LTE and WLAN Trend in 2013

Mobile Internet will dominate the future. Per current data, it indicates the increasing number of data flat rates and the proportion of mobile Internet users. In this case, mobile internet is becoming increasingly attractive, which is mainly due to the speed of data transmission over wireless connections.

 

 

Rural Users Benefit from LTE

 

Especially the development of networks for the operation of the 4G Wireless standard Long Term Evolution (LTE) will accentuate the trend towards the mobile Internet. The mobile Internet operation via Smartphone or tablet makes 4G internet more attractive. For private providers or enterprises in rural areas, LTE is an affordable alternative to a fixed line, which can often provide in depressed areas where no broadband Internet.

 

WiFi is Faster

 

However, the WLAN radio network will achieve in the future faster data transfer rates. The conventional network via Ethernet is therefore increasingly interchangeable and WiFi make interesting reading for more public institutions. For a broadband Internet connection is thus save much cost.

 

In data centers, data will continue to be converged to server-storage network systems. The modular connection allows a flexible adaptation of the hardware utilization to each customer.

 

The trend of “ALL IP” still continues. With “all IP”, the use of all telecommunications services is meant by a supplier. It is worth taking this method for medium to large businesses.

 

LTE in Release 10—Ten Faster than LTE

The 3rd Generation Partnership Project (3GPP) standardized wireless technology Long Term Evolution (LTE). 3GPP is a consortium of several institutes.

 

The project also defines standards for other mobile technologies such as HSPA. In Release 10, LTE advanced is outlined, 9 expansion of LTE in Release 8 and Release 10 was introduced in 2009 as a proposal and completed in 2011.

 

 

100 Megahertz needed

 

The first 4th generation wireless technology, LTE advanced theoretically reaches up to 1 gigabit per second (GB/S) for receiving data (download) and up to 500 megabit per second (Mbit/S) for sending data.

 

Just like LTE in Release 8 and 9 uses LTE advanced is a 16-fold quadrature amplitude modulation (QAM), a technology that allows more data to be transported on a wave.

 

In contrast to the previous technologies, LTE advanced 100 Megahertz is used to frequency bandwidth, which can be summarized from independent frequency bands. This is necessary, because no operator called integrated 100 MHz of LTE frequencies into his own. This frequency bandwidth is shared by eight independent antennas, which must be installed at the transmitter as at the receiver. This technology is referred to 8 x 8 MIMO (Multiple Input Multiple Output).

 

 

What’s the Difference between HUAWEI E5331 and HUAWEI E5332?

Following the mobile WiFi HUAWEI E5331, HUAWEI had released another sister model HUAWEI E5332 HSPA+ 21Mbps mobile WiFi Hotspot. So what’s the difference from the two WiFi hotspots?

Huawei-E5331 VS HUAWEI E5332

 

There is no doubt that HUAWEI E5331 is the best seller in HUAWEI E5 Mobile WiFi family. Based on good performance, cool appearance and good price, HUAWEI E5331 becomes the most popular pocket WiFi since its release from HUAWEI.

 

 

HUAWEI E5332 comes out to compensate some functions that HUAWEI E5331 can’t finish. For example, if the users use E5331 in rural area where the network signal strength is weak, the internet link speed may be too slow to bear. At this time, you may think find some ways to enhance the signal. To add an external antenna is the usual way to solute it, however, HUAWEI E5331 don’t have the port for external antenna, then HUAWEI E5332 comes out.

 

So the main difference between HUAWEI E5332 and E5331 is that HUAWEI 5332 has external connector for antenna, which is to give solution for users living in areas with weak signal. With the connector, HUAWEI E5332 is a little bit thicker than HUAWEI E5331. In this case, it looks like HUAWEI E5151 WLAN Mobile 3G Router.

 

But for most users, HUAWEI E5331 is enough because actually, there is built-in antenna in the two mobile WiFi Hotspot. And if you choose HUAWEI E5331, it proves the coverage of network in your area is good enough; users don’t need any more external antenna. And with external antenna port, the cost of HUAWEI E5332 is a little bit expensive than E5331. But you still need spare antenna for HUAWEI E5332, you could buy it from 4gltemall.com .

LTE – Up to 300 Mbit/s Per Second for Release 9

The 3rd Generation Partnership Project (3GPP) standardized wireless technology Long Term Evolution (LTE). 3GPP is a consortium of several institutes.

