     BACKGROUND 
     Operators deploy the 5G New Radio (NR) networks and 5G devices at various sites worldwide. During the post-construction of the cell site, the general contractor, or others including the field operator, installer, vendor, etc. have to test the newly constructed 5G cell site installations in the field to ensure proper functionality of the cell site radio operations. 
     Prior to the actual commissioning of the cell site, a set of validation tests can be used to validate transmits in the cell sector covered by 5G cell sites in advance of the actual commissioning of the 5G cell site to forecast or to prevent any obstacles that may occur in advance of the actual commissioning of the 5G cell site. This can give the general contractor added assurances about the expected reliability to put into operation a particular 5G cell site. 
     It is desirable to provide a post-construction validation software tool operable at a cell site to perform a set of validations and tests of radio operations associated with a post constructed 5G cell site at about the time of the post-construction for use by the general contractor and others to generate data and assess in advance the reliability of the constructed 5G cell site and to ensure appropriate standards and operability are or will be met. 
     Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description and the appended claims, taken in conjunction with the accompanying drawings and the foregoing technical field and background.

     This summary is provided to introduce a selection of concepts in a simplified form that is further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. 
     DETAILED DESCRIPTION 
     The following detailed description is intended to provide several examples that will illustrate the broader concepts that are set forth herein, but it is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description. 
     Wireless mobile communication technology uses various standards and protocols to transmit data between a base transceiver station (BTS) and a wireless mobile device. The deployment of many small cells presents a need to validate radio operations at the post construction of the cell site to forecast obstacles and ensure reliability by the general contractor prior to commissioning the cell site. 
     In 3GPP radio access networks (RANs) in LTE systems, the BTS can be a combination of evolved Node Bs (also commonly denoted as enhanced Node Bs, eNodeBs, or eNBs) and Radio Network Controllers (RNCs) in a Universal Terrestrial Radio Access Network (UTRAN), which communicates with the wireless mobile device, known as user equipment (UE). A downlink (DL) transmission can be a communication from the BTS (or eNodeB) to the wireless mobile device (or UE), and an uplink (UL) transmission can be a communication from the wireless mobile device to the BTS. 
       FIG. 1  is an exemplary embodiment of a post construction site validation test software tool in a wireless data networking environment in accordance with an embodiment.  FIG. 1 . includes a handheld mobile device  10  that listens for specific PCIs in downlink transmits. The handheld mobile device  10  is configured with a built-in GPS service to generate geographical data for a software application  15  (hosted in part or in communication with the handheld mobile device  10 ) to receive the geographical data to correlate which cell site a handheld mobile device  15  is located, and what is the direction and azimuth angles are pointing of the transmits in each cell sector. The software application (or testing software)  15  directs the user to the optimal locations with the handheld mobile device  10  to take downlink measurements by executions of algorithms of the software application  15 . The handheld mobile device  10  links and communicates data generated by the software application  15  to other testing software  75  hosted by a laptop device  70  via a router  60  at a site cabinet  65 . The handheld mobile device  10  links back to the laptop device  70  at the end of the test to report downlink data. 
     The laptop  70  with the testing software  75  can be any computing device or other data processing apparatus or system usable by users to access the router  60 . For example, any of a desktop computer, a work station, a laptop computer, a tablet computer, a handheld computing device, a mobile cellular phone (for example, a “smartphone”), or any other Wi-Fi-enabled device, wireless access protocol (WAP)-enabled device, or other computing device capable of interfacing directly or indirectly to the Internet or other network to the router  60 . The “laptop”  70  is “computing device” that typically executes an HTTP client, for example, a web browsing (or simply “browsing”) program, such as a web browser based on the WebKit platform, Microsoft&#39;s Internet Explorer browser, Netscape&#39;s Navigator browser, Opera&#39;s browser, Mozilla&#39;s Firefox browser, or a WAP-enabled browser in the case of a cellular phone, PDA or other wireless device, or the like, allowing a user to access, process and view information, pages and applications available to over a network. 
     In various exemplary embodiments, the data that is downlink can be formatted in a file or sent in packet and can include date and time data when the test is performed and the name of a certain site with site identification information such as a site ID. The location information can be detected in the test and is based on geographical location, GPS coordinates of each sector test, results of test data including PCIs received and associated RSRP, RSRQ signal quality measurements. 
