Streamlining Public Safety Network Design with Output Uplink Maps

Uplink capabilities are crucial in (P25, TETRA, TEDS or DMR) public safety networks. When first responders are in a potentially dangerous situation, such as firefighters inside a burning building, ensuring they can transmit information can be the difference between life and death. This makes uplink mapping a mission-critical requirement for all public safety wireless network designs.

Accurate mapping is necessary to ensure those uplink capabilities are reliable. Signals can be lost or diluted for a variety of reasons, all of which need to be identified in advance by sophisticated mapping tools capable of capturing the important nuances and performing the necessary calculations.

These calculations are highly complex and can be difficult for employees of Authorities Having Jurisdiction (AHJ – in the USA) or any other authorities in respectable countries and regions to interpret. Interpretation becomes particularly difficult when the data is packaged in traditional spreadsheet formats.

iBwave Public Safety resolves these issues with the addition of two new uplink output maps to the suite of previously released uplink maps, built on the foundation of the uplink-at-antenna map. Leveraging the uplink received signal strength indicator (RSSI) map added in the last release, the two new uplink automated gain control (AGC) and Near-Far Effect maps will make life easier both for designers and authorities by delivering three key benefits:

Simplified design process

More straightforward approval process

Accelerated implementation

RSSI Map Calculates Gain/Loss Anywhere in the Network

Manually calculating signal gain or loss is a highly difficult and complex task, requiring designers to account for gain or loss from hardware, including signal splitters, antennas, cables, and bi-directional amplifiers (BDAs), as well as from obstacles such as walls. Our uplink RSSI map performs these calculations automatically, displaying the cumulative gain or loss from all these network elements at any given point on the map.

Beyond the calculations themselves, the visual format of the map provides two key benefits. For designers, the visual representation is easy to interpret, which makes it easier to accurately assess the functionality of a network design. And since the maps are easily modified, they can quickly refine a network design as needed.

The visual representation also assists with the authorities’ approval process. Network design reviews are often done by staff who don’t have technical training, and network data historically has been in the form of dense, difficult-to-interpret Excel spreadsheets. Maps are clear and easy to interpret, ensuring the best possible chance of approval.

AGC Map Clearly Visualizes Gain Control

Gain control is a necessity for any wireless network. But it can affect the functioning of devices within that network, potentially causing some to not function. The new AGC map visualizes any gain control that will happen in a network.

This feature helps network designers address both overdesign and, crucially for public safety, under design. An overdesigned network is less budget efficient and is best avoided. But under design in public safety can mean the failure of mission-critical communications. This can be the difference between life and death for first responders or the people they’re helping.

Visualization makes it easy for designers to catch both overdesign and under design, while the easily modified maps make it straightforward to make adjustments and check them during the design process.

Near-Far Effect Map Captures Crucial Nuances

The near-far effect map shows when the proximity of one device to an antenna causes signal attenuation that affects a device that’s further away. When the signal strength gets modulated for the device closer to an access point, further devices in areas of poorer connectivity can lose their connection entirely.

Our near-far effect map captures this crucial nuance in public safety network design. Building off our AGC map, it gives designers the ability to accurately predict this more subtle cause of uplink failure.

And by presenting the information in a clear and comprehensive manner, it ensures the best possible chance of design approval by authorities. Rather than having to rely on heuristics, such as standardized antenna spacing that may not be relevant in a given deployment, an authorized employee can simply look at the map to see any potentially problematic areas. By avoiding dense, difficult-to-understand Excel spreadsheets, it minimizes the chance of misinterpretation of data.
