LTE is rolled out by Germany Telekom for two years. The first was in the city of Cologne in July 2011. In 2012, the 4G network plans are to go over 200 cities. On the body of the LTE Stick, there is the logo of Telekom. On the back is the exact name E398u-15, this is the second Revision of HUAWEI E398.  

  Compared to its predecessor, the stick is now finally LTE800 compatible. Therefore, users can surf via LTE in rural areas. Also, the LTE bands 2.6GHz and 1.8 GHz are supported. Speed Stick is the ideal USB datacard not only for urban use. With two integrated antennas (MIMO 2 × 2) and the support of up to 20 MHz bandwidth, the E398 can support up to 100 Mbps downstream and up to 50 Mbps upstream.  




A clear advantage over the Samsung GT-B3740 is the excellent backward compatibility with 3G DC-HSPA+/UMTS and 2G GPRS/GSM. If the 4G LTE network is not available, the stick can easily switch to the next available technology. There is a microSD slot that can be up to 32 GB for storage. Then the Surfstick could turn to a USB memory stick, for example for storing music, photos or other documents. The Speedstick LTE has two connectors for external antennsa. In areas of poor reception, the signal can be improved with the external antenna. According to the data sheet from Telekom, the device E398u-15 supports multi-mode network of mobile technology automatically. By the way, the firmware update function is also available in the mobile partner.   What’s more, the USB is rotatable for 270 degree, user can modify the USB angle to better fit for the computers.      


We recommend that the terms on a new contract at Telekom. This is much cheaper than buying without a term contract on If you don’t want a LTE stick with a contract, there is unlocked Speedstick LTE E398u-15, which could not only work with Telekom, it could also work with Vodafone and other 4G network providers in Europe and Asia.

Behind the Speedport LTE, it’s indicated that the model brand HUAWEI and model number B390s-2. The integrated LTE modem (4G) is only capable of the LTE band 20 (800 MHz). The Uplink frequency is 832-862MHz and downlink frequency is 791-821 MHz. The supported bandwidth is 10 MHz. So the router is uniquely determined only for rural use. The chipset "HiSilicon Hi6910" was installed.     Telephone:   Unfortunately, the router does not have a PBX. For Germany Telekom, this feature may be a disadvantage. Because in LTE tariff "Call & Surf via Funk "is an analog telephone port (optional ISDN) including fast network speed. So you need no additional hardware. LAN & WLAN:   For the construction of the home network, 4 LAN ports can be used at the LTE speed port B390s-2. If you prefer to connect wirelessly, user can rely on the WLAN standards IEEE 802.11 b/g, which allows up to 54 Mbit/s data transfer rate. The latest "N" standard is unfortunately not supported, nor as 5 GHz Wi-Fi. This should hopefully be supported with the upgraded model. The HUAWEI B593u-12 provides as significantly Higher speed to 100Mbps. And the encryption method can be chosen between WEP, WPA and WPA2 as usual.   Extra information:   The Telekom Speedport LTE is almost half as much as the technical, virtually identical to Vodafone B1000 4G Router. The weight is only 424 grams instead of 900 grams. The dimensions of the router are 195 x 169 x 64 mm (width x height x depth). Anyhow, it’s a reliable wireless router for building a home or office network.


HUAWEI E392 4G LTE Stick

The latest LTE stick E392 is from the Chinese manufacturer Huawei, as one of the most popular and best 4G modems, HUAWEI E392 is available for many operators worldwide. Based on reliable network compatibility, HUAWEI E392 is very good 4G Dongle for user. More about the strengths, key features and other relevant characters can be found below for E392 LTE Modem.

HUAWEI E392 Not available in Germany  


So far, Huawei is the major vendor for LTE and had supplied the major LTE network operators in Germany. Previously, HUAWEI had supplied the Speed Stick LTE for Telekom, and the K5005 for Vodafone, they are from the factory modem named Huawei E398. HUAWEI E392 is actually not a typo, it’s a newer model with a lower number than the older model E398.  The original HUAWEI E392 4G Stick (without logo of Vodafone or Telekom) so far is not available in Germany. Users could get it from . The compact USB stick is also LTE Category 3 USB Stick and could completely replace HUAWEI E398.      


The stick E392 supports casually pretty much everything that is common to worldwide radio standards. In LTE (4G), E392 stick supports the frequency bands 800, 900, 1800, 2100 and 2600 MHz. Here, in Germany rather LTE800, 1800 and 2600 are relevant. So the HUAWEI E392 could work with other European countries 4G networks. Also the 3G spectrum is almost completely covered. The E392 supports UMTS at 900,1900 and 2100 MHz in the standard DC-HSPA+/ HSPA+/ HSDPA and HSUPA. In the 2G networks users can access in the bands GSM 850/900/1800/1900MHz (Quad-band).


Based on the LTE technology, the E392 could transmit data with both FDD and TDD. These are two different duplex methods. For FDD (frequency division duplex), which is common in Germany, there are 2 separate frequency bands to use to send and receive data simultaneously. For TDD (time division duplex), the sending and receiving transmitted on the same frequency band, but slightly delayed. FDD is to be found mainly in Asia. E-Plus also experimented with the technology, and this could perhaps bring in the future for use in Germany.    



Anyone who uses a mobile LTE deal can theoretically explore the full power of the stick. This is a 100 Mbps stick for the download and it can be transmitted with a maximum of 50 Mbps. The HUAWEI E392 has provided two slots (MIMO) for connecting an external antenna. This often brings significant advantages in weak reception areas. The expandability via microSD card (up to 32GB) is now practically available. At just 40 grams of weight is also quite easy to take in hand or pocket.    




The Huawei E392 is the perfect travel companion based on the huge range of supported standards. Those who usually travel the world will never be disappointed.
