TRAI plans Nationwide WiFi hotspot network

trai_big1

TRAI, Telecom regulatory body of India, has invited businesses both small and big to become part of Pilot of what it calls PDO (Public Data Office), Network. PDO is essentially WiFi hotspot, but these will part of a wider network which will take care of authentication and payment, this will allow users to make single payment and authentication to use a network of WiFi hotspots.

Regulator has devised a framework under which these PDOs will operate, it is called WiFi Access Network Interface (WANI). This interface will allow business to easily setup public WiFi hotspots without bothering about setting up payment and authentication systems and allow users one click payment and authentication and usage of one or more hotspot in a single session.

TRAI wants prices to be available in small sachet of Rs 2 to Rs 20 per session, it also wants the Public Wi-Fi Hotspots to store community interest data locally, and allow access to it through negligible costs.

In this WiFi Hotspot Network three entities will be involved, first being Public Data Office Provider/Aggregator, it will provide one or more WiFi hotspots to the public on free or paid model, second will be App provider whose role will be to manage user’s KYC (mobile or Aadhaar) backed profile, allow all digital payment methods, and allow users to easily connect to hotspots. and Third and final part will be played by Hardware, software and service provider they will form the back end of the network.

TRAI will release WANI technology Architecture Document in next couple of days for the entities which wants to participate in the Pilot project.

TRAI has said “This Pilot aims to demonstrate that un-bundling of services reduces rework, speeds up development and hence is the most effective way to tackle this complex problem”.

It goes on to add “PDOs will be akin to the PCOs that connected all of India, even when tele-density was less than 7 telephones per 100 people. It is also suggested that the Public Wi-Fi Hotspots store community interest data locally, and allow access to it through negligible costs. Overall, these suggestions encourage the PDOs to become bustling centers of economic activity, where consumption of data for the average Indian becomes as common as consuming a cup of hot chai”.

Plasma Antennas Joins Small Cell Forum On Commercial 5G

plasma-antennas

Plasma Antennas, the inventors of plasma silicon technology, today announced that it has joined Small Cell Forum (SCF), the global industry body driving the wide-scale adoption of small cells and heterogeneous networks.

The new generation of 5G cellular networks will provide massive, instantly steerable bandwidth in mmWave frequencies, and will rely on a much denser network topology, where small cells will play a major part. But the drive to making 5G a commercial reality is being held back by today’s phased array antennas.

Once considered state of the art, phased array technology does not provide the required range and has not developed to the point that it makes a commercial mmWave 5G service viable. These shortcomings are exacerbated when miniaturising base stations into small cells.

Plasma Antennas has solved the 5G antenna challenge, and unlocked the 5G small cell potential at the same time. Proven for the UK defence industry, Plasma Antennas’ patented plasma beam-forming technology is a market-defining innovation for mmWave applications; transforming performance, costs and simplicity. It has very low loss, low power consumption, no moving parts, no power limits, it can switch direction in just a few hundred nanoseconds and costs a fraction of phased array technology.

Small Cell Forum supports, promotes and helps drive the development and adoption of small cell technologies to improve the coverage, capacity and services delivered by mobile networks.

By promoting their use in operator networks, the ever-increasing consumer requirement for using mobile devices wherever we are, with ubiquitous coverage and an uninterrupted service, can become a reality. In 5G, URLLC (Ultra Reliable Low Latency Communications) over mmWave links present particular challenges. Innovation will be required to meet the cost and performance goals that will make 5G attractive, usable and affordable.

“As the industry moves towards the 5G era, small cells have been accepted as critical in building out next generation networks, and antenna technology is a core component in making this a practical reality,” said David Orloff, Chair of Small Cell Forum. “We are delighted to welcome Plasma Antennas to the Forum and look forward to their involvement and input.”

Paul Phillipson, CEO of Plasma Antennas, said “I come from a background of Small Cell technology with Ubiquisys, ipaccess and Lucent. I have known for a long time that Small Cells are the answer to coverage and performance. 5G presents challenges that demand innovation and new approaches. Plasma Antennas bring niche defence and security technology which elegantly switches sector and scales to deliver significant cost and performance advantages in mass market telecoms at mmWave frequencies.”

Unlicensed Broadband Radios And The Market Dynamics

unlicensed spectrum band

 

With the rising adoption of smartphones in India and subsequent consumption of data on these devices, the country stares at a herculean task of providing high speed quality service to its consumers. The future of mobile broadband, solely based on currently allocated licensed spectrum, looks bleak. Utilising the potential of unlicensed spectrum holds the key here.

