Recently, major media outlets reported that some shampoos contain carcinogenic dioxane, raising concerns about the hygiene of cosmetic products. According to the "Hygienic Standards for Cosmetics" issued by the Ministry of Health in 2007, dioxane (1,4-dioxane) is classified as a prohibited substance in cosmetics. The specific details can be found in Table 2, item 441 of the "Hygienic Specifications for Cosmetics." However, there are currently no regulations on the allowable levels of dioxane in raw materials, nor are there established testing methods outlined in the Cosmetic Hygiene Code. Dioxane, also known as 1,4-dioxane, is a colorless, slightly scented liquid with a density of 1.0329 and a refractive index of 1.4175. It has a melting point of around 11°C and a boiling point of 101.1°C. Dioxane is highly soluble in many substances and can be found in a variety of everyday products such as shower gels, detergents, moisturizers, marine fish, roasted chicken, meat products, tomatoes, ketchup, pepper, and coffee. Humans can be exposed to dioxane through skin contact, inhalation, or ingestion. Occupational exposure may occur via air, drinking water, or consumption of contaminated products, including cosmetics, topical medications, and agricultural or livestock products. Currently, dioxane is most commonly found in shampoos and shower gels. The State Food and Drug Administration emphasized in February 2007 that the Ministry of Health clearly defined banned substances in cosmetics regulations at that time. According to China's Cosmetic Hygiene Standards and Cosmetic Hygiene Regulations, any substance listed as prohibited cannot be used in cosmetic products. However, if a banned substance is introduced as an impurity during the production process, the final product must still meet the requirements of the Cosmetic Hygiene Standard and the Cosmetic Hygiene Specification. This means that under normal, reasonable, and foreseeable usage conditions, the product should not pose any harm to human health.

4G Outdoor CPE

Can you boost your WiFi signal with outdoor 4G CPE?

When you travel or go to some remote areas, you may be annoyed by poor reception. Is there any way to get a strong WiFi router signal outdoors in a 4G LTE network? Very good, outdoor 4G CPE router would be a good choice!

What is an outdoor 4G CPE router?
An outdoor 4G CPE router differs from a Wifi-only router in that it needs to be connected to a fiber optic network. The 4G CPE WiFi router can pick up the carrier's 4G LTE network signal and convert it into broadband and Wi-Fi. Just plug in your SIM card with your data plan and enjoy a stable and reliable WiFi signal with family and friends. This Outdoor CPE can be used in harsh environments. If you install your router outside or near a window in an area with a weak 4G signal, your device can receive a better 4G signal.

Second, what are the characteristics of outdoor 4G CPE router?
1. Better network for ODU and IDU
4G CPE outdoor routers include an outdoor unit (ODU) and an indoor unit (IDU). Help your device receive the best outdoor cellular signal through the ODU, and connect to the indoor WiFi router through the network cable to experience better network speed. As shown in the figure below, an outdoor LTE CPE (ODU) is installed outdoors and connected to an indoor Wi-Fi router (IDU) via a network cable. The entire 4G device is powered by POE. This data will be transmitted over the same Ethernet cable, eliminating the need to connect the ODU to a power outlet.

2. High-speed multi-user available
The outdoor 4G CPE features a built-in 4G LTE modem and a 5dBi high-gain antenna. LTE CAT4, download speeds up to 150Mbps, WiFi speeds up to 300Mbps, can connect 32 users at the same time. The high-gain antenna of the outdoor 4G CPE router enables it to have higher power and stronger signal transmission and reception capabilities than mobile phones. Therefore, the CPE router can receive the signal. If your phone can't receive a signal in some areas. Sometimes you also use your phone as a hotspot to share Internet access with your friends, right? Similarly, this 4G LTE CPE router allows 32 users to connect to WiFi at the same time, allowing more users to connect and receive a better signal than a phone sharing hotspot. In addition, the IDU has four Lan ports and can be connected to the device through network cables, which is also a backup mode of the Internet.

3. Excellent outdoor performance and design
On the one hand, outdoor LTE CPE is waterproof, UV resistant and corrosion resistant. It can be used at -20℃~60℃ operating temperature. Therefore, it is ideal for outdoor deployment. On the other hand, there are a variety of installation methods. CPE can be mounted on Windows or walls by mounting brackets. It is also possible to attach it to the antenna mast. In addition, the signal strength is displayed through the LED indicator to facilitate users to find the best location to get a better 4G signal.

4. Support different frequency bands
Outdoor 4G CPE supports a variety of frequency bands, including LTE-FDD, LTE-TDD, 3G WCDMA, and 2G GSM network bands. Meet the needs of different frequency bands in different regions and make full use of network resources.

5. Convenient management of CPE
Start the Web browser to log in to the Web management page. You can configure and manage the CPE easily. The web management system supports Linux. Provides functions such as WebUI management, Telnet, SSH terminal system status monitoring, NTP client, synchronization between devices and the system clock network, and configuration file import and export.

6. Applicable to various application scenarios
CPE is designed to provide ISP or operator with 4G LTE outdoor wifi router to facilitate network connection, whether at home, or in enterprises and remote areas, to bring users a wonderful network experience.

All in all, an outdoor 4G CPE router is an excellent choice for connecting to the Internet in remote areas and places where the signal is weak, the wired network is unreliable, or there is a lack of reliable WiFi. It's worth deploying outdoor CPE in rural, coastal, boat, caravan, campsite and remote areas to enjoy the best network speeds and outdoor activities! It can even reduce complex cabling deployments for home networks without the need to install a wired fiber network.
