Unlocked Rogers LTE Aircard 330U from Sierra Wireless General Review

You may had seen a 4G LTE Modem which support 4G Band 4(1700/2100MHz) or 4G LTE Surfstick which is for 4G FDD Band 7 (2600MHz), but do you know any 4G USB modem that could support them together?

 

Today, we will recommend a 4G Aircard which could support the 4G LTE FDD Band 4 and Band 7 simultaneously. The model number is Rogers AirCard 330u LTE Rocket Stick. This is the successor of Sierra Wireless AirCard 320u. They are both from Sierra Wireless. The difference between them is that Aircard 330U is capable of LTE FDD Band 7 and Band 4, but AirCard 320U could support band 3 and band 7.

 

 

 

The Rogers LTE AirCard 330u looks cool in red color, but it's unlocked to Rogers network. It means the AirCard 330u could support any operators' SIM card.     Just like the brother model AirCard 320u, 330u is in square shape and it's bigger than AirCard 306 or 308. The USB could rotate for 180 degree. On the front, There is logo of Rogers and one the back, there is printer of "4G LTE" on it. Below the "4G LTE", we can see the icon of the manufacturer "Sierra Wireless" logo, and the indicator of data transmission.  

 

 

 

Open the back cover, we could see there is a stick indicating the model number "AirCard 330u" and the IMEI number of the 330u. Belie the stick, we can see the SIM card slot and MircroSD card slot. At the side of the SIM card slot, there are two external antenna connectors for MIMO. They are covered by two small cap, user need open the cap and then connect the external antenna.

 

 

 

The connector of the external antenna is TS-9 model, so if you want buy external antenna for AirCard, you could check here: http://www.4gltemall.com/external-antenna-for-huawei-4g-l...  

the 4G Antenna is also usable for Aircard 320U and 313U. 

 

 

After plug the two external antennas, the data link speed would improve obviously. The AirCard 330u is apt for North America 4G LTE networks band 13 and band 7, so it could also roam in Europe or Asia. In conclusion, AirCard is a cool USB modem that will be a good gadget for 4G networks.

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 .

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.
