Today, enterprises seek a lean setup for a new branch/office. The SD-WAN solutions available today are easy to deploy and have the ability to grow gradually based on need. SD-WAN is a technology that has evolved as a solution to address the numerous challenges related to architectures and routers. Software-defined networking is a centralized approach to network management. In SD-WAN, the Data Plane forwarding, and Control Plane are segregated to centralize the intelligence of the network. This architecture allows for centralized provisioning, monitoring, and troubleshooting, better network automation, and operations-simplification.
Enterprises like Hotels, Retail Malls, Restaurants, Cafes, etc. that have built their Guest Wi-Fi networks with MAC addresses as unique user identity will now struggle to provide a seamless experience to their guests. Using MAC reauthorization such enterprises identify and provide seamless wi-fi connections to their returning guests or even allow them to roam between multiple venues. With this new update, guests will now be forced to re-authenticate their devices via captive portal every 24 hours as their device MAC address will change. This will not only disrupt the connections of guests every day during their stay at any hotel but also returning customers will not be recognized automatically and would need to verify themselves every time they visit the venue.
The Global Database of the WBA OpenRoaming participants is also in progress to facilitate the validation of the participant organizations during the authorization of users. The framework has the potential to fill the gaps of Wi-Fi roaming challenges concerning the interconnections, security, and service assurance in visited networks and avoid the connection requests from unwanted users. By addressing the major issues in existing roaming frameworks and promoting Passpoint to steer the network selection policies, the OpenRoaming ecosystem would prove to be a pathbreaking solution in the near future.
The hype around open source solutions in the networking world is probably a decade old but the open-source history dates back to as the 1970s.

Technological advances have been instrumental in driving change in human lives and in steering the digital transformation journey of several industries. The hospitality industry is one such industry that has been reaping rich dividends by the application of technology. Right from enhancing the customer experience to streamlining front-end and back-end operations, technology is helping hospitality service providers conduct efficient resource utilization, optimize costs and improve customer experience. The introduction of over-the-top content has transformed the hospitality television landscape. Guests prefer the interactive and content-based OTT services to the linear content that was once the norm. Guestroom TVs have evolved from mere devices that help watch movies and shows to comprehensive interactive systems that entertain, inform and control guests thereby elevating the customer experience.
Mobile Edge Computing is an evolution in computer architecture, whereby computing power can be moved to the ‘edge’ of the system, to where the ‘eyes and ears’ of the system are active (Hu, 2015). Primarily used in the context of mobile cellular networks, it portends a network of mobiles, supported by a network of computing nodes, tethered close to the mobile and equipped with the ability to off-load computation needs from the mobile over high-bandwidth, low-latency wireless links (Mao, 2017). It has been argued that MEC is a natural corollary of the ‘cloudification’ of software development; the tendency of software developers to expect the scalability and on-demand resource deployment of the cloud as part of the platform (Dinh, 2013) (Othman, 2013). MEC extends this to the mobile application development arena, by providing an equivalent ‘mobile cloud’.
The hospitality industry must deal with ever-evolving customers’ tastes every single day. Major advances owing to digital innovation has enabled the market entry of brand new segments which are also performing wonderfully. What were once fledgling private accommodation and ride-hailing brands in 2009 are already at par with the Goliaths of travel.
Quite obviously, technology has brought in an unprecedented revolution as guests now demand and judge the premises based on the level of personalized experiences they get. It is no mean feat, therefore, to satisfy the trifecta of expectations that the modern customer has. This includes hyper-personalized services, seamless user experience and availability of technology that helps bridge the gap.
In the last few decades, there has been a humongous growth in the number of Internet users, devices, and connectivity-everywhere. All these factors, coupled with digital transformation across all industries globally & growing consumption of bandwidth-demanding applications, have contributed to the requirement for faster and ubiquitous wireless connectivity. To address these, the Wi-Fi Alliance- the organization responsible for conceptualizing, developing, & certifying Wi-Fi standards- announced the next generation of Wi-Fi, Wi-Fi 6. This next generation of wireless networks based on 802.11ax is a development over the current fifth generation of Wi-Fi, known as Wi-Fi 802.11ac (standardized in 2014).
Growing adoption and evolution of smartphones has had a significant impact on the sports and entertainment industries. A recent study by Cisco revealed that 57% of the fans prefer to watch sporting events at home as opposed to the real venues. At a time when millennials are leaning towards mobile and digital technology as their preferred channel for almost everything little and big, stadiums still offer something stimulating and non-replicable that can be leveraged for good – “A total fan experience”.
IT infrastructure requirements for trending applications are significantly different from those needed to support traditional applications. Application developers are re-architecting their solutions to move from monolithic architectures to microservices-based architecture. These applications, also known as Cloud-native applications, require a complete redesign of provisioning, deploying and managing strategies. This article focusses on leveraging micro-services architecture for upcoming applications, challenging requirements they pose in their provisioning/deployment/management and how latest trends in virtualization and cloud-computing space can help in resolving these requirements.

