Samsung Presented New Flagship Galaxy S8 and S8+

Samsung today introduced its two new flagship smartphones Galaxy S8 and the Galaxy S8+ for the year 2017. The Galaxy S7 Edge gets two successors, which differ mainly by the display size: the Galaxy S8 has a 5.8 inch display while the Galaxy S8+ has a 6.2 inch display. Both the display of the S8 and the S8+ is rounded on both sides, a version without edge display is no longer available. The highlight is certainly the almost frameless design of the Samsung Galaxy S8, the display occupies nearly the entire front, the frames above and below the display are significantly thinner compared to the Galaxy S7. It’s said the Galaxy S8 would be available in the market at the end of April 2017.

 

Design and display
 
Visually, the Samsung Galaxy S8 and the Samsung Galaxy S8+ differ only in size. The S8 dimensions are 148.9 x 68.1 x 8.0 millimeters and weight is 152 grams, the S8+ dimensions are 159.5 x 73.4 x 8.1 millimeters and weighs 173 grams. The display has an aspect ratio of 18.5: 9 on both devices, so the devices are very narrow compared to 16: 9 devices with the same display diagonal. For comparison: an iPhone 7 with 4.7 inch display (16: 9) is only 0.8mm narrower than a Galaxy S8 with 5.8 inch display.
 
 
The design is broadly similar to that of the Galaxy S6 Edge and Galaxy S7 Edge, the device consists largely of glass, only the frame is made of metal. However, due to the large display, the home button has given way to software buttons and the fingerprint sensor has been placed on the back side of the camera.
 
 


Technology and software 

 The Samsung Galaxy S8 is one of the first smartphones to support LTE Category 16. This allows extremely high speeds to be reached via the mobile network, depending on the extent of the network up to 1 Gbit/s in the downlink. As a processor, there is a octa-core Samsung Exynos 8895 with 64Bit, 4 x 1,7 GHz and 4 x 2,3 GHz. In other markets a Qualcomm chipset is installed, the performance should be comparable. The memory is 4 GB and the internal memory measures 64 GB (UFS 2.1 technology, via MicroSD expandable). The Galaxy S8 have versions with single sim and dual SIM functionality for different markets and carriers, the sim type is Nano-SIM.
 
 

 The back camera of the Samsung Galaxy S8 offers a resolution of 12 megapixels and has an f1.7 aperture. The sensor works in the 4: 3 format, who would rather take photos in the 16: 9 format, has to deal with a lower resolution. The camera on the front takes photos with up to 8 megapixel resolution and also offers a f1.7 aperture. In the WLAN area, the Galaxy S8 offers a very modern equipment. The 802.11ac standard is supported with MU-MIMO antenna technology, in combination with a modern MU-MIMO router, you should get significant speed advantages. The Galaxy S8 also supports NFC and Bluetooth 5.0 as well as various satellite navigation systems.
 
 


As an operating system, Android is used in version 7.0, of course again with a Samsung-adapted surface. The always-on display has been adapted in such a way that a home button is also visible when the display is switched off, since the physical home button has been lost in comparison with its predecessor.
 


Battery 

The Samsung Galaxy S8 has - like the Galaxy S8+ - a permanently installed battery, which cannot be removed. The capacity is at the S8 3.000 mAh, while in the S8+, it is 3,500 mAh. The two devices support wireless fast charging as well as fast charging via the USB type C connector. By the way: in contrast to the Apple iPhone 7, Samsung Galaxy S8 does not have the 3.5mm audio jack connection, so you can use normal headphones and is not dependent on adapter or Bluetooth.
 
 


Price and availability 

 The two versions of the Samsung Galaxy S8 can be pre-ordered from now on and until the 19th of April in the Samsung Online-Shop as well as www.4gltemall.com . From the 28th of April, the Samsung Galaxy S8 and S8+ will be available in the colors "Arctic Silver", "Midnight Black" and "Orchid Gray".

TP-Link M7650 – Powerful Mobile Hotspot  
 
The new portable 4G router looks smart. In order to meet the ever-increasing maximum bandwidths in the LTE networks, a modem has been installed, which the Internet speed could achieve at up to 600 Mbps ( Cat. 11 ) via LTE accesses. The upload is, however, with a maximum of 50 Mbit/s. At the moment (at the end of March 2017) the manufacturer didn’t release detail specifications of this new model. Therefore, we cannot known all the technical specifications, such as the dimension and weight. However, TP-Link confirmed, among other things.
 
