The full English name of CPE is Customer Premise Equipment (CPE).
CPE customer terminal equipment is often deployed in the FTTX home customer service client, used to provide home customers with cable broadband, IPTV, VOIP and other services, integrated access. CPE uplink PON transmission network, the lower connection to the specific service equipment, to complete the connection between the access network and the user equipment.
Wireless CPE is a wireless terminal access device that receives wifi signals, replacing wireless client devices such as wireless cards. It can receive wireless signals from wireless routers, wireless APs, wireless base stations, etc. It is a new type of wireless terminal access device. At the same time, it is also a device that converts high-speed 4G signals into WiFi signals, but it needs external power supply, but it can support a larger number of mobile terminals at the same time.CPE can be massively used in rural areas, cities and towns, hospitals, units, factories, and neighborhoods to access the wireless network, and it can save the cost of wired network laying.
We always hope that the wireless coverage of the base station coverage the larger the better, but the transmission distance of the wireless system is also related to the technical indicators of the client terminal equipment. Standard WiFi clients have limited uplink power (generally 15dBm), no matter how much downlink power of the wireless coverage base station, the uplink distance of the standard WiFi client is limited by the uplink power, the distance is very limited. Wireless CPE is a dedicated client terminal equipment, using wireless outdoor CPE from the wireless coverage of the base station distance can be up to 4 times the standard WiFi client.
Of course, in the actual application, it is difficult to find a line-of-sight unobstructed application environment, through the wireless propagation model of the calculation and practical experience shows that the use of CPE client and base station transmission distance can reach 1Km-5Km.
