ZTE MF822 4G Aircard VS ZTE MF823 4G Modem

Since more and more people are using 4G network for their home or office, they improve the communication efficiency through high network connection speed. As one of the important telecom equipment sipplier, ZTE had releases many 4G Aircards for various operators. And more and more people know ZTE and ZTE 4G modems.



ZTE MF823 and MF822 are two of the hot 4G dongles. ZTE MF823 is the world’s slimmest 4G USB dongle. Due to the compacity requirement, the inner part of a 4G modem usually contains more contents so as to fulfill more functions and high demand for network. This feature makes 4G dongle in bigger body than 3G modems. ZTE optimized this feature and let MF823 in slim size, actually, some predecessor model of ZTE MF823 is also very big, many users feedback they don’t like the big body..


ZTEMF823 4G USB Stick is now available for O2 contract, the O2 LTE USB 4G could support 4G LTE FDD bands 3/7/8/20 (800/900/1800/2600MHz), which is for Germany 4G network. However, the unlocked ZTE MF823 would in other European countries, such France, Portugal, UK, Switzerland, Netherlands and Finland. Most of the 4G network frequency bands are similar, which makes the roam of ZTE MF823 come true. What’s more, ZTE Mf823 could work with most 4G operators in Asia and Middle East.



By the way, unlike the first generation 4G dongle from ZTE, MF823 is in compact USB design, the USB can’t rotate. The other model ZTE MF822 is one special one, it’s a 4G USB Modem for North America. It could support 4G LTE frequency band 4 and band 7 (1700/2100/2600MHz), which is mostly deployed in Canada and USA. ZTE MF822 is already available for Canada operator “Rogers”. To work with Rogers, the FCC certificate is necessary for the device. As we know, ZTE MF822 is the only model that combines 4G band 4 and band 7. So unlocked ZTE MF822 could work in Canada and also roam to work with some operators in USA. Frankly speaking, ZTE MF822 could also work with the operators in Asia and Europe who provider the LTE band 7. So MF822 is also powerful in the compatibility with global operators.



ZTE MF823 and MF822 are not brother models, but they are both LTE category 3 USB modem. They both support the peak download speed up to 100Mbps and upload speed up to 50Mbps. The speeds are amazing for the user to trip or surf outdoor, if you want unlock MF823 or MF822, welcome to visit http://www.4gltemall.com/4g-usb-modem/zte-4g-lte-modem.html .




Most of ZTE 4G modems looks the same, and the first generation of ZTE 4G Dongles are all using same appearance design, so it becomes much harder to identify them. No wonder what the difference between them is. We open the blog especially for clear out the similar 4G devices and let users know more about the details of the LTE modems they had used.



ZTE MF820T and ZTE MF820D are two similar 4G LTE sticks for first generation ZTE 4G USB modems. Most of the modems, appearance similar or not, their difference are mainly on the core part, that is the platform chipset, which decides what LTE frequency bands that could support and where they can be used.


ZTE MF820T is based on Qualcomm MDM9600 chipset, it could work TD-LTE bands 38 and band 40 (2300/2600MHz). ZTE MF820D is based on Qualcomm MDM9200 chipset, it would support FDD LTE band 3, 7 and 20 (800/1800/2600MHz). Unlike ZTE MF880, they can only work on single TD-LTE network or FDD network, MF880 would support LTE dual-mode (TDD&FDD).



As the typical features of ZTE first generation 4G USB stick, there is no external antenna connector in the dongle, so the LTE MIMO transmission can’t make true. But there is built-in antenna which is still reliable to connect network in high speed.


What’s more, there is no MicroSD card slot available in MF820T and MF820D. We suppose they are not for single user, it’s more like designed for large data in project test or other research terms. However, the 4G aircard may be more reliable when there is no SD card sharing function. According to the experience in 3G modems, SD card usually causes the application of wireless dongle in trouble.



And we can see the big body of the 4G modem ZTE MF820D and MF820T is not user-friendly. It’s almost twice bigger than ZTE 3G modems. We hope there will be some smarter or slimmer models available in near future, and this will not only need the improvement in the design for inner part, but also the function more powerful.


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 .


Difference Between ZTE MF910 and ZTE MF91D 4G LTE Router

Just like ZTE 4G LTE USB modems, ZTE 4G LTE mobile Hotspot looks the same in appearance, but there are some difference between these models. ZTE MF910 and MF91D are two 4G mobile pocket router that looks the same.




