Authorisation This document has been seen and accepted by: Name Designation N Bailey IARC Corporate Manager Development Technology P Groenewald IARC Control Technologies Manager Z Gydien IARC Telecomms Discipline Specialist This document shall apply throughout Eskom Holdings Limited, its divisions, subsidiaries and entities wherein Eskom has a controlling interest. Introduction Eskom relies extensively on GSM/GPRS modems at installations for applications such as Metering and Telecontrol to remotely retrieve data or to control the electrical network. If these installations are done without proper telecommunications design and application, it will result in some of these systems operating at a less than optimal level of communications. The following problems have been reported and observed on audits: 1. Supplied whip antenna has as omni-directional radiation pattern where often a directional antenna is preferred. 2. The coaxial cable of the supplied whip antennas have a high attenuation and have poor propagation and interference properties. 3. Mounting of whip antenna on top of the panel and routing the coax through the doorway results in the coax becoming pinched and damaged by the door. 4. The mounting of whip antennas on top of equipment panels inside substations resulting in RF radiation (EMI) which may result in maloperation. 5. Multiple whip antennas are placed on top of a cabinet to cater for large number of meters. 6. Antennas left inside meter enclosures which results in poor comms when the door is closed. 7. Whip antennas mounted horizontally on the side of a panel when the signal is vertically polarized resulting in poor signal propagation. 8. Whip antennas are not suited for outdoor use. 9. Installations carried out without knowing the actual radio signal strength between the cellular base station and the Eskom site, resulting in some installations having a poor comms performance. This cell modem communication design guideline will provide procedures and practical steps needed to ensure correct installation standards and practice to be adhered to for the installation of antennas for the cellular modems.
3 Page: 3 of 25 Keywords Cellular, GPRS, Modem, Metering, Telecontrol, antenna, design 1 Scope This document is a design guide to assist the Project Engineer and the Field Technician in specifying the correct antenna arrangement and installation practice for modems connected to the cellular networks at various Eskom and Customer installations. The guideline includes modems used for Metering and Telecontrol. But can also be used in other cases where a cellular modem is used for GSM/GPRS communications. This includes antennas internal to the building as well as external antennas where the need arises due to either poor signal strength at the pole or substation or due to restrictions on the permissible radiated RF within the building. This document excludes the specification for procurement or installation of the cellular modem itself. 2 Normative references Parties using this document shall apply the most recent edition of the documents listed below: NRS 043:1997 First Edition: CODE OF PRACTICE FOR THE JOINT USE OF STRUCTURES FOR POWER AND TELECOMMUNICATION LINES. Technical Bulletin DT 018/97 Rev.2: Auto-Recloser Earthing. TECHNICAL BULLETIN: 06 TB 036: Restricted use of Cellphones in substations DISREAAH3 Rev.0: Working clearances at MV structures with pole-mounted auxiliary equipment 3 Definitions and abbreviations 3.1 Definitions Cell modem : A modem that interfaces over the air to the GSM cellular network Base Station: GSM cellular radio on a high site. db: A logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power) relative to a specified or implied reference level.

4 Page: 4 of 25 GPS: Global Positioning System GSM: Global System for Mobile communications HV: High Voltage RSSI: Received Signal Strength Indication 4 Design Process The design of cell modem communication links shall follow the following process: a) Obtain the co-ordinates for the site. b) Calculate the theoretical signal strength. c) Measure the signal strength on site if the theoretical signal strength indicates marginal signal strength. d) Determine the type of installation (i.e. indoor vs outdoor etc.) based on site requirements. e) Choose between installing a whip antenna, outdoor antenna or a high gain antenna f) Determine equipment arrangement. g) Draw up scope of work. h) Determine bill of materials. In addition to the above steps also refer to the flowchart in Annex A. 4.1 Determining the Strength of the Received Signal Theoretical Model i) Submit the site name and co-ordinates to the cell phone network provider. j) Request the following information from the cell phone network provider: A calculated received signal strength level from their nearest base station. The base station name. Direction to their base station from your position. Frequency band of their base station (900MHz and/or 1800MHz) On Site Signal Strength Test Measurement The following equipment required to carry out the measurement tests: a) A cell modem
