Ii. Supports WiFi6: A Wireless Experience for the Future
To meet the growing demand for high-bandwidth applications, ComFi C22 4G Cat4 router /CPE prospectively Supports WiFi6 (802.11ax) technology. Compared with the previous generation of standards, WiFi6 has made a qualitative leap in speed, capacity and latency. For a 4G Cat4 router /CPE, supporting WiFi6 means it can not only efficiently receive 4G signals but also distribute the network to multiple terminal devices in a more advanced way. Whether it’s 4K/8K ultra-high-definition streaming media, online cloud gaming, or video conferencing, ComFi C22 4G Cat4 router /CPE can offer smoother and more stable wireless connections, bringing users a future-oriented network experience.
Iii. 300Mbps Wireless Speed: The Promise of High Speed and Smoothness
ComFi C22 4G Cat4 router /CPE can provide a Wireless transmission rate of up to 300Mbps Wireless Speed. This speed metric is the key to measuring the performance of a 4G Cat4 router /CPE. It ensures that high-speed data downloaded from 4G networks can be distributed lossless and with low latency to users’ mobile phones, laptops, tablets and other devices via WiFi. Whether it’s downloading large files, watching high-definition videos, or processing multiple tasks in parallel, ComFi C22 can handle them all with ease, eliminating lag and buffering, and fulfilling the promise of a high-speed and smooth network.
Four. High Band Capacity: Handle the challenges of multiple devices with ease
In modern home and office environments, the number of networked terminals such as smart phones, tablets and smart home devices has soared. The ComFi C22 has an outstanding High Band Capacity, which is attributed to its advanced chip and WiFi6 technology. As a centralized 4G Cat4 router /CPE, it can stably connect dozens of devices simultaneously. When multiple devices are connected concurrently, it intelligently schedules network resources to avoid network congestion and ensure that each device can enjoy a smooth Internet experience. This is crucial for smart homes with numerous devices or small team offices.
V. Powerful Chip: The Core Engine for Stable Operation
Behind all outstanding performance lies a powerful heart. The ComFi C22 is equipped with a high-performance Powerful Chip. This highly integrated SoC chip serves as the “brain” of the entire 4G Cat4 router /CPE, responsible for handling all complex tasks such as 4G signal demodulation, data forwarding, and WiFi signal processing. The powerful processing capacity ensures that the equipment can still operate stably under long-term high-load conditions. Meanwhile, its high-efficiency design also guarantees lower power consumption and heat generation, providing a solid guarantee for the long-term reliability and durability of the product.
Vi. Strong Signal: Quality Assurance for Full-link Connection
The stability of the connection depends not only on the speed but also on the signal quality. ComFi C22 has made great efforts in Signal reception and coverage, achieving dual guarantee of Strong Signal. At the receiving end, it is equipped with a high-gain 4G antenna and advanced signal receiving algorithms, which can capture weaker 4G signals and maintain a stable connection even in the edge areas of signal coverage. At the transmitting end, its optimized WiFi antenna design ensures wide coverage and strong penetration of wireless signals, eliminating signal dead zones in the home. This Strong Signal optimization from the outside in is a manifestation of the quality of ComFi C22 as a top-of-the-line 4G Cat4 router /CPE.

Supports WiFi6

In the field of wireless local area networks, technological iterations are advancing at an unprecedented pace. While many similar 4G Cat4 router /CPE products still adhere to the WiFi 5 (802.11ac) standard, ComFi C22 has proactively adopted the latest WiFi 6 (802.11ax) high-speed wireless module. This decision enabled it to stand out among numerous competitors and brought about a qualitative leap for users.

The core advantage of WiFi 6 lies in its introduction of revolutionary technologies such as OFDMA (Orthogonal Frequency Division Multiple Access) and MU-MIMO (Multi-User Multiple-Input Multiple-Output). For a 4G Cat4 router /CPE, this means that its internal wireless resource scheduling capability has been unprecedentedly enhanced. OFDMA technology enables routers to simultaneously transmit data packets for multiple devices within a single time window, much like an efficient bus that can carry passengers to different destinations at the same time, significantly enhancing network efficiency and reducing latency under high-density device connections. This is crucial for scenarios in modern households where dozens of smart terminals such as mobile phones, tablets, laptops, smart TVS, and vacuum cleaners are online simultaneously.

The MU-MIMO technology further optimizes the mechanism of concurrent communication among multiple devices. Traditional routers can only communicate at full speed with one device at a time, using a “time-sharing multiplexing” approach to provide alternating services. The more devices there are, the shorter the “time slice” each device is allocated, and the more sluggish the network naturally becomes. The WiFi 6 module of ComFi C22, through MU-MIMO, can establish parallel data streams with multiple devices simultaneously, just like having multiple arms, ensuring that each device can obtain stable and high-speed bandwidth, and completely bid farewell to the predicament of “one person using the network, the whole family lagging”.

Therefore, when the ComFi C22 4G Cat4 router /CPE acquires high-speed data from the wide area network through its 4G Cat4 module, its built-in WiFi 6 module can distribute these data losslessly to every corner of the home in the most efficient and stable way. This not only means that “network speed is not compromised”, but also represents that in a complex environment with high load and multiple concurrent devices, signal transmission remains “high-speed and stable”, and the connection experience is “as smooth as silk”. Choosing the ComFi C22 that supports WiFi 6 means investing in a more forward-looking 4G Cat4 router/ CPE that can better meet future challenges for your digital life.

300Mbps High-speed Internet Access

As a 4G Cat4 router /CPE, its fundamental performance depends on the capabilities of its cellular network module. ComFi C22 strictly adheres to the 4G Cat4 standard, which means it can achieve a downlink peak rate of up to 150Mbps and an uplink peak rate of 50Mbps. Through advanced carrier aggregation technology, the wireless transmission speed of ComFi C22 in practical applications can reach an astonishing 300Mbps. This rate is comparable to many mid-to-low-end fixed broadband services, providing users with a true “wireless fiber optic” experience.

What does a 300Mbps bandwidth mean? It means you can watch 4K ultra-high-definition online videos smoothly without having to endure annoying buffering. It means you can hold high-definition video conferences with clear pictures and synchronized voice, doubling the efficiency of remote work. It means you can play online games freely at home, and the low-latency network response gives you an edge in the virtual world. It also means that family members can simultaneously carry out their own high-bandwidth-consuming network activities without interfering with each other.
