Network slicing is a type of virtual network architecture that allows various networks to be created on top of a mutually shared physical infrastructure. These virtual networks are then personalized to meet the particular needs and demands of devices, applications, services, operators or customers. It uses the same principles as those behind network functions virtualization (NFV) and software defined networking (SDN). The greater flexibility brought out by network slicing will help address the efficiency, cost, and versatility requirements levied by the future.
An infrastructure where processing and data storage takes place outside mobile devices can be referred to as a ‘mobile cloud’. By utilizing the computing and storage capabilities of the mobile cloud, computer applications can run on low resource mobile devices.

The 5th generation of networks is going to be built around the seamless integration of multiple different types of radio technologies; LTE, LTE-U, WLAN. Operators want to deploy a combination of different network infrastructure and then use the most appropriate among what is available to provide … read more
The progress from initial 2G and 3G networks to mobile broadband technology has changed the entire dynamics of our society and the business industry. If 5G becomes a reality, you can expect even greater levels of transformation. A good number of engineering R&D services companies have made considerable inroads into 5G application development.
Wi-Fi as a technology is nearing two decades and the Wi-Fi alliance itself is 15 years old. With the ubiquity of smartphones, Wi-Fi has made impressive strides as the transmission technology of choice for Internet data; it is reported that fully 40% of Internet mobile traffic is carried on Wi-Fi … read more
The case for mmWave in 5G networks is rather strong (Rappaport, Sun, et al. 2013). Given the continuous demand for spectrum and the recent progresses in mmIC fabrication technology, we can reasonably expect to see mmWave migrate from the existing point to point backhaul links … read more
The 5th generation cellular networks have set an explicit target to improve the performance of cell-edge users. This is widely acknowledged in the industry as being a challenge; multiple studies [ (1), (2)] have modelled cell-edge channels and UE performance in representative … read more
Positioning is the process of determining the geographical location of a device such as a mobile phone, laptop or tablet computer, a personal digital assistant (PDA), or navigation or tracking equipment. Positioning technologies are gaining importance every day in mobile systems, demanding … read more
Cellular networks have seen continuous growth in size and complexity over the last few years. This growth can be attributed to multiple factors; the explosion of content being delivered via the internet, the explosion of social media, the growing … read more
Radio access technology has changed the way we go about our business, both at work and at play. With increasing demands to stay connected, we cannot rely on just one type of technology to keep us online. The good news is, today’s wireless environment is possible because multiple radio access technologies can co-exist, many working seamlessly on a single device. With all of these technologies working simultaneously, there are some challenges presented by the ever-changing world of wireless technology. The development of new connected devices, new types of RATs, and increasing demand for data means that we’re nowhere near the end of this evolution. HSC is committed to staying on top of industry trends, standards, and progress in the wireless technology development industry. To help explain the current state of radio access technology, as well as where it looks like things are headed, we’ve created an infographic that illustrates the co-existence of multiple radio access technologies as it stands today. Check it out below!
Cellular wireless technology moved from the 3rd generation (3G) to the 4thgeneration (4G) with the release of the LTE standards. One of the fundamental changes brought by this technology was the use of Orthogonal Frequency … read more
It’s truly an exciting time to watch the landscape of wireless technology expand. As the demand for wireless connectivity continues to increase, this demand is pushing the capacity and efficiency of wireless technologies to their limits. There is, however, a light at the end of the tunnel.
ANDSF, which stands for access network discovery and selection function, is an entity within the EPC (evolved packet core) with the purpose of assisting UEs in the discovery/selection of access networks, such as WiFi, WiMax, and LTE, in their vicinity; providing them with rules policing the connection to these networks.
An introductory article on the different technologies emerging in the wireless space can feel like an introductory article how to speak a foreign language. For some, the language makes sense; they’ve been around it, taken a couple classes and maybe even traveled to a place where that’s the only language spoken. For others, it can be intimidating the first few times you hear the words and phrases.
Wireless technology is ever-evolving, and there’s no end in sight. But where did it all begin? How did we get to where we are now? We’ve put together an infographic illustrating the transformations of wireless technologies from 1G in the 80s to the latest developments, to projections of connectivity in 2020. It’s been quite a journey, with many steps along the way – check it out!
The future of wireless technology is bright…and crowded. As more of the population connects through mobile phones, smart watches, tablets, and the many other wireless devices available, the competition for access to WiFi and cellular networks is increasing faster than ever before. We’ve already touched on how offloading, small cell technology and nodes help alleviate some of the traffic in previous posts. But believe it or not there’s more to the equation.
Your grandfather probably remembers a time when men’s razors had just one blade. It was sharp and it got the job done…but with some scrapes and cuts along the way. Saturday Night Live famously mocked the addition of more razors saying “the 6th blade gently removes the 1stlayer of skin.” But all mocking aside, this is the age of more. In a world of innovation from analog to digital to 3G and to 4G, the next logical progression is a 5G network. Innovation, however, does not always care about logic or what makes sense. It made sense for Apple to develop their own mapping applications right? The buzz surrounding a 5G mobile network is real, but the question is, is it something to get excited about?
With the advent of IP capable smart devices e.g. mobile phones, tablets etc. and easy internet access, there has been an exponential growth in data traffic. Cellular network operators have been trying to cope up with this ‘tsunami’ of data traffic by adopting new technological innovations like … read more
If we track the evolution of wireless technologies, cooperation (as a way of improving network capacity and performance) stands out as one of the key movers of this evolution.
Wi-Fi Direct is a new technology defined by the Wi-Fi Alliance wherein capable devices can connect directly to each other quickly, securely and conveniently to do tasks such as printing, synchronization, and sharing of data. In this article we provide a thorough overview of the functionalities … read more
Wireless LAN technology is an indispensable part of the enterprise network. As the network increases, managing tens of thousands of Access Points (APs) becomes an issue. This leads to the requirement of self-configuring, self-managing and self healing networks. SON (Self optimizing networks) is … read more
