FIELD OF INVENTION
The present invention relates to techniques for determining antenna alignment and more particularly but not exclusively, to such techniques for determining the alignment of antennas for base stations in cellular communications systems and the like such as microwave radio antenna on cell towers.
BACKGROUND OF THE INVENTION
The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.
The expansion in the fields of electronics and communication, signal processing, antenna theory and information theory have all contributed to the ubiquitous growth of wireless communication systems. However, despite the tremendous advances since the days of Marconi in each of these fields, the desire for improved wireless communication systems has not been quenched. The antenna system is one fundamental area where still there is a need for improvisation for effective transmission and signaling.
An antenna system is an electrical device which converts electric power into radio waves, and vice versa. The system is usually used with a radio transmitter or radio receiver. In transmission system, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high-frequency alternating current (AC)) to the antenna's terminal system, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception system, the antenna intercepts some of the power of an electromagnetic wave to produce a tiny voltage at its terminals that is applied to a receiver to be amplified to receive the

signals. The antenna consists of material that conducts electricity arranged in such a way that it is in tune with the frequency of a radio signal.
The wireless communications rely on telecommunication antennae to transmit information to wireless devices such as mobile telephones including cellular, PCS, GMS and the like. Today we find a variety of antennas in our device system also that enables us to provide connectivity on a wide range of technologies. In large part to mobile phones, the average user now carries one or more antennas on devices wherever they go, and cell phones can have multiple antennas, if GPS is used, for instance. In such device, the antenna system plays a crucial role in transmission of signals and can have multiple antennas system like GPS IFA Antenna, Diversity Cell Antenna, High Band Arm Antenna, Low Band Arm Antenna, Transmit/Receive Antenna (Dual Band IFA) Antenna, etc.
The telecommunications tower antennae system is generally placed at the top of the tower and at higher altitudes, such as on transmission towers and hi-rise buildings. The antennae system must be aligned with an orientation point, with azimuth (within a horizontal plane/Heading), pitch (M-Tilt) and roll in the field with a considerable degree of precision for optimum broadcast and reception quality in addition to achieving a maximum broadcast range. In order to provide the required radio signal throughout a defined area, each directional antenna in a cellular communications system is intended to face a specific direction (referred to as “azimuth”) relative to true north, to be inclined at a specific downward angle with respect to the horizontal in the plane of the azimuth (referred to as “tilt” aka “pitch”), and to be vertically aligned with respect to the horizontal (referred to as “roll” aka “skew”). Undesired changes in azimuth, tilt, and roll will detrimentally affect the coverage of a directional antenna. In general, the more accurate the installation, the better the network performance that may be achieved within the area served by the antenna.
Typically, for antenna alignment, surveyors are used to align the antenna using given coordinates and geodesic reference points, which are typically taken at

ground level. Once this information is processed, an installation expert is required to ascend the structure and gradually align the antenna using an iterative process, using the coordinates furnished by the surveyors. After this adjusting procedure is complete, the installer bolts the antenna securely to its base and moves on to the next antenna. While this procedure is relatively straightforward, it suffers from several significant disadvantages. On-site calculations require two highly trained people on the ground to gather pertinent information, which then must be processed and registered by the surveying company. This is often expensive, especially if multiple measurements are to be made. In addition, the procedure often requires hiring individuals with expertise in working at high altitudes, such as high steelworkers and wall scalers. Again, this can further increase the expense of aligning the antenna. Thus, there is a need for an improved antenna alignment system.
Also, an antenna's azimuth, tilt, and/or roll can change over time, due to the presence of high winds, corrosion, poor initial installation, vibration, earthquakes, hurricanes, tornadoes, or other factors. The service providers must conduct periodic audits of their communication antennas to ensure that each antenna has not deviated significantly from its desired azimuth, tilt, and/or roll directions. The service providers frequently hire third-party tower companies to perform audits and to make any necessary adjustments to maintain the desired alignment. Such audits, however, may be labour-intensive and dangerous, frequently requiring certified tower climbers to physically inspect each antenna, and to take appropriate measurements to determine any deviance from the desired positioning. This task can become even more time consuming if many towers are affected because of a natural calamity such as earthquake hurricane or storm, in which case, it could take between two to four months to determine which towers have been affected, as the antennas must be checked one by one.
There exist known techniques for determining whether an antenna is properly aligned or is maintaining its proper alignment. The differential GPS (Global

