LTE Dual-mode 4G Modem-ZTE MF880 VS MF825

More and more operators are investing the TD-LTE technology so as to improve the spectrum application efficiency. It seems the TDD technology would become the mainstream for LTE network. But We could also see the dual-mode LTE, that is FDD & TD-LTE combination, is also become popular.

 

 

To make the LTE dual-mode network more efficiency, the UEs must also support FDD and TDD bands simultaneously, and they could auto switch between the two modes. We have found there are many USB dongles, mobile WiFi hotspots and LTE router available for such networks.

 

 

As one of the important vendor for 4G LTE equipments, ZTE had released many models that can support TD-LTE/FDD dual-mode networks. ZTE MF880 and MF825 are such 4G USB dongles.

 

 

 

ZTE MF880 is the first generation 4G modem from ZTE. One of the main features for them is they don’t have the connector for MIMO external antennas. The body of the 4G modem is a little bit bigger than 3G modems. As a 4G dual-mode LTE modem, ZTE MF880 could support 4G FDD band 20 & band 7(800/2600MHz), and TD-LTE band 38 & band 40 (2300/2600MHz). Band 7 and band 20 are two most popular spectrums in European countries and the two TDD bands are the most commonly deployed broadband worldwide, which make ZTE MF880 4G data card one of the most popular 4G dongles.

 

 

ZTE MF825 is the typical model for the second generation of ZTE 4G modems. Based optimization and improve in hardware and firmware, the ZTE is much slimmer then it’s predecessors. And it’s not as big as ZTE MF880, and to make the MIMO transmission come true, two external antenna connectors are available in MF825. Besides the TDD band 38 & 40(2300/2600MHz), ZTE MF825 supports more FDD bands, they are band 20, band 3, band 1 & band 7(800/1800/2100/2600MHz). From the specification, we could know if ZTE MF880 could work in any place, ZTE MF825 would fully replace it.

 

 

 

What’s more, the two 4G dongles ZTE MF880 and MF825 could also work on 3G UMTS/DC-HSPA+ networks (900/2100MHz) and 2G GAM/GPRS networks, and the peak download speed on 3G could reach 42Mbps. So if user is in a location where 4G network is not available, the two ZTE 4G modems would switch to 3G to fulfill the Internet access requirement.

 

 

Someone may ask, if ZTE MF825 could fully replace MF880, then why they both are presented from operators? It’s a good question, actually, the more powerful one device is, and the more expensive it is. ZTE MF825 is more powerful based on its great internal chipset, and it costs more. For some operators, it’s unnecessary for them to use a modem with high price when a cheaper one could meet the requirements. And for some operators, they didn’t provide some of the network spectrums that ZTE MF825 supports.

 

But for users who usually travel overseas or to different countries, it would be better to get ZTE MF825, because it would be more possible for the data card to compatible with the target operators when on a trip.

 

To conclude, the LTE dual-mode 4G modems provide better solution for users to access Internet and travel around. If you want more TD-LTE/FDD USB modem, welcome to visit www.4gltemall.com .

 

ZTE MF28G 4G LTE Router VS ZTE MF28D 4G LTE CPE

As the one of the most important UE device to support 4G LTE networks, 4G Router is on a replaceable position. Many vendors are trying their best to improve the research and development on this field. The Chinese vendor ZTE is also trying to present more telecommunication equipments to share the market.

 

As we can see, just ZTE 4G Modems, ZTE 4G Routers also looks very similar in appearance. Perhaps they just want to save more budgets, just using one appearance design and change the inner core part to make up a new model. So users usually can’t identify which model number of a LTE router, even when they know two model numbers of the router, they don’t know what the difference between them is. ZTE MF28G and MF28D are just on the case.

 

ZTE MF28G and MF28D are the 4G LTE CPE/Router from ZTE, they are for the 4G LTE networks and provide high speed Internet connection.

 

 

Appearance

 

As we said, they are using same appearance design, from the outside, we can’t tell from them. There are almost same indicators on the front screen, on the back, there are 4 RJ45 Ethernet cable ports, 2 RJ11 connector for analog telephone and one USB 2.0 interface for host file sharing.  And beside is the plug port for power supply.

