Here is something new from Motorola. Said to carry class connections, people who are setting up wireless networks and want longer distance covering may want to check out the PTP 300. The new Ethernet Bridge is said to operate at either 5.4 to 5.8 GHZ with a maximum transfer rate of 25 mbps. Add to that the fact that it can cover of up to 248 km, then this Ethernet Bridge from Motorola looks like a tempting find.
This type of Ethernet Bridge does seem suitable for urban environments. Normally there are some constraints as far as the proper connectivity within networks. Going wireless is something that is common these days and if given a choice, anyone would want to have access to the web wherever they may be. But if you think about it, it perhaps depends on the network coverage that an Ethernet has been programmed for. We all must remember that for most Ethernet setups, there is usually an assigned security name and password to limit the people who want to access the web through it.
If you think about it, this Ethernet solution is highly appealing to the people in the corporate world. It is not something that the average home owner would want to have unless he owns a large parcel of land. Access to the web in the corporate setting is indeed a need especially if you talk about web-based programs and emails used by employees and personnel. But of course, it is still the duty of the network administrator to assign permissions to make sure there is control and the Internet is put to good use.
The boom of wireless technology is obvious and so far a lot of people these days have made it a point to set up a wireless Internet connection in their homes to enjoy the luxury of Internet browsing in their homes, wherever they may be. No longer are you stuck towards staying in one part of your home, normally near where your phone conduit is placed. With the help of a wireless router, you can either place cables or rely on the wireless technology that routers normally come with these days.
Taken as a whole, it is not difficult to install. Knowing the current crop of routers in the market today, most of them are simple plug and play. All you have to is to connect the modem on one end and the RJ 45 on the other. After that, you just have to turn on your computer and make sure you are within range. Once connected, you can enjoy the benefits of surfing the web as you please.
Now that was not so hard. So if you talk about how to set up a wireless network in your home, it is quite easy if you try it out. Do not let the complex design of a router fool you. It is really something that is similar to a jigsaw puzzle.
With that said, it is obvious that setting up your wireless home network should be a breeze. You don’t need technical people to set it up for you, unless of course you want certain restrictions such as placing a username and password so that wandering people don’t get to use your network to browse the web.
The best people to ask these days would be the network administrators. If you have noticed, there has been a lull in the continuous development of high end Ethernet solutions. We have seen the fast paced development which last saw Gbit Ethernet links rule. Since then, we have not heard anything to the latest transition towards the faster 10 Gbit Ethernet technology apparently due to the rising costs of raw materials, most of which are needed to make it all happen.
These days, it is not a secret that everything is going up. New copper cabling and components are getting pricey by the day and with that in mind, it is apparent that there will be hesitation on the part of most companies and networks to consider the high-end cabling solutions.
Data centers in particular, are turning to cost-effective networking solutions such as multiple Gbit Ethernet links that costs less than $200 per port. A 10GE link can cost as much as $2,500 per port as reported.
Hewlett Packard is not using this as a setback to their continuous development. Rather than step back, they are hoping that their move to release its first transceiver modules to carry their 10 Gbit Ethernet over multimodule optical fiber will help nudge the current market towards leaning to new technology. HP hopes its 10GBase-LRM modules help nudge the slow-moving market for 10GE forward.
In a world that is playing along the lines of risky business with consideration towards current economic trends, a pit stop of sorts has hindered the continuous development of the Ethernet solutions we should be enjoying. From what it stands, this push may not only be a move that will awaken the sleeping world of Ethernet and network solutions but can help us continue the network solutions we are all enjoying at the moment.
In networks, we often focus a lot on the cabling and layout to make ends meet. As long as there are the usual RJ 45 tips that can help provide connectivity using the various wiring combinations, all else is taken for granted. But what if you wanted to modify it a bit, provide some assistance towards these connectors to make sure that their connections are locked properly when you connect the network players such as the workstations and the servers?
