In 2011 when skycell was merged with Airtel the company got AMC contract for cellular sites. When Airtel went for expansion in 2002 they got projects in Tanjore and Trichirapally districts. They designed and implemented electrical scope for the cellular sites. Gradually in 2003 , GKAR entered into Kerala state Highway connectivity coverage from Cochin to Kasargod.

In 2005 Mr Rajasekar moved to Chennai and opened an office at kutchery Road,Santhome. He began getting aggressively active in telecom projects in ROTN (Rest of Tamilnadu). In 2006 he formed a separate company and started AMF panel manufacturing unit at Guindy exclusively for Telecom. They got orders from Aircel and all Telecom operators and became the key manufacturer and supplier for PMU( power management unit) in Pan India operation.

Parallelly GKAR company gained its strength in projects also which took off everywhere including Andaman, Hubli, Tamilnadu and Kerala. After the 2010-2011 2G scam, all Telecom operators had to temporarily stop all the expansion projects all of a sudden. Again in 2014 they began 2G to 3G migration job. When the TRAI ( Telecom Regulatory Authority of India ) passed a GO for the tower sharing concept to reduce the radiation, all the Telecom operators had to share the infrastructure.

Indus Towers came to the picture then. Airtel, Vodafone and Idea became the shareholders for Indus Towers. Their concept was to Build, Operate and Lease (BOL). Many Telecom project companies failed to survive due to the drastic decrease in the number of projects. Technology upgradation became very simple as a result. That was when GKAR focused on diversion. Between 2011 and 2014 GKAR took up projects in a few core areas in power project sector for ABB and BGR. At the same time the company started doing Class I projects in the Govt Public Works Department (PWD) too.

After the 2014 flood disaster,GKAR got a tender allotment from a reputed non government organisation to construct 165 houses and 16 schools in Chidambaram and Cuddalore district as a relief measure.The challenge was to deliver the entire project in 50 days schedule for which Mr.Rajasekar got awarded for his outstanding performance. The company also entirely re-structured and designed the Ashok Nagar Central Public Library Chennai, after the disastrous floods.He created an exclusive kids reading section with bright and colourful furnishing and facilities.It was very much appreciated by the public for his innovative concept.In 2016-2017 the library got awarded for the Best Infrastructure facility.

After 2015 Mr Rajasekar began a new Vertical in hospitality and hi-tech agricultural infrastructure. To begin with, he ran a full fledged service apartment in Chennai to equip himself in the same.His passion for agriculture drove him to travel extensively and explore the latest methods implemented respectively. The concept of ultra high density plantation fascinated him and he acquired land to do corporate farming and try his hands on it in which he successfully reaped the first crop with good expected quantity of yield. As a pilot project he combined both Hospitality Management and farming to introduce a brand called "Talking Trees".