5 Page: 5 of 25 b) PC loaded with the relevant cell modem software for measuring signal strength. c) Whip antenna and coax supplied with the cell modem. d) A GSM Yagi antenna, of known gain, mounted on a 3m portable pole. e) 5m Coaxial cable flylead with a known attenuation at 900MHz. Connect the cell modem to the PC and run the cell modem software. Connect the supplied whip antenna and coax to the cell modem and mount the antenna on top of the equipment panel. Measure the received signal strength using the software. The received signal level should be 10dB above the sensitivity of the cell modem receiver (in most cases this will mean a level greater than -92dBm) to allow for a suitable fade margin. A signal better than 92dBm (see Table 1), therefore, represents a good signal. Table 1: Modem signal level vs dbm RSSI < >20 dbm < > -73 If the signal strength is less than the desired signal strength then take the measurement using the high gain antenna and separate coaxial flylead outside the building in approximately the same place as the intended antenna mounting. Using the high gain antenna fitted to a pole, point the antenna in the direction of the cellular base station. Use the information supplied by the cellular network provider. Measure the received signal from the base station. (Check the name of the base station to make sure that you are measuring the correct signal) Pan the antenna to obtain the best possible result. The actual signal strength of the final installation shall be calculated from the measured signal as follows: Final signal at modem = (Measured test result) + (test coax loss) (installed coax attenuation) (panel flylead coax attenuation). (Assuming the same antenna as the test antenna is to be used, otherwise subtract the test antenna gain and add the installed antenna gain). See Annex B for typical coax attenuation losses and Annex D for typical calculations. The final signal at the modem shall be equal to or better than -92dBm. 4.2 Installation Design Antenna Considerations The whip antenna that is supplied with the cell modem is only designed to be used indoors, as it is not robust, and is prone to rust and theft. It should therefore not be considered for an outdoor installation. Refer to Annex B for more information. An indoor whip antenna may not be used where its use is prohibited (i.e. TB 036 prohibits cell phone use under certain conditions in all substations). A cellular modem is to be treated in the same way as a cell phone. The whip antenna produces a RF propagation of higher gain than a handheld cell phone. If the received signal strength at the modem using an approved low gain antenna is not adequate (i.e. > - 92dBm) then a high gain outdoor antenna should be considered on a separate elevated pole. Under no circumstances should a high-gain antenna be used indoors. The outdoor antenna should be installed so that it does not point into or across HV yards/steel structures, or along the length of a line. Minimum antenna spacing of 0.5m applies where the metering antenna shares the same pole as the antenna used for telecontrol communications. Earthing standards are to be adhered to.
6 Page: 6 of 25 Refer to Annex B for more information about the different types of antennas available and suitable for cell modem installations. Wherever possible, it is recommended that only one antenna is used for multiple meters. By using the RS485 data interface a single GSM/GPRS modem can be connected to multiple meters using the same data interface Co-axial Cable Considerations The coaxial cable supplied with the cell modem is usually RG174, which is an inexpensive and high-loss cable. It should only be used in installations where the supplied whip antenna is used. In all other installations, the use a coaxial cable with the lowest possible loss as is practical is recommended. Refer to Annex D for information on different types of suitable coaxial cables. Coaxial cable runs should be as short as possible and attempt should be made to limit the coaxial cable attenuation to <2dB. See Annex B for coaxial cable attenuation details. For an external installation at a building, an earth kit on the coaxial cable must be used. Use only approved easy to fit high spec coaxial connectors so that the maximum total connector loss in the installation is lower than 0.5dB. All fly leads and connectors must be made up by a company or resources with the necessary skills to do so. 4.3 Installation Guidelines Note: The minimum bending radius of the coaxial cable is 100mm. Care must be exercised not to damage the coaxial cable when doing the installation. Care must also be taken not to damage the Telecontrol coaxial cable Possible Scenarios a) Indoor installation where the signal strength is good and the use of cell phones (indoor antennas) is not prohibited. b) Indoor installation where the signal strength is poor but can be brought up to an acceptable level using a high gain antenna. c) Indoor installation where the RF signal strength is good but cell phones (indoor antennas) are prohibited. d) Outdoor installations where the RF signal strength is good. e) Outdoor installations where the RF signal strength is poor but can be brought up to an acceptable level using a high gain antenna Installation at a Building Indoor Antenna (Scenario (a) only) a) Mount the antenna on the top of the equipment panel b) Feed the coax to the cell modem through a 20mm hole in the panel.
