What is R99 in telecom?

In R99 the RNC is in charge of everything relating to handling of radio resources; scheduling as well as selection of transport format and setting of target for power control (outer loop power control) in order to provide the data rate required for the specific service for the connected UEs.

What is R99 in UMTS?

Besides, the UMTS system still accom- modates a significant amount of Release 99 (R99) traffic such as voice telephony. In R99, user traffic is transported via Dedicated Channels (DCHs) over the radio interface.

What is the difference between R99 and HSDPA?

R99 supports CS Voice/Video and PS up to 384Kbit/s DL/UL. HSDPA with Class 10 devices can support on a shared channel up to 14.4Mbit/s. All of this is carried on Wideband CDMA Channels. Further reading can be seen on the 3GPP standards website.

Is WCDMA GSM 3G?

WCDMA (Wideband Code Division Multiplexing Access) and GSM are two technologies that are used in mobile telecommunications. The difference between these two is that GSM is a 2G technology and WCDMA is a part of the newer 3G group of technologies.

Is HSPA 3G?

HSPA (high speed packet access) is a third-generation (3G) mobile broadband communications technology. The term HSPA actually refers to two specific protocols used in tandem, high speed downlink packet access (HSDPA) and high speed uplink packet access (HSUPA).

Is WCDMA faster than GSM?

The efficiency and speed are better in WCDMA due to the technology used in the network and the coding channel separating the data columns in the system. This helps to manage the communication channel well in the network and the communication is done faster than GSM. The efficiency and speed are less in GSM.

Does WCDMA support 4G?

In general, WCDMA is considered as 3G technology while LTE is considered as 4G technology. LTE provides higher data rates than WCDMA by achieving higher spectral efficiency.

Is LTE a 5G?

In short, the G stands for generation, so 5G is the collective term for the fifth generation of mobile network technology. LTE stands for Long-Term Evolution, and it’s a 4G technology. The newer 5G is not a replacement for 4G, so you’ll find LTE and 5G technology working together for the foreseeable future.

Which is faster WCDMA or LTE?

LTE provides higher data rates than WCDMA by achieving higher spectral efficiency. Also, LTE technology provide more flat architecture that is mainly focused on IP packet based services than that of the WCDMA. LTE topology is much more flexible and scalable than of the WCDMA due to the flat nature of architecture.

What is the difference between R99 UMTS and WCDMA?

R99 stands for the year 1999 in which UMTS specifications were released by 3GPP. WCDMA stands for Wide-band Code Division Multiple Access used in access part of 3G technology.

What is the difference between HSPA and R99?

R99 (generally known as Release 99) is a handset data bearer capacity. You can get data speed up to 384kbit/s on R99 series devices. HSPA means high Speed packet access. It is combination is HSUPA (High speed uplink packet access) & HSDPA (high speed downlink packet access) that support maximum 42Mbit/s.

What is the difference between wideband code division multiple access and GSM?

WCDMA stands for Wideband Code Division Multiple Access and GSM stands for Global System for Mobile Communication. Both are mobile communication standards that are used in mobile networks to keep up all communications between mobiles.

Does it matter if I use CDMA or GSM network?

Whether you use a CDMA or GSM network, it does not matter. What matters is the coverage from the CDMA and GSM networks. Luckily, US Mobile has excellent cellular coverage using the best GSM and CDMA networks in the US.