In today’s connected world, access to Wi-Fi is a necessity. Players in the hospitality industry are expected to offer Wi-Fi access to their guests during their stay at their facilities for a connected experience. There are several technology companies across the globe that are enabling digital transformation in the travel and hospitality sector with numerous offerings that help design, develop and deploy an effective WiFi services management solution.
In today’s world, guest Wi-Fi is ranked among the top desired amenity across the globe and therefore it is a critical component of the digital experience for many companies. A frictionless Wi-Fi experience is defined by various factors which play an important role in the end-user experience such as accessibility, speed, coverage, and security of the network. Though much has been done for improving the speed and coverage part, however when it comes to providing seamless guest access to Wi-Fi there is still a long way to go.
5G has an ambitious goal to increase the network capacity by 1000x, reduce network latency for URLL (ultra-reliable and low latency) applications and support ultra-dense deployments to meet IMT-2020 vision. Although it meets many of such requirements, in order to comply with all the requirements, it will still have to exploit the opportunities in the unlicensed spectrum, especially Wi-Fi.
One of the most effective ways to reach the consumer with targeted messages is to deliver it to their mobile devices. And being able to deliver it at the right time increases the effectiveness manifold. After all, would you remember to use a pharmacy discount coupon for 20% mailed to you 2 weeks ago, or would you remember to use if that coupon magically popped up when you are at CVS Pharmacy shopping?
That is the power of proximity marketing!
The Internet of Things is based on a centralized system of interrelated devices that are equipped with computing abilities. These devices have inbuilt UIDs, a set of unique identifiers that can transfer data through a network without requiring human interaction. The sensors in devices and appliances will collect different types of data and communicate, analyze or even act on it. With IoT, businesses can develop new ways to connect and increase value by building new businesses and channels of revenue. It is no secret that implementing solutions that involve the use of the IoT would provide seamless connectivity across all platforms, but at the same time, there’s a raging security issue that risks shutting down the entire set up.
The world has come to a point where automation is not a fancy word anymore. Often, automation can bring visuals of robots in your mind. However, look around, and you will find plenty of automatic devices that you use every single day. In fact, many of the things your smartphone does are automatic as well. For example, once you have the Wi-Fi option on, it connects to an available network automatically. A simple example like this shows how beneficial automation can be. Apply the same concept to buildings, and the benefits increase by manifolds.
Software defined networking (SDN) is one of the key technologies driving the transformation of the next generation networks. To begin with, SDN was just a mechanism to “separate out control from data”. The logic to control the network was moved to a centralized controller. This allowed the operators to program the network on demand, from one point of control. Further, it allowed them to set rules/configurations across devices, from different vendors in a unified way, without manual intervention. These flexibilities proved to be a huge improvement over traditional networking where provisioning/configuration was done on individual basis and a single failure in the network could lead to huge downtimes. The notion and scope of SDN applicability in networks has considerably transformed since then. Traditional networking using distributed routing protocols are focussed on the needs of the basic network; route discovery, link failure recovery, etc. However, these services by themselves don’t fulfil the requirements of emerging technologies like IoT and MEC – handling multi-vendor devices, heterogenous networks (Wi-Fi, Bluetooth, ZigBee, LTE), huge amount of data, faster deployments, management of services etc. SDN promises to deliver an agile and flexible network infrastructure, to handle varying user-demands and diverse network scenarios.
Communication technology has been evolving at a fast pace for past two decades. During this time, wireless technology has also gone through many changes. From 3G and 4G, now we have companies expecting and preparing for 5G wireless technology. It’s the fifth-generation technology that might not have arrived yet, but OEMs have already started to make 5G enabled equipment.
There is a dire need for quality Wi-Fi services, all over the world. As wireless technology continues to escalate, an estimated 200 billion wireless devices will be operational by 2020. In addition to that, carrier Wi-Fi hotspots are likely to reach 13.3 million by the same year. Both businesses and individuals are searching for secure and reliable wireless internet access. The quality of Wi-Fi service will have to conquer many challenges as the major focus shift towards of Internet of Things.
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 inclusive and constantly evolving cloud computing platform, Amazon Web Services (AWS), is another milestone achieved by the retail giant. Web services, popularly termed as cloud computing services, are facilitating millions of users across the globe. The first AWS offerings surfaced in 2006 and offered online services for client-side applications and websites. Amazon Web Service was initially nothing but the company’s backend technology.
Cloud computing will soon be a norm for hosting software applications catering to a variety of use-cases in different verticals. Cloud Computing refers to Internet-based services that provide access to managed IT resources; these resources are managed by experts and are available on-demand on a pay-per-use model. This enables the application developers to focus on the use-case and come up with an MVP (minimum viable product) in a shorter period.
