TCS flouts PoC conditions for 4G network: BSNL

The state-run telecom operator Bharat Sanchar Nigam Limited (BSNL) has expressed dissatisfaction with the progress of the fourth generation or 4G-led proof-of-concept (PoC) of Tata, referring to the lack of roll-out of the desired radio network despite the extended deadline Consultancy Services (TCS) led consortium.

In a three-page letter to TCS, dated November 8, 2021, BSNL stated, “it is to emphasize that M / s TCS has not installed RAN (radio access network) even in a single location under the terms and conditions of EoI (expression of interest) until date, “and further requested the Tata Group to expedite the deployment of equipment.

The state-run telecommunications company has also raised concerns about the availability of radio equipment, saying that “based on the reports submitted by M / s TCS, only 20 watts of radio in a few bands have been delivered, which is not in line with the terms and conditions of EoI and added that “it is understood that M / s TCS” is developing these remote radio heads (RRH) now that the product is not readily available. “

Following BSNL’s EoI in January this year, the TCS-supported consortium, which included the state-run Center for the Development of Telematics (C-DoT) and Bengaluru-based Tejas Networks, was nominated to supply core and radio equipment to the test sites in a prelude to telco’s ambitious 4G rollout strategy.

By July, Tata Sons had strategically acquired 43.35% of the shares in domestic gear manufacturer Tejas Networks.

Last month, Telecommunications Minister Ashwini Vaishnaw and Secretary K Rajaraman made a first call to the VoLTE (voice-over long-term evolution) test network, boasting about it as a “made-in-India” achievement.

BSNL further stated in the letter that a change of location for the implementation of a sample network can not be taken as an excuse for any delay.

The Mumbai-based company had selected 15 sites out of a total of 31 for testing Indian Nuclear and Radio Access Network (RAN). With two sites interfering with All India Radio (AIR) and Doordarshan services, BSNL had offered alternative sites to the IT integrator.

TCS chose Faridabad to establish a trial network beyond Pune in the 850 MHz and 1800 MHz bands.

However, the telecommunications company also pointed out delays in radio production and said that eNodeB must be delivered in accordance with the Telecommunication Engineering Center (TEC) general requirements, and each transmission port must be able to deliver RF (radio frequency) power of 40 watts per second. antenna input port for both FDD (Frequency Division Duplex) and Time Division Duplex (TDD).

In addition, it requested TCS to supply a macro base station consisting of BBU (baseband unit) / RRH and Massive Mimo to be delivered through a single original equipment maker (OEM) under the terms issued in July 2021.

In July this year, the TCS-supported consortium was asked to present its technical evidence within a time frame of 120 days or 4 months. Meanwhile, the deadline has now been extended to 31 December 2021.

“We can not comment on strategic commitments. However, it can be noted that we, together with our partners, are committed to the successful implementation of the proof-of-concept, and we are making good progress towards achieving the goals,” TCS said in a statement. to ETTelecom.

Recent developments have come on the back of India’s Pradeep Kohli – led multinational Mavenir’s heavily worded letter to BSNL dated October 12, 2021, which said “major concessions were given to the selected consortium”, while clarifications made by potential bidders applied for, was rejected in a prior bidding meeting.

It said all Indian companies should be invited to PoC, adding that the 20 watt radio instead of requiring 40 watts meant a significant deviation from the EoI requirement, which could further escalate the cost of state-run telecommunications company.

BSNL should invite all core OEMs registered in India who are willing to offer RTU of core software at no extra cost with a condition of putting source code on an Escrow account, Mavenir added in its letter last month.

Additionally, the reservation criteria for state-owned ITI were also revised so that radio networks could be provided by an Indian “technology partner,” it said, adding that the source code requirement for core equipment was further tailored.

BSNL’s bid to launch next-generation commercial services hit several roadblocks, and the telecommunications company had to change the bidding conditions to include home-made companies to demonstrate technological provenance following the recommendations of the Telecommunications Division’s (DoT) Technical Committee.