 

 

Network Frequency Bands

 

 

The frequency bands supported should be the key difference between the two 4G Routers. ZTE MF28D router is a FDD-LTE router, which support 4G FDD band 1, band 3, band 7 and band 20 (800/1800/2100/2600MHz). And 3G DC-HSPA+/UMTS networks (900/1200MHz) are backward compatible.

 

 

ZTE MF28G LTE CPE is a FDD/TD-LTE dual-mode CPE router. MF28G Router could support FDD band 7 band 20(800/2600MHz), and TD-LTE band 38 & band 40 (2300/2600MHz). Similarly, ZTE MF28G LTE router also could support 3G networks as backup.

 

 

Connection Speed and User Support

 

In good network environment, the peak download speed of ZTE MF28D could reach 100Mbps and upload speed to 50Mbps when work on FDD networks. The speed ZTE MF28G varies depending on the network mode. When working on TDD mode, MF28G could allow maximum download speed up to 68Mbps and upload speed up to 17Mbps. However, if working on FDD LTE networks, the downlink could reach 100Mbps and uplink could reach 50Mbps.

 

 

Of course, the speeds above for data rate speed are theoretical and can make true only in preface situation. In real life, the speeds may not as faster as expected, but it’s still amazing and much faster than 3G speed.

 

ZTE MF28G and MF28D could both allow up to 32 users to get connected and surf. So they are good for SOHO, home and small office. The USB interface is help group users to share the files via host Memory.

ZTE MF28B Rogers LTE Rocket Hub VS ZTE MF28G 4G LTE Router

As one of the main 4G LTE telecommunication equipment vendor, ZTE has presented many 4G LTE router to public, and most of them are already for operators’ contract plan. Unlike Huawei B593 4G LTE CPE many modification models, each of ZTE 4G LTE routers has specific modem name, even though they look almost same in appearance.

 

 

 

ZTE 4G LTE routers are designed in same appearance model, but they are not completely the same in some aspects.  Today, we will have a review of the difference between ZTE MF28B and MF28G 4G LTE Router.

 

 

Network Bands

 

Most of the routers with appearance differ on the network bands. They are for different operators. ZTE MF28B Router is for Canadian operator Rogers, and it’s also called Rogers LTE Rocket Hub, but MF28B Hub could support single LTE band 7 (2600MHz), 3G HSPA (850/1900MHz) network is backward. As we can, it mainly for 3G network in North America.

 

 

ZTE MF28G LTE Router is more powerful, it supports LTE dual-mode (TDD & FDD), it could support 4G TDD band 38 & band 40 (2300/2600MHz) and FDD band 7 & band 20 (800/2600). And ZTE MF28G supports 3G UMTS 900/2100MHz. ZTE MF880 4G LTE USB dongle could support these bands.

 

So unlocked ZTE MF28G could work with more 4G operators and in some countries, MF28G could replace MF28B.

 

 

Data Rate Speed

 

 

ZTE MF28B and MF28G could both reach peak downlink speed up to 100Mbps and uplink speed to 50Mbps on 4G FDD network. Simultaneously, MF28G could reach peak downlink up to 68Mbps and uplink speed to 17Mbps when working on TDD networks.

 

 

Interfaces

 

 

There are some adjustments in the bodies of the two ZTE LTE routers. MF28B has only 4 Ethernet ports (RJ45) while MF28G has 4 Ethernet. Ports, 2 RJ11 ports for telephone, and one USB 2.0 host port. So MF28G could support telephone and SD files sharing, but MF28B cannot.

 

 

Logo

 

 

Sometimes, the logo on the router may vary according to operators. And the firmware may also be customized for operators. As we can see, the Rogers LTE Hub ZTE MF28B has Rogers’s logo on it and the forms are version is also with Rogers logo.

 

 

 

Other features of the routers are almost the same, to conclude, Unlocked ZTE MF28G is powerful when roaming globally. In certain countries, MF28B may be reliable on 3G networks.

