Mobile communications and engineering are practically inseparable. Over the years, electronics have evolved into more efficient models that consume less power but perform better. Mobile technologies have seen several changes too, starting from wired telephones to the now modern wireless smartphones. The following are some of the significant changes:
Ultra fast Processors
Advances in chip technology directly contribute to faster processing speeds of mobile devices. Recently, significant developments have taken place in the manufacture of the silicon chip leading smaller chip size but faster speeds. For instance, Apple’s A9 processor that comes inside the iPhone 6S is considered as the fastest mobile processor at the moment. It is a 64-bit chip capable of speeds of up to 1.85 GHz and supports 2GB of RAM. On the other hand Qualcomm’s Snapdragon 820, which comes with most high-end Android devices, ranks second. These improvements in the chip technology are expected to increase in future as predicted by Moore’s law.
LTE (Long term evolution)
The LTE technology is the latest and fastest standard implemented by mobile communication. Often referred to as the 4G network, it offers seamless browsing speeds and high-quality voice transmission. The £G standard, which is the predecessor is being faced out quite rapidly across the networks in the world. Mobile telecommunication giants Verizon (a telecommunications company) sells 4G based phones, and the fast rate at which these devices are selling is a clear evidence that demand is high for better transfer speed.
There is an increasing demand for video chatting and conferencing, and this necessitates the need for a better quality mobile camera. Newer model phone cameras can now match the quality of traditional digital single-lens reflex cameras(DSLR). For example, the LG G4 smartphone comes with a 16-megapixel back camera and a front one of 8MP. The small physical size limits the phone camera, but research is underway to overcome this challenge. Linx, an Israeli camera engineering company, was recently acquired by Apple with the promise of delivering DSLR quality camera in phones. Face recognition and auto-focus are also among the changes engineering have improved in the camera
GPS (global positioning system)
The GPS system is a navigation system that is essential for everyone; from an average mobile user to complex military missions. It is based on satellite technology, and anyone with a GPS enable cell phone can easily join the network. It accurately identifies the location of the device as well as trace the location of other users on the same network. Most vehicles now come embedded with a GPS navigation system that enables the driver to locate routes and to determine the most convenient route to a certain destination.
It is evident that speed and quality are sought after when it comes to mobile communications. Communication must be done without interference in the network or slowing down of the device. Also, there is a need for better video delivery. In all these vital aspects, engineering has played a central role in ensuring that both current and future demands are met.
