Huawei MS2372 — LTE Stick for the Industry

USB surf sticks with LTE modem were the first devices for the first LTE networks in 2011, with which you could use the new mobile network of the fourth generation. In Europe, for example, the Samsung GT-B3740, Huawei E392u-12 and the Huawei E398 were widely used. In the meantime, at the end of 2017, LTE surf sticks in the end customer sector hardly play a role anymore. Most customers want to use a LTE hotspot with WLAN and battery for mobile use and a “real” LTE router with LAN and WLAN function for stationary use as a DSL replacement. For industrial applications, Huawei now presents a new LTE stick: Huawei MS2372.

 

Huawei MS2372 Applications

According to the manufacturer, the Huawei MS2372 LTE USB dongle can be used, for example, in mobile sales terminals, in vending machines, in consumption meters or in medical device. These devices require a connection to the Internet for a variety of reasons and can be upgraded with the LTE Stick as needed. For example, a remote update of certain devices is possible or a vending machine can report transactions in real time to the central office. The Huawei MS2372 seems to replace the previous old model Huawei E220 modem, which was widely used in various terminals.

To support different LTE frequency bands from various network carriers, Huawei also presents many sub-models like the Huawei E3276 LTE Stick to support these networks:

 

Huawei MS2372h-517:

* LTE FDD B1/B2/B4/B5/B7/B12/B28

* UMTS B1/B2/B4/B5

* GSM：850/900/1800/1900

 

Huawei MS2372h-153:

* LTE FDD B1/B3/B7/B8/B20

* UMTS B1/B8. GSM 850/900/1800/1900

 

 

Huawei MS2372h-607:

* LTE FDD B1/B3/B7/B8/B19/B28 and LTE TDD B40

* UMTS B1/B6/B8/B19

* GSM 850/900/1800/1900

 

Extended temperature range

For the consumer market, usual LTE modems work only in a quite limited temperature range. For the MS2372, Huawei has significantly extended this temperature range, the stick works between -20 and +55 degrees Celsius. The Huawei 4G dongle requires a power supply of 5V / 700mA for operation and is quite compact at 88mm x 28mm x 11.5mm. The weight is just under 50 grams.

 

LTE Cat4 with 150 MBit/s

The maximum speed in the LTE network is around 150 MBit/s in the downlink and 50 MBit/s in the uplink. This corresponds to LTE category 4. In addition, the stick is backwards compatible with 3G/UMTS and 2G/GSM, including the data accelerators DC-HSPA+ and EDGE. The following frequency bands are supported by the model MS2372h-153 designed for the European market:

 

  • LTE: B1/B3/B7/ B8/B20
  • UMTS: B1 / B8
  • GSM: Quadband (50/900/1800/1900 MHz)

On the side of the USB stick, there are two connections for external antennas under one cover.

 

Control via AT commands

The Huawei MS2372 LTE stick can be controlled via AT commands, in addition to the 3GPP TS 27.007 and 27.005 standards, extended Huawei AT commands are also supported.

Availability

The Huawei MS2372 would be available soon around the beginning of 2018. We would take test for this new Huawei 4G dongle and show our report on www.4gltemall.com.

Difference between Samsung GT-B3740 and GT-B3730

Samsung is always leading the trend of networking development. As the partner model of Samsung GT-B3740, the 4G LTE Surfstick Samsung GT-B3730 is not as popular as GT-B3740. Samsung GT-B3730 4G Modem is the company’s first USB-based internet stick from TeliaSonera that offers 4G networks connectivity as well as a backup plan.

 

 

 

Samsung GT-B3740 could support maximum download speed up to 100Mbps download speed and 50mbps upload speed. Samsung GT-B3730 could also do that, the difference between them is Samsung GT-B3740 could work only on 4G LTE FDD 800MHz while Samsung GT-B3730 could only work on 4G LTE FDD 2600MHz. So Samsung GT-B3740 could only work specific areas in Europe, because not all the countries in Europe deployed the band 800MHz. And GT-B3730 is also the same; it has to work conditionally on only LTE FDD 2600MHz.

 

 

 

Samsung GT-B3730 seems more powerful in application because it could not only work with 4G network, it could also work on 3G UMTS 2100MHz and 2G GSM/GPRS/EDGE networks. So if there is unlocked Samsung GT-B3730, users could use in every countries in Europe. Under 3G network, Samsung GT-B3730 could support maximum download speed up to 17Mbps and upload speed up to 5.76Mbps.

