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.

Huawei Ascend P2 4G LTE Smartphone Review

Huawei Ascend P2 4G LTE Smartphone is a good Android phone with LTE technology and quad-core processor. It comes out at the begging of 2013 and the key feature should be that HUAWEI Ascend P2 could support LTE category 4 and reach the peak speed as 150Mbps. And the smartphone could work a LTE cat4 Mobile Hotspot. Today, we will have a review of this new samrtphone and give users some advice on this new smartphone.

 

     

Huawei Ascend P2: First impression  

 

 

HUAWEI Ascend P2 is the successor to the HUAWEI Ascend P1 3G Smartphone, which is called the world’s slimmest smartphone and it’s Huawei's first real high-end smartphone. With the Ascend P2, HUAWEI wants to establish in the upper class.   Whether the target could be achieved from HUAWEI Ascend P2, this new Smartphone incorporates many attractive specifications, which is important for all the newcomers. HUAWEI Ascend P1 is with LTE, NFC, quad-core and 13-MP camera, and it brings all the key data corresponding with new and better customer experience. However, the plastic materials give some discount for the upper class. While it is very solid and meticulously crafted, it would not creak and squeak. However, its hepatics are not on top-class level and cannot keep up with the current high-senders as the Xperia Z and HTC one.    

 

The glossy back cover is not removable, and shows prone to fingerprints, but closes very clean and exemplary with the rest of the housing components. Bases on this, Huawei have worked very solid.      

 

 

Special: All news and tests from Mobile World Congress 2013    

 

From less quality look and feel independently, HUAWEI Ascend P2 makes an excellent impression. The touch screen responds quickly and absolutely reliably to each entry, no one has bothered bucking the test on the show. The performance as a whole is on a very high level.      

 

 

The screen immediately convinced, he draws content and especially writings very sharp. The presentation precipitated with natural colors and sharp contrast. User can reach any corner of the screen comfortably, even with one hand. In general, the Ascend P2 is pretty handy and fits comfortably in your hand.

 

The new Emotion UI by Huawei can also convince serves based on Android version 4.1 Jelly Bean. The surface works without classic main menu; all installed applications are organized directly on the home screen, either in folders. While at first this seems odd, but certainly has its appeal. The internal memory is not expandable, but the memory card could be extended up to 16GB.

 

 

 

Huawei Ascend P2 Features:

* Fast LTE Internet

* NFC * Bluetooth 4.0

* MHL via the micro

-USB connector

- no HSPA+

- Memory not expandable

- Permanently installed battery    

 

 

Huawei Ascend P2 Operation:

* Good performance

* High-resolution and high-contrast display

* sound processing

- Back is prone to fingerprints

- Hepatics not at the top level    

 

 

HUAWEI Ascend P2 Specifications:

* Dimensions: 136 x 67 x 8 mm

* Weight: 122 g

* Display: 4.7 inch, 720 x 1200 pixels

* Processor: 1.5 GHz quad-core processor K3V2

* Platform: Android 4.1

* Memory: 16 GB

* Battery: 2,420 mAh  

 

In conclusion, as the top telecommunication equipment supplier, HUAWEI may be a new player of smartphone, but we can see the quality of the smartphone is better and better. Even though HUAWEI is eager to gain the high-class market, but it seems there will be long way to go. HUAWEI Ascend P2 should be a new LTE smartphone worth to wait and have.   If you want to check more 4G LTE smartphones, welcome to 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.   If you want know more details of them, welcome to buy it from www.4gltemall.com .
