Calcutta Telephones – the Kolkata metro unit of Bharat Sanchar Nigam Limited has listed the details of CDMA 1x and EVDO BTS location on their website.
As per information given there, CalTel has installed 316 CDMA BTS, among them 143 BTS are EVDO enabled, while 173 BTS are just equipped with CDMA1x. That means only 45.3 % BSNL’s CDMA BTS are EVDO enabled.
It also reveals that in Bidhannagar, City, North Kolkata and South Kolkata you will get quite vast coverage of BSNL EVDO. While in sururban areas like Alipore has only 34% of BTS with EVDO enabled; while Barrackpore and Srirampore area has less than 10% of BTS with EVDO enabled.
There is high demand of BSNL EVDO in Kolkata sub-urban as BSNL offers true unlimited data usage on EVDO at the cheapest price and these areas have lack of fibre based broadband operators like Reliance, Alliance, Meghbela and Airtel while 3G/HSPA services are quite costly.
As BSNL has chosen Huawei, ZTE and Alcatel-Lucent for their network expansion we only can hope that company will expand EVDO network in Kolkata’s sub-urban areas.