     The laptop device  70  is connected to a specific port on router  60 . The testing software  75  is configured to scan the router ports of the router  60  to automatically discover a radio  40  connected to a router port or a set of radio devices connected to multiple router ports. The testing software  75  configures the radio  40 , which is discovered for a test. The testing software  75  measures eCPRI light levels of the radio  40 , places the radio  40  into a transmit mode to generate a specific PCIs per radio per sector ( 20 ,  30 ,  50 ), executes a series of query operations to the radio to generate Voltage Standing Wave Ratio (VSWR) values of mismatch amounts between an antenna Remote Electrical Tilt (RET) connection (i.e., the feed line) to each radio. The testing software  75  drives the RET in a full range and reset the RET back to zero when the test is completed. The testing software  75  collects and records the radio  40  signal to noise (SN) values, validates MAC addresses, Received Signal Strength Indication (RSSI) values, RET S/Ns values associated with each radio  40 , and any alarms present. When executed, the laptop device  70  pairs up with the testing software  75  and the Handheld Mobile Device  10  in part to retrieve downlink transmit data and provide pass and fail validation results. The validation results are reported to the specific server over the network. 
       FIG. 2  is an exemplary flowchart of a set of radio operation tests by the testing software to validate the radio&#39;s operations at the cell at a post-construction stage in accordance with an embodiment. In  FIG. 2 , at step  205 , the testing software validates whether a newly installed gNB has been coupled or plumbed as required with the appropriate connections by a general contractor, builder, assembler, etc. before any of the project personnel have departed from the cell site and completed this installation work. At step  210 , the plumbing can include installing the fiber, RF, RET, and other connections to put in service or turn on the cell site. The plumbing also includes actions while radios are active with collecting VSWR and RSSI data. The plumbing is prior to the cell site&#39;s commissioning and is a checking or testing whether the cell site is suitable to be commissioned. At step  215 , various points are tested by configured tests of the testing software. For example, at step  220 , the testing software validates a radio power up or turn on the operation. It is tested without alarms so as not to damage any required handling and installation operations. At step  225 , the radios are placed in a minimal RF transmit mode on specified frequencies to check VSWR values. This testing validates at step  230 , that RF connects are joined or landed on correct ports to a right antenna (i.e., no mismatch of low band/high band connections has incurred). At step  235 , the validated radio detects antenna RET and can motion e-tilt actions through normal, or convention desired ranges. At step  240 , collecting and validating of RET S/Ns is performed. At step  245 , assign radios are fixed PCIs per band per sector (will use small range of PCIs set aside to avoid operational issues). 
     At step  250 , an app configured on user equipment (UE) is enabled to receive PCIs and geo location data to validate sector matches. This validation action requires all or nearly all available radios transmitting at the same or similar time. The UE can also implement the testing software to compare the best RSRP/RSRQ per PCI that is received and relates to an expected geo-location/sector to validate fiber and RF plumbing (no swapped sectors). 
     At step  260 , the testing software reports fiber light levels on both ends (ground hardware &amp; radios) to ensure the fiber is clean and the end to end loss is minimal. At step  265 , the testing software compares data from ground hardware and UE to determine “pass” or “fail” results and generate a “pass” or “fail” report of errors or validations automatically to the server. In an exemplary embodiment, the “fail” report may include sufficient details of the identified errors to enable a user to identify the cause and troubleshoot with a set of appropriate responsive hardware or software changes or corrections to address the errors. Subsequently, after making all the corrections and changes, the system can be retested to confirm that the reported errors have been overcome and no longer triggered. 
     In an exemplary embodiment, the “pass” report may include a series of tests and test log data associated with a set of metrics. The tested metrics can include the following: RU S/N and MAC addresses for each radio in each sector and the associated antenna RET S/N data (this is feedback to the NX1 and the EMS). 
     The mid-haul data is not required to validate the site as the UE is configured in a passive mode when measuring PCI and GPS location. For the UE to execute the testing software at the cell site, the testing software requires the cell site RFDS/CIQ information to calculate by a various algorithm implemented by the testing software, a set of sector patterns in relation to antenna locations of the cell site to qualify for a “pass” or “fail” report for various metrics associated with the sector patterns. 
     At step  270 , the testing software is configured to be carried out by multiple types of different ground units associated with cell sites (CSR, DU, VEP, or external laptops) and UE rendering an app. The data gathered from the ground units are necessitated to be synced to a UE app (via Bluetooth or Wi-Fi connections) for collection for the radio alarm, VSWR, RET, and fiber light level data. 
     At step  275 , an alternate embodiment is configured to enable an LTE terminal plugged into a cabinet router for a push test remotely actuated (and also automatic). In this case, the UE must operate with an app and be configured to sync to generate a pass and a fail report based on a validity test. 
     At step  280 , in another exemplary embodiment, the UE is configured with an active account to report the test results. 
