LTE Surf Sticks

LTE Sticks are technically radio modems, meaning little combined transmitting and receiving equipment, which operate on different frequencies.

 

They can be connected via the USB ports to virtually any device such as a larger netbook, laptop or home PC. The sticks are in demand, such as to use abroad, or a change to a new and faster wireless data technology, and they are easy to replace. In addition to the relatively small size and low weight, this versatility and the slight changes are the greatest advantage of the sticks.

 

Even with the older data radio technologies of UMTS and GSM, sticks still dominates the modem market, other solutions such as built-in modem or modem card format to be used much less frequently. For the majority of users, LTE Surfsticks will be the solution that makes mobile internet the fastest and easiest access.

 

The new LTE Sticks come from the Far East, currently dominate the South Korean manufacturer Samsung, LG Electronics and Pantech market, China’s Huawei tries to win over new entrants.

 

So the first LTE Stick was Samsung GT-B3740, which is developed by Samsung in Vodafone Brand. The next stick from Swedish-finished network operator Telia Sonera is the GT-B3710 from Samsung. Meanwhile, there is B3730, which dominated alongside LTE is UMTS and HSPA, GSM and EDGE, as well as wireless technologies. The device sends in LTE mode on the frequency 2600MHz. It is also used in the Vienna LTE network of the Austrian mobile operator A1 Telecom Austria. The B3740 is likely to be an optimized version with a similar standard.

 

The second LTE stick comes from Chinese mobile phone supplier, HUAWEI, it is HUAWEI E398. The device was tested in the LTE network of O2 and is now available at Telekom from the second half of 2011. In Austria, it is the mobile operator A1 Telekom Austria offered on its website.

 

 

Global Supply of LTE Sticks

 

There are very few data sticks, which are with wireless data LTE technology, so pure LTE Sticks have others technologies backward, such as UMTS, GSM and CDMA 2000 network to send and receive. Overall, a clear trend is emerging to stick with multi-technology, pure LTE Data sticks are shunned by the mobile operators.

 

 

The Pantech UML290, originates from South Korea, and sells for US Verizon Wireless LTE network. It’s like the stick used in Scandinavia and Austria from Samsung, sends an older and slower wireless technology on board. In the case it is spread in the U.S. CDMA 2000, and therefore he receives on 800 Mhz and 900 Mhz. For LTE reception, it is in the range of 700 MHz road.

 

The second stick, Verizon Wireless LG VL600 of the South Korean manufacturer LG Electronics. With LTE, it’s in the 700 MHz band travelling with the frequency used the U.S. 3G CDMA 2000 technology, it can send and receive on the 800MHz and 1900MHz band. LG Electronics also has the LD 100 model that is used in Japanese LTE network of Docomo. It also speaks several wireless data technologies, besides LTE, there is UMTS and HSPA, plug for the Japanese to travel abroad, GSM and GPRS are also included. GSM will be gradually switched off in Japanese networks.

 

What to look for LTE Sticks

 

All LTE Sticks on the market are significantly larger than the surf sticks with pure UMTS or GSM technologies; they therefore require more space on your laptop. If two or more USB ports close together, this may lead to another USB ports blocked. Therefore a rotatable mechanism for raising the stick is very useful to save some space with a bent 90 degrees stick, and most of these sticks have rotate mechanism.

 

Pure LTE Sticks can only be used where LTE is available. Since the LTE network is expanding coverage in many areas, it would take many years for LTE network to cover every corner. Therefore in some areas, you have to use other technologies UMTS and GSM, and the associated wireless data technologies HSPA and EDGE, to dominate the modem.

 

Several sticks offer external antenna connectors; one is for the older mobile technologies and one for LTE. This is an important consideration when buying, LTE will be predominantly at home or hospital use, we recommend you might install an LTE external antenna.

LTE Smartphones

The first LTE Smartphone brough the Korean company Samsung with model “Craft” on the market, it is from the regional provider MetroPCS LTE in its LTE network in Las Vegas and currently offered in many other urban regions.

 

The Craft dominated the radion data technology LTE and common in the US technology of the third generation mobile CDMA 2000. The latter is also urgently needed, as is still the problem of voice transmission through LTE unresolved. Must the “Craft”, when a phone call is made, switch to the CDMA network. Then abort the current download and it can simultaneously send and receive in two technologies and the unit now not even. In short: if you surf and there is a phone call, you can fly from the Internet.

 

According to the manufacturers and mobile operators 2011 is the year of LTE smartphones. This applies first of all to the market in the U.S. Here is the LTE rollout in the area so far advanced that there are enough customers for such devices.

 

Besides the already mentioned Craft by Samsung, there are no Metro PCS, a second LTE smartphone of the Korean Samsung “Galaxy Indulge”.

 

The “Thunderbolt”, were announced as the new LTE Smartphone by the Taiwanese company HTC, and the US. Mobile phone manufacture Motorola model “Bionic” and the Korean LG model “Revolution”.

 

Tips for LTE Smartphones

 

And LTE Smartphone should be proficient in addition to the latest and fastest data transfer technology, the transmission in UMTS networks including HSPA(and possibly HSPA+) with GPRS and EDGE and GSM networks in the second generation mobile. It must be as quickly as possible. Finally, it will take years for the LTE networks everywhere. And many customers want apart from the major urban centers to the mobile internet.

 

When purchasing a LTE Smartphone, an important point is to know the telephone solution. This equipment is recommended to perform without net change, when you call out. However, currently, it’s not yet clear when devices will have this capability on the market.

