General Specification / FAQ
SignalViewer General Specifications
Design Keys of SignalViewer are based on:
- • Simple but smart and very efficient tool
- • Working on top level, “Integrate variety tools that working independently”
- • Integrated data for fast important decision
- • Customer Experience Oriented
- • Used by all stakeholders
SignalViewer General Technical Specification
- • Available for any mobile technologies (GSM900/1800,3G, HSPA, LTE), and various mobile operating system (iOS, Android, RIM, Symbian and Microsoft Mobile)
- • Evaluate any call events (Voice call, text messaging, MMS, USSD and Data test) run by the users
- • Engineering test scenario can be run manually from the handset or remotely scheduled from the server. This feature will allow direct verification of the reported complaints and allow operator to verify any major changes (e.g. SW upgrade) without any territory/ boundary limitation
- • Data Sent via data application
- • Support OTA installation
What is 4G ?
4G stands for the fourth generation of mobile connection speeds, and is the first to bring broadband internet to the smartphone without being connected to Wi-Fi. 4G has a strict technical definition (see our ‘What is LTE?’ section) but essentially it makes use of different spectrum frequencies to either 2G or 3G and uses this new spectrum band to bring much faster cellular data speeds to cell phones. Data shared with us by users of the SignalViewer app for Android and iOS shows that, at the beginning of 2013, average global 4G LTE speeds were 10.4 Mbps while average 3G speeds were only 1.5Mbps. Our research therefore suggests that 4G LTE is currently seven times faster than 3G speeds.
What is 3G ?
3G stands for the third generation of mobile connection technology, and is the second (after 2G) to support data as well as voice and SMS. 3G was first rolled-out in the USA by Verizon in 2002 and currently (as of 2013) is used as the primary data network by most smartphones globally. The average 3G speed globally (according to data shared with us by the users of our app for Android and iOS) is 1.5Mbps, which represented a huge step forward in comparison to 2G which currently averages 0.3Mbps. The data speeds made possible by 3G facilitated the mobile-optimised Internet, allowing for fast browsing from a mobile device on the move. 3G is in the process of being superseded by 4G LTE, which offers even faster speeds without the need for a fixed connection.
What is LTE ?
LTE (often labelled 4G for marketing purposes) stands for Long Term Evolution and is a form of cellular wireless connection that represents a significant upgrade to 3G in terms of data speeds. The technical definition of ‘true’ 4G is that it should have data speeds capable of reaching 100Mbp/s while on moving transport and 1Gbp/s when stationary. While LTE is much faster than 3G, it has yet to reach the International Telecoms Union’s (ITU) technical definition of 4G. LTE does represent a generational shift in cellular network speeds, but is labelled ‘evolution’ to show that the process is yet to be fully completed.
How to check your Internet speed
There are few things more frustrating than having slow internet or a poor connection, especially if you’re wanting to do something that involves using a lot of data (like watching a film online). Internet speeds are not constant, so a connection that works well in the morning may be considerably slower in the afternoon. To check how your connection is running in real time, download the free SignalViewer app for Android and iOS and use the ‘speedtest’ feature to see how fast your wifi or cellular connection is running.
The Difference between a Megabyte (MB) and a Megabit (Mb)
One thing that often gives people confusion is the difference between a Megabyte (used for file size) and a Megabit (used for download speeds). People often assume that a download speed of 1 Megabit per second (1 Mbps) will allow them to download a 1 Megabyte file in one second. This is not the case, a Megabit is 1/8 as big as a Megabyte, meaning that to download a 1MB file in 1 second you would need a connection of 8Mbps. The difference between a Gigabyte (GB) and a Gigabit (Gb) is the same, with a Gigabyte being 8 times larger than a Gigabit. To calculate how long it will take a file to download over your connection, you can use Google’s simple MB/Mb converter.
