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.

4G LTE Router

An LTE Router is technically a wireless modem, so a small transmitting and receiving station, which is designed for the LTE wireless data technology.

Unlike the USB Stick, which can only have one device connected to the high speed data radio network, the router uses several computers simultaneously. LTE Router is in two versions, most of them use it as a stationary device, which allows you to build a home or office WiFi network, there are also mobile devices that provides the same services when travelling.

In some places over the world, the LTE network is first built in areas where there is no high speed internet at speeds exceeding one megabit per second. LTE is thus used only once as a steady replacement for fast internet access and in the second step as fast mobile technology. Therefore LTE router was firstly users as LTE modems as typical stationary applications.

LTE Router Telekom – Germany Forward World

It is therefore not too surprising that Telekom was able to present their LTE Router to public as the world’s first mobile operator. At theoretical maximum speeds creates the telecom router 50 megabits per second, when download data at 10mbps when sending (uploading). The PC or laptop to wireless via WLAN (standard 802.11b/g) or wired (standard: IEEE 802.3/802.3u) can be connected. The router is sold by Telecom under the name Speedport LTE, there are for the LTE Speedport B390 from the Chinese manufacturer HUAWEI.

At the Munich mobile operator Telefonica(O2), however, is a unit of Germany production in the sample phase, a Fritz Box by AVM Berlin. The LTE modem with a theoretical top speed of 100megabits per second and receive data at up to 50Mbit/s transmit data. LTE fritz box transmits in two frequency bands: 800Mhz and 2600MHz band. So the frequencies are provided in Germany to LTE.

 

Routers work their way up

Except for the special case of Germany, LTE is built around the world from the beginning as a fast mobile Internet access. Therefore, mobile radio modems as the stick in the other countries are the first choice. Routers, which are mostly used in a stationary come, much later on the market.

 

What should be considered when buying LTE ROUTERS?

A router is used for multiple computers at the same time to be given an access to the internet. Regarding the wireless data rate, the more subscribers logged, i.e. a transmission tower and the more participants at a base station, the slower the data transmission. These fluctuating velocity, which never reached the heights that are announced in the mobile advertising, the user of a router must then share with each other again. The more devices via the router is active, the slower the speed of each computer.

Those who want to obtain high speeds with LTE will take a USB Stick per unit, and then of course, a monthly fee occurs per device. Who wants to pay for the whole family or shared only a monthly subscription, can take a router, then of course move slowly, if at the same time invite the children on their computer music from the net.

A second criterion for the selection of the router is the question of whether it will be used stationary or mobile. If it is used stationary, it is enough perhaps, if he is only capable of wireless data LTE technology. But when on the move, it should absolutely dominate the other popular wireless technologies in Germany, data from the GSM network and UMTS network, IE GPRS, EDGE and HSPA on board.

If the LTE connection be reasonably equivalent DSL replacement, your router can be used as a telephone at the same time.

 

It would be useful for a router also with an external antenna connector, which can be used in peripheral locations of masts improve the weak radio signal. This then ensures a faster transfer. Such antennas are in the consumer Internet, sometimes in the shop of the LTE party.

 

LTE Netbooks Guides

An LTE netbook is a small, portable computer with a built-in wireless modem that can send and receive with the LTE technology.

Networks usually have a screen with a screen size less than twelve inches, and the keyboard is much smaller. They are designed as a device with which it mainly goes mobile to the Internet. For other functions, such as writing or creating graphics are much less suitable.

Currently there are three LTE netbooks, which have already been presented to the public. All three are not on the market. The first netbook has been released for the LTE network of U.S. LTE operator Verizon Wireless.

 

The LTE Modems

The built-in LTE Modem into the netbook is a small wireless transmitter that is located inside the computer, and not visible from the outside. While sticks, routers an modems are connected in card form from the outside through a slot to the device, they are hidden under the hood here. The advantage of slots, such as the USB ports free for the other functions such as USB memory sticks.

These LTE modems to be installed in portable computers offer the chipmaker to already. They will be installed by netbook manufacturers buy only in more devices, if a sufficiently large market for such LTE netbooks has formed. First choice as a modem first LTE surf sticks will be, with which existing mobile computers for the new wireless data technology to be retrofitted.

 

Three Netbooks in the race

 

There are currently three LTE netbooks, which were presented to the publice. All three have been upgraded on the basis of existing models with an LTE radio modem. It is already clear that this will be the path of development, based on the most mobile LTE computer company, a successful model is upgraded with the new technology and is possibly still in the area for camera or hard disk.

South Korea’s Samsung showed the first LTE netbook at the beginning of 2010, the Samsung N150 LTE. It has been long on the market and according to experts, it’s a netbook with many others features such as LTE-enabled version with built-in wireless modem.

The first LTE netbook you will probably be able to buy is in the USA, since the Apple New iPad released, many PC manufacturers follow the trend, but there are many factors under worry. First, the 4G LTE band compatibility is big problem, because in different areas, the deployed 4G LTE spectrums are completely different, so there will be many brand models for even a single netbook. If one manufacturer want to produce on model to compatible with all the 4g LTE networks, it’s obvious unpractical. With higher price, the customer may not give a shit. Second, the power supply is a big headache in 3G netbook. The operation system Android and IOS both consumes power in large volumes; the battery with the device is not enough. When running on 4G, netbooks need more power, then it’s also a problem for manufacturers.

But with mobile power bank, the netbook could find a acceptable solution for power. HUAWEI E5756 is a device with power bank and WiFi router functions 2 in 1. It’s a good solution during this time, but it support HSPA+ 42Mbps download speed ,which seems for 3G Advanced network, not 4G.

 

Advisor: LTE Laptop Datacards

An LTE Laptop card is a radio modem, which is a small transmitter and receiver station which dominates the radio data technology of LTE. It is connected via a card slot on a laptop.

 

Wireless modem cards are more and more of a niche product, but most users prefer the much more portable USB flash drive. However, these sticks are in LTE design advised comparatively clunky, since you do need space to the necessary for LTE dual-antenna accommodate. It remains to be seen whether this will lead to a return of the wireless data cards.

 

This is theoretical consideration for the time being, as at present, Fujitsu is the world’s only LTE-compatible card on the market. It’s offered by Japanese mobile operator DoCoMo on its network: The F-06C from the Japanese manufacturer Fujitsu.

 

The radio modem in map form in LTE networks can receive a maximum of 75 megabits per second data (downlink) and 25 Mbps receive(uplink). In the UMTS network of the third generation, it offers a theoretical maximum 7.2Mbit/s when downloading the data transmission technology HSDPA and 5.7Mbit/s upload speeds with HSUPA.

 

What you should consider when buying

 

A data card is, given the very large size of the LTE Surf sticks, possibly a real alternative. This is especially true if the USB ports of your laptop or notebook computers are so close together that by LTE surf stick possibly two slots are blocked. In such cased, a wireless modem in card fromat can be a useful variant.

 

LTE Antennas—You will always need double

Those who wants to surf with LTE really fast, which can improve the reception of the radio signal by additional antenna.

 

But beware: while the UMTS radio technology usually received via an antenna, LTE always uses the multi-antenna technology. It’s on two antennas to send and receive data. So you have to always connect two antennas to be receiver. Suitable antennas are double it commercially as a total package; they sometimes look like a tool. If in doubt, ask if there is a dual antenna.

 

Before you buy the antenna that your receiver is ready for connection to a pair of antennas. Receivers are modems such as routers, surf stick modems in card form or radio modems that are built already in tablet, notebook or netbook. If you do not know it yourself, ask the dealer or the seller, whether your device has such a connection for a dual antenna.

 

 

Types of Antennas and antenna purchase

 

There are two types of antenna for LTE: The Omni-directional antennas can be placed up and receive the signal from any direction. However, there are also good and bad places for the erection of the antenna.

 

The directional antennas generally provide a much better result; they have to be aligned with the respective LTE mast. You should know, however, where are the nearest towers. This information provides the agency on a separate card. Simply enter the city, and then you will be presented in a easy map to set of transmission towers around your home or office.

 

The seller of LTE antennas often offer a complete package in which is already containing everything they need. The antenna pair, the associated connection cables, often even a holder for parallel installation of two antennas. Suitable antenna packages are also on LTE mobile operators sometimes offers, in addition to the receiving equipment such as a modem or router.

 

Our tips for easy installation

 

During the assembly, proceed as follows: first, find the right location, either inside the home or outside. You connect the antenna to your computer, and check the signal strength at various locations. You can see the signal strength on the modem. Some vendors offer LTE signal strength measurements via Internet. If you want to do the test, you have to measure computer and a speedometer, the transmission speed at different locations.

 

Where the reception is strongest, you should place the antenna. When you place the antenna inside your own house, then close to or directly on the window, from which you get the best reception. In this case, make sure the antenna distance from the modem or other electronic devices, such as television, radio, PC, electric fields interfere with the signal.

 

The second way to set up the antenna outside of the home, is therefore at the top of the attice, on the roof or on an outside wall. Whichever course choose, you should keep at least one meter away from poles, pipes or railings. Under no circumstances should you screw the antenna on a metal plate or wall. If you need to put the antenna on a mast, then you must sit above the top of the mast, where possible, over the roof edge. The principle is around the antenna, there will be no metal—metal shields radio signals.

 

When you buy yourself a pair of directional antennas, in addition to make two points: First, then antennas are mounted at the same height, and secondly, they are aligned parallel to each standing, to the nearest mast. It’s best to consult it in stores.