What is GSM, EDGE, GPRS, UMTS 3G, HSDPA, HSUPA, LTE

What is GSM?

The acronym GSM is a mobile communications system and means “Global System for Mobile Communications”. GSM supports data rates of max. 14.4 kbit / s GSM is the successor system of A, B and C networks and is commercially available in Germany since 1992.

The Global System for Mobile Communications (formerly Groupe Spécial Mobile, GSM) is a standard for fully digital mobile networks, which is used mainly for telephony, but also for circuit switched and packet-switched data transmission and text messages (short messages). It is the first standard of the so-called second generation (“2G”), replacing the analog systems of the first generation (in Germany: A-line, B-grid and C-grid) and is the world’s most popular wireless standard.

What is UMTS (UMTS broadband, 3G)?

The acronym stands for UMTS “Universal Mobile Telecommunication System”. UMTS is a mobile system with speeds of max. 384 kbit / s UMTS is the successor of GSM and commercially available since 2004 in Germany.

The Universal Mobile Telecommunications System (UMTS) is a wireless standard of the third generation (3G), with significantly higher data rates (up to 21 Mbit / s HSPA +, otherwise max. 384 kbit / s) than with the wireless standard of the second generation (2G ), the GSM standard (up to 220 kbit / s in EDGE;. otherwise max is 55 kbit / s in GPRS), possible.

The ITU had UMTS selected for IMT-2000, and it is therefore one of the standards for the third generation mobile communications. Originally, the ETSI (European Telecommunications Standards Institute) had standardized UMTS, today the 3rd Generation Partnership Project (3GPP) maintains it further. The standard is constantly being expanded, for example, increased the maximum HSDPA receive data rate (downlink). For the transmit data rate comparable with HSUPA technology is available.

 

What is EDGE?

EDGE means “Enhanced Data Rates for GSM Evolution” and is a transmission technique in GSM networks, the transmission rate can be increased theoretically up to 220 kbit/s.

Enhanced Data Rates for GSM Evolution (EDGE) refers to a technique for increasing the data transmission rate in GSM networks by introducing an additional modulation method. GPRS with EDGE data services to E-GPRS (Enhanced GPRS) and HSCSD be extended to ECSD.

EDGE represents an evolution of the GSM technology represents It is basically a GSM with more bits per baud. [1] EDGE with moderate effort can be integrated into mobile networks as it does not disturb the already existing mobile telephony. Essentially, it is necessary to update the software of the GSM base station and optionally to replace individual components.

 

What is GPRS?

GPRS is “General Packet Radio Service” and is a service between UMTS and GSM networks of permanent connection to devices sustains and transmits data packets only when necessary.

General Packet Radio Service (GPRS) (German: “General packet radio service”), the name given to the packet-based service for data transmission in GSM networks.

If GPRS is activated, only virtually, there is a permanent connection to the remote site (the so-called always-on mode). Only when real data is transmitted, the radio room is occupied, otherwise it is free for other users. Therefore, no permanent radio channel needs (as with CSD) reserved for a user to be. GPRS bills are therefore mainly dependent on the quantity of data transferred rather than connect time. However, this is also dependent on the particular contract terms with the operator.

Unlike the circuit-switched (English circuit switched) CSD data service GPRS is packet-oriented. That is, the data are converted at the transmitter into individual packets, transmitted as such, and the receiver re-assembled.

What is HSUPA?

HSUPA means “High Speed Uplink Packet Access” and is a technique used in the UMTS mobile communication system, the upload speeds up to 5.8 Mbit/s.

High Speed Uplink Packet Access (HSUPA) is a transmission method of the UMTS mobile radio standard that allows higher data rates in the uplink and reduces the round trip time (often referred to as ping). HSUPA Category 6 were up to 5.76 Mbit / s and category 9 (Release 9) up to 23 Mbit / s can be achieved. HSUPA is part of Release 9 of UMTS.

 

What is HSDPA?

HSDPA means “High Speed Downlink Packet Access” and is a technique used in the UMTS mobile communication system, the download speeds of currently 3.6 Mbit/s to 7.2 Mbit/s. HSUPA is developed commercially since 2007 in Germany.

High Speed Downlink Packet Access (HSDPA, 3.5G, 3G + or UMTS broadband) is a data transmission method of the cellular standards UMTS, which was defined by the 3rd Generation Partnership Project. The method enables DSL-like data rates in mobile networks.

HSDPA is available in Germany, among others by the network operators Vodafone, E-Plus, O2, and telecom and in Switzerland by Swisscom, Sunrise and Orange. In Austria operate the A1, T-Mobile, Orange and Three HSDPA networks.

What is LTE?

LTE means “Long Term Evolution” and a mobile radio system with very high data rates. Long Term Evolution (LTE) is a wireless standard of the fourth generation (4G standard), which can carry up to 300 megabits per second to achieve much higher download speeds. Someone may ask, in the wireless phone abbreviation 4g, what does the “g” stand for?  The answer is “g” stand for Generation. The GSM, GPRS and EDGE are 2G (second generation)networks, UMTS/WCDMA/HSPA+/DC-HSPA+ are 3G(third generation) networks, LTE(TD-LTE/FDD) is 4G(Forth generation) network.The basic scheme of UMTS LTE is maintained. Enables rapid and cost-effective retrofitting the infrastructure of the UMTS technology (3G standard) on LTE-Advanced is possible. LTE-Advanced is backward compatible to LTE.
