At times when you disconnect a network cable from a hub or router, there is a matter of trying to make sure that electrostatic discharge (ESD) may tend to cause problems as perhaps sudden issues of inoperability. Some may attribute it to loose cable ends on the usual RJ45 jacks but then again there is more towards this issue than blaming it on the cabling.

When you leave a port open, it is susceptible to various problems. Thought it may not be much of an issue, it is better to make sure that these networking channels are given the same attention towards making sure that once a network cable is once again plugged in, it will render the same quality and function it was known to have before it was unplugged.

To help protect network environments, OnChip Devices has developed a Low Capacitance Diode Arrays for Ethernets to make sure that maintenance and safety within the networks is sustained. The ESD pulse can be introduced directly into the open port, or into the disconnected end of the cable. Without sufficient protection, the Physical Layer Transceivers (PHY) and the Controller chips can be rendered inoperable since they are routinely manufactured using 0.18-micron and 0.13-micron technologies. These small geometries are extremely sensitive to ESD.

So if you think it would be best to simply keep these ports plugged, remember you don’t have to limit yourself and be afraid to plug them out. There are solutions offered for them and for people who are expected to keep networks abreast, this diode offered by OnChip Devices is indeed something you may want to consider.

With data serialization, higher bit rates, and increasing screen resolutions, today’s computers and consumer products require uncompromising levels of protection against ESD with ultra-low line capacitance to preserve signal integrity. Protecting these systems with OnChip’s silicon based diodes has become an essential part of the product’s reliability. OC1214-02MR offers channel-to-ground capacitance of less than 1pF and the channel-to-channel capacitance of under 0.4pF. The device clamp voltage is below 10V which virtually eliminates IC latch-up and soft errors.

Don’t be to excited nor overwhelmed when you have saved up to buy your first wireless router. For the normal consumer, it seems that going with the trends is as simple as installing a wireless router in between your DSL and home network. In short, standard people are satisfied knowing that in any place of their home or office, wireless Internet access is within reach as long as they are within range.

Rather than paying for WiFi access, establishments and homes are slowly appreciating the benefits of installing a wireless router today. Rather than paying for a certain number of hours to get online, why not integrate your existing Internet service through a wireless device?

But while that is indeed something to look forward to, becoming advanced about the technical benefits of differentiating the various routers in the market today will surely set in.

For the record, here are some key points to consider when you purchase a new or your upgraded wireless router. Don’t be surprised about the technical specifications. They speak for themselves if you read on them closely.

Standards
802.11b
One of the oldest wireless standards, it provides data throughputs of 11 Mbps. Although such data throughputs are sufficient for casual browsing and Internet access, we recommend you go for a product that offers higher performance.

802.11a
Many wireless routers support the 802.11a standard. This standard is not so widely supported and will not work with your existing wireless notebooks. The performance advantage provided by this standard is minimal compared to the current 802.11g standard.

802.11g
This is the current standard supported by laptops. Almost all wireless routers support this standard and you can be sure about its compatibility with current generation laptops. It supports a maximum throughput of 54 Mbps.

Super G
Many routers offer enhanced “g” modes or Super G modes that make use of framebursting and compression technologies to deliver greater speeds and range compared to that of traditional 802.11g products. Product manufacturers claim a 20 to 30 percent throughput improvement over standard 802.11g products. In our range tests, these products did deliver better throughput and range than regular 802.11g products. A word of caution here-you will not be able to make use of the extended range and performance of your wireless router using a standard Centrino laptop-you will have to buy a PCMCIA card along with the router that supports the relevant performance boosting technology.

MIMO
MIMO is the new marketing buzzword for the yet to be ratified 802.11n standard. If you want faster speeds, MIMO is the way to go. MIMO uses multiple transmitter and receiver antennas for higher data throughputs and uses multiplexing to provide for a greater range. Although MIMO products are technically superior than 802.11b/g products, but many of them come at a higher price point.

Security
Almost all modern-day routers offer WEP and WPA PSK (preshared key) encryption. Buy a router that supports the newer WPA2 standard that provides better security compared to simple WPA and eliminates flaws of the WEP encryption standard. Those better suited to business support 802.1x-based authentication. For improved security, we recommend routers that support SPI (Stateful Packet Inspection) firewalls as opposed to simple packet filtering firewalls.

For technology to make its way properly in integrating business with the benefits of automating normal day operations, cabling and networking planning is a need. But it doesn’t stop there. Remember, you also have to consider what type of cables to use that will be able to handle the data flow. Networking experts normally suggest the CAT 4 or CAT 5 cables. For the normal person, these are too technical in nature and chances are you would go with the cheaper one. That does not follow all the time.

CAT 4 Cabling (Category 4 Cables)

From Wikipedia:

Category 4 is a description of a cable that consists of four unshielded twisted-pair (UTP) wires with a data rate of 16 Mbit/s and performance of up to 20 MHz. It was used in token ring networks, 10BASE-T, 100BASE-T4, and is no longer common or used in new installations. It was quickly superseded by Category 5/5e cable, both of which have 100±15 ohm impedance.

Depending on your network needs, the CAT 4 cabling allows optimized performance of up to 20 MHz and used in toke ring networks. This type of cabling is normal for starting companies who are fine with the standard data transfer rates and are not planning to upgrade to use other types of transfer that include audio and image transfers in their network.

CAT 5 Cabling (Category 5 Cables)

From Wikipedia:

Category 5 cable, commonly known as Cat 5 or “Cable and Telephone”, is a twisted pair cable type designed for high signal integrity. Many such cables are unshielded but some are shielded. Category 5 has been superseded by the Category 5e specification. This type of cable is often used in structured cabling for computer networks such as Ethernet, and is also used to carry many other signals such as basic voice services, token ring, and ATM (at up to 155 Mbit/s, over short distances).

This is the cabling that is recommended for the normal day businesses. You really never know when you may decide to upgrade your current system transfers. At the rate that technology is being used today, hardware is not the only thing that is upgrading with the times; software and programs too.