       FIG. 3  illustrates the various components for a cell site configuration in accordance with an exemplary embodiment. The cell site configuration includes a 5G or other data networks  100  that includes multiple cells  121 ,  122 ,  123  that provide access to a network  105  for any number of UE devices  110 . Although  FIG. 3  shows only one user equipment (UE) device  110  for simplicity. In practice, the concepts described herein may be scaled to support environments  100  that include any number of devices  110  and/or cells  121 - 123 , as well as any sort of network architecture for assigning bandwidth to different slices and performing other tasks, as desired. 
     In the example of  FIG. 3 , a mobile telephone or other user equipment (UE) device  310  suitably attempts to connect to network  305  via an appropriate access cell  321 ,  322 ,  323 . In the illustrated example, each cell  321  includes the components for transmission of a base station controller  331 , a base station transceiver  338 , a node  340 , an RF Radio  335 , a Radio Network controller  342 ; the linking components of the antenna interface  332  and the antenna  333 ; and the power components of the commercial power interface  350 , the backup power supply  352  of a battery circuitry  354  and UPS or batteries  356 . 
     The commercial power interface  350  may receive power AC power from a public utility or other sources. The antenna  333  and antenna interface  332  control the signal to the UEs  310 . The radio network controller  342  can control the RF transmit output via the RF radio  335  to conserve power usage to reduce the power draw on the USP  356 . By reducing the communication bit rate, the RF power can be reduced in decibels (“dB”). Additionally, step reductions can be implemented. The battery circuit  354  can be configured as a rectifier type switch that can switch the output power from the UPS  356  at multiple levels. The Base Station controller  338  can include power control features to control the power drawn by the base station  338 . Additionally, the base station controller  338  can communicate wirelessly with a power management system  370  that can confirm the power outage or interrupt on the front end to change the power input power levels of multiple small cells  321 ,  322 , and  323 , and a number of UEs  310  connected to the Node  340  and resources in a slice of a node (gNB). 
     For example, the radio network controller  331  can implement logic with computer-executable instructions stored in a memory, hard drive, or other non-transitory storage of device for execution by a processor contained within. Also, the radio network controller  331  can be configured with a remote radio unit (RRU)  360  for downlink and uplink channel processing. The RRU can be configured to communicate with a baseband unit (BBU) of a base station controller  331  via a physical communication link and communicate with a wireless mobile device via an air interface. 
     In various alternate embodiments, the base station  338  can be separated into two parts, the Baseband Unit (BBU)  339  and the Remote Radio Head (RRH)  341 , which provides network operators to maintain or increase the number of network access points (RRHs) for the Node (gNB), while centralizing the baseband processing functions at a master base station  375 . Using a master C-RAN base station  375 , the power management system  370  can be instructed to coordinate operations in the tangent of power levels of multiple cells ( 321 ,  322 , and  323 ). 
       FIG. 4  illustrates an is an exemplary flowchart of the set of tests to validate a set of radio operations of a cell site at a post-construction stage, in accordance with an embodiment. 
     At step  400 , a mobile testing system validates certain radio operations at post-construction of a cell site by executing testing software to validate at least one operation related to a radio of the cell site. At step  405 , a receiver that is coupled to the processor of a handheld mobile device with the capability to capture at least one transmit sent in a radio downlink in a cell sector. At step  410 , a GPS service with the handheld mobile device is configured with the capability to determine positional information during the capture of a downlink transmit of the radio in the cell sector. At step  415 , the handheld mobile device causes the testing software to perform an analysis of the positional information and downlink transmits to identify the cell site by computation of directional angles derived from the downlink transmit. At step  420 , the handheld mobile device together with the testing software and a linked laptop have processing capability in part or together that is configured to measure at least one operation data related to the radio at the cell site for use to perform at least one radio operation test configured by the testing software to validate at least one radio operation at the cell site. At step  425 , the handheld mobile device, together with the laptop or in part, can perform at least one radio operation test configured by the testing software prior to commissioning in the operation of the cell site. At step  430 , the handheld mobile device performs at least one radio operation test configured by the testing software to validate the power-up of the radio at the cell site without the actuation of an alarm. At step  435 , the handheld mobile device performs at least one radio operation test configured by the testing software by operating the radio at the cell site at a minimal radio frequency to transmit a range of specified frequencies, to validate a measurement of a voltage standing wave ratio (VSWR) of the downlink transmit in a specified frequency. At step  440 , the handheld mobile device performs at least one radio operation test configured by the testing software to check whether a radio frequency connect that is landed at a port of an antenna configured at the cell site is correctly coupled without mismatch to a low band connection or a high band connection of an antenna. 
     At step  450 , the handheld mobile device performs at least one radio operation test configured by the testing software to validate a radio detection of a Remote Electrical Tilt (RET) angle configured with the antenna and for the operation of an e-tilt movement of the antenna through a normal range at the cell site. At step  455 , the handheld mobile device performs at least one radio operation test configured by the testing software to validate a signal to noise (SN) ratio of a RET angle configured with the antenna of a signal transmitted from the cell site. At step  460 , the handheld mobile device performs at least one radio operation test configured by the testing software of an assignment of a radio fixed physical cell identifier (PCI) of a band in the cell sector. 