 

 

The project also defines standards for other mobile technologies such as HSPA. In December 2009, the Release 9 followed as the second standard, which contained LTE after the year before the release had 8 defines first LTE.

 

Four independent antennas

 

LTE Release 9 help you reach computationally up to 326.4 Mbit/s for receiving data (download) and up to 86.4 Mbit/s for sending data (upload).

 

Compared to 172.8Mbit/s download, which can be reached with Release 8, the theoretical speed was almost doubled. These Technologies make it more possible. As with Release 8, a 16-fold quadrature amplitude modulation (QAM) is used, a technology that enables more data to be carried on a shaft.

 

In addition, up to 20 MHz frequency bandwidth used. However, Release 9 is used in contrast to its predecessor up to four independent antennas at the transmitter as the receiver; the same send or receive data. This technology is called MIMO (Multiple Input Multiple Output).

LTE – Up to 172.6Mbit/s

The 3rd Generation Partnership Project (3GPP) standardized wireless technology Long Term Evolution (LTE). 3GPP is a consortium of several institutes.

 

The project also defines standards for other mobile technologies such as HSPA. In Release 8 of the 3GPP LTE in 2008 for the first time defined. Here, speed and technology used were committed.

 

Different Technologies for Increasing the Data Rate

 

With Release 8, the theoretical top speed with LTE on 172.8 Mbit/s when receiving data (download) and up to 57.6 Mbit/s is limited to send data.

 

 

The speeds are made possible by a number of technical parameters. First, a 16 fold quadrature amplitude modulation (QAM) is used, a technology that enables more data to be carried on a shaft.

 

By a plurality of antennas at both transmitters on the receiver side as the speed is increased in both directions as well. This technology is called MIMO (Multiple Input Multiple Output). On LTE Release 8, two independent antennas are used (2 x 2 MIMO). Essential for the increase in speed is also the frequency bandwidth of the connection. In this case, up to 20 MHz, in order to transmit data.

 

 

In reality, the network operators are indeed technology such as MIMO and QAM are available, but there is a lack of sufficient bandwidth. This is spread across multiple network operators, so that in practice 50 to 75Mbit/s are technically feasible in the download.

 

 

 

LTE Standardization

3GPP is initiative responsible for the standardization of LTE mobile technology. 3GPP Stands for Third Generation Partnership project.

 

The initiative focuses on the standardization of LTE and third generation wireless technologies such as UMTS.

 

Technical specifications of LTE

 

In various releases since 1999, the 3GPP initiative has published technical specifications for different areas of mobile communications technology. The release 8 focuses on the standardization of LTE technology and is the most recently completed. In releases 9 AND 10 further standardization of LTE technology are made.

 

Release 9 is concerned with improvements and enhancements of HSPA and LTE Release 10 defines the technical specifications of LTE-Advanced. For Release 9, the development of the remaining issues to be completed in March 2011. Release 10 is still under development, a completion data is unknown.

 

About 3GPP

 

3GPP was created in 1988 with the goal of creating a global mobile applicable third generation system. Practically to the standardization by 3GPP to enable the users to get in as many networks worldwide with the same equipment, the same services as in his home network.

About this Organizational Partners worldwide a majority of all mobile operators, manufacturers and regulators is organized in the 3GPP initiative.

HUAWEI E5151 Mobile WAN LAN 3G WiFI Router Review

HUAWEI E5151 3G Mobile WiFi Hotspot (also named HUAWEI E5151s-2) is one of the new mobile 3G router from HUAWEI. Focus on the application of businessmen, HUAWEI design this new model with one Ethernet port to input HUAWEI E5151 and transfer data to WiFi signal so that users could access internet. This is the special and key features of HUAWEI E5151 Pocket WiFi Hotspot.

HUAWEI E5151 face

Today, let us have a look at HUAWEI E5151 mobile WiFi and it’s specifications.

 

HUAWEI E5151 is in pocket size, like other HUAWEI E5 pocket WiFi models, which makes it very easy to take in hand or pocket. For most of users, it could be taken outdoors or with a trip, however it would not take much space in luggage. To meet the Ethernet connector, HUAWEI E5151 is thicker than other HUAWEI E5 mobile WiFi hotspots.

