How to choose the Best Wireless Network Card

The role of a wireless network adapter is like other normal network adapters, it is applied to connect the Lan. Wireless network adapter is just a gadget to receive and send signal and it only works in the Wlan. Agreeing to their different ports, wireless network adapters are divided into some types: Pcmcia adapter, Pci network controller, Mini Pci adapter, Usb net card, Cf/Sd net card and so on. And in our daily life we generally use Pcmcia card (only used in laptops), Pci net card (specially used in desktop computers) and Usb network card (available both in laptops and desktop Pcs). Now the most beloved broads are Intel, Tp-Link, Fast and Tenda etc, and the main rate is 54M and 108M. But the operation of these devices is not all the same, it varies in signal quality, stability and also price.

Signal quality

If you use a laptop, well then it regularly would have a Pcmcia wireless network adapter built-in this machine; if you have a desktop, it's best to choose a wireless Pci network adapter for a better signal quality, because this card has an external antenna; if you feature the convenience, a wireless Usb network adapter may be more favorable for you, but its signal is not so good as that of the other two cards in the same condition. In a word, without other aids like prolongation lines, the signal ability of the Pci card is the best, second is the Pcmcia card and next the Usb card.




Stability

Considering the Pcmcia net card has to supply power when working, it is lacking in heat dispersion. Since the Pci network adapter is inserted in a Pci slot, it has no question in power supply, as for its cooling condition, it is also superior to other two cards. Compared with Pcmcia card and Pci net card, the power supply of a wireless Usb network adapter is not so stable, and it is also deficient in heat dispersion.

Price

With the same brand, similar features and on the near dates of launch, a wireless Usb network card is relatively more expensive, and the price of a wireless Pci net card and a Pcmcia card is pretty much the same.

mobile Smart Phone, Which One Should I Choose?

I have been reading a lot of threads about mobile phones on dissimilar forums and sites. Most of the threads are complaints about the selection of phone that the thread writer chose. To respond these complaints, I can sum it up in one word, 'Requirements'. As a Technology firm Analyst, every time I am asked to improve or improve a process or function of a software package, the first thing I do is regain requirements. Requirements are primary to translate what the client or customer thinks they need into what they legitimately need. This process can also be used in personal decisions along with technology decisions such as determining which mobile phone will best suit your needs. To justify how this process works, I will use my own mobile phone selection as an example.

The first thing you have to do is 'control the Wow factor'. It's easy to make a bad decision if you give in to the cool features of a new product, some of which you may never use, while giving up features you legitimately need and would use daily. You need to hesitate long enough to consider your requirements. The best way to do this is to list your requirements in a spreadsheet. This is your very first step in the process.

The first thing I did before choosing a phone was to list my requirements. In my case, the first requirement was choosing the provider with the best association vigor at both my house and my work place. Not only will this decision help to narrow down your choices of phones because not all phones are available at all providers, but it is also one of the most leading requirements because what use is a cool phone if you can't make a call or receive a call consistently. Depending on where you live, you may only have one selection of a provider or you may have many choices. So your first requirement, list all of the providers that supply optimum assistance in your area. Now you have a subset of available phones to assess to your requirements.




Next, start construction your definite phone requirements. Be as definite as possible. Normal or ambiguous requirements are considered to be not valid because they do not supply you with definite enough facts to fulfill the requirement. An example of this would be a requirement such as 'the phone should be easy to use'. This is not a valid requirement because 'easy to use' can be mean something dissimilar for dissimilar users. So, be specific. Here was my list of requirements.

1: Seamless integration with Microsoft Office products that I use on my laptop/desktop. What this means is that I should be able to copy an Excel or Word document to my phone without conversion and be able to not only read it, but edit it. Since I use Microsoft products in my work daily, this requirement is very leading so that I do not have to lug my laptop to every meeting. I can use my smart phone to bring up facts for the meeting or even modernize documents and take notes (using Microsoft OneNote) during the meeting.

2: Seamless integration with my email accounts and the potential to send and receive text messages.

3: The phone must have built-in WiFi so that an external card does not have to be inserted replacing the internal memory card.

4: The potential to use my phone as a network way point so I can associate to my work folders using my laptop even if I am out of range of my work or home wireless way points.

