Communications RELOADED-2020

>>

Many of you might be wondering that what the heck! this IoT(Internet Of Things) is?? This topic has gained so much importance in today's connected world and have also become so complex that its gonna be a part of ours daily life in the near future with over 50 billion connected devices by 2020. In simple terms, IoT is a kind of communication between different sorts of object like your alarm-clock, coffee-maker, toaster, washing-machine, plant-pot, cars, etc which are connected to the Internet and able collect and exchange data. 

Now lets take the above example that your alarm clock wakes you up in the morning and give notification to the coffee maker and toaster to make your coffee and toast the bread. Then suddenly when you are heading towards your work you may get message from your plant pot, "I am thirsty. Give me some water". This is what IoT is all about, everything connected to each other.

The best part of IoT is that its not only a communication between humans and machines but also between machines itself which can be achieved through AI(Artificial Intelligence). So, till now we talking about connected objects and devices but how are they connected and how they communicate to each other???

For this we need some hardware boards like Arduino Uno and Raspberry Pi. We keep on integrating different boards and attach many sensors(like the one in the plant pot to sense the the humidity percentage in sand) and then program them to achieve a whole connected network infrastructure.
  
Currently, the tech giant IBM has introduced the Watson Iot Platform which can connect, manage, analyze and secure IoT devices and data using cognitive APIs, Weather Company data, block-chain and more which will take Iot to the next level by transforming the way business works using data, cognitive computing and Watson IoT Platform.

5th Generation mobile Networks

The era of whole new networking standards are coming soon (by 2020) and this is what we all are eagerly waiting for. That's why big tech companies like Nokia, Samsung, Ericsson, Qualcomm, are working so vigorously on implementing them. 5G is the next generation mobile wireless standard based on the IEEE 802.11ac standard of broadband technology but its not the evolution of 4G, its a full new mobile system.

Hubert Da Costa, Vice President, EMEA at Cradlepoint said: "5G Wi-Fi connections are set to be about three times faster than 4G, starting with 450Mbps(56MBps) in single-stream, 900 Mbps(112MBps) (dual- stream) and 1.3Gbps (three-stream). So, whilst we are already starting to see a huge growth in IoT and smart devices, 5G's speed and capacity will enable an even more rapid arrival of this connected future."

But as we know everything has pros and cons, so  with the addition of 5G to the wireless spectrum we might be at risk of overcrowding the frequency range which can be harmful and if we talk about pros we have,

• new wireless technology, to support dense deployment of high-speed low-latency services;
• improved utilization of current frequency bands (up to 6GHz) and exploitation of new frequencies in the centimeter/millimeter wave bands (somewhere between 6GHz and 100GHz), to deliver the necessary capacity and coverage;
• novel techniques for radio resource control, antennas, protocols and architecture, to improve spectrum utilization, reduce latency and increase flexibility.
• context aware mapping of services to technologies.

"Current 4G mobile standards have the potential to provide 100s of Mbps. 5G offers to take that into multi-gigabits per second, giving rise to the ‘Gigabit Smart-phone’ and hopefully a slew of innovative services and applications that truly need the type of connectivity that only 5G can offer," says Paul Gainham, senior director, SP Marketing EMEA at Juniper Networks.

Now 5G beta handsets are already being created and field tested by Ericsson and Nokia and we will soon get hands on it in the next few years.