     At step  465 , an app is configured on user equipment (UE) in communication with the cell site to receive the radio fixed PCI and the positional information; and the handheld mobile device performs at least one radio operation test configured by the testing software to validate a match of the app with the UE in the cell sector. At step  470 , the handheld mobile device performs at least one radio operation test configured by the testing software to compare an optimum value of a Reference Signal Received Power (RSRP) for each radio fixed PCI with the positional information in the cell sector to validate the integrity of a fiber connection by a fiber light level and radio frequency plumbing implemented at the cell site. 
       FIG. 5  illustrates an exemplary mobile handheld device (device)  10  with a testing application  15  in  FIG. 1 . The handheld mobile device  10  is depicted in a simplified block diagram representation of an exemplary embodiment of a computer-based device that supports the implementation of the testing application  15  with capabilities to monitor downlink transmission of a cell site  40 . The device  10  generally includes, without limitation: at least one processor device  502 ; at least one memory element  504 ; a touchscreen display  506 ; at least one communication (network) interface  508 ; a GPS module  510 , a receiver  512  capable of monitoring and listing to multiple different bandwidths of signals transmitted in a downlink from a cell site ( 40  in  FIG. 1 ), input and output (I/O) devices  514 , and capabilities to communicate via Bluetooth, cellular and wi-Fi. In practice, device  10  can include additional components, elements, and functionality that may be conventional or unrelated to the testing functionality described here. In this regard, device  10  can include a touchpad, or the like, instead of or in addition to the touchscreen display  506 , as well as a microphone for capturing audio. The touchscreen display  506  of a user interface component can be utilized with device  10  for actuating the client app (i.e., the testing application  15 ) for listening to transmitted downlink signals. In some instances, the user activation selection may be in the form of a physical actuation on the touchscreen display  506 ; in other instances, user activation may be triggered by natural language processing (NLP) of voiced user commands by applications of the device  10 . 
     The mobile device may include components of a processor  502 , for example, which may include a central processing unit (CPU), a field-programmable gate array (FPGA), a microcontroller, an application-specific integrated circuit (ASIC), or any other logic device or a combination thereof; a memory element  504  which is communicatively coupled to the processor  502 , and can be implemented with any combination of volatile and non-volatile memory. The memory element  504  has non-transitory computer-executable instructions (program code)  516  stored thereon, wherein the instructions  516  are configurable to be executed by the processor device  502  as needed. When executed by the processor device  502 , the instructions  516  cause the processor device  502  to perform the associated tasks, processes, and operations defined by the instructions  516 . Of course, the memory element  504  may also include instructions associated with a file system of the host device and instructions associated with other applications or programs. Moreover, the memory element  504  can serve as a data storage unit for the host device. For example, the memory element  504  can provide a storage buffer for audio packets or the like that are processed in part locally or note and are sent to a remote application server for further processing. 
     The touchscreen display  506  may be integrated with the device  10  or communicatively coupled to the device  10  as a peripheral or accessory component. The shape, size, resolution, and technology of the touchscreen display  506  will be appropriate to the particular implementation of the device  10 . The touchscreen display  506  can be realized as a monitor, screen, or another conventional electronic display that is capable of graphically presenting data and/or information provided by the device  10 . The touchscreen display  506  is communicatively coupled to the processor device  502 , and it can leverage existing technology to detect touch gestures and contact with a user&#39;s finger (or fingers), a stylus, or the like. In addition, the touchscreen display  506  is suitably configured to generate or otherwise provide activation control information that is associated with touch and force detected at the surface of the touchscreen display  506 . 
     The communication interface  518  of device  10  represents the hardware, software, and processing logic that enables device  10  to support data communication with other devices. In practice, the communication interface  518  can be suitably configured to support wireless and/or wired data communication protocols as appropriate to the particular embodiment. For example, if device  10  is a smartphone, then the communication interface  518  can be designed to support a cellular communication protocol, a short-range wireless protocol (such as the BLUETOOTH communication protocol), and a WLAN protocol. As another example, if the device  10  is a desktop or laptop computer, then the communication interface can be designed to support the BLUETOOTH communication protocol, a WLAN protocol, and a LAN communication protocol (e.g., Ethernet). In practice, the communication interface  518  enables the mobile handheld device  10  to receive media content for presentation on the touchscreen display  506 , wherein the media content can be downloaded, streamed, or otherwise provided for real-time (or near real-time) playback or for storage at the mobile handheld device  10 .
