Recommended from D-Link About Network Solutions Through the Power Cable

Reluctant to build a cable-based computer network at home? How about a wireless device? Knock thick bulkhead so hard to spread the signal? Do not worry, there is a solution of the easiest computer networks, namely through the grid. 

What could? Of course. Actually, this technology has long been introduced and the manufacturer also becoming mushroomed, D-Link for example. This networking device manufacturer has just introduced the newest Powerline solutions for home users which consists of 2 basic components, D-Link 4 port Switch DHP-342 and D-Link DHP-312 Powerline HD Ethernet Adapter. Both stroked latest powerline technology which is claimed to deliver data up to 200Mbps speed. With the speed of the product was D-Link is expected to solve the current problem of home networks, especially on the availability of bandwidth. 

Our new powerline networking solution is to make the users feel comfortable to design and designing digital home capable of running high-definition media streaming, online gaming and other next generation applications, Please note that the D-Link Powerline device allows the network settings on the home location difficult to achieve by wired or wireless signal. 

With this new powerline networking solutions, each fitted with wall outlet can be used as a network connection fatherly easy connection of digital media devices, game consoles, servers, printers, computers and storage devices throughout the home network. In addition, the Powerline HD Ethernet network adapter can be added to the network connection at home, simply by using a Local Area Network (LAN) that is integrated. Uniquely, all can be operated without an additional adapter cable because it uses the power of ordinary electrical flow and wall sockets for transferring data.

Long Trip From HSDPA to LTE

If you buy a USB modem, you will definitely hear and see the term HSDPA. Of course, when you want to buy the modem you also presented some information on HSDPA, there are states with 7.2 Mbps and there is a mention with the accompanying figures 3.6 Mbps. However, what is the difference in these numbers?

From the information available, HSDPA stands for High Speed Downlink Packet Access, which means as the communication protocol third generation mobile telephony, better known by the family of 3G HSPA (High Speed Packet Access).

It protocols of this type is providing support to all networks using UMTS (Universal Mobile Telecommunications System), which has a transfer speed and data capacity is higher. Today, HSPA support downloads speeds of 1.8 up to 14.4 Mbit / sec. The first phase of HSDPA is specified in 3GPP (3rd Generation Partnership Project) Release 5. This phase introduces basic functionalities that aim to achieve the speed downloading up to 14.4 Mbit / sec. In Singapore. They have implemented this 3GPP-based system so that the speed in the surf using HSDPA USB modem is very pleasant.

The second phase of the HSDPA of course also influenced by the 3GPP, but, in this second phase is determined by what is now the seventh release HSPA Envolved. Data's speeds can reach about 42 Mbit /sec, with the help of an array antenna technology such as beamforming and MIMO (Multiple Input and Multiple Output). Where are beamforming to focus on the performance of the power delivered from an antenna in a beam toward the user so that the MIMO using many antennas on the sending and receiving data.
After HSPA Evolved, the next direction is the E-UTRA which was formerly known as HSOPA. It is a technology that is being developed for the specification of 3GPP Release 8. The project is now known as LTE (Long Term Evolution), which at this early stage to provide support in the form of download service with speeds above 320 Mbit /sec and upload at 170 Mbit / sec.
