HELI Antennas with Circular Polarization for longer communication range and cost reduction
Connettività WiFi e Cellulare in GALLERIE e MINIERE
Le nuove Antenne HELI di Poynting a Polarizzazione Circolare offrono prestazioni tecnico economiche notevolmente superiori rispetto all’uso tradizionale dei CAVI RADIANTI per la copertura radio di GALLERIE e MINIERE
Alle frequenze superiori a 1 GHz le Antenne HELI a Polarizzazione circolare hanno dimostrato di fornire significativi vantaggi rispetto ai cavi radianti
Vantaggi delle Antenne a Polarizziazione Circolare per la copertura radio di GALLERIE e MINIERE:
> Intensità del segnale radio
> Riduzione delle interferenze da riflessione del segnale
> Maggiore efficienza di polarizzazione
> Maggiore efficacia nel superamento degli ostacoli
> Grande adattabilità ai diversi scenari di polarizzazione del segnale
e conseguentemente permettono di fornire:
> Comunicazioni più affidabili
> Migliore copertura in ambienti sotterranei
> Migliori prestazioni, affidabilità ed efficienza delle infrastrutture di comunicazione wireless in Gallerie e Miniere
> Migliore resilienza complessiva del sistema radio
Nel seguito un breve approfondimento di confronto
CAVO RADIANTE vs Antenne HELI a Polarizzazione Circolare
Leaky Feeder cables vs Helical Antennas
Leaky Feeder cables
|
Helical Antennas
|
| [+] uniform signal coverage in confined or irregularly shaped environments such as tunnels, mines, and underground facilities |
[+] well suited not only for open-air environments and point-to-point communication but also for confined or irregularly shaped environments like tunnels, mines, and other underground facilities |
| [+] the distributed nature of the leaky feeder system helps maintain consistent signal strength throughout the entire coverage area |
[+] their directional nature allows for more focused signal transmission and reception, resulting in a longer communication range |
| [-] leaky feeders have lower performance and reach on data-specific communication protocols like Wi-Fi or cellular (anything above 1 GHz) due to losses along the cable and after the signal leaves the cable |
[+] either vertical or horizontal polarization propagates better, depending on the specific tunnel dimensions: regardless of which polarization propagates better in a specific tunnel, the circular wave, with all polarizations, naturally adapts and ensures whichever polarization happens to propagate best gets to the other side more effectively, ensuring a larger reach and coverage |
| [-] linear polarization propagation varies greatly depending on tunnel dimensions and surfaces |
[+] Helical antennas may be designed for wide band deployments as required in modern 4G/5G networks |
| [-] generally exhibit lower signal strength compared to helical antennas due to signal leakage along the cable. Above 1 GHz, leaky feeders require too many in-line amplifiers to keep the signal at acceptable levels. These amplifiers require multiple points of power to be added along the tunnel and cause RF complications, such as noise in the system, failures that are not easy to detect, and poor C/I |
[+] Network expansion becomes easier, when frequency bands are ‘farmed’, changed or optimised. A wide band antenna is more future proof and prevents decommissioning of the old system to upgrade it for the new frequency bands (e.g., adding 3.5GHz) or the need to double up on the system and add a new leaky feeder for the specific frequency band |
| [-] generally narrow band, e.g., they work for 900MHz only or 900+1800MHz only |
[+] Helical antennas typically provide higher signal strength due to their focused and directional radiation pattern |
| [-] linear and single polarized, making it challenging to combat fading and polarization shifts |
[-] signal strength may vary depending on the antenna's orientation and distance to the transmitter |
| [-] leaky feeders offer no real MIMO benefit, as there is no polarization diversity and almost no spatial diversity, leading to lower bandwidths and higher latencies. At a time when 4x4 radios are becoming increasingly common, this puts significant constraints on system performance |
[+] more resilient when encountering obstacles such as locomotives and hauling machinery in a tunnel. Certain polarizations propagate better past these obstacles than others, meaning that circularly polarized antennas containing all polarizations ensure the best possible propagation past such obstacles |
And what's the best Antenna for your mobile Vehicles?
