IPQ6010 AND IPQ8072:OFDMA SUPPORT IN WIFI6 SOLUTION

Introduction:

In the dynamic landscape of wireless communication, the techniques employed play a crucial role in optimizing data transmission and overcoming challenges. Two key technologies, FDMA (Frequency Division Multiple Access) and OFDMA (Orthogonal Frequency Division Multiple Access), are pivotal in this context. This blog aims to unravel the disparities between FDMA and OFDMA, shedding light on their applications and significance in mitigating multipath interference, particularly in the realm of Wi-Fi.

The Need for Multiple Carrier Technologies:

To comprehend the essence of OFDMA, it’s imperative to first delve into the concept of OFDM (Orthogonal Frequency Division Multiplexing). OFDM is a multicarrier modulation technique designed to combat multipath interference encountered in wireless communication. Multipath interference occurs when radio waves encounter obstacles, causing reflections and refractions. This phenomenon results in multiple versions of the same signal reaching the receiver, leading to what is known as multipath interference.

The Challenge of Inter-Symbol Interference:

Multipath interference directly contributes to intersymbol interference (ISI). In the realm of wireless communication, ISI poses a challenge where, for a given set of serial signals, the receiver encounters difficulty distinguishing between them. This challenge arises when the time delay between two identical signals is less than the signal’s transmission interval. The outcome is known as inter-symbol interference, making it arduous for the receiver to accurately decipher the intended signals.

OFDM as a Solution:

OFDM addresses this issue by transforming high-speed serial data into parallel low-speed data streams, thereby reducing inter-symbol interference. However, OFDM comes with its own set of drawbacks. In Wi-Fi 4/5, where communication is single-user-centric, each data transmission occupies all available subcarriers. This results in inefficiencies when small data packets, such as instant messages or web browsing, are transmitted, as the entire bandwidth is underutilized.

Introduction of OFDMA:

In response to this inefficiency, Wi-Fi 6 introduced OFDMA, borrowing a page from 5G’s playbook. OFDMA, despite its name’s resemblance to OFDM, is fundamentally a multiple access technique. Multiple access techniques distinguish different users, and common methods include FDMA, TDMA, and CDMA.

FDMA vs. OFDMA:

FDMA relies on allocating different frequency channels to different users. In the analogy of a gathering, it’s akin to separating rooms for distinct conversations. On the other hand, OFDMA divides the channel into Resource Units (RUs), each orthogonal to the others. In our gathering analogy, OFDMA creates individual compartments within a room, facilitating multiple conversations simultaneously.

Enhancing Efficiency with OFDMA:

OFDMA optimizes spectral efficiency by scheduling users in specific resource units instead of utilizing the entire channel for a single user, as seen in traditional OFDM. It introduces a more flexible approach, akin to efficiently utilizing a delivery vehicle by allocating designated compartments for different recipients.

Conclusion:

In summary, while OFDM successfully addresses multipath interference by transforming data streams, OFDMA takes a step further by introducing an innovative multiple access technique. By adopting OFDMA, Wi-Fi 6 has elevated efficiency in point-to-multipoint communication, ensuring that a single cycle completes communication with multiple users. This evolution underscores the dynamic nature of wireless communication technologies, continually adapting to enhance performance and meet the demands of evolving applications.

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.
