CellOne LTE Neural Coverage – User Guide

Welcome to the BSNL internal GIS platform for visualizing and managing LTE network coverage. This guide explains all features available to you based on your user role (User/ Premium User).

1. Getting Started

After logging in with your Employee ID / email and password, you will see the main map interface. The screen is divided into:

Central Map – displays LTE sites (towers) as pulsating green markers, and Points of Sale (PoS) as distinct icons.
Right Tools Panel – contains interactive tools for queries, signal verification, navigation, and the Geospatial Reference Vector.
Left Statistics Panels – show live coverage statistics and band counts, with a Re‑sync Metrics button for deep data synchronisation.
Top Header – Logo, live clock, and a scrolling list of all active nodes.
User Controls (top right) – “Change Key” (password change), “TERMINATE” (logout), and for Premium Subscribers “Neural Access” (Admin Console Interface Window).
Footer – copyright, user badge, theme toggle (dark/light), and a session timer (for unsubscribed users).

2. Working with the Map

Site Markers

Each LTE tower is shown as a pulsating ☢ icon (default green). Click on any marker to see details: site name, frequency band, coverage radius, and technology (LTE/5G/UMTS/GSM).

PoS Markers

Points of Sale (retail/franchise) appear as different 🏪 icons. Click to view code, name, phone, and address.

Coverage Circles

Semi‑transparent circles around each site represent the theoretical coverage radius (configurable in admin panel).

Change Tower Color

Use the “Tower Color” drop‑down at the top right to switch marker colours: Default (green), Band‑based, Red, Blue, Yellow. Band‑based uses different colours for 700 MHz, 2100 MHz, and 2500 MHz.

Layer Controls

On the map you can toggle layers (sites, PoS, heatmap, drive test traces) using the standard Leaflet layer control (top left).

3. Right Tools Panel

All tools are accessible from the panel on the right side of the screen.

3.1 PoS Entity Query

Enter a unique PoS code and click “EXECUTE QUERY”. The map will zoom to that location and highlight the marker. If the code is not found, an error message appears.

3.2 Signal Propagation Verification

You can check which site covers a given geographic point and get an estimated signal strength.

Choose coordinate format: Decimal (e.g., 26.6175 93.9426) or DMS (e.g., 26°37'03"N 93°56'33"E).
Enter the coordinates and click “INITIATE VERIFICATION”. The system will find the nearest site and display the distance, site name, band, and an estimated RSRP value.

3.3 Real‑Time Navigation (with Audio)

Plan a route to any site directly from the map.

Start typing a site name in the “Enter site name” field – suggestions will appear.
Select the destination site.
Choose travel mode: Driving, Walking, or Bicycling.
Optional: check 3D (shows a 3D view), Live (traffic), or 🔊 (audio guidance).
Click “START NAVIGATION”. The route will be drawn on the map, and turn‑by‑turn directions appear in a panel. If audio is enabled, directions will be spoken.
Use “STOP NAVIGATION” to clear the route, or “Speak All Directions” to repeat the whole set.

Navigation requires an internet connection and uses Google Maps routing.

3.4 Geospatial Reference Vector (My Location)

This button (located in the right tools panel or as a map control) retrieves your current geographic coordinates using the device’s built‑in GPS. When pressed, the map centers on your location and displays a precise reference vector indicating positional accuracy. On smartphones with GPS enabled, accuracy typically reaches within 3–5 meters. The icon also shows real‑time satellite fix status and can continuously update your location as you move if continuous tracking is activated. This feature is essential for field verification, drive tests, and on‑site surveying.

4. Statistics Panels (Left Side)

Two panels provide at‑a‑glance information:

COVERAGE STATISTICS – Total sites, total PoS, total coverage area (km²), average site density.
LIVE STATISTICS – Counts per frequency band (700 MHz, 2100 MHz, 2500 MHz), last update time, system status (ONLINE).

Click “REFRESH STATS” to update the numbers from the database.

Additionally, the Re‑sync Metrics button performs a deep synchronisation of all statistical data with the central nexus. It recalculates coverage areas, band distributions, and site density based on the latest node configurations, ensuring that the displayed metrics are always aligned with the current network topology. This operation may take a few seconds and is recommended after any bulk changes or when discrepancies are suspected.

