Huawei CarFi E8377 Hotspot Test

A Wi-Fi hotspot in the car - this feature is so far available only for a few cars of the upper middle class and upper class. Huawei changed the cigarette lighter connector for new Carfì hotspot for 12V. Users can reach up to 150 MBit/s via LTE through the Huawei Carfì Hotspot, of course, the CarFi can also a fallback to 3G and 2G. But the Carfì wireless router is really as good as the expensive installation solutions from car producer? In this test, we find out the answer.



Appearance and Technology

Huawei Carfì Hotspot is conducted under the Model Number Huawei E8377 and comes in a nice package for buyers. The scope of supply is tight, next to the hotspot itself there is  a Quick Start Guide, a brochure with safety instructions and an indication of the Huawei HiLink app included. The Huawei Carfì Hotspot is kept in a matt black plastic and the front is equipped with a carbon look, which is likely to look smart in almost any car. On the front there is also the power button, which simultaneously serves as an indicator of the reception strength by the underlying LED. A yellow LED indicates poor UMTS / LTE receiver while a green LED indicates good reception.



Of course, you need a SIM card with the appropriate data plan for the operation of Huawei Carfì. The card must be in micro-SIM format and is inserted under the side cover in the Carfì hotspot. Under the cover you will find also a reset button and a connector for an external antenna. There is a integrated rechargeable battery; so user can operate Huawei router Carfì in the car and can take the CarFi in a meeting or outdoors.



The maximum speed in the LTE network is 150 Mbit/s over LTE Cat4. According to Huawei, the Huawei CarFi supports frequency bands by 800/900/1800/2100/2600 MHz. If no LTE times are available,  you can also use 3G (up to 42.2 Mbit/s) and 2G. In the test of the handover between the different network technologies, Huawei CarFi can work smoothly while driving. The reception is in both LTE and UMTS, but no better than most smartphones. Those who expect a good reception will be disappointed by Huawei Carfì or possibly should directly connect an external antenna.

The wireless module operates on the 802.11 b/g/n, ie on the frequency band around 2.4 GHz. The area around 5 GHz is not supported. The signal is strong enough to cover larger cars.  


Control via App


Once you have the Huawei Carfì Hotspot connect it to a cigarette lighter connector, it must be turned on manually before use each time. Before first use you should write down or take a picture of the WLAN key, because as soon as the device is plugged in, it’s different for to read the key. Also, one should previously load the Huawei HiLink app to Android or iOS device, because that is for the establishment and the operation.



Connection parameters like APN or access numbers can’t not be stored. The Huawei Carfì can automatically recognized the SIM card from Vodafone and Orange in the test and the data stored accordingly. Only the PIN code must be entered, if enabled. The Huawei HiLink app allows various settings, for example, you can configure the name and password of the WLAN network. A wireless guest network with a separate name and password can be set up, ideal for guests in the car or for taxi drivers.



Connection information such as data consumption, connected wireless devices and the online time are displayed graphically in the app. The firmware of Huawei Carfì can easily be updated online. A major disadvantage of Huawei HiLink app: the test with Android smartphones, the program fell on extremely high energy consumption. Here Huawei should urgently provide an update for Remedy. In the test, we can find Huawei Carfì has two major disadvantages: firstly, the device must be turned on every time manually, if you want to use it, a start on some cars are not possible, at least for a VW Golf VI, a Ford Galaxy and a Renault Scenic. Second, only the internal antenna is used in the hot spot, whereas fixed-mounted solutions always use the external antenna, thus naturally have much better reception conditions. Nevertheless, the Huawei Carfì Hotspot is recommended as a retrofit solution definitely, because all the promised features are well met. Of course, you could also have a mobile wireless router with battery, the Carfì Hotspot is significantly more convenient.


Huawei Announced P8 P8 Max and P8 Lite

Huawei has announced the P8 series smartphone in London. In addition to the Huawei P8, which is the flagship device of the series, there will be a Huawei P8 Max with greatly enlarged display and a Huawei P8 Lite with stripped-down functionality. The Huawei P8 waived first time to lure the customers with various highlights. So far the quality of the camera is so far consistently praised in glowing terms and also Huawei has seemingly done everything right for the P8. The P8 is clear as Huawei P series device, since the design was little changed compared with the previous Ascend P7. Overall, the body is high-grade and almost completely made of a metal block.



