What is EVDO BSNL?
What is the Technology used by BSNL to provide High Speed Wireless Internet. BSNL is using EVDO technology to provide high speed wireless internet services. What type of EVDO data cards are being provided by BSNL. BSNL is providing PCMCIA as well as USB type EVDO data card.
What is EVDO device?
Evolution-Data Optimized (EV-DO, EVDO, etc.) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access.
What is CDMA broadband?
Broadband code division multiple access (B-CDMA) is a CDMA-based cellphone technology that uses broadband transmission. It is an improvement over the first-generation CDMA, which uses narrowband transmission. This kind of technology allows for better deployment of transmitter signals.
What is the difference between HSDPA and WCDMA?
WCDMA networks provides max 384kbps speed while HSDPA allowed speeds above 384kbps, the most notable of which is 3.6Mbps and 7.2Mbps. HSDPA has lower latency times and Fast Packet Scheduling compared to WCDMA.
What CDMA used for?
CDMA (Code-Division Multiple Access) refers to any of several protocols used in second-generation (2G) and third-generation (3G) wireless communications. As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth.
Which data card is best for high speed Internet?

What is the speed of Hsdpa?
High-speed downlink packet access (HSDPA) is a mobile communications protocol that belongs to the high speed packet access (HSPA) family. HSDP allows networks based on (UMTS) to have higher data transfer speeds. Current HSDPA deployments support down-link speeds of 1.8MBPS, 3.6MBPS, 7.2MBPS and 14.4 MBPS.
What is the difference between CDMA EV-DO and HSPA?
CDMA EV-DO radio interface bandwidth is 1.25MHz and HSPA utilizes 5MHz bandwidth. 2. Date rates for CDMA EV-DO are around 2Mbps in downlink and HSPA is capable of providing peak rates up to 14.4 Mbps in downlink (HSDPA).
What is the difference between UTMs/HSDPA and EVDO?
EVDO is a CDMA tech while HSDPA is at it’s core GSM based. UTMS/HSDPA in the US is essentially getting leapfrogged by other techs since it’s not really rolled out enough and sprint is already beta testing Wifi like cell techs since it’s deployed EVDO in most coverage areas.
What are the advantages of HSDPA over EVDO?
The biggest actual advantage that HSDPA has over EVDO in North America is that Verizon/Sprint implement EVDO such that you cannot have a voice call and data transfer going on at the same time. GSM providers are already deploying UMTS/HSDPA and CDMA carriers are deploying EVDO.
What are the download rates for EV-DO?
Date rates for CDMA EV-DO are around 2Mbps in downlink and HSPA is capable of providing peak rates up to 14.4 Mbps in downlink (HSDPA). 3.
