Glad that we are developing in broadband arena, even tho’ our connection speed is not yet satisfactory. We are happy to hear the news of launch of IP CDMA by Nepal Telecom recently. Based on user’s questions on TechSansar’s Facebook page and Twitter, we have compiled frequently asked questions (FAQs) about IP CDMA broadband service in Nepal by Nepal Telecom.
Nepal Telecom (NT) is finally all set to deploy IP CDMA broadband service by December 2011 which was announced back to 2009. The target is to reach broadband to another 2 million (20 lakhs) and more customers in suburb n rural areas. Using this service NT customers would enjoy 3G facilities based on EVDO technology – that means high quality of voice and data services. But NT has not clarified if this is the beginning step of the 4G telephony service in Nepal because IP CDMA could be distributed to customers with a fixed IP like a cell phone number and customers can make voice calls directly from IP to IP, or use data services as per their requirement.
Introduction:
Mobility is the most important feature of a wireless cellular communication system. Usually, continuous service is achieved by supporting handoff (or handover) from one cell to another. Handoff is the process of changing the channel (frequency, time slot, spreading code, or combination of them) associated with the current connection while a call is in progress.
Soft Handoff in Mobile Communication
In first-generation cellular systems like the Advanced Mobile Phone System (AMPS), handoffs were relatively simple. Second-generation cellular systems like the Global System for Mobile Communications (GSM) and the Personal Access Communication System (PACS) are superior to first-generation ones in many ways, including the handoff algorithms used. More sophisticated signal processing and handoff decision procedures have been incorporated in these systems. The control/decision structures have been improved so that in progressing from network-controlled toward mobile assisted handoffs (MAHO) or mobile-controlled handoffs (MCHO), the handoff decision delay has been substantially reduced.

As we always say that Telecommunications is the only field in Nepal which attracts enough public attention and is more developed compared to other areas. Nepal Telecom has planned to come up with two new broad plans. NTC wants to set up a DTH Hub, expand CDMA network and EVDO. [Read more...]
Finally Nepal Telecom (NT) has slashed some of the subscription charges and calling rates on its major services including 3G, GSM, CDMA and PSTN International (ISDN) calling rates. However, the lowered rates are not much likely what the subscribers expected from the country’s largest telecommunication company.
