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 Routersare available, welcome to check more on 4gltemall.com .

TDD Band 40 (2300MHz) and LTE UEs for Band 40

The 2300MHz band has already been defined as a 3GPP eUTRAN band (band 40) based on a Time Division Duplex (TDD) scheme. First significant rollouts have already started in India (Bharti Airtel operator) and in Saudi Arabia (STC operator), with several others following by 2013.    

 

According to the Global Suppliers Association (GSA), 43 commercial devices supporting the 2300MHz band are now available on the market, including multi-band and multi-frequency Customer Premises Equipment (CPE), dongles and portable hotspots, while tablets and smartphones will be commercially available by the end of 2012. Even the early European adopters will be able to rely on the economies of scale that are now being established in other regions thanks to the global identification of the 2300MHz band by the International Telecommunication Union (ITU-R) for the IMT family of technologies.    

 

 

LTE-TDD is now gaining market traction in all regions as it is commonly considered in the evolution path of any wireless cellular TDD technology (TD-SCDMA, UTRA-TDD and WiMAX™). LTE-TDD is an integral part of the 3GPP standards, sharing significant common properties with LTE-FDD and offering comparable performance characteristics with similar high-spectral efficiency. Globally, 80 LTE networks were launched in 38 countries between December 2009 and June 2012. LTE-TDD is now entering maturity stage: 33 trial and 23 commercial LTE-TDD networks launched in Brazil, India, Japan, Poland, the Russian Federation and Saudi Arabia by April 2012; and several new rollouts will take place in 2012 also involving the USA and all the BRIC countries (Brazil, Russia, India and China). All major network equipment manufacturers stressed the importance of LTE-TDD and have already launched their LTE-TDD solutions. LTE-TDD will reach economies of scale comparable with LTE-FDD in the longer term. With its large spectrum availability (up to 100MHz in the lowest available TDD band in Europe), the 2300MHz band will play a major role within the European ‘TDD bands’ in the short term.     Growing support from global industry for the 2300MHz band is increasingly evident; in March DIGITALEUROPE clearly stated its position in favour of rapid availability of 2300MHz harmonised spectrum across Europe. From an early stage, the European 2300MHz market will be able to leverage economies of scale from global TDD consolidation, enabled by the ITU-R global allocation, and by the growing availability of spectrum, as well as the arrival of suitable end-user devices.    

 

 

The following diagram provides information on allocations and assignments among key 2300MHz markets: band 40 2300mhz spectrum assignments          

 

Australia:

 

In order to gain access to the 2300MHz spectrum, Australian operator Optus is soon expected to complete its acquisition of another Australian operator, Vividwireless. Once confirmed by local regulatory authorities, Optus will be able to rely on almost all the 98MHz portion of spectrum in the Australian 2300MHz band.  

 

China:

The 2300MHz band is allocated to the Ministry of Information Technology (IMT) in China. China Mobile owns 50MHz in the 2300MHz band which can be used for indoor services at this time (the band is currently used by radiolocation services). China Mobile, having identified LTE-TDD technology as the long-term evolution of TD-SCDMA, is expected to increase investments in the near future. Additionally China Mobile is currently undertaking a large-scale LTE-TDD trial involving the 1900MHz, the 2300MHz and the 2600MHz TDD bands. Some 1000 eNBs have been rolled out in six cities in the first phase (Proof of Concept, completed in September 2011), 20,000 base stations and multimode user equipment tests are being performed in the second phase (R&D technical experiment and scaled trial) which will expand to nine cities and will end by December 2012. China Mobile plans to gradually upgrade 200,000 TD-SCDMA base stations to LTE-TDD by 2013.  

 

India:

In June 2010, each of six operators acquired one 20MHz license, with different geographic extensions, at a total cost of $US5.2 billion. Reliance Industries is the only operator with pan-Indian coverage while Bharti Airtel was the first operator to launch LTETDD commercial services in India in April 2012, starting with Mumbai, Delhi, Kolkata and Bangalore. Bharti Airtel has recently signed an agreement for the acquisition of Qualcomm AP’s BWA spectrum by 2014.  

 

Saudi Arabia:

STC commercially launched its LTE-TDD service in September 2011. This is the biggest LTE-TDD 2300MHz network in the Middle East. By May 2012, STC had already upgraded 1500 base stations serving 38 cities and is targeting 65% population coverage by end-2012. In parallel, competitor Mobily has also launched its 2600MHz LTE-TDD network.

 

Denmark:

In May 2011, a public consultation document entitled “A strategy to find an extra 600MHz for broadband” by the Danish regulator NTIA proposed the availability of the 2300MHz spectrum band by 2015.  

 

Ireland:

 

 

In October 2009 ComReg carried out a public consultation on “Release of Spectrum in the 2300-2400MHz band”. In its April 2011 consultation, “Review of the Period 2008 – 2010 & Proposed Strategy for Managing the Radio Spectrum: 2011 – 2013’ ComReg recognised the “great potential [of the 2300MHz band] to enhance competition and capacity for mobile broadband within Ireland”, once the ECC harmonisation work has been completed. According to the recently closed public consultation on its “Draft Strategy Statement 2012 – 2014“, ComReg will develop a new consultation “on a future release of the 2.3GHz band” which will also include economic analysis of the type of competitive award, fees and license conditions.  

 

Sweden:

PTS, the Swedish regulator, is considering the 2300MHz band in its roadmap for the release of more than 500MHz “new” spectrum in Sweden. PTS has been planning to release 2300MHz band for some time. Depending on market demand, spectrum could be auctioned starting from 2013. A first public consultation “regarding planned radio use in the 2.3GHz band” was held in November 2010. A more recent consultation addressing technical issues related to the 2300MHz band (e.g. coexistence matters, band plan, etc.) was closed in February 2012.  

 

 

UK:

The 2300MHz band (2310-2390 MHz) is considered as a “prioritised band for release” in the spectrum strategy document19 issued by the Department for Culture, Media and Sport in March 2011, which sets the target of releasing 500MHz below 5GHz from the public sector by 2020.
