Mushrooming Mobile Wallets and Payment Applications

Mushrooming Mobile Wallets and Payment Applications

First, plastic money replaced physical money. And now, digital money has taken over the role of the plastic credit and debit cards. We are talking about mobile wallets and payment solutions that have replaced the way we were handling electronic financial transactions. Though companies like PayTM and MobiKwik have been around for a few years now, they have recently become popular. Applications such as Momo and Ultracash have partnered with mobile wallets to help users to pay easily using their mobile phones at various partner places such as restaurants, malls and cinema multiplexes. These applications provide the option of registering credit cards, debit cards for payment to various merchants. These applications also provide net banking as an option for payment. Recently, many merchants – even local grocery shops – allow users to pay through these applications. All parties in the ecosystem that includes merchants, mobile wallets, and application vendors are providing attractive offers in the form of discounts and cashback to promote usage of these applications. How it works:...

Narrowband-IOT: Enabling ultra-low cost IoT devices over cellular wireless

Narrowband-IOT: Enabling ultra-low cost IoT devices over cellular wireless

Cellular wireless communication is on the threshold of its 5th generation of evolution. From diverse region-specific standards in its 1st generation during the late 1970’s, the industry across the world has come together under the aegis of 3GPP for LTE as a unified 4th generation standard adopted today. The focus of services offered has evolved from being voice centric to pure packet data where voice is also offered over a packet network in VoLTE. With increasing relevance of Machine-to-Machine (M2M) communication enabling the Internet of Things (IoT), 3GPP has recognized the need to enable ultra-low cost wireless devices serviced by ubiquitous cellular networks. The result is Narrowband-IoT (NB-IoT), a variant of LTE technology that is being specified in Release 13 of 3GPP. LTE has been optimized for high bandwidth performance, during its evolution, till Release 12 of 3GPP specifications. Devices with capability ranging from 1 Mbps up to 450 Mbps of data throughput are supported but overheads are high for devices which should handle low data rates. Notable is the need for...

M2M Devices: Cellular Modem Optimizations

M2M Devices: Cellular Modem Optimizations

M2M devices are devices which communicate with other devices or servers, without the need for human interaction. These kinds of devices are used in many application areas such as industrial automation, smart cities, health, etc. These devices are to be networked within a premise (intranet) or over the internet. Within intranet, these devices can communicate over short range connectivity technologies such as WiFi, Zigbee, and Bluetooth. These devices have to connect with the internet using WiFi or cellular. WiFi may not always be an option because of lack of access points at all places, especially outdoor premises. In cases where Wi-Fi is not suitable, cellular effectively provides the last-mile connectivity. Traditional cellular connectivity has been used in high-end devices like smartphones, tablets, laptops and netbooks. For this, cellular modems have evolved mainly to handle many scenarios such as seamless mobility and high data rates. Since M2M devices need to be low footprint and less power consumption, there is a need for customizing cellular modems. Here are a few insights to possible...

Google is spreading its wings

Google is spreading its wings

Google never envisioned itself as ’just another’ search engine company when other search engines like Altavista, Yahoo, WebCrawler, AskJeeves and Infoseek already existed. It had different plans. Search engines earned revenue through advertisements which were clicked by its users more often. So, these search engine companies tried attracting more and more users to their platform. But Google’s innovative methods of getting user’s attention started with their PageRank, Adwords and MobAd technologies. With Google’s ability to sense user expectations, and define user needs, they continued to grab users through Android-based devices, starting with handsets and expanding to other domains such as consumer electronics, wearable and automotive. All these innovative methods helped Google to become one the most well-known companies from just another search engine. What makes Google revenue roadmap different? They are doing this for what? The answer is content – creating, hosting and carriage – (Creation through devices, hosting through projects such as YouTube and Google+ and carriage through fiber/wireless). Google decisions have always been driven towards encouraging users...

Google Enters Wireless Services – More avenues for ads?

Google Enters Wireless Services – More avenues for ads?

Google is getting into the business of becoming a network carrier to start selling wireless services to customers. Business Week has reported as recently as last week that Google has reached an agreement with Sprint Corp. to use its network and operate as an MVNO (Mobile Virtual Network Operator). How does it benefit Google? Before we try to understand this, let’s examine if this is an unusual step. Going by history, exploration into uncharted territories is nothing new to Google and this isn’t the first time they are entering into communications infrastructure business. Google is already providing internet services through their Google Fiber initiative. Not to forget their other giant and ambitious initiatives like Project Loon and Self-Driving Car. Coming back to the subject, some possible reasons why Google is doing this: To demonstrate stock Android’s adequacy for present market and the unnecessary medium to high amount of customizations that network operators demand. The line of Nexus devices is time and again substantiating this wherein OEMs are already shedding...

A look at some Spectrum – Part 1

A look at some Spectrum – Part 1

Spectrum or electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The spectrum is divided into ranges of frequencies called chunks suitable for different purposes like mobile communication, TV broadcasting, radio, etc. The definition of ranges of frequencies & allocation is carried out by ITU-T.  This blog explains about the spectrum space and spectrum bands. Spectrum allocation policy for different usages is defined per region. Spectrum bands allocation for different purposes in US is available in the chart linked below. http://www.ntia.doc.gov/files/ntia/publications/spectrum_wall_chart_aug2011.pdf There are three regions defined by ITU-T, and countries fall in any one region. Region 1 : Europe, Middle East, Africa, Countries belonging to former Soviet Union, Mongolia and Siberia Region 2: North and South America Region 3: Asia and Australia Spectrum space is controlled by respective Governments, through some Authoritative body. In US, it is FCC and NTIA and in India it is Wireless Planning & Co-ordination wing along with TRAI. Spectrum bands are licensed through allocation/auction by respective Governments. In addition, Government may...