 

 

Samsung GT-B3740 and GT-B3730 both have dual external antenna connector, with external antenna, users could get more stable network connection and better signal strength, but we didn’t get any official information for the connector type.

 

Samsung GT-B3740 is in compact USB design but GT-B3730 is in rotatable USB design. GT-B3740 is used for Vodafone 4G LTE networks in Germany, but GT-B3730 is for Sweden operator TeliaSonera. TeliaSonera has nationwide 4G licenses in Norway, Sweden, Finland and Denmark. So if you don’t have specific requirement, Samsung GT-3730 is good for personal use.

LTE Surf Sticks

LTE Sticks are technically radio modems, meaning little combined transmitting and receiving equipment, which operate on different frequencies.

 

They can be connected via the USB ports to virtually any device such as a larger netbook, laptop or home PC. The sticks are in demand, such as to use abroad, or a change to a new and faster wireless data technology, and they are easy to replace. In addition to the relatively small size and low weight, this versatility and the slight changes are the greatest advantage of the sticks.

 

Even with the older data radio technologies of UMTS and GSM, sticks still dominates the modem market, other solutions such as built-in modem or modem card format to be used much less frequently. For the majority of users, LTE Surfsticks will be the solution that makes mobile internet the fastest and easiest access.

 

The new LTE Sticks come from the Far East, currently dominate the South Korean manufacturer Samsung, LG Electronics and Pantech market, China’s Huawei tries to win over new entrants.

 

So the first LTE Stick was Samsung GT-B3740, which is developed by Samsung in Vodafone Brand. The next stick from Swedish-finished network operator Telia Sonera is the GT-B3710 from Samsung. Meanwhile, there is B3730, which dominated alongside LTE is UMTS and HSPA, GSM and EDGE, as well as wireless technologies. The device sends in LTE mode on the frequency 2600MHz. It is also used in the Vienna LTE network of the Austrian mobile operator A1 Telecom Austria. The B3740 is likely to be an optimized version with a similar standard.

 

The second LTE stick comes from Chinese mobile phone supplier, HUAWEI, it is HUAWEI E398. The device was tested in the LTE network of O2 and is now available at Telekom from the second half of 2011. In Austria, it is the mobile operator A1 Telekom Austria offered on its website.

 

 

Global Supply of LTE Sticks

 

There are very few data sticks, which are with wireless data LTE technology, so pure LTE Sticks have others technologies backward, such as UMTS, GSM and CDMA 2000 network to send and receive. Overall, a clear trend is emerging to stick with multi-technology, pure LTE Data sticks are shunned by the mobile operators.

 

 

The Pantech UML290, originates from South Korea, and sells for US Verizon Wireless LTE network. It’s like the stick used in Scandinavia and Austria from Samsung, sends an older and slower wireless technology on board. In the case it is spread in the U.S. CDMA 2000, and therefore he receives on 800 Mhz and 900 Mhz. For LTE reception, it is in the range of 700 MHz road.

 

The second stick, Verizon Wireless LG VL600 of the South Korean manufacturer LG Electronics. With LTE, it’s in the 700 MHz band travelling with the frequency used the U.S. 3G CDMA 2000 technology, it can send and receive on the 800MHz and 1900MHz band. LG Electronics also has the LD 100 model that is used in Japanese LTE network of Docomo. It also speaks several wireless data technologies, besides LTE, there is UMTS and HSPA, plug for the Japanese to travel abroad, GSM and GPRS are also included. GSM will be gradually switched off in Japanese networks.

 

What to look for LTE Sticks

 

All LTE Sticks on the market are significantly larger than the surf sticks with pure UMTS or GSM technologies; they therefore require more space on your laptop. If two or more USB ports close together, this may lead to another USB ports blocked. Therefore a rotatable mechanism for raising the stick is very useful to save some space with a bent 90 degrees stick, and most of these sticks have rotate mechanism.

 

Pure LTE Sticks can only be used where LTE is available. Since the LTE network is expanding coverage in many areas, it would take many years for LTE network to cover every corner. Therefore in some areas, you have to use other technologies UMTS and GSM, and the associated wireless data technologies HSPA and EDGE, to dominate the modem.

 

Several sticks offer external antenna connectors; one is for the older mobile technologies and one for LTE. This is an important consideration when buying, LTE will be predominantly at home or hospital use, we recommend you might install an LTE external antenna.