 
 
The first thing, the M7650 could reach download speed up 600 Mbit/s. The WiFi module of the M7650 makes a good job here, as up to 867 Mbit/s are implemented via a 5 gigahertz frequency. Devices that do not support WLAN at 5 GHz can get network with 2.4 GHz. With this spectrum, up to 300 Mbit/s can still be implemented in the download. This mobile LTE router should not be blamed for the battery life. According to the manufacturer, with 3,000 mAh rechargeable battery, a maximum of 15 hours of continuous operation is possible. A mobile device can not only be connected with the M7650 via hotspot, but also configure the router.    
 
The Chinese corporation TP-link does not show a new design for M7650 so that it can be special out of the mobile gadgets; it just follows the appearance of the M7310. There is a color mixture of silver and black and an informative TFT display. All information relevant to the operation is displayed on the latter, including the LTE signal strength, the battery status, the current speed or the network operator identification, everything is clear. 
 
 
The display measures 1.44 inches in the diagonal, it can be operated via physical buttons. It’s a pity that TP-Link M7650 does not have a touch screen while the similar model Netgear Aircard 810s already provides touch screen for users. What’s more, the integrated memory card slot accommodates microSD cards with a size of up to 32 GB.   
 
 
 Here now, the TP-link M7650 is not yet available on the market. There is another model Netgear Aircard 810s which has similar specifications and it's already available on the market. If you prefer TP-link M7650, 4G Mobile Broadband Mall (www.4gltemall.com) accept pre-order of this future-proof 4G mobile hotspot. Once we get this TP-link M7650, we would take test and show our report soon.

4.5G - LTE Advanced Pro

LTE Advanced Pro or 4.5G is a very up-to-date topic in the mobile world. Although the LTE successor 5G is talked much, 4.5G is already used by the network operators, and it already active and already contains many features, which will later also play a large role in 5G. Many carriers in Europe, such as Vodafone and Telekom, have already carried out initial tests with 4.5G or LTE Advanced Pro, which was launched to market shortly before. What you will understand exactly under 4.5G is to be explained in this article.

 

 

 

4.5G: Features

Right from the start: whether 4.5G or LTE Advanced Pro is the same. It is the successor of 4G and/or LTE Advanced. According to the Global Mobile Supplier Association (GSA), a network must support the following standards to be officially considered a 4.5G network: One of the following features:

  • Ultra short latencies, ULL (ultra-low latency)
  • An extension for machine communication, eg NarrowBand-Iot (NB-IoT) or eMTC

Additionally, at least one of the following features:

  • 4 or more bundled downlink frequency ranges (4CC Downlink Carrier Aggregation, CC here for Component Carrier)
  • The aggregate spectrum aggregated with carrier aggregation exceeds 60 MHz
  • 2 or more bundled Uplink frequency bands (2CC Uplink Carrier Aggregation)
  • Advanced MIMO antenna technology (eg 4 × 4 MIMO, 8 × 8 MIMO, Beamforming, Massive MIMO)
  • 256QAM modulation in the downlink
  • 64QAM modulation in uplink
  • License Assisted Access (LAA), ie the additional use of unlicensed radio spectrum, eg in the 5 GHz frequency range
  • Vehicle-to-X communication (V2X)
  • Mission Critical Push to Talk (MCPTT)
  • Network extensions for improved indoor positioning

 

 

 

 

The V2X communication is already being tested under some carriers’ networks, for example Vodafone. Recently, there was a corresponding demo at the Mobile World Congress together with the network equipment supplier Huawei. In theory, Vodafone could also bundle significantly more frequency spectrum and thus introduce 4CC or 5CC carrier aggregation, but the provider has so far restricted itself to Triple Carrier Aggregation (LTE 800 + LTE 1800 + LTE 2600).  

 

NB-IoT is used in the LTE band 8, that is to say in the 900 MHz range parallel to GSM, and band 20 (800 MHz) is also to be used. Up to now Telekom has bundled three frequency bands by means of carrier aggregation. In the future, however, the vendor could easily add additional carriers such as Band 8 (900 MHz) or Band 1 (2100 MHz). A significant increase in the downlink speed should therefore be possible in the near future. The use of 4 × 4 MIMO is also being tested in some locations and within the framework of its 5G, Vodafone has long been working on measures to further reduce latencies. Surely these ULL features will also be implemented in the 4.5G network.  

 

 

 

What does 4.5G bring to the end customer?

 

Many 4.5G features are particularly interesting for communication with machines or between machines, eg NB-IoT or ULL. As an end customer with a modern smartphone (from LTE Cat11 or newer, eg Huawei P10 or LG G6), there is one benefit: the maximum possible speed is much higher than what is so far. The expansion of LTE on other frequency bands, eg band 8 or band 1, will allow better network coverage in some places. Massive MIMO, in particular, will have a significant improvement in the average speed for the individual user, particularly at locations with very high capacity utilization.