For added safety, it would be wise to check out these offerings from Tyco Electronics. Some would call these plug kits as useless and added cost but if you want to put premium on security in connections of cabling and the ports, then this is something you should surely check out.
Tyco Electronics offers a line of IP67-rated ODVA-compliant industrial Ethernet connectors, which are suited for EtherNet/IP, DeviceNet, and ControlNet applications.
The modular plugs and jacks connectors offer IP 67 sealing and a quick-connect bayonet coupling that meet IEC 61076-3-106 Variant 1 specifications.
These connectors are suitable for the working environment where anything can happen. Locking your cables securely so that they do not have to be constantly pulled out of the plug is a good want to make sure that you entire network is functioning properly.
Adding something to your network will not hurt. Besides, it is more than putting class to your cabling and peripherals, it is all about ensuring quality network performance 24/7.

We have notice at times that surveillance and security are pretty much evident these days. Apparently this has stemmed from various criminal and terrorist activities to which proper monitoring of activities in both indoor and outdoor areas are pretty much a need.
We normally see them in movies such as CSI (Crime Scene Investigation) and we see the importance of installing these surveillance cams. They are often used as reference points, especially if crimes occur and the need to backtrack certain events to determine what really transpired is a need. We see surveillance cams today but some of them use the conventional analogue units that make use of the traditional coaxial cable. However, Mobotix offers an advanced offering, making use of network IPs which uses exchangeable lenses and operated by power over Ethernet. It can be connected under any local area network and can easily be configured through any standard web browser.
The camera software includes video motion detection and definable exposure zones. It captures up to 30 frames per second, has alarm functions via email and VoIP, and records images up to 2048 by 1536 pixels. This resolution is said to be 30 times that of conventional surveillance systems.
Network cameras allow the transport of video and audio data via digital computer networks rather than the coaxial cable used by conventional analogue units. By using purely digital transfer, the previous limit of 0.1 megapixels is eliminated.
The Mobotix units shift intelligence from the central control unit to the camera. The cameras themselves have integrated software for image creation, image analysis, event control and recording management.
According to the distributor, Mobotix is the only company currently offering network camera systems with the software-based, decentralised system architecture. It also offers video management software for video surveillance systems.

We all know that a Macintosh is something that you don’t see participating in Ethernets and networks these days. Normally, all PCs in a network are Linux or Microsoft Windows based. This is perhaps one of the shortcomings that makes a PC stand out over a MAC. MACs are normally know for imaging and graphics related solutions but not for business operations were data flow and report generation is the usual recourse that most companies look for today.
But just when you thought that this becomes a liability for a MAC, Mac Alliance is working out a scheme to help integrate a Macintosh into a Microsoft Windows environment. Apparently this is to help push the MAC with the hopes it can be in line with the growing needs of business outside the usual imaging and graphics solutions that they are normally pegged to have.
“Since adopting Intel technology in its Macs, Apple has seen rapid growth in its desktop and laptop sales, up 51 percent last quarter on the same period in 2007, and outpacing the PC market,” Sherylin Dahl, senior partner manager at Parallels told InfoWorld. “This is partially due to tools such as Apple’s own Bootcamp and virtualization solutions such as Parallels Desktop for Mac, which enable users to run Windows or Linux applications on a Mac, addressing the compatibility issue that has traditionally acted as a barrier to widespread Mac adoption. The Enterprise Desktop Alliance aims to advance this goal by educating the market and further encouraging and enabling Mac adoption in the enterprise.”
One way the alliance plans to help push its initiative is through its education services. The EDA plans on hosting a series of events, including Webcasts and seminars, and will also provide white papers, product information, and other resources on its Web site.
If you have been versed with networking, you know that there will be a lot of work to be done. Other than the web, a MAC is normally not seen as an active contributor in networking environments. But anything is possible and perhaps with the joint efforts we can see how a MAC can be of use in a usual business network environment.
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.
