What is Wireless network and its types

Wireless network and It’s Types Available in India

As the name suggest itself wireless network is network of connected computers or mobile devices without wire.

Ambiguity and extension of one month for new Broadcasting Regulations by TRAI

How Wireless Network is created?

To create wireless network , access points are to be installed which can be connected by Laptops , mobiles and other wireless devices, thus making a wireless network.

Wireless Internet

When access points for wireless network are connected to Internet or Wide area network all the device connected with the access points are connected to Internet Service.

Difference between Wireless Internet service and Mobile Internet service

While it seems as there is no difference in Wireless Internet service and mobile internet service But Wireless Internet service has limitation that it is available upto certain range , while Mobile internet can be accessed anywhere with availability of mobile network.

Mobile internet services are not standalone services as voice services are provided along with internet while wireless internet service provides Internet service alone.

Types of Wireless Internet Services

Hotspots, and Wi-Fi broadband are the wireless Internet services while 3G & 4G provides mobile Internet services. 

Wireless Internet Service providers

Telecom operators AIRTEL and BSNL provides wireless internet services. BSNL provides wireless internet services using HotSpots and Broadband Wi-fi.

Bharat Sanchar Nigam Limited has already installed more than 15000 public wi-fi hotspots at famous tourist places and important places.

BSNL also provides Wi-fi broadband in all major cities. This wi-fi broadband service of BSNL is having very good download and upload speeds and can cover upto 5 km of distance from BSNL exchange.

Google’s project Loon for Wireless Internet

In 2016 Google was allowed to test its Project loon in India to provide wireless Internet. Project loon is a project of Google to provide internet services using floating balloons at 20 Km height in stratosphere above earth. Using these balloons Google can provide transmission of internet service. This project is already tested in New Zealand, California and Brazil.

Google was demanding spectrum in 700 Mhz to test this project but Government rejected this request and suggested to partner with telecom operators. While Google was in talks with Government Owned BSNL for Spectrum sharing ,this project could not be kick started in the need of permission from DGCA citing security reasons and no clear policy.

According to project loon website the life of such balloons is 190 days and data transfer can take place between two balloons upto distance of 100 km making network of these balloons and bu connecting them to service provider on the earth these balloons can provide wireless internet speed upto 10 Mbps to the consumers.
 This project is of great importance for far-flung areas where providing and maintaining  Internet services is really difficult.

Ambiguity and extension of one month for new Broadcasting Regulations by TRAI

Extension of one month for new Broadcasting Regulations by TRAI

As new boadcasting regulations issued by TRAI were to be implemented from today 29-12-2018 , cable operators in various parts of India opposed the decision by TV blackout.

Keeping the confusion among distributors and consumers TRAI extended due date for migration to new regime for one month upto 31st January 2019.

What is the problem with new Regulations

Important points in TRAI's new broadcasting regulations , are :

1). Distributers has to charge Rs. 130 only for 100 free to air channels and it is compulsory to show these free to air channels.

2). consumer can subscribe for additional channels in slabs  of 25 channels per slab ,with charge of 20 Rs /slab

3). Consumer can pay for paid channels  in form of bouquets made by Broadcasters as-well-as by the distributors.

Now there is great confusion in the minds of consumer as well as distributor about how charges to be paid for watching channels of their choice . If consumer selects 3-4 paid channels he has to pay 20 Rs . addtional to distributor & take one slab of 25 channels .Additional  charges required to be paid to  broadcaster by consumer .Every broadcaster have their own bucket of channels like sony has sixer pack at Rs. 39 and sixer HD pack at Rs 59 . So consumer has to take one bucket from broadcaster to see 2 or three channels of his choice.For paid channels from different distributor consumer has to select different boquet made by different broadcaster.

It is also being said same charges to be paid for every additional TV set used in single house .

Things are not very clear , so TRAI has extended due date to implement new guidelines upto 31st January 2019 .Let see how long it takes to make things crystal clear . 

No tarriff details for Tv briadcasting using android Apps

While TRAI has fixed capacity charges for cable operators at Rs 130 for showing 100 free channels no such guidelines issued for TV broadcasters using Android apps like AIRTEL TV, JIO TV. Any rise in monthly charge for waching channels through DTH or cable operator will be boon for APP based broadcasters like AIRTEL, JIOTV, Netflix, AMAZON PRIME .

When 5G wireless network will be released in India

When 5G wireless network will be released in India

Although news on 5G  network trials worldwide is common these days. Present Government in India has pledged that India will not lag behind in launching 5G services and expected to start in 2020. But honestly common man may not soon get real 5G network .The reasons for it are obvious looking at history and pace of technological change  in India.

5G network  in India

Fierce competition in Telecom Sector and Huge Debt

It is to be noted that telecom services in India are cheapest in the world leaving very less margin for the operators to earn. Telecom operators are already under debt burden of more than 7 lakh crores.
While 5G network infrastructure needs huge investment ,how operators will repay their existing debt  in such market conditions is a big question.

Small Coverage area of 5G

5G wireless technology uses high frequencies in the 20-50 Ghz band thus coverage of such BTS will be one tenth of present 3G or 4G towers working in 2100 Mhz and 1/20th to 2G and 4G working in 800 and 900 Mhz band. To ensure proper coverage operators will be required further investment in the construction of tower ,along with upgrading existing mobile towers.

