What is 4G LTE Standard?
LTE stands for 3GPP (3rd Generation Partnership Project) Long Term Evolution. operating under a name trademarked by the European Telecommunications Standards Institute (ETSI). It is actually the technology used by telecom industry players to serve as an upgrade for them to offer a true fourth generation or 4G service.
Most broadband networks today still operate under third generation or 3G/3.5G/3.75G technology networks that include Global System for Mobile communications or GSM and Code Division Multiple Access or CDMA. With the LTE technology, users can expect to get a whole new range of benefits and services. For users, the new technology promises faster speeds and lower costs. For networks, it means enhanced capacity.
Difference Between LTE and Dual Carrier HSPA+
The main difference between LTE and Dual Carrier HSPA+ is that the latter is built on existing or 3G technology while the former is an entirely new network. Therefore, if you have a 3G compatible phone, it will work on an HSPA + network but it will not be able to access an LTE network. Another significant difference, of course, is that an LTE network is faster than the dual carrier HSPA+. LTE can reach speeds of up to 100Mbps on the downlink and 50Mbps on the uplink with latency of less than 10ms. This meets the specifications set by the International Telecommunication Union (ITU) for 4G networks. Dual carrier HSPA+, on the other hand, reaches 84MBps on the downlink and 22MBps on the downlink.
There are more differences between Dual Carrier HSPA+ and LTE. Dual Carrier HSPA+ is compatible with older technologies while LTE is not backward compatible with 3G networks. LTE uses OFDMA and SC FDMA in radio access networks with MIMO techniques while HSPA+ relies simply on MIMO techniques. HSPA+ has a fixed channel bandwidth at 5MHz and combines two channel while doubling data rates while LTE uses varying bandwidth of 1.4MHz to 20 MHz.
Where is LTE Available?
LTE is not yet widely available around the globe. In the US, Verizon is so far the only company offering LTE connectivity and has rolled out the service in 100 markets around the country.
LTE has also been released in European countries such as Germany, Austria, Poland, and the UK. Even if LTE is available in your market, it may not be available in the area of the market where you live. So it is wise to check first whether LTE is really available in your area before you get an LTE capable device.
New LTE Stick Modem
One of the first LTE enabled product to come out in the market is the Samsung GT-B3740 USB mobile broadband Internet stick modem. Also known as an Vodafone LTE Surfstick, this new Samsung stick modem offers the fastest uninterrupted Internet connection with download speeds of up to 100Mbps and upload speed of up to 50Mbps wherever LTE technology is available.
This means that this new stick modem is ideal for any kind of online activity, even demanding ones, such as checking and sending emails, watching and delivering webinars, conducting video conferences and query ERP/CRM applications. This Samsung GT-B3740 is also the first LTE device to be certified by the Global Certification Forum or GCF.
4G LTE Mobile WiFi Hotspot
Sierra Wireless AirCard 754S mobile hotspots support Dual-Carrier HSPA+ and LTE network technologies, letting users share a single, super-fast mobile broadband connection with up to five WiFi-enabled devices.
With its compact and lightweight design, the AirCard 754S Hotspot provides wireless access at download speeds of up to 100Mbps and upload speeds up to 50 Mbps, so customers traveling globally or at home have the ability to experience the fastest network speeds available and share and manage data with colleagues, friends or family.
Huawei E5776 is also a new LTE 4G mobile hotspot:
