The Difference Between 4G LTE Gateway and CPE

What is a 4G LTE Router?

The term 4G is an abbreviation for the fourth generation of mobile communication and its corresponding technology. According to the International Telecommunication Union (ITU), any wireless data network system capable of achieving or exceeding 100 Mbps qualifies as 4G.

The full name of LTE is "Long Term Evolution," which denotes a significant advancement in mobile communication. LTE operates in two duplex modes: FDD LTE and TDD LTE. It notably enhances spectral efficiency and increases data transmission rates, with peak rates reaching 50 Mbps for uploads and 100 Mbps for downloads. When compared to the 3G era, where the downlink peak speed was only 10 Mbps, LTE offers a tenfold increase in speed.

From these definitions, it is clear that 4G and LTE are not identical. However, generally speaking, LTE networks meet the standards for 4G networks, as they can offer downlink speeds of 100 Mbps. Consequently, the 4G era is predominantly characterized by LTE networks, leading to the common reference of both as 4G smart routers.

4G CPE and LTE

4G CPE is an LTE data terminal device that converts high-speed 4G signals into WiFi signals. This allows multiple mobile terminals to connect simultaneously. 4G CPE devices are extensively used for wireless network access in rural areas, towns, hospitals, factories, and communities, thereby reducing the costs associated with laying wired networks.

On the other hand, a 4G LTE gateway is an integrated intelligent gateway that combines the functionalities of CPE, voice gateways, and wireless routers. Users can connect POTS phones, PC soft terminals, or SIP phones to the CM-IMS via the TDD-LTE gateway for voice services. Additionally, PCs or mobile devices can access the Internet through the LAN port or WiFi interface for data services. The 4G LTE gateway primarily targets users in remote branches of enterprises, cluster stores, and chain stores that require LTE coverage.

The Difference Between 4G CPE and 4G LTE Gateway

1. The 4G CPE can only connect through the operator's wireless network, whereas the 4G LTE gateway also supports wired connections (the 4G LTE gateway is equipped with one WAN port). The dual access methods of the 4G LTE gateway enable link hot backup functionality. For instance, when the 4G LTE gateway serves as a voice access device, if the dedicated voice line linked to the WAN port fails, the device automatically switches to the LTE wireless network to register on the IMS platform, ensuring continuity of voice and data services.

2. The downlink interfaces of 4G CPE only include WiFi and LAN ports, which limit the network access capabilities for users. However, many businesses require connections for financial POS machines, fax machines, landline phones, and other devices, which traditional CPE cannot accommodate. In contrast, the 4G LTE gateway adds two RJ11 analog interfaces to fulfill the functional gaps found in 4G CPE devices.

4G / 5G - Huawei CPE Pro Vs B618

* The best speed test that my router managed was 237 Mbps Down / 105 Mbps Up.
* Latency is generally around 40 ms. Services like GeForce NOW perform variably on Huawei's router; however, it streams 4K videos (YouTube / Netflix / Plex) without issues.
* My connection is surprisingly stable, with Docker containers programmed to alert me or attempt to restart if the connection is lost. They have maintained 18 days of uptime without incidents.
* The WiFi signal sufficiently covers my entire flat, but I have noticed some extra latency on the 5GHz band. My single "WiFi 6" client achieved speeds of over 100 Mbps while downloading from my NAS. Unfortunately, I couldn't utilize the 160 MHz channel, and even 80 MHz channels are somewhat unstable where I live. Setting the maximum channel width to 40 MHz and carefully selecting channels significantly improved latency.
* With only two Ethernet ports available, I purchased a switch and connected 8 clients without issue. The router can handle over 15 clients effortlessly.
* The Router's Mobile Admin App is not user-friendly and requests excessive permissions, so I would avoid it.
* This might be specific to EE, but my devices were assigned only IPv6 addresses by default, disrupting several services. I had to change APN settings, enforce IPv4, and use custom DNS to resolve the issue.
* Furthermore, with EE, I couldn't expose internal ports to the internet, even while using IPv6 addresses and fully disabling the router's firewall.
Overall, I am very satisfied with the CPE Pro; it has exceeded my expectations and is one of the best options available while waiting for 5G.