All wireless communication technologies require some kind of airwaves to send and receive data, however not all airwave bands are licensed, thus allowing the operator and others to deploy equipment in such spectrum without having to go through regulatory approvals and pay any license fee for its usage.

In India, among the available unlicensed spectrum bands, the Wireless Planning and Coordination wing (WPC) of Indian government under the ministry of telecom has notified 5.825-5.875 GHz band for outdoor use. However, industry bodies have consistently been demanding the government to release more unlicensed spectrum bands to enable bigger data network deployments offering higher capacities, as the currently available spectrum is too low to enable the Digital India Initiatives or reach the rural hinterland in a cost effective manner.

The Use Case

As broadband becomes ubiquitous and demands rise to be always-connected, telecom service providers go the extra mile to provide their users the best possible experience. Earlier the demand to remain connected was the preserve of some enterprises but with the Indian Government’s Digital India Programme to ensure that Government services are made available to citizens electronically by improved online infrastructure and by increasing Internet connectivity or by making the country digitally empowered in the field of technology, using available wireless technologies has become critical for service providers. Indian government’s ambitious project Bharat Net or NOFN also looks a using the unlicensed airwaves to complement the existing fibre network. These airwaves come handy, particularly, in cases like difficult and hilly terrains, where it becomes difficult to lay fibre.

Wi-Fi hotspots in commercial as well as urban areas to cater to the ever increasing data requirements requires unlicensed spectrum and related equipments or UBRs, as it is difficult for telecom operators and ISPs to deploy more cellular infrastructure due to cost and spectrum resources.

Smart Cities project is one more area where unlicensed spectrum are expected to see demand. A smart city, will be based on the success of internet of things (IOT) as multiple components like utilities, smart parking, lighting, surveillance etc will be done automatically through the help of thousands of sensors. A robust network architecture is required to connect all building blocks of a smart city; and it just can’t solely rely on cellular or 4G network as in emergency situations these tend to be jammed. Backhaul through small cells will form the backbone of the network.

Equipments and radios that work on these unlicensed spectrum bands are called UBRs or unlicensed broadband radios.

Benefits of UBR

Broadband Radio units offer reliable, high-speed and secure wireless connectivity between multiple remote locations through high-capacity wireless point to point and point to multipoint configurations. Radios based on sub 6GHz bands can cover long distance and are also suitable for urban deployments providing non line of sight capabilities. Some vendors provide carrier grade performance with a high data rate which is both stable & reliable. As these radios work in unlicensed spectrum bands, they need to conform to regulatory requirements of governments; In India it is WPC, part of DOT which is responsible for the regulation.

Besides, having smaller footprints to conventional microwave radios, they are easy to deploy and mostly operate on plug & play model. The radios, in most cases, can be deployed within hours and, if required, can be dismantled easily and be redeployed somewhere else with no or little tweaks in the configuration.

The UBRs are being used by government agencies and enterprises for connecting multiple locations with head offices within a secured environment both in private network mode as well as extension of large VPN networks. ISPs and carriers use UBRs to offer high-speed wireless broadband access to their customers where it is not feasible to lay fibre. It is perhaps the most cost effective last mile access technology for broadband.

Challenges

Like licensed spectrum, the use of unlicensed airwaves do have their own challenges, the biggest of which is interference. While government policies regulate the unlicensed band, the solution, however, remains with the selection of right kind of RF technology and the reliability and scalability of the network architecture.

Vendors In Fray

There are multiple global vendors offering different products and solutions for the unlicensed airwaves. Among the international companies who present in India with products in the unlicensed bands are Airspan, Alvarion, Cambium Proxim, Radwin and Ubiquity, with HQs  in China, Russia, Israel & United States. There are a handful of Indian companies also viz. Primatel, Maksat and Vihaan Networks offering products in these spectrum.

These technology firms offer different technologies serving different requirements in this arena, from low distance low throughput commercial to high throughput, high SLA enterprise and surveillance requirements, with prices offered based on these matrices.

The requirement of telecom operators for their customers and infrastructure, are generally for high capacity, interference mitigation, high reliability & high MTBF equipment which also provides low operating costs. To fulfill the same, they follow stringent criterion for selection and rely on thorough testing of the equipment before selection.

Snapshot of each of these players in India in the unlicensed bands is provided for the reader’s reference.
