 CHAPTER 1:  INTRODUCTION  ©2005 IMobileNet, Inc.  Revision & Copyright  HSBS User Manual 516.80540.UM-Rev. D 1-Jun-07     Page 6 of 38  Product Description    The content of this manual applies to all frequency ranges of the IPSeries Base Stations, unless otherwise specified.  This manual will note key differences between frequency ranges when appropriate.   The IPSeries Base Stations are intelligent devices designed for stringent requirements of mobile data communication systems.  Intended for mounting in rack units, the base station requires very little room at tower sites and may be connected via Serial Line Internet Protocol (SLIP) or Ethernet ports. At the minimum, the unit requires a 13.8 VDC power supply, an RF Filter Antenna System, and a high-speed data connection to an Internet Protocol Network Controller (IPNC) system to operate.  The base station is typically teamed up with a Power Amplifier (PA) and third-party system components such as antennae, preamplifiers, preselectors, filters, and combiners.                 Figure 1:  Base Station External Illustration (Front View)     Product Functionality  The base station utilizes a high-performance DSP to modulate/demodulate 4 to 16-level Frequency-Shift Keying (FSK) modem for 25 and 50 kHz channel spacing, a multi-layered approach to signaling reliability, including patented multi-receiver Intelligent Diversity Reception™, dynamic scrambling, data interleaving for burst error protection, Forward Error Correction (FEC), and Viterbi soft-decision algorithms.  The IPSeries High Speed Base Station technology includes IPMobileNet’s Diversity Reception (DR) capability.  Diversity Reception reduces the number of fades and the effects of multi-path reception.  With the use of three (3) antennae, mounted as far apart as possible on the base station tower, the Diversity Reception System (DRS) minimizes the effects of fading.  One of the antennae is likely to receive a viable signal while the others may not.  DRS minimizes fading effects by comparing the signal levels from the three (3) antennae, and selecting the strongest signal.    Diversity is most effective when the vehicle using an IPSeries Mobile Radio is in motion.

 CHAPTER 4:  PRODUCT INSTALLATION  ©2005 IMobileNet, Inc.  Revision & Copyright  HSBS User Manual 516.80540.UM-Rev. D 1-Jun-07     Page 20 of 38   Typical Antenna Configuration  Base station antenna configurations may vary from site to site depending on the type of mounting structure, the presence of existing antennae, mounting structure loading limitations, etc.  The following information is provided as a guideline for a typical scenario.                         Figure 10: Typical Antenna Configuration    An optimal antenna mounting configuration is shown in the figure above.  The transmit antenna and receive antennae are located at different elevations.  This vertical separation provides the greatest degree of isolation between transmit and receive antennae.  The three (3) receive antennae are mounted at the same elevation and are oriented in a 120 degree triangular pattern.  A triangular orientation of the receive antennae provides optimal diversity performance in an omnidirectional pattern.    The greater the separation between receive antennae, the greater the diversity gain; therefore, the distance between antennae should be made as great as is practical.   In the event only two (2) receive antennae are used (i.e. a dual receiver diversity reception system), the receive antennae should be mounted in a broadside orientation with respect to the radio coverage area.      To prevent the antenna’s radiation pattern from becoming distorted, the immediate area surrounding each antenna should be kept free from conductive objects (i.e. other antennae, guy wires, or the tower structure itself).  The amount of clear area required to prevent pattern distorion is equal to the antenna’s near-field exclusion.
 CHAPTER 4:  PRODUCT INSTALLATION  ©2005 IMobileNet, Inc.  Revision & Copyright  HSBS User Manual 516.80540.UM-Rev. D 1-Jun-07     Page 21 of 38   Near-Field Exclusion Zone  The near-field exclusion zone (NFEZ) is the required distance between antennae to any other surfaces to improve transmit and receive performance.  The large radio frequency field that builts up around the antenna upon transmitting is essential for proper data transmission.  It can be severely corrupted by metal objects in the NFEZ.  As seen in the previous figure, the transmitting antenna is placed at the very top of the tower especially if the base station will be required to transmit in all directions (omni-directional).     If the transmitting antenna cannot be positioned on the top of the tower and must be placed on a tower arm, then it is important to realize that coverage will be shaded in the area behind the tower from the anetnna.  The installer must be certain that the area of desired coverage is away from the tower and not behind it.  Receiving and transmitting antennae should not be on the same plane, especially VHF and UHF systems where the frequency splits are relatiely small.  An antenna in the near-field exclusion zone that is tuned for the same frequency as the transmitting antenna will reradiate the signal and create unwanted effects on the transmittal signal.  The receivers will be inundated by high levels of radio frequency energy from the transmitting antenna.  This is why it is important to include vertical separation in the plan for the base station installation.  The isolation provided by 30 feet of vertical spearation can dramatically improve the performance of the base station.    An antenna’s NFEZ can be calculated as follows:        D = 2d2           λ     Where:   D is the distance to the anenna’s near field boundary         d is the antenna’s longest linear dimension (in the same units as D)       λ is the wavelength (in the same units as D)     Maximizing the distance between the receive antennae will provide maximum diversity gain and will minimize antenna radiation pattern distortion.