5. Admin Console (for users with Premium Subscription)

If you have administrator privileges, you will see a “Neural Access” button in the top‑right corner. Click it to open the full admin panel, which contains several tabs:

5.1 Sites Tab

Register new transmission nodes by filling in: name, latitude, longitude, frequency band, radius (km), power (dBm), and technology (LTE/5G/UMTS/GSM). Click “DEPLOY NODE” to save. The table of existing nodes allows inline editing and viewing on a map.

5.2 PoS Tab

Add new Points of Sale with unique identifier, name, phone, latitude, longitude, address, and type. Use “REGISTER ENTITY”.

5.3 Data Tools

Export Sites/PoS/All Data – download CSV files of the current database.
PoS Coverage Gap Analysis – enter a radius (km) and run analysis. The system will show which PoS are Covered, Marginal, or Gaps based on distance to the nearest site. Results can be exported.
PoS Distribution per Site (0‑5 km radius) – counts how many PoS are within 5 km of each site, helping to evaluate site importance. Export to CSV.

5.4 Heatmap

Configure and enable a coverage heatmap overlay. Choose band (All / 700 / 2100 / 2500), radius (px), blur, and intensity. Click “ENABLE HEATMAP” to render it on the map, “CLEAR HEATMAP” to remove it.

5.5 Drive Test

Upload a CSV file containing drive‑test logs (with at least latitude, longitude, and RSRP). The points will be plotted on the map with colour coding based on signal strength:

Excellent ≥ -80 dBm
Good -80 to -90 dBm
Fair -90 to -100 dBm
Poor < -100 dBm

After upload, you can generate a statistical report, export the data as CSV or GeoJSON, and clear the layer.

5.6 Microwave Link Budget

Calculate link parameters between two sites for backhaul planning.

Type in Site A and Site B (autocomplete works from the site database) or enter coordinates manually.
Fill in link parameters: frequency (MHz), Tx power, Tx/Rx antenna gains, cable losses, Rx sensitivity.
Click “CALCULATE LINK”. Results appear: distance, azimuth, free‑space path loss, received power, fade margin, earth bulge, Fresnel radius, and LoS clearance.
Click “SHOW ON MAP” to visualise the link in a separate popup map, or use the inline map for quick reference.

5.7 Bulk Coverage Analysis

Upload a CSV file with multiple locations to analyse coverage in batch. Map columns to ID, latitude, longitude, and set a radius. Results are summarised and can be exported.

5.8 System Tab

Displays database debug information (number of sites, first site details) and system metrics (total sites, total PoS, coverage area, last update). Use “REFRESH MATRIX” to update metrics.

6. Session Timeout & Subscription Plans

Normal (non‑admin, non‑subscribed) users have a 10‑minute absolute session timeout displayed in the footer as a timer. When the timer reaches zero, you are automatically logged out and your account is locked for 24 hours (cooldown).

To remove this restriction, you can subscribe to one of two plans (buttons appear in the footer and in the normal‑user modal):

Standard Plan – ₹500 / year: No timeout, but no admin privileges.
Premium Plan – ₹816 / year: No timeout + full admin rights.

Clicking a plan opens a Razorpay payment page. After successful payment, your session will be upgraded and the timeout removed.

7. Tips & Best Practices

Always click TERMINATE when you finish using the system – this clears your session token and prevents unauthorised access.
Use the theme toggle (moon/sun) in the footer to switch between dark and light mode according to your environment.
If you encounter any error messages, note them down and contact the system administrator with the exact text.
For drive test logs, ensure your CSV file has headers and at least three columns: latitude, longitude, and RSRP (in dBm). A sample format can be downloaded from the admin panel.
The microwave link calculator uses the Earth’s radius to compute earth bulge – results are approximate and should be validated with professional tools.
For best accuracy with the Geospatial Reference Vector, ensure your device’s GPS is enabled and you are outdoors with a clear view of the sky.

8. Troubleshooting

Map tiles not loading? – Check your internet connection. The map uses CartoDB tiles which require internet access.
Site autocomplete not working? – The site data must be loaded from the database. If the list is empty, contact admin.
“Database error” in admin panel? – Verify that the database tables exist and contain data.
Navigation not starting? – Ensure you have selected a valid destination from the suggestions. Also check the Internet Connectivity.
Cannot log in after reset? – If you are locked out, wait for the cooldown period to expire or ask a System Administrator to clear your cooldown.
My Location button not working? – Ensure location permissions are granted in your browser/device settings and that GPS is enabled.