Today, we will have a Review of the two similar 4G Pocket WiFi Router. As we know, the ZTE MF91D 4G hotspot has already been presented to public for operators in many countries. It seems ZTE MF910 WiFi hotspot seems not as popular as MF91D right now. But after we review the two MIFIs, you may change this idea.



As we can see, the two mobile hotspots look very similar, we suppose the manufacturer ZTE use the same design appearance for MF910 and MF91D. There is only one button on the front of device, below the screen. There are WPS button, MicroSD card slot and external antenna connector at the side of the body. And one more USB interface for battery charge.


The SIM card slot is in the inner part of the body, user must open the back cover and remove the battery to insert SIM card.





UE category and Link Speed



ZTE MF910 and MF91D are both LTE category 3 mobile router, as the typical feature of Cat 3, the mobile 4G router could support maximum download speed up to 100Mbps, and the peak download speed could reach 50Mbps.


What’s more, the 3G UMTS and 2G GSM/GPRS networks are backward. When working on 3G DC-HSPA+ network, the peak speed could reach 42Mbps. So when user goes to somewhere 4G network is not available, the 4G MiFi could auto switch and work on 3G network in high speed.



Networks Bands


This should be the core difference between MF910 an MF91D. Because this decides where they could work and which operator they would support. The ZTE MF91D could support 4G LTE Band 8, Band 3 and Band 7 (900/1800/2600MHz) while ZTE MF91D would support the three bands and Band 20(800MHz). With this specification, they both could roam in most European countries. But in some specific areas, ZTE MF91D may be unable to work on 4g Network. For example, if user uses the MF91D in remote area far from downtown where the 4G band 20 is deployed, it may not connect to 4G and switch to 3G network.



It may not occur on ZTE MF910 because it supports the most popular three LTE bands in Europe areas. So unlock ZTE MF910 could fully replace MF91D. Someone may ask, then why the two models exist simultaneously? It’s a good question, usually, the more bands a UE decide could support, the more expensive it is. So ZTE MF91D is in lower price than MF910. And some operator didn’t adopt the LTE band 20, it’s unnecessary for them to order a device with this band supported.



By the way, almost all the LTE mobile WiFi Hotspot could support up to 10 WiFi users to access Internet and surf, including the ZTE MF910 and MF91D.




In conclusion, ZTE MF910 4G hotspot is more powerful than MF91D, but user could buy budget MF91D per the actual situation. If you want know more 4G mobile hotspots, welcome to land www.4gltemall.com .





ZTE MF823 4G LTE Datacard- World’s Smallest 4G USB Surfstick

ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly traded, global provider of telecommunications equipment, network solutions and mobile devices, announced the market launch of the ZTE MF823 known, the smallest 4G LTE data card in the world.

With its driver-less functionality ZTE MF823 4G LTE Datacard offers consumers a quick and easy internet access. It uses Qualcomm’s LTE chip platform of the second generation and has a thickness of only 13mm, which is nearly a third of the size of LTE data cards and the first generation makes it the smallest LTE map of the world.


The MF823 works with Web UI, supports IPv6 and is compatible with all major operating systems and Win8/XP/Mac. Since they LTE FDD DL / UL 100/50Mbps and UMTS HSPA +: support DL / UL 42/5.76Mbps and backward compatible with GPRS / GSM, it offers users wherever they are, high-speed access to the Internet without landline or public hotspot.

Moreover, it is succeeded ZTE, reduce the power consumption in comparison with the MF823 LTE cards of the first generation by a third. Their emission properties were improved and because it has the industry’s lowest operating temperature, it heats itself not on prolonged use.


The MF823 has been in terms of high bandwidth, low latency and high communication rates optimized (the failure rate of the data and to reduce voice transmission), so that users can enjoy a new generation of mobile internet access with high bandwidth.


The ZTE MF823 is already available in Kazakhstan and will soon arrive in Europe and Asia-Pacific countries to the market.


Since 2008, ZTE has focused its research and development and investments on its LTE products and received several core technology patents for LTE devices. This year brought the ZTE MF820S2 the world’s first multi-standard USB modem and to the MF91S the first UFI device in the world to market. In addition, ZTE was the first Chinese manufacturer to introduce a 4G LTE smartphone, the Grand X LTE (T82). Among global telecom vendors ZTE currently has seven per cent of the basic patents for 4G LTE.