Huawei P8

The Huawei P8 comes with a 5.2-inch display with full HD resolution, and the operating system is Android 5.0 Lollipop including Huawei EMUI 3.1 interface. The camera is one of the highlights as I said; it has a resolution of 13 megapixels, features an optical image stabilizer and is in spite of the very small dimensions. A special camera function, for example, the possibility of photos exposing long, thus allowing for light-effects such as "Light Painting". Videos can be recorded at up to 1920 × 1080 pixels (Full HD). The internal memory is 16 gigabytes in size, and can be expanded via microSD card.   The processor of Huawei P8 uses a Kirin 930 from the house HiSilicon, which has about 8 cores. Four of them have a maximum clock speed of 2.0GHz, the other four are working with a maximum of 1.5 GHz. It’s very disappointing for the P8 flagship device that wireless only supports in the frequency range of 2.4 GHz (Wi-Fi 802.11 b/g/n) and LTE is in Category 4, and around 150 Mbit/s in the downlink is limited. From network suppliers such as Huawei, one might have expected LTE Cat6 and WLAN ac, especially since this is an absolute standard in 2015.


Huawei P8 Lite


The Huawei P8 Lite is only half as expensive as the big brother Huawei P8, but still offers good facilities and a similar design. With dimensions of 143.0 x 70.6 x 7.7 mm, it is quite compact, considering that on the front, a 5-inch display with a resolution of 1280 x 720 pixels is installed. Huawei P8 Lite can support 16 GB of internal memory with a microSD card to expand. The camera triggers with 13 megapixels like its big P8, is likely to be different from the picture quality.



The Huawei P8 Lite comes with a HiSilicon Kirin 620 processor, which has eight cores with 1.2 GHz and offers 2 GB of memory. Huawei P8 Lite is on board LTE Cat4, so that speeds of up to 150 Mbit/s can be achieved through LTE. Whether the wireless networkof P8 Lite is also limited to 2.4 GHz, has not been announced in the press release.


Huawei P8 Max


The Huawei P8 Max is the big brother of the P8, we suppose it would be available in Europe soon. The two biggest differences to "normal" Huawei P8 are the larger display (6.8 inches instead of 5.2 inches) and the significantly stronger battery with 4360 mAh. The Huawei P8 Max also supports LTE Cat6 with up to 300 MBit/s in the mobile network, so the connection speed is twice as fast as the normal P8. Also WLAN ac to 2.4 GHz and 5 GHz are supported.



The processor of Huawei P8 Max comes with the HiSilicon Kirin 935, the 3 GB RAM are aside. The internal memory is 64GB in size and can be expanded via MicroSD. Unfortunately, the display is in spite of its huge size of 6.8 inches, "only" equipped with FullHD resolution, here if equipped with a QHD resolution, it would have been quite timely.



Huawei CarFi E8377 LTE Router Review

In the last few years, it’s the main trend to connect cars. Internet access in the car or camping Mobile is still reserved for the premium class. However, new wireless gadgets provide solution. The Huawei E8377 specially designed for the motor vehicle provides the first use and inexpensive hotspot router with LTE. We have tested the "Huawei Carfì Router" for you and share the details below.



With the Carfì E8377 router, user can access internet via the mobile Wi-Fi hotspot. The CarFi could work on 3G or 4G LTE and up to 150 Mbits per second download speed are possible here. The concept is not entirely new. Huawei had brought a car Stick named W5101 for the first time to the market. It’s available for Vodafone contract. But it’s an ordinary USB stick, which was connected via an adapter into the cigarette lighter. The E8377 Carfì could connect to the card through the cigarette power connector, which is a direct solution for wireless network.



The packaging looks quite classy and looks like a clock-bell. After opening the box, there is only a mini-manual next to the device. In addition, a tiny leaflet-list is available for installation. The user manual (sweet 6.5 x 5 cm) available in several languages and there are short Tips for settings.



