First impression


Coming from the original Huawei model E5186 LTE CPE, the Telekom presented the series as usual in noble black. On the back there are only 4 gigabit ports. The front informs with four LEDs information about “Power”, “Mode”, “wifi” and signal. A configuration of the router can be done directly through the browser. The right flank of the router has a WPS and Wi-Fi button, and a reset button. The SIM card slot is on the top right place.




Anyone looking for a new, high-performance wireless router, gets an attractive solution with the new device Speedbox III LTE from Germany Telekom. The Speedbox LTE III supports LTE Advanced with up to 300 Mbit/s download speed (50 Mbit/s upload speed) and the latest WLAN standard by 802.11ac. This transmits at 2.4 GHz and 5.0 GHz. With the LTE frequency bands 800/900/1800/2100 MHz and 2600MHz, a wide range is covered. The external antenna connector is actually hiding at the back behind a small cover to find. The box can bring the network for up to 64 Wi-Fi enabled devices.




The Speedbox LTE III is technically based on the Huawei E5186 4G Router, however, still there are some differences between them. The E5186 LTE CPE also called E5186s-22a indicates the modification. The original E5186 has two RJ11 connectors and a USB port of the standard 2.0 interface. The software (firmware) is different and you will find a logo of the network operator on the front. In addition, the front lacks the “Voice” Info-LED.




The DECT or analog telephone is not supported. If you want the function, probably you should choose the Vodafone B4000 or Huawei E5186 original model. And VOIP will not be a problem.  The send and receive short messages (SMS) via the Speedbox LTE III is actually possible.





Since September 2014, the Speedbox LTE III is available on the Germany Telekom, and now the unlocked Speedbox LTE III is also available on . And the price is certainly reasonable for the first CAT6 router. The package includes a power adapter, an RJ45 LAN cable and a Quick Start Guide. If you want to change your 3G Router to 4G, the Speedbox LTE III should be a good option. If you want to get the full functions of the 4G Router, huawei original E5186 should be better to choose.