Positioning System) is one of the most common techniques used to measure antenna parameters. Some of these techniques make use of magnetometers, accelerometers, gyroscopes, and/or GPS (global positioning system) receivers to determine the current alignment of an antenna and/or to detect changes in antenna alignment over time.
One of the known prior art solution, for example, describes techniques that detect changes in an antenna's alignment using gyroscopes and accelerometers. The described method acknowledges the inherent weakness in using magnetometers in that they are “subject to local distortions in the earth's magnetic field” and, as a result, only claims “to detect only the relative change from an antenna's previously satisfactory orientation,” not its current alignment. In addition, the described method does not address the antenna's geolocation (i.e., latitude, longitude, and altitude).
The Antenna Interface Standards Group (AISG) released the two extension specifications Standard Nos. AISG-ES-ASD v2.1.0 and AISG-ES-GLS v2.1.0 defining the required functionality of alignment sensor devices and geographic location sensors, respectively, which requires devices to determine and report the current alignment and position of an antenna over the existing interface defined by Standard No. AISG v2.0, the teachings of all three of which are incorporated herein by reference in their entirety. By doing this, the industry has expressed a specific need for a means of continuously monitoring the current alignment and position of base station antennas that can be seamlessly integrated into the existing infrastructure. The AISG alignment extension specification allows the operators of antennas to set desired angles for things like azimuth pointing angle and mechanical tilts. It further allows the operators to set “thresholds” which will subsequently trigger alarms if the angles change from the desired angles such that the thresholds are exceeded.
It is also possible to change the “Electronic Tilt” of the antenna. In this case, the physical orientation of the housing of the antenna doesn't change, but the

effective angle of the beam can be adjusted. There are several methods for doing this including adjusting the power levels and/or phase of the signal to radiating elements internal to the antenna. This can be done using circuitry internal to the antenna which typically includes a controller. Typically, this is controlled remotely via the AISG interface. This concept is called Remote Electronic Tilt or RET.
Further, one another known prior art solution for example, describes techniques that detect changes in an antenna's alignment using gyroscopes and accelerometers and takes care of “local distortions in the earth's magnetic field” and, as a result, claims to detect not only the relative change from an antenna's previously satisfactory orientation but also its current alignment. In addition, the described method addresses the antenna's geolocation (i.e., latitude, longitude, and altitude). The described method acknowledges the inherent weakness in not using NB-IoT framework to determine and report the current alignment and position of an antenna over the existing interface and continuously monitoring the current alignment and position of base station antennas that can be seamlessly integrated into the existing infrastructure with NB-IoT framework.
Recently, 3GPP has introduced a new technology NB-IoT in release 13. The low-end data applications can be met with this technology. The NB-IoT technology has been implemented in licensed bands. The licensed bands of LTE are used for exploiting this technology. This technology makes use of a minimum system bandwidth of 180 KHz i.e. one PRB (Physical Resource Block) is allocated for this technology. The NB-IoT is a separate RAT (Radio Access Technology). The NB-IoT can be deployed in 3 modes “in-band”, “guard band” and “standalone”. In the “in-band” operation, resource blocks present within LTE carrier are used. The inner resource blocks are not used as they are allotted for synchronization of LTE signals. In “guard band” operation, resource blocks between LTE carriers that are not utilized by any operator are used. In “standalone” operation, GSM frequencies are used, or possibly unused LTE bands are used. Release 13 contains important refinements like discontinuous reception (eDRX) and power save mode. The PSM