The egg-shaped head of CarFi E8377 gives only a start switch, a notification LED and laterally a SIM card slot (Micro SIM) together with the reset button. Directly to the head connects to the cigarette 12-volt port. From a processing perspective, the device is "appropriate". The specially adapted to use in the car shape design, the E8377 hardly looks like a foreign body in any case. Now, let's consider technical data. The mobile module initially supports LTE in all major bands at 800, 900, 1800, 2100 and 2600 MHz. Thus, the Car-stick can easily use in Europe. Based on the LTE Cat4 modem, it can reach up to 150 Mbps for download and up to 50 MBit for upload in connection with a matching LTE tariff. In addition to LTE/4G, the CarFi still has support for more mobile phone standards. Among them are as UMTS 900 and 2100 MHz 3G Turbo DC-HSPA+ (up to 42 Mbps) and 2G (GSM, EDGE, GPRS). So even in very poor regions with weak signal, user can still have the chance of a slow connection. The WLAN module supports 802.11 b/g/n and thus can provides data rates up to 300 Mbps.  



The router Carfì measures 5.9 x 4.9 x 8.8 inches and weighs only 50 grams according to the manufacturer. However, our weight measurement yielded 146 grams. Huawei will also indicate that the E8377 has an integrated battery, which has a capacity of 1900 mAh. However, we were able to connect Carstick for long hours of use on the current port, without connecting the CarFi to the cigarette slots. Thus, we believe that the battery only serves to maintain the operation as soon as the energy source is gone suddenly.



A USB port is located on the side. This port is not a data interface, but as a kind of adapter. Huawei has considered that many people use the car's cigarette lighter as a charging station for mobile phones and other devices, when the cigarette port is used. No more space will be available without adapter for third-party devices. Through the USB port on the side, you can now connect there and load it. Beside the SIM slot, there is a TS9 connector for connecting an external antenna. However, only 1 port, users have to give up 2x2 MIMO. But at least there is a possibility! It is precisely when traveling, for example with a camper, the reception is weak and need external antenna. To make user understand well about the color shining in Huawei CarFi, here are some codes about the colors:

  • * Flashes red: Indicates that the Carfì is started. Takes about 20 seconds;
  • * a steady red light: Indicates that no wireless network is found, or the connection was not possible (eg missing SIM);
  • * lights up yellow: Indicates that the signal strength for 3G or LTE is very weak;
  • * green: reception strength is optimal;
  • * Flashing cyan: There is just a firmware update;
  • * White: Indicates unread SMS exist.


Installation and Settings

Theoretically, the installation of the E8377 is easy and should be done in less than 3 minutes. First, the SIM card must be inserted. The slot is located under a cover with SIM icon. Then plug the Carfì directly into the cigarette lighter of your car. Turn the ignition so that a power supply is present and press the "Huawei" button on the top for a good 3 seconds. Now the border should first turn red - the CarFi router will start and automatically connects to the wireless network. This takes about 20 seconds. Now you can search the wireless SSID of CarFi E8377 in a laptop, tablet or smartphone. This begins with "Huawei CarFi-". Both SSID and the wifi key are listed at the foot of the plug. Enter this key or scan the QR code on request with your smartphone. The WLAN connection to Carstick should now be finished. If there is a cellular connection via 2G / 3G or 4G, surfing internet is possible in the way. And up to 10 devices in and around the car could access to the internet.  

Huawei provides a special HiLink App for smartphone and tablet users. This can (if no network) are downloaded directly to the internal memory as required from the PlayStore or AppStore. The app provides information about the connection status, for example, the signal strength, currently used wireless standard and data usage.


Practice test


We have tested the car stick several hours on the road. The installation went really smoothly. Before setup, user must know the color code, otherwise you do not initially know what that mean the color feedback. In mobile reception there is nothing to complain about. This is comparable with other sticks. You should wonder the connection speed in remote areas. Frankly speaking, the speed is just decent, but this problem can be solved by an antenna that is mounted with enough cable on the roof through the window.




Huawei E8377 Carfì is ideal for those who spend hours on the car and where several inmates want to access the Internet.  The installation and handling is simple and straightforward. However, there is currently no better alternative for the car. If you want to have wireless network around in camp or have activities in a car, Huawei E8377 would be a perfect partner.