ZTE MF91D 4G LTE Pocket WiFi Hotspot Review

Smartphones are the ideal way to access the Internet on the go, but when you want to connect more WiFi device and help a friend to access internet, things seems bad. In these cases we have to use a mobile hotspot, which provides quick access to the Internet for more than one device at a time. This time I am getting to know more detail of ZTE MF91D 4G LTE Mobile Hotspot that could connects to the Internet via a super fast LTE/4G network.

 

Last time we introduced the 3G HSDPA access point ZTE MF80, which is quite similar to the new version. Of course, the main difference is that the model MF91D hotspot is for LTE/4G network.

 

Appearance of ZTE MF91D

At first glance, ZTE MF91D Hotspot reminded me those nice rounded tip cell phones, which were quite common and popular one. The 4G hotspot is pleasant, easy to stow in the pocket. The front side has a simple square color display that shows the status of network connection. Below the screen is a big button, when working, it flashes of blue light. On the left side we find a slot for microSD memory card  at the side the MicroUSB connector for charging. On the other hand, there are two connectors for external antenna and in the middle of them, there is a WPS button. ZTE MF91D is made of plastic, when first use, remove the back cover and the battery, below is the slot to insert the SIM card of normal size.

 

ZTE MF91d Settings

To access and use the access point ZTE MF91D, computer could get connected through the USB cable or do a wireless all together. In the first application, the easiest way is by using the cable, especially if you’ve got a new SIM card that is locked with a PIN code. When connecting to a computer, your MF91D hotspot offer installation of software that simplifies the process of setting and place a shortcut to the settings page (we checked it also works on Mac OS X). Usually, the MF91D hotspot could auto configure and get connected after SIM card is plugged in.

 

Once you have your device connected to the access point, either via cable or via WiFi, you could open a web browser by typing the title http://m.home/ or http://192.168.1.1 (the default password admin ). On the home page, you have an overview of the various settings links and an overview of the data usage. If you do not have special requirements, you can leave most of the settings alone, but usually you need to change your password to something that you will easily remember.

 

Advanced users could setup detailed security and configure network settings. In general Wi-Fi settings, you can define the maximum number of connected devices. Hotspot ZTE MF91D supports up to 10 devices simultaneously.

ZTE MF91D Hotspot in practice

In the past few days, I’ve tested ZTE MF91D access point in different situations. I tested it in the open air, in a meeting with two laptops and smart phones, when at home, up to six devices get connection at the same time and each time the Internet works fast without interruption.

 

 

Speed is of course just like cellular phones, it depends on how far you are from the base station. The occupancy of cells can affect the signal quality. The battery should support 6 hours of continuous use, which was confirmed by my tests.

 

 

Who is it for?

If you use the mobile internet mostly with your smartphone, you probably do not need mobile access point. If you often find yourself on the road even with a laptop or tablet without a SIM card, the ZTE MF91D 4G hotspot is more attractive choice because it has a relatively long life battery, and it is extremely easy to use. It can be used even in small office or home to connect multiple users at the same time, it supports up to as many as 10 devices at a time. What is most attractive, ZTE MF91D could support maximum download speed up to 100Mbps, so any connected users could surf internet in very high speed.

 

 

Of course, there is not only ZTE MF91D 4G LTE Mobile Hotspot, many other brand 4G Mobile Routers are available, welcome to check more on 4gltemall.com .

ZTE MF91 4G LTE Pocket WiFi Hotspot Test Report

The company ZTE from China has extensive experience in the manufacturing mobile phones; this fact has a positive impact on the shape and ergonomics of the mini router. Since the mobile device and should always be at hand, the shape and size of a mini router should allow to carry in any pocket or bag. Here we get the 4G LTE Mini Router ZTE MF91 Pocket WiFi Router. Let us have a look at this smart 4G LTE Router and how it works.

 

 

When we open the box, we can find these content are included in the package: ZTE MF91, power charger and USB Cable. The router is a standard rectangular box with rounded corners. On the front is a small screen and a single button switch. The user manual is also included.

 

 

To prepare the router to work, you must first insert a SIM-card. Open the back cover, take out the battery. Here we see at once the place for SIM-card, at which point you have to be careful. And put the card in a special tray to move it forward.