7 Page: 7 of 25 c) Ensure that the coaxial cable is protected either by a compression gland or suitable protective material that lines the hole. d) The coaxial run must not be strapped to or run alongside power carrying cables or the earth bar Outdoor Antenna (Scenarios (b) or (c)) Refer to Figures 1, 2 and 3. a) Fit the wall mount bracket to the wall of the building. Use a suitably sized bracket to cater for the overhang of the roof. b) Fit the aluminium pole to the wall mount bracket c) Mount the antenna on the aluminium pole. The direction that the antenna must face is specified in the substation design schedule. d) Run the insulated earth conductor from the pole down to station earth. e) Secure the earth conductor to the pole as per Figure 3. f) Strap the coaxial clamps to the pole spaced at 1m intervals. Ensure that they are aligned vertically. g) Fit the coaxial cable connector to the antenna end of the coaxial cable. h) Run the coaxial cable from the antenna to the top of the equipment panel via the coaxial cable entry and able tray. i) Note: a rubber boot must be fitted to the coaxial cable before it is pushed through the cable entry to the building. j) Secure the coaxial cable onto the coaxial clamps. k) Fit the earth kit onto the coaxial cable just above the bend where the cable turns off the pole. l) All external earth clamps, earth crimps, earth kit and coaxial connectors must have 3 layers of rubber tape applied to ensure adequate waterproofing. m) Fit the coaxial cable connector to the end of the coaxial cable at the equipment panel. n) Fit the pre-made fly lead onto the equipment panel (a 20mm hole is required for the N-type female bulkhead through connector) and route the fly lead to the modem. (See note above for the running of this coaxial cable within the cabinet) o) Seal the coaxial cable entry into the building using the rubber boot and rubber tape. Note: If ½ copper corrugated High Flex or Heliax coaxial cable is used then a special tool for each of the cables is required to prepare the coaxial cable for the Quickfit connector. The tool can be obtained from the supplier of the connectors.

9 Page: 9 of Outdoor Installations Figure 3: Earthing of the Antenna Mounting Pole It is recommended that a robust antenna which is not prone to rust, theft or vandalism is used for outdoors installations Installation for a Site with a Good Signal (Scenario d) The ESKANT antenna (Annex B) is recommended where the received signal strength is good. The ESKANT antenna can be mounted on the on the side of the panel where provision has been made for this in the way of a pre-manufactured cut-out. By mounting the ESKANT on the side of the panel the coaxial cable will remain inside the meter panel and will not be exposed to the external elements.
10 Page: 10 of 25 Figure 4a: Concept Diagram Using ESKANT Antenna. The DOORSTOP antenna has the same RF signal gain properties as the ESKANT. It is recommended to use the DOORSTOP antenna at an installation with a wood pole and where no provision has been made to mount an ESKANT on the side of the panel or where extra height is required to clear near-side obstructions such as a building. The DOORSTOP antenna can be secured to a wood pole using screws and must face in the direction of the Cellular base station. The DOORSTOP antenna must be supplied with an N-type male connector and connected through a bulkhead connector onto an internal fly-lead.
11 Page: 11 of 25 Figure 4b: Concept Diagram Using DOORSTOP Antenna.
12 Page: 12 of Installation for a Site with a Poor Signal (Scenario e) Where the received signal strength is poor, or marginal, and the calculations show that the modem will work with a high gain antenna, then a high gain Yagi antenna is recommended. (Annex B). The antenna must be mounted as high up on the pole as safety requirements permit using a specific antenna mounting bracket. Care must be taken to adhere to the installation guide in order not to compromise the earthing of the installation. Figure 5: Concept Diagram Using High Gain Antenna on Pole.
13 Page: 13 of 25 Installation practice: a) Fit the pre-made fly lead onto the equipment panel (a 20mm hole is required for the N-type bulkhead panel mount through connector) and route the fly lead to the modem. (See note above for the running of this coaxial cable within the cabinet) b) Fit the antenna mounting bracket to the pole on the side that faces the cellular base station. The direction to the base station is specified in the design schedule. c) Mount the antenna onto the mounting bracket. d) Fix the coax clamps to the pole spaced at 1m intervals. Ensure that they are aligned vertically. e) If a bare earth is used on the pole then ensure that the earthing is not compromised by using a steel strap around the pole. f) The preferred solution is to then fix the coax clamps to the pole with coach screws or UV resistant PVC straps. g) Fit the coaxial cable connector to the antenna end of the coaxial cable. (Not required if a predetermined length of coaxial cable with fitted connectors is supplied.) h) Run the coaxial cable from the antenna to the top of the meter panel. i) Secure the coaxial cable onto the coax clamps. j) At the panel fit the male coaxial cable connector to the coaxial cable. k) Connect the coaxial cable to the panel mount connector. l) All external coaxial connectors must have 3 layers of rubber tape applied to ensure adequate waterproofing.
14 Page: 14 of Safety Considerations Figure 6: Antenna Mounting on a Pole The following minimum clearance distances in accordance with NRS 043:1997 First Edition are to be maintained at all times and are applicable to all components of the antenna installation i.e. antenna, mounting bracket, co-axial cable etc.: a) 2m to any bare MV conductors and 0.9m to any insulated MV conductor. b) 0.5m to the bottom of either the Auto Recloser and/or Auxiliary Transformer. Work done at both ground level and elevated levels on Eskom apparatus must be done in accordance with Eskom s ORHVS regulations, technical report DISREAAH3 Rev.0, and the relevant safety practices.