 

On the face, there is a LED screen which is to indicate the working status of this mobile WiFi. At the left side, it’s the HUAWEI logo. When it’s working, it will show the connection users, signal strength of 3G, battery status and SMS. At the right side, it’s the power button.

 

 

On the back, it’s a logo of HUAWEI mobile WiFi. With changeable battery, it could keep working 4 -5 hours and almost one week standby time. Below the battery, it’s the slot for 3G SIM card.

 

 

The SSID and WiFi key is on the back cover of HUAWEI E5151. Through this, you will connect the WiFi and surf internet.

LTE – Investments, Costs and Profits

Mobile operators have pulled out of the expensive purchase of UMTS licenses, the expensive construction of UMTS networks and the subsequent price of their teachings battle for customers.

 

But with LTE, users pay only a fraction of the transmission frequencies. For network construction, the price is the decisive criterion in selecting among the network equipment. And customers for data services in LTE networks will have to pay significantly more than what they have been accustomed to from UMTS networks.

 

 

UMTS: The more data, the more cheaper

 

The mobile plan has a problem; you need to inject more data into ever cheaper prices through their wireless networks. Since the new technology LTE is just right, the cost of production for fast data transmission in mobile communications should be lower. The cost per bit is lower for the network operators from four to ten times more than in HSDPA. This is also related to the fact that through new applied in LTE radio technologies, such as multiple-antenna method MIMO or the new modulation schemes OFDMA, with ten times more. LTE phones can be provided at a location with high speed internet than with UMTS. With LTE, so the profit margin is the mobile data tends to increase and the number of potential customers multiplied at one location.

 

 

LTE Expansion Cheaper than UMTS

 

The cost of the LTE expansion circulates different numbers. The bidding for the frequencies is already certain.

 

Expenditure incurred in the bidding for the frequencies, the cost for network deployment. The US firm Aircom, a network specialist, estimates that a mobile operator in Central Europe needs to spend about 670 million euros for the LTE network construction in the first year.

 

Lot of costs should come together after all, it must not only upgraded base stations to LTE or LTE base stations will be built, it must be a new IP-based core network to be created. And finally, the data lines must be upgraded from the base stations to the new core network to process the large amounts of data, because what good is fast wireless network if it only blcks the access to the core network. This looks like a high investment.

 

Pressure on network equipment

 

In order to make sense economically, the LTE expansion should cost only a fraction of what was spent on the construction of UMTS network, so the experts explain the Finnnish IT consultancy Rewheel. My solution to this dilemma: The network equipment should rethink their pricing somewhat.

 

New tariffs: LTE’s are not as bargain

 

After the business model was not a UMTS rousing success for many years, the mobile operators want LTE would not have to wait due to the investment pays.

 

And that probably means that they do not just invest less than in the UMTS networks, but they will charge higher prices at the retail level.

 

LTE is surely not only once at a bargain price.

Three Huawei B183 Webcube Home Broadband General Review

The UK’s operator Three had recently released two new broadband routers for home, the model numbers are HUAWEI B183 and HUAWEI B153. They are fixed line broadband and is the perfect companion for Students who need a broadband connection in there diggs, and the most important feature is (you don’t need a landline to use it) just plug into your mains and Three will do the rest.

 

Today, let’s have a review what’s the features of the Webcube White HUAWEI B183 home broadband Router and what it can do for us.

Appearance

Webcube HUAWEI B183 is in a very classic design, looks like an hour glass, but has a sudden glance; you may think it’s a humidifier. In simple white, the cube shape is very attractive, different any other home router, which make it looks more like a home white goods, not just a network router.

 

On the top side, there is signal strength indicator, if it’s not working, you may not be able to see it. And with the single strength indicator, you will see the Power and WPS button. And there is logo on this face, sometime it’s “3”. 4GLTEmall.com provider unlocked HUAWEI B183 with HUAWEI logo, no contract and no limit. The top cover could be departed from the below part, at the side of the top cover, there is external antenna port and reset button covered by a slip.

Another side of the top cover, USIM card slot and network indicators are also configured. What’s more, there is USB port around, which is for test purposes only, not for users. So for most of the users who had get it first, they may don’t know how to use, where to plug SIM card, where to power it on. From above image, you will find details part of HUAWEI B183. Now it’s easy to operate to connect network.

