Motorola SB6141 - The Latest Motorola DOCSIS 3.0 Cable Modem Is Here

AppId is over the quota

First of all before I tell you about the Motorola SB6141, the latest DOCSIS 3.0 cable modem from Motorola in this review, it is important to at least have a high level of understanding of what the DOCSIS 3.0 specification is and what are the advantages it provides to a modem that is built to that specification.

DOCSIS stands for Data Over Cable Service Interface Specification. As you can tell from the version number, the 3.0 specification is the third and the latest version of DOCSIS; the 3.0 specification was actually released way back in August 2006 by a consortium of technology companies led Cablelabs of which Motorola is a member to use channel bonding technologies to provide ultra fast broadband services.

So how does this channel bonding technology helps to improve the data transfer speed? In simple terms, a modem like the SB6141 utilizes the channel bonding technology together with the DOCSIS 3.0 standard to cleverly harness the extra unused bandwidth capacity to provide the boost to users.

Imagine combining eight already large data pipe of 40 Mbps of data per channel to give you a theoretical total downstream capacity of 320 Mbps? In the theoretical or optimal case, you could utilize data rates of more than 320 Mbps downstream and 160 Mbps for upstream channels.

However do note that like all modems, actual data throughput will generally be less due to physical layer overheads e.g. error correction coding, burst preamble, guard correction etc

Also do note that you get what you pay for. For example if you subscribe to a 20 Mbps package from your ISP, you will not be able to take the full advantage of the SB6141's data capacity due to the capping from your ISP.

Even though users cannot make total use of its theoretical through put, most users of the Motorola SB6141 would feel the speed surge immediately when they switched over to the SB6141.

The Motorola SB6141 supports both IPv4 and IPv6 and is also backward compatible to the original DOCSIS/EuroDOCSIS and includes an internal filter to eliminate potential interference from MoCA signals' inter modulation beats.

The Pros and Cons of the Motorola SB6141

No matter how good a product is, there will always be some weakness. However the SB6141 is an excellent product that has evolved from its solid predecessors the Motorola SB6121 and SB6120, so there are few flaws. In fact these should not be termed "Cons" as it is not the weakness of the Motorola SB6141 but rather the accessibility provided by the ISP Comcast:

Comcast does automatically not support the SB6141 at the point of writing. However some customers have managed to get Comcast to manually provision their SB6121 for them. Once that has been done, s reset signal will be sent to the modem and you have to repower it to get it working. Also to make sure that you buy the appropriate Comcast package to make full use of the Motorola SB6141's capabilities i.e. you pay for the speed

These are some of the Pros of the Motorola SB6141

It now supports AES traffic encryption for enhance securityEasy to set upHas a build-in internal filter to reduce potential interference from MoCA signals' inter-modulation beatsCheaper than its predecessors the Motorola SB6121 and Motorola SB6120Capable of channel bonding up to eight downstream channels and four upstream channels. This offers a potential increase in data rates of over 300 Mbps for received data and over 100 Mbps for sending dataShares the same firmware image as the hugely popular SB6121 and SB6120. This helps to reduce operator qualification time and eliminates configuration management problems for the ISPs

Overall, if you are looking for speed and if you are willing to pay for the speed from your ISP, then the Motorola SB6141 is the modem to go for. Click here to buy the Motorola SB6141.

The XOOM-COMB Calls For Dare! (Motorola XOOM Review)

AppId is over the quota

Xoom is an android iPad delivered by Motorola in partnership with Google. It uses Google's mobile operating system Honeycomb version 3 as its operating system. It definitely has rocked the market of tablet purchasers. The Xoom has proven to be a stiff contender. The Xoom is equipped with all the fancy and impressive new hardware and software including the one redesigned by Matthias Duarte. The features include 32 GB internal memory, nvidia tegra-2 based slate, ddr2 ram of 1 GB, 1 GHz processor, a capacitive display screen of ten point one inches, 3g capability, HD video facility, both rear and front facing cameras and a great deal of wireless choices.

The Xoom has a very competitive design and build. The Xoom can be upgraded to 4g network and hence this makes both the device and its market future proof. So obviously it comes at a hefty price of seven hundred and ninety nine American dollars which makes it an expensive bit of technology to possess, with all its formidable features and Google's software packed on the inside. The Xoom can boast to represent a whole new generation of tablet evolution. The design of the Xoom may be conventional as the usual tablet form of design cannot be done away with but it definitely has a handsome build. It has machined metal, curved corners and the front is covered totally by the giant screen. Design cannot be innovated as the general market design has to be considered but it is well accepted by the consumers. The device cannot be called massive with its height being six point six inches and the thickness being only point five inch. The tablet has better usability in the landscape mode rather than the portrait mode and some consumers complain about certain downloaded data not functioning in the portrait mode.

The Xoom has one big deficiency which is it cannot be charged unless it is switched off. The front facing camera is situated at the dead centre of the two logos of Motorola and Verizon. The two volume controlling buttons are located on the higher left hand edge of the body of the Xoom and the external memory card slots are also situated around the volume controls. The dock sensors and the micro USB jack ports are situated together on the bottom. The power or sleep button is located weirdly beside the flash and the camera lens. The Xoom has higher resolution and larger display than the iPad. The aspect ratio of the Xoom is also different from the iPad, the former feeling a little taller or longer. Some people might feel the usage of the portrait mode a little uncomfortable due to the dimensions but it is definitely not too bad to break the deal. The pixel density is a little poor and suffers in the competition. The audio is pretty clear at the moderate volume level. Increase in the volume created indistinct sounds like distortions in the notification tones, ringtones etc.