 

After the SIM card in the slot, put the battery in. Before you close the back cover of the machine, you must remember to write down the password for the Wi-Fi connection, it is printed on the back cover. Then just press the round button, wait a few seconds and the device is ready for use. This is what we signals appeared on the screen legend – ALTEL 4G.

 

 

Just want to say a few words on the screen, despite its small size (1.44 inches), it is quite informative in addition to network status and signal strength (by the way it’s showing with a symbol and the number of sticks like a conventional phone), the screen displays the status of Wi-Fi, the number of connected devices, and battery level.

 

In the center of the screen, we see the total time of using 4G data, as well as the total amount of data received/transmitted during this session. The device screen is quite bright, the information could be read, even in direct sunlight.

 

 

After switching on the router you just need to enter the password and connect it via Wi-Fi from your tablet, Smartphone or laptop. The manufacturer claims the simultaneous connection of 10 different WiFi devices.

 

The router is equipped with a powerful battery capacity of 2300 mAh, it is quite enough for me on day of use without switching off, and the network I was using for three hours, the rest of the time in standby mode. A full battery charge is approximately 2.5 hours.

 

 

The stated range of the router Wi-Fi signal could be distributed to 10-15 meters, my experience of operating in principle confirms these figures, and in a normal urban 2-room apartment, signal was available at any point. On the street, the range is from 8 m to 16 m, depending on the availability of natural environment.

 

In my opinion, the ZTE MF91 4G LTE Mobile router is very practical and convenient solution for wireless Internet in the format of 4G. Ergonomic shape, small size and relatively low weight (110 g) fully permit to carry with users. It could be easily fit into any pocket, bag or purse. If you want unlocked without any contract, welcome to buy from www.4gltemall.com .

Huawei E398S-81 4G LTE FDD TDD USB Surfstick Review

Comparing with Huawei E398 other branch models, such as Huawei E398u-1, E398u-18 and E398u-15, Huawei E398s-81 should be a special one, it’s not because Huawei E398s-81 has different appearance as other models, it’s due to Huawei E398s-81 supports the TDD & FDD LTE band simultaneously, which covers the 4G LTE TDD 2300/2600MHz and FDD 2600MHz.

 

 

As the one of the most frequency bands for TDD, band 38 (2600MHz) and band 40 (2300Mhz) are invested by many operators who are planning or already launched TDD networks.

 

 

Today, we get the Huawei E398s-81 4G LTE TDD FDD Surf stick with HUAWEI logo on it. It seems that it’s SIM card free and unlocked to any operators. Usually, if there is an operator’s logo on HUAWEI E398 modem, it may be a locked one, but the modem could be unlocked by some methods.

 

From the appearance, we could see that HUAWEI E398s-81 is just like other E398 branch models, with the rotatable USB design. There is only HUAWEI 4G on the USB. No other logo was printed on the back.

 

 

As previously mentioned, Huawei E398s-81 could support the LTE bands/Spectrum above: 4G LTE FDD 2600MHz and TDD 2300/2600MHz. This should be the most important difference between HUAWEI E398u-1, E398u-15 and E398u-18.

 

 

With same appearance of E398u-11 and E398u-15, Huawei E398s-81 has two external antenna connectors beside the two sides of Micro SD slot. If user wants to use data card with MIMO technology, HUAWEI E398s-81 is a good option optional. Here now, only few models of 4G LTE USB Surfstick are available on the market for both TDD and FDD networks. HUAWEI E398s-81 should be a good one based on HUAWEI prestige.

 

 

Unlike other E398 Modems, Huawei E398s-81 could not work with 3G UMTS network or 2G GSM/GPRS network. So Huawei E398S-81 could only work on 4G LTE networks. If 4G networks are not available in certain place, HUAWEI E398s-81 can’t work. So users may consider this before they buy it.

 

 

 

As the brother model, Huawei E392 4G FDD TDD multi-mode data card also has one similar model, the model number is Huawei E392u-92. HUAWEI E392u-92 supports 4G TDD 2300/2600 Mhz, but HUAWEI E392u-92 can’t support 4G FDD networks.
