India's Worldphone Yet to Come!

A Worldphone or globalphone is considered to support most available network across the globe.

In India there are several technologies are being offered over different spectrum bands. Here goes the list:

GSM/EDGE (2G) - 900 MHz
GSM/EDGE (2G) - 1800 MHz

CDMA 1x/Rev0/RevA/RevB - 800MHz

HSPA (3G) - 2100 MHz
HSPA (3G) - 900 MHz

LTE-TD (4G) - 2300MHz
LTE-FDD (4G) - 1800MHz
LTE-FDD (4G) - 800MHz


What we are missing here:

LTE over 700MHz
LTE over AWS band (1700MHz-2000MHz)
LTE on 2600MHz
CDMA over 450MHz
CDMA over 800MHz
TDMA (as in China)

At present I guess no device support such long list of networks over such extended bands. 

Reliance Jio - Latest Stories ( August 2015 )

Reliance Jio Infocomm, the telecommunication arm of Reliance Industries is all set to begin commercial operations by December 2015. Though we are yet to know the official launch date there are some updates regarding Reliance Jio's progress towards the commercial roll out. 

Cheap 4G Smartphones under ReConnect Branding

Before Jio's data services come to market, as early as by middle of September this year RIL will launch LTE-TD handsets (Android smartphones, mostly) for everyone - from Rs 5000 to Rs 25000 price bracket. It will have it's own branding - ReConnect, which is already rolled out as Reliance Digital stores are selling such smartphones and tablets (made by OEM). Jio has tested devices (dongles, WiFi Hub, smartphones, tablets and others) from 28 OEMs. It is expected that Jio's ReConnect smartphones will have both LTE-TD (2300MHz) and LTE-FDD (1800MHz and 800MHz) support. I am not sure these smartphones would support 2G CDMA or GSM network, however expect VoLTE in-built. Jio will rely heavily on its existing Reliance Digital platform to reach masses. 

Verizon Aggressively Backing for VoLTE before Winding up Traditional Voice

American telecom giant Verizon is working hard to make Voice over LTE (VoLTE) a default feature for its all customers. Presently worldwide carriers are shutting down 2G networks to make room for LTE deployments. Verizon is also walking to it – the company has plans to phase out its entire CDMA network by 2021. But before that they need to have a robust 4G network running.

Now Verizon’s VoLTE feature is an opt-in feature where customers need to select this feature on their VoLTE enabled smartphones. David Small, executive vice president of wireless operations at Verizon Wireless informed that more than 4 million customers are using this feature, which will be the default voice option to all customers in due course.

Verizon has launched VoLTE as Advanced Calling 1.0 - the initial version of VoLTE. Currently they have 25 smartphones supporting VoLTE. 

CDMA Logs

This article is a backup article for any future interest. At present India has no active CDMA service. I had this document long time in my PC, and found in 2019. However I am sharing it as anyone might be interested in CDMA history in India.

Huawei EC325 Data Modem Unlock ....

This device comes locked by the operator and cannot be used on other operators. There is a way we can unlock this device. Download the Flasher for HUAWEI data card. This software will erase the EPROM of the device and install an earlier version of the Firmware ( version 25.07.016). This software is tested. I have successfully flashed my HUAWEI data card and it is now working on any CDMA network.

BiswaBangla Net - Another free WiFi Zone at Kolkata

Last week I had an visit at Charnock Hospital, near Haldiram- VIP Road. One of close person was operated for TURP, and as schedule was after 10pm, I reached there around 11:40pm. While waiting outside the OT Complex, I found that there is a open WiFi network around. 

I can't remember when WiFi on the strech of Biswa Bangla Sarani was announced (probably in the winter of 2014-15), however after trying Tata Docomo, Ozone and RJio's WiFi I once found it's a free internet (for 30minutes, though) zone (of Kolkata) I got interested to check that out. 

** In June 2014 HIDCO announced this WiFi services across the 10.5 Km stretched Major Arterial Road connecting Airport to Saltlake sector V. The road is also announced as green corridor where no billboard is allowed. There is a plan to extend Wifi services on another 6 Km to Chigrighata crossing on EM Bypass. In January 2015 the services become open for public use. **

'BiswaBanglaNet' is the name of Wifi network, detected by my phone. It's an open network - but to access internet you need to log in (web log in).

• It offers 30 min of free usage
• User registration is same as Ozone/Tata Docomo/Jionet - you give your mobile no, receive a text from DZ-BBSNET with username (your mobile no) and password. On the log in page, you can the see counter of 30 minutes.
