160 cm, etc… o 915MHz: 53 cm, 86 cm, 119 cm, 151 cm, etc… Note 1: the distance between the two universal antenna brackets installed on the compact casing mounting kit is 20cm. This meets the 18cm minimum distance for space diversity although the performance is not optimum. Note 2: the universal bracket length is about 20cm. In a 120mm pole mount configuration, the maximum distance between antennas can be the 20+20+12=52cm which is close to the optimum distance listed above.

The USIM card to be used with the Wirnet iBTS must be a 2FF format. KERLINK recommends the usage of a M2M UICC compliant with 3GPP TS 102.671. It offers then a better temperature operating range, improved data retention and increased number of UPDATE commands. Before inserting the USIM card, pay attention that the Wirnet iBTS is unpowered by checking that all LEDs of the CPU module are OFF. USIM card insertion is based on a push-push mechanism. Then, to insert a USIM card in the WAN module, follow the procedure: • Open the enclosure (see §4.1) • Insert carefully the USIM card in the WAN module respecting the USIM orientation drawn besides the connector and as shown below • Push the USIM card and released pressure until a “click” can be heard. Insert and press the USIM card here Figure 124 : USIM Card In case of replacement of the USIM card, the power supply must be firstly switched off by disconnecting Ethernet wires or disconnecting the POE injector. For few seconds, the Wirnet iBTS is still powered-on due to the internal backup battery. Wait and check the LEDs are switched off before extracting the USIM card. Simply push the USIM card to extract it from the WAN module.

In case of change of mobile operator, APN and login/password must be updated. This can be done through USB update or through the local maintenance Web interface. For more details, contact KERLINK. 4.7.2 Power ON Once the RF antenna(s) and the Ethernet cable are connected and the USIM card is inserted, the Wirnet iBTS can be powered ON. To POWER ON the Wirnet iBTS, connect the POE injector onto the 230VAC mains supply. 4.7.3 Functional check To ensure the Wirnet iBTS is started up, check the behavior of the LED indicators on the CPU module: Connector LOCAL LOCAL PoE/LAN PoE/LAN DEBUG DEBUG LED Green Orange Green Orange Green Orange Description Ethernet data activity Ethernet Link Ethernet data activity Ethernet Link Power status Software status/ activity When the Wirnet iBTS is powered ON then, all the LED are switched ON during seven seconds. Then the DEBUG green LED must be ON to indicate the power supplies are OK. The DEBUG orange LED is blinking very fast during two seconds at the end of the boot. Once the boot is completed and the Wirnet iBTS is in nominal configuration, then the DEBUG orange LED is blinking every 5 seconds. Then, to check and analyze the status of the Wirnet iBTS, a standard laptop can be connected to the LOCAL RJ45 connector of the CPU module or the LOCAL RJ45 connector of the PoE injector. Once connected, run the maintenance Web interface as explained in chapter 5.3.4. 4.7.4 Configuration A local maintenance Web interface is available to perform the specific configuration (IP address…).

In harsh environment, additional protections may be used to improve lightning immunity. The Wirnet iBTS gateways are not warranted by KERLINK in case of deterioration due to lighting. KERLINK recommends adding surge protections, especially in high keraunic levels areas and on high points. The lighting surge protection must be completed on three interfaces to be efficient: - Mains supply - Ethernet (PoE) cable - RF coaxial cable (antenna interfaces) Another key parameter for an efficient lighting surge protection is “earthing”. The earthing connection insures that the lighting surge is driven to the ground properly. Earthing of the installation is mandatory for: - indoor installation (mains supply, PoE injector) - outdoor installation (tower, pole, …) The following figure describes the lighting protections that are required in a high keraunic area configuration: Figure 125 : Installation with recommended lighting protections Classification Internal Use Confidential Strict confidential This document is the strict property of Kerlink and shall not be either copied nor sent without express written authorization of Kerlink Kerlink m2m technologies reserved rights Kerlink – 1 rue Jacqueline Auriol – 35235 THORIGNÉ-FOUILLARD Page 152 / 167 Wirnet iBTS Document title : Installation and Maintenance Manual Version : 0.6 Author : MGI Date : 16/08/31 The installation is composed of two separated areas: indoor installation and outdoor installation. The indoor installation is composed of: • A main electrical board including: o a circuit breaker o a surge protection type 1 o a connection to “earth” • A secondary electrical board including: o a circuit breaker o a surge protection type 2 o a connection to “earth” • The PoE injector (see §1.7.1.1 and §1.7.1.2) • An Ethernet surge protection, connected to “earth” (see §1.7.6.2) The outdoor installation is composed of: • A tower, mast or pole that must be connected to “earth”. • The Wirnet iBTS and its mounting kit. The mounting kit must be connected to earth. • The antennas (LoRa, LTE, GNSS) with their RF coaxial surge protections (see §1.7.6.1) connected to “earth”. A lighting rod with a down conductor to earth is strongly recommended for this kind of applications. The lighting rod avoids direct impacts on the aerials (antennas and Wirnet iBTS). Note 1: the PoE injector must be connected to the mains supply through a main electrical board with surge protections type 1 and a secondary electrical board with surge protections type 2. If the electrical installation does not meet those requirements, use an alternate PoE injector featuring better surge protection. Contact KERLINK for more information. Note 2: the PoE injector is intended for indoor applications only. Note 3: the Ethernet surge protection is intended for indoor applications only. In some use cases the electrical installation does not have the required surge protections type 1 and type 2. Also, the PoE injector and Ethernet surge protection could not be installed indoor. Therefore, an alternate PoE injector and an Ethernet surge protection dedicated to outdoor applications are required. These are detailed in §1.7.1.3, § 1.7.1.4 and §1.7.6.3. In this use case, the installation is still composed of two separated areas: indoor installation and outdoor installation.