Costly 5G Devices

4G was first launched in 2012 by AIRTEL. It took 4-5 years till  late 2016 when common man experienced 4G services with cheap devices provided by RJIO. Still services offered by telecom operators in the name of 4G are not upto the 4G standars.While 4G  boast of 100-300 Mbps speeds , max speed experienced by users is below 25 Mbps. To give 5G services operators has to launch chep 5G devices bundled with monthly plans to make this technology accessible to common man .

Limitation of OFC media in cities

Although most of the telecom operators are having there ofc media for providing data bandwidth to mobile towers, still number of such towers are working on microwave links these towers needs to be connected with the optical fiber to provide bandwidth of 1 Gbps or more . While it seems quite easy but not the reality.
In cities which are already developed giving fiber to every tower require laying of fiber ,crossing of roads .In cities already Gutter line, pipelines , Electricity line are laid underground.Laying of fibers to every society or colony may cause damage to damage to these services . While cable operators uses electricity poles ,trees and rooftops without permission for overhead lines it can't be telecom operators. 

Scrapping of Old tower Equipments

While implementing new technology operators have extra burden of handling old equipments till all the customer migrate to new technology.

While GSM technology has lasted nearly 18 years  and will be in use for few more years ,3G is going to be scrapped as its spectrum is being used by old operators to provide 4G services . All operators are facing shortage of 4G spectrum , scrapping 3G is only solution to avoid further investment in Spectrum purchase. Customers using 3G needs to be migrated in 4G or customers are required to replace their devices.

Deficit of Rural infrastructure

While operators are planning for 5G services their main focus is on big cities from where they can generate sufficient revenue. While rural area is concern there is no sufficient infra and revenue generation where any opearator can bet on investment. While government is subsidising wi-Fi hotspot in rural areas this is limited to rural exchanges of BSNL with coverage of mere 100 meters and bandwidh of 2Mbps. Thus providing 5G services without interruption across the nation is day's dream.

What can be done by Government 

While it is a matter of debate that what Govenment can do to ensure that customers could not be cheated in the name 5G few suggestions are:

1. In cities state government should be involved  and common duct can be made by R&B across the roads and along the roads which can be utilised by all the operators for laying of fibers, for that operators could be charged.This will reduce the expenditure of operators. Alongwith 5G network require tower situated like streetlights situated in the divider , which is not possible without government's support.

2. Operators should be allotted spectrum in affordable price so that they could invest more in infrastructure to provide seamless services.

3. Services in rural areas to be subsidised  or hotspot with coverage of minimum 1 km should be installed with sufficient bandwidth.A sit is not possible to invest heavily in rural areas without revenue generation.

Although all the operators including Government owned BSNL are working with tehnological giants like, Nokia, Erricson,  etc to create environment for 5G services , Indian people may see mere upgrade of 4G or 4G+ in the name of 5G network without proper support from Government of India.  It is said that 5G wireless network will provide data speeds in 1-100 Gbps, while in India 4G could not touch 100 Mbps even after 2 years of service launch . Meanwhile AIRTEL have tested 500 Mbps speed during testing LAA technology recently but it yet to be implemented nationwide.

Airtel-Ericsson 4G Trial Hits 500 Mbps Download Speed on Smartphones using LAA over LTE network


Recently AIRTEL tested a new technology Licensed Assisted Access (LAA) with technology partner Erricson on its active LTE (4G) network to test speed upto 500 Mbps ,near tower and upto 400 Mbps at a distance of 180 Mtr. This can be seen as prepatory work for 5G by the Telecom Giant.

As per Nitin Bansal, Head of Network Solutions, South East Asia, Oceania and India at Ericsson, "LAA is a key evolution of mobile technology and we are pleased to be partnering with Airtel to demonstrate the increased capacity, improved speeds and enhanced user experience through the combination of licensed and unlicensed spectrum

Be ready to be under Vigil of  Security agencies

new MNP regulation 2018  by TRAI 

What is LAA?

Licensed Assisted Access(LAA) is a key technology by which operators can evolve their networks to achieve Gigabit LTE by opening up previously untapped resources of unlicensed spectrum, delivering speeds which were only possible over fibre earlier. LAA is a LTE technology that uses unlicensed spectrum in 5GHz band and licensed 4G band to offer better data speeds for mobile users.

LAA operates in the same 5 GHz band where WiFi operates and when deployed can serve as an alternate to carrier’s WiFi hotspots. LAA can work without interfering with wi-fi using Listen before Talk(LBT) technology that uses channels not used by Wi-fi , if free channels are not available it shares channels equally with the others.


LAA technology was developed and tested by Qualcomm in the year 2016. Qualcomm has pioneered in Spectrum sharing Technologies LAA,LTE-U and Multefire.

 These technologies are key enablers for GHz speeds to be provided in 5G networks.

Main Benefits of using LAA Technology.

Main benefits of using LAA technology over LTE are enlisted below:
  • As LAA uses unlicensed frequency in 5Ghz band no spectrum charges to be paid by operators.
  • Sharing of  data transfer on 5Ghz frequency will increase capacity of licensed 4G band ,as most operators are not having sufficient 4G frequency band to provide high speed data.
  • LAA can enable operators to launch Gigabit LTE.
  • LAA can provide alternate to  Wi-fi hotspots used for high speed data transfer