HSPA+ Technology

HUAWEI B183 Home Broadband from Three with the latest HSPA+ offering up to 21.1Mbps download and up to 2 -5Mbps uploads, but you can expect to receive download speeds in excess of 10Mbps which without a landline is exceptionally good. This is also an exceptional deal for renters too who only wish to use the internet occasionally or are moderate users, also great for customers in rural areas of the UK where accessing the internet is hard to acquire.

 

 

Entry Level Broadband

The B183 Webcube offers up to 5 different connections at the same time enabling other family members to be online simultaneously, with a good wireless range extended up to 30 meters away from the cube and you still get a perfect signal anywhere around your home.

 

Go Anywhere Broadband

The great thing with the Webcube B183 is how easy it is to carry to a friend’s home and set up in next to no time so you can share a connection with them, when you receive your B183 Webcube from Three you have a (pre-defined SSID and Network Key) that only belongs to you, in the box you will have your password and info to input, then you are able to use your new Webcube for the first time.

 

You may ask there is HUAWEI B153, what is it? Actually, HUAWEI Webcube B153 has almost the same appearance and size of HUAWEI B183. The main difference between HUAWEI B183 and HUAWEI B153 is that B153 supports HSDPA 7.2Mbps while B183 support peak HSPA+ 21Mbps download speed. So if to get better network link, HUAWEI B183 is a good option, but if HSDPA 7.2Mbps can meet your requirement, HUAWEI B153 is a cost budget one for home router.

 

What is WiMAX?

WiMAX stands for Worldwide Interoperability for Microwave Access – an international system compatibility for access to microwave frequencies. It is in a sense competes with LTE – the technology, which we wrote about earlier, for the title of the next generation of mobile networks 4G. The reason is that both technologies provide a connection for mobile terminals (smartphone, laptop) with a sufficiently large radius of action. At the same time, there are similarities with the traditional Wi-Fi.

 

WiMAX is the wireless technology that provides theoretical data rates up to 1 Gb/s. Designed to solve the problem of the “last mile” access to the Internet.

 

 

The problem of the “last mile”, is a link from the equipment provider to the customer directly, by phone or Internet. For example, in Europe the most common channel is DSL, using ordinary telephone line with all its shortcomings. The idea to replace the wire telephone line radio channel with sufficient speed is very tempting – a minimum of inconvenience to the user and less dependence on fragile cables.

 

The name WiMAX «for nerds» is IEEE 802.16, which puts it on par with other telecommunications standards. And fixed WiMAX (includes communication with the fixed customer) applies standard 802.16d, while mobile WiMAX (communicate with client in motion) uses a modification of 802.16e.

 

The key difference stationary (fixed) and mobile versions – in the absence of a first opportunity to “transfer” of a customer from one base station to another. Naturally, some of the mobility of customer equipment within range of the base station (10 km) is possible. Mobile version of the report provides a current revision speeds up to 30 MB/s, while the fixed – up to 75 MB/s. The theoretical limit is around 1 gigabit.

 

Unlike Wi-Fi (IEEE 802.11), WiMAX not only uses the license free, and licensed frequency bands – from 2 to 11 GHz.  WiMAX range is much more than the Wi-Fi network, except for the transfer of the antenna. For the fixed network, as we have said, it is up to 10 km, while the mobile network is within a radius of 5 km.

 

 

The large scatter of operating frequencies creates serious problems of compatibility. For example, the optimal properties for the frequency range 2300 – 2700 MHz in most of the world is a licensed and used by intelligence services, which means that service provider will have to invest a lot of time and effort into getting permission. The range is 3400 – 3600 MHz is less problems with permissions, but penetrating power drops sharply, for example, for indoor reception may not be possible.

Finally, the cut-off frequencies of 6 GHz and above all can be used only in the line of sight due to the low penetration. For comparison, a rival LTE technology, which operates in the usual range of cellular communication in the area of 1800 MHz, has not these problems of penetration

 

The principle of the subscriber device (modem, phone) with WiMAX is similar both to work in the network, and to work with Wi-Fi access point. The device sends the request to the UE on the bandwidth allocation, and then logs in and gets your own channel. Then the authentication procedure and the device are issued IP-address: four-or six-digit (in a future release.) Calls to the WiMAX network will also implement IP-based, as in Skype – another similarity with the Wi-Fi-networks.