Very high loss. Not recommended. Can be supplied with ESKANT antenna but not preferred. Keep as short as possible. Supplied with ESKANT & DOORSTOP antennas. Flexible. Good screening. Preferred for coax tails inside panel Flexible, low cost. Preferred for installation on wood poles. Alternative to LMR400. Costs more. Can take high quality connectors. Preferred in marginal signal areas. Can only use N-type connector. Preferred for installations in a building where longer coax runs to an external pole or mast are required. Can only use N-type connector. Maximum length is a recommendation only to limit attenuation to approximately 1dB for the coax run. Every attempt must be made to limit coaxial cable losses and it is recommended not to exceed 2dB coaxial cable attenuation for the entire installation. For distances greater than 15m use the ½ Heliax up to a recommended maximum length of 30m. Coaxial cable clamps to fit specified coaxial cable. Use 30mm PVC conduit where the coax run is inside the cable trench. Use PVC cable trunking for runs up the wall. Overhead racking or cable tray is the preferred way to run the coaxial cable from the panel to the outer wall. Cable entry into the building: 50mm diameter PVC pipe protruding 50mm on the outer side of the wall. Coaxial Connectors: Coaxial cable connector types must be chosen to match the connector fitted to the modem, antenna or bulkhead (panel mount) connector. Connectors typically fitted to modem: FME - Female (left) and Male (right) SMA - Male (left) and Female (right).
19 Page: 19 of 25 Connectors used inside the panel or indoors may be made off using a crimp connection. All connectors used outdoors must be a compression type connector or a crimp connection with a high quality sealing sleeve which is guaranteed to prevent the ingress of moisture. Use weatherproof tape on all outdoor connectors. For RG-58, LMR-195 or LMR-400 coaxial cable it is recommended to order the correct lengths with the relevant connectors already fitted. For ½ High Flex and ½ Heliax a quickfit N-type connector can be fitted on site. Note a special stripping tool will be required to carry out the work. A suitable N-type to TNC adaptor may be required at the antenna end for some makes of Yagi. Pre-made fly lead inside meter panel: Use LMR-195 coaxial cable fitted with the correct connector to match the modem and external coax connectors. Use an FME or SMA connector on the modem side and a N-type female panel mount connector (keep as short as possible). Mounting brackets for Yagi antennas on the side of a building: Use a pre-made rugged mounting bracket as offered by antenna suppliers. Mounting poles: 5m Aluminium pole 50mm diameter 5mm wall thickness Mounting brackets for Yagi antenna mounting on wood poles: Have a suitable bracket made up according the suggested design in Annex E. Earth kits: Supplier to provide suitable earth kit for ½ HF or Heliax coaxial cable. Use 25mm 2 insulated green and yellow wire for connections to earth.
20 Page: 20 of 25 Annex C - Technical Data of a Typical Cell Modem Most cell modems use the Wavecom transceiver module. Transmitter RF output power: 2W Receiver Sensitivity: 102dBm External connections vary between the products of the different manufacturers. Data: RS232-9 pin or 25 pin D-type connector. RF Connector: Could be any of the following:- FME male, FME female or SMA female. Most manufacturers are standardising on the SMA connector. Power Supply: External AC adaptor or 220/110V AC internal PSU. (Some modems can be ordered with a 12V DC supply)
21 Page: 21 of 25 Annex D - Signal Strength Calculations The following calculations and examples help determine what the final received signal strength will be at an installation, based on the test measurements. Final signal at Modem = Measured test result + test coax loss final coax attenuation final panel flylead attenuation. (Assuming the same antenna as the test antenna is to be used, otherwise subtract the test antenna gain and add the installed antenna gain) Calculated coax attenuation = Loss from Table 2 / (100 x length of coax to be used). Coax Type RG174 RG-58 LMR- 195 LMR- 400 ½ HF ½ Heliax Frequency(MHz) Note: The above coax types are for information only. Refer to Annex B for the recommended list of equipment. Connector loss is deemed negligible. Table 2: Coaxial cable loss (db/100m) Example: Test coax attenuation (i.e. 5m LMR195) = 32.5/100 x 5 =1.625dB loss Coax to be installed (i.e. 20 meters ½ HF) /100 x 20 = 2.24dB loss 2 metre Panel flylead (LMR195) = 32.5/100 x 2 = 0.65dB loss Assuming a RSSI test result of 16 on the PC which then equals a received signal strength = 81dBm. Signal at the modem = = dBm (Which is approx. 10 db better than 92 and therefore more than acceptable)
