MEDIATEK 7915 WIFI 6 DBDC MINIPCIE WI-FI MODULES in a Coach or Bus

524WIFI 6 MT7915 WITH IPQ4019/IPQ4029 5G RADIO ACHIEVE 843 MBPS THROUGHPUT | DBDC NETWORK CARD

The throughput of a network card refers to the data transfer rate or the amount of data that the network card can handle in a specific period. It is usually measured in bits per second (bps) or its multiples like kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps).

 The throughput of a network card is influenced by various factors, including the hardware capabilities of the card, the quality of the network cables, the network environment, and the protocols being used. Different network card models may have varying throughputs based on their design and capabilities.

 Modern network cards, especially those designed for high-speed networks like Gigabit Ethernet (1000 Mbps) or even faster, can handle data transfers at very high rates. The throughput of a network card is an important consideration in network performance, as it directly impacts the data transmission speed and overall efficiency of the network.

 It’s worth noting that the actual throughput experienced in a network may be lower than the maximum throughput of the network card due to factors like network congestion, latency, and other network bottlenecks. Network administrators often perform tests and optimizations to achieve the best possible throughput in their specific network setups.

MEASURING THE SIGNAL STRENGTH IN THE BUS

2.4 GHz antenna Huber & Suhner in the middle of the bus + 524wifi.com-AW7915-NPD

5 GHz antenna Huber & Suhner in the middle of the bus + 524wifi.com-AW7915-NPD

2.4 GHz antenna Antonics in the front of the bus + 524wifi.com-AW7915-NPD

5 GHz antenna Antonics in the front of the bus + 524wifi.com-AW7915-NPD

CONCLUSIONS FROM THE TESTING:


The test operations verified that the 524wifi.com-AW7915-NPD DBDC modules are usable in real situations and they are a full-fledged replacement for 2 Compex WLE900VX modules. The module was normally connected to 20-30 mobile devices. The signal strength on the device was in most cases up to 70 dBm.

Good>50 dBm
Normal50-70 dBm
Weak<70 dBm

For DBDC wifi operation, it is important to use an antenna for both 2.4 and 5 GHz frequency zones located in the bus area so that the signal covers all seats. When the bus is heavily occupied, two phenomena are happening at the same time:
1) Multiple devices are connected to the module
2) There is a deterioration of the spread of the RF signal (the human body acts as a signal shield)
The main advantage of using DBDC modules is the reduction of the number of antennas and cables by half. Which brings significant savings and simplifies installation. The disadvantage, on the other hand, can be a bit less coverage of the bus space because of smaller antenna amount.

In OPENWRT you need to set up read RF parameters from eFuse. Kindly be noted.
