In this practical case we will configure a long-range antenna with 14DBI and 300Mbps of download speed to establish a connection 3 km away and to have Internet at home with a neutral router. The model we have chosen is the CPE Melon 801 antenna which has a planar antenna or long range 14dbi panel, waterproof for outdoor and also powered by LAN network cable with PoE.

The CPE (Customer Premises Equipment) is a very versatile device because it can work interchangeably like router, AP access point, repeater or WiFi client. The choice of this WiFi CPE antenna model instead of a powerful USB antenna, has been done because it is about installing it on the roof in a tower located about 20 meters from the floor, where a conventional USB antenna does not arrive. When we want to reach a distance as long as 3km the location of the antenna is very important, it is obligatory that there is direct vision and that this at the same height as the transmitter WiFi and directed facing the other antenna.
In this case it is about sharing the Internet from a family home that is in a building 3km of the same height as ours and without barriers along the way. All we need is 2 CPE Melon 801 and a neutral router. The first CPE is placed on the roof of the family house that will emit the WiFi signal. The CPE will be set as repeater mode and the other in the building that will be configured as Client station mode (STA).


The CPE N801 is an ideal WiFi antenna to install on the roof as all circuits and antenna are integrated into a completely waterproof ABS plastic box and can be powered by an RJ45 network cable of 20 meters or more. The advantage of this cable is that at the same time you connect to the router that has Internet by the LAN port to transmit the signal from the router to the antenna, it also makes of electric feeder by means of the PoE system allowing the antenna to work on the roof fed of SDE the router.

The great power of this wifi PoE CPE receiver/transmitter makes it ideal for connecting to networks outside your home. Like for example to repeat a WiFi network of another floor or building, to connect to a public WiFi network of some park from house, to connect to the network of a familiar that lives near, to connect several plants of the same house, to give cover to a large farm or garden and much more that we or Curry using the three possible configuration modes:

-AP mode, WiFi transmitter, access point
-Repeater, bridge or repeater mode
-Client mode, WiFi receiver or station (STA)

This external WiFi antenna comes with a RJ45 network connector and two LAN and one WAN inputs/outputs. It is intended to be connected to any Router, both WAN (receive Internet) and LAN (Internet output) so its installation is simple and easy to configure.

The price is very affordable for the high quality of 14dbi planar antenna and the scope it has. Each unit can be purchased at 48 EUROS

1.-Connect the CPE Melon as a WiFi transmitter, reboot mode

The first step is to locate a LAN output of the router that has Internet in the house that we want to share. The Poe adapter plug is connected to the power supply and a cable from the router’s LAN output to the WAN input of the Poe socket. Then a cable is pulled as long as we need to the roof and connected from the WAN output of the PoE plug to the WAN input of the N801 antenna. This cable will give power to the antenna and will operate with a low consumption completely stable 24h. Of the day.

2.-Connect the CPE Melon as a receiver. Station or client mode.

This connection serves both to receive and repeat the signal of this example that is emitted by connecting to any free or open network that is available.
To receive a long distance WiFi signal we need this CPE N801 that will work as a powerful WiFi antenna for outdoor. It can be installed in the window, terrace or on the wall, but to work long distance to more than 500 meters and up to 3km it is important that this at the same height as the emitter and directed precisely towards that point.
This CPE has a multitude of functions, and when we install it as a WiFi receiver with client mode we can verify that we connect it by LAN output to a PC will give us internet immediately to that computer. In the same way if we installed it inside the house or in the window we can use the Repeater mode and while receiving by WiFi long distance will create a new WiFi network for all the devices that we need. But if we install it on the roof we can not use the Repeater mode because the WiFi network will not arrive if you have to cross several floors down. We remember that the WiFi signal can be easily transmitted in open spaces and horizontally, but with barriers and vertically will not reach our house.
In these cases it is recommended to install a neutral router inside the house that will receive the signal from the roof antenna by LAN cable and create a new WiFi network for the mobiles, computers and tablets that we need. For this work we recommend the OpenWrt neutral router for its great balance quality price, and the OpenWrt configuration interface in Spanish is very easy to handle.
In the case of each CPE Melon N801 is supplied with a POE device unit (Powerline Over Ethernet), this electric plug with WAN and LAN output is used to give power and network connection to the external antenna. To set up the antenna, connect the POE to a mains plug and a cable to the antenna and another to a computer. From the configuration interface of the CPE we choose the mode of use and we can write the password of the WiFi network to which we are going to connect. After saving the settings whenever you let’s light it will start working with that configured network.

3-How to configure the CPE Melon N801

To configure the external long-range CPE Melon N801 antenna, follow a few simple steps detailed in the manual. Once connected to the POE, and connected to a computer via LAN cable, we entered the Web browser and with the Web address http://10.10.10.254 we went to the configuration page and to configure the receiver WiFi we chose the client mode WiFi or Station (STA). Once configured we will have an Ethernet cable receiving the external WiFi connection. Then we can connect that cable to the neutral router to distribute it all over the house.

This long-range dual-polarization 14dbi antenna is capable of connecting to remote WiFi networks up to 3km with very good signal quality received, and also transmits to 300Mbps.


A CPE of these features has several modes of operation: AP/client/Repeater/AP Router/AP Client/Router (WISP). This means that you can use the antenna to connect two point-to-point antennas, to emit as WiFi hotspot access point, to bring the WiFi signal to another point, as a WiFi repeater from another router etc.

4-How a neutral router works to repeat the Internet.

When we want to install a WiFi router that distribute the signal throughout the house we need a neutral router, which is the one that cannot be connected directly to a line of ADSL or optical fiber, since it does not have built-in modem. To give the Internet to these router need to connect by WAN cable to a repeater or switch that has Internet. The neutral routers only work within an Ethernet network already established, as is the case of Launa antenna WiFi receiver by USB or a CPE.

The OpenWRT USB neutral router with 4 antennas 300Mbps silicon is a good option to repeat the Internet and create a WiFi network for the whole house. It has a WAN input and four LAN outputs. The new Mediatek MT7620 processor works with 64MB of RAM and 8 Mb of Flash memory.

This router can be connected to the CPE antenna by RJ45 cable. The neutral router repeats the connection caught in the street by the CPE Melon.

In this tutorial we have described the installation with the CPE Melo N801, but you can also make the same connection with the CPE nanostation LocoM2 of Ubiquiti. Ubiquiti CPE can also be used to link long-distance WiFI and are also compatible with the neutral Router.

To conclude we recommend this type of CPE to use them as receiving antennas for intermediate distances of 500 meters at 3 km because the PoE cable power allows a remote location of the house or office of the or that allow WiFi antennas by USB. If we want links to more distance like 5 km, 10 km or up to 15 km will be necessary the use of Yagi or parabolic antennas as explained in this other article of links WiFi long distance of up to 15km.