 APPENDIX A: BACKHAUL REQUIREMENTS ©2005 IMobileNet, Inc.  Revision & Copyright  HSBS User Manual 516.80540.UM-Rev. D 1-Jun-07     Page 28 of 38   Backhaul Systems  Considering the backhaul system between the base station location and the Internet Protocol Network Controller location is one of the most critical elements of data transmission.  Once data has been received at the base station, it must be relayed to the IPNC at the user's location quickly, accurately, and reliably.    Industry standard backhauls are appropriate for IPMobileNet data transmission as long as data is transmitted cleanly and dependably.  Depending upon conditions and accessibility, the preferred method of data transmission to the remote site is through a wired backhaul.   Wired Backhaul  The Ethernet backhaul is preferred as it uses a T1 (or fractional T1) line or equivalent, which handles larger volumes of digital data.  If the backhaul will be via SLIP connection, then four (4) wire DDS telephone lines capable of 56 kbps is recommended.      Do not order a 64 kbps line as it is incompatible with IPMobileNet’s equipment data transmission speed.  One disadvantage of using wired lines is that the system is under the control of an outside agency and telephone line faults or system outages impose potential loss of radio communication through the site affected.   Microwave Transmission Link  Using a microwave transmission link is another option, which is often used when wire cannot be brought into remote locations.  Data transmission is generally very reliable, but adverse conditions can degrade the quality of the data.  High winds, ice on the microwave dish, and other environmental variables can cause problems and prevent data or voice from completing transmitting.    Newest Backhaul  The 802.11 range of products for wireless data transmission.  Several models of 802.11 have been used successfully.    Be aware of the possibility of interference on the 2.4 GHz frequency range.  The 802.11 product should only be used for short hops with clear line-of-sight in an environment where minimal radio interference will exist.
 APPENDIX A: BACKHAUL REQUIREMENTS ©2005 IMobileNet, Inc.  Revision & Copyright  HSBS User Manual 516.80540.UM-Rev. D 1-Jun-07     Page 29 of 38    Serial Backhaul Capacity  The backhaul with the fastest speed that can provide clean, reliable, and dependable transmission should be considered when dealing with backhaul capacity.  IPMobileNet’s base stations operate at four (4) data transmission rates, which include the following:    115,200 bps  57,600 bps  38,400 bps  19,200 bps  The optimal goal is to select a backhaul data rate that remains ahead of the base station’s data transmittal.  For example:   BASE STATION  BACKHAUL  RESULTS 19,200 bps or  32,000 bps Anything less than 38,400 bps Backhaul does not have the opportunity to remain ahead of the base station’s transmittals if data packets are dropped or need to be rebroadcast from the IPNC to the base station. 19,200 bps or  32,000 bps  Anything higher than 38,400 bps System will be more efficient and always operate at the base station’s peak performance never waiting for data to arrive from the IPNC. 64,000 bps  57,600 bps Backhaul does not have the opportunity to remain ahead of the base station’s transmittals if data packets are dropped or need to be rebroadcast from the IPNC to the base station. 64,000 bps  128,000 bps Ideal rate and system will be more efficient requiring less time and operating at the base station’s optimal performance never waiting for data to arrive from the IPNC. 128,000 bps  256,000 bps Ideal rate and system will be more efficient requiring less time and operating at the base station’s optimal performance never waiting for data to arrive from the IPNC.   The 56 kbps DDS line is typically used to create the 57,600 bps asynchronous data line for the serial line Internet protocol (SLIP) connection between the Internet Protocol Network Controller location and the base station site.