(Power Save Mode) ensures battery longevity in release 12 and is completed by eDRX for devices that need to receive data more frequently.
The NB-IoT technology focuses on devices like meter reading of water and electricity consumption that are stationery. Some of the use cases are: facility management services, fire alarms for home and commercial properties, tracking of persons and objects. The industries where NB-IoT services can add value are: Smart city, smart home, Safety and security, agriculture, health care and Energy. Another example for IoT industry includes logistic tracking. The tracking devices on shipping containers send huge volumes of sensor data that are collected and taken for analysis to make sure that real-time tracing of shipment locations can be made possible. The output display units are used for receiving alerts and optimized with service recommendations. The NB-IoT technology support low power consumption, use of low-cost devices and provides excellent coverage.
Issues with the current approach:
In the current scenario of Antenna design system, a literature survey of various antenna alignment designs was done to understand the existence of any such antenna alignment design that meets not only the form factor but also supports existing network with NB-IoT framework. The antenna parameters are among very important data of antenna system which are frequently used in optimizing the network performance. The network operators use different methods to measure antenna parameters on time to time basis to update their database.
The current system also does not have any such system for antenna alignment tool with NB-IoT data upload/download channel that can conduct periodic audits of the antennas to ensure that each antenna has not deviated significantly from its desired azimuth, tilt, and/or roll directions and make any necessary adjustments to maintain the desired alignment.

Therefore, in the view of the limitations of the existing prior art solutions, there arises an imperative need in the art to overcome the limitations of prior existing solutions and to provide a better antenna alignment tool with NB-IoT data upload/download channel that can conduct periodic audits to ensure that each antenna has not deviated significantly from its desired azimuth, tilt, and/or roll directions and make any necessary adjustments to maintain the desired alignment.

Referring to FIG. 5, an exemplary working flow diagram [500], depicting a process of aligning at least one antenna at a cell site in accordance with exemplary embodiments of the present disclosure is shown.
The said process of aligning at least one antenna at a cell site starts at [Step 1], at [Step 1] the NB-IoT Device [102] initiates/triggers the server [106] by sending an IMEI number to fetch/collect at least one first set of data (azimuth/tilt/roll) from NB-IoT device [102], once the user press “measurement” tab. The NB-IoT device [102] thereafter configured to start a timer [504] at a coverage server [502]. The timer [504] is initiated for a time duration of 330 seconds for entire measurement process. The coverage server [502] is a platform configured to store the information of antenna physical parameters like azimuth and m-tilt of each corresponding cell site. Also, the coverage server [502] is further configured to collect each corresponding cell site antenna azimuth and m-tilt periodically via NB-IoT device [102] through cloud server in order to have always most updated information of each antenna and which for instance may be used for determining the RF coverage and capacity data.
Next at [Step 2] the process leads to starting a timer [506] at the server [106], wherein the timer [506] is started for a time period of 300 seconds.
Next at [Step 3] the process leads to instructing via the server [106], the NB-IoT device [102] to read at said at least one first set of data (azimuth/tilt/roll) from of at least one accelerometer and magnetometer. The server [106], instructs the NB-IoT device [102] to read said at least one first set of data, by sending a data collection command to said NB-IoT device [102].

Thereafter, at [step 5], NB-IoT device [102] shares the current value of (Azimuth/Tilt/Roll) to the server [106] for measurement.
Next at [Step 6], if the measurement/calculation at the server [106] is unsuccessful, and the Timer [506] has not expired, then the server [106] re-transmits the data collection command to the NB-IoT Device [102] for re-collection of said at least one first set of data again. Also, said event of unsuccessful measurement at the server [106] is based on an error analysis, which further comprises exceeding of identified errors in the said first set of data compared to a pre-defined permissible error limit.
Next at [Step 7], if the timer [504] expires and the measurement at the server [106] was not successful then an error message is sent to the NB-IoT device [102]. The NB-IoT device [102] then displays an option to “Request for Measurement” again to the user.

Thereafter, at [Step 11], the NB-IoT device [102] aligns the at least one antenna, once the antenna parameters [i.e. the corrected (current) values] received and thereafter the NB-IoT device [102] stops the process.
Also, at [Step 12], if the 330 seconds are over at the timer [504] and there is no response from the server [106] then the NB-IoT device [102] displays an error message to the user. Also, in said event, the NB-IoT device [102] displays the user the option to “Request for Measurement” again.