5: The potential to continue to use the software I have purchased from previous phones.

6: The potential to store my media (pictures, videos, music, etc.) on a memory card and way them using the on-board software as if they were stored in the built-in memory. This is leading since we like to take a lot of pictures and by having them on the phone eliminates the need to keep photos in my wallet.

7: Touch screen is preferable since I have always had problem using the small keys on a phone keyboard, even the slide-out variety.

8: Qwerty keyboard is preferable. I have never been good at using a approved phone keyboard which requires pressing one key manifold times depending on the character you are typing.

9: Bluetooth built-in. This is preferable to using wired earphones for listening to music and making/answering calls.

All of the features I missed in my requirements are icing on the cake and not considered truly requirements. The next step is to prioritize your requirements by aligning them in order with your most leading requirement first, next leading requirement second, etc. In my case, I found that I automatically listed my requirements by priority, so I could skip this step.

Now that I have my requirements, I listed all of the phones that were available at the providers I listed in the first step where I listed the providers with the best assistance in my area. Once you have your list of phones, start eliminating the ones that do not meet your first 3 to 5 requirements. If you find that this step eliminates all of the phones, you may have to revisit your requirements as they are beyond current technical standards. For instance, if you have a requirement that states 'the phone should be able to converyance me to work instantly', your requirements are a diminutive far out for the current state of technology. You may want to save this requirement in a isolate list called 'future requirements' or 'nice to haves, but not required'.

Once you have eliminated the phones that don't meet your top requirements, you should have a subset that you can now look at more intimately to see which one meets most of your requirements. In many cases, you will not find one that meets all of your requirements, so you need to find the one that meets more of them than any other phone. In my case, the Htc Hd2 met all of my requirements as seen below.

1: Requirement met due to the Windows mobile operating theory on the phone with built-in Office Mobile.

2: Requirement met. It allows email account to be setup out of the box and handles text messages using either the Htc Sense tool or Microsoft texting tool.

3: Requirement met since it has built-in WiFi.

4: Requirement met with an add-on schedule that is provided free by a third party developer for the Windows mobile operating system.

5: Requirement met since my previous 3 phones were also Microsoft mobile phones.

6: Requirement met since the phone came with a 16Gb memory card and the potential to point my media applications to store and view media on the memory card by default.

7: Requirement met since it has a multi-touch screen.

8: Requirement met since it has an on-screen Qwerty keyboard with larger keys than my previous phone's slide-out keyboard.

9: Requirement met since it has built-in Bluetooth.

The majority of users that I have seen complain about the Hd2 would have been happier with their phone selection if they had listed their requirements first. In their case, the Hd2 may not have been the ideal choice. This process works great for any decision from buying a stock like a car or Tv to buying a assistance like insurance. Try it the next time you have a decision to make. I think you'll find that you made a best decision.

How to choose the best wireless network card

The role of a wireless network card is like any other normal network card, is applied to the LAN connection. Wireless Network Card is a device for receiving and transmitting the signal only works in WiFi. PCMCIA adapter, PCI network controller, Mini PCI adapter, USB adapter, CF / SD card and so on network according to their various ports, wireless network cards in different types. Eour daily lives, we mainly use the PCMCIA card (used in laptops), PCI network card (used in particular in the desktop computer) and USB network adapter (available in both laptops and desktop PCs). Now the woman is the most popular are INTEL, TP-LINK, FAST and tent etc., and the key is 54M and 108M. But the performance of these devices are not all equal, varies in signal quality and price stability.

If you have aLaptops, although it would normally have a PCMCIA wireless network adapter built this machine, if you have a computer, was best with a wireless PCI adapter for a better signal quality, because this card has an external antenna, if it is possible to highlight the convenience of a USB wireless adapter network may be more suitable for you, but the signal is not as good as the other two cards in the same condition. In aWord, without other aids such as guides, the signal quality of the PCI card is the best, second only to the PCMCIA card and USB adapter.

Stability

In view of the PCMCIA card has the power network in the workplace is free of heat distribution. Since the PCI network card is inserted into a PCI slot, has no problem in the supply of electricity, which provided for its cooling, it is even better than the other two cards. Compared to thePCMCIA and PCI network adapter, power adapter USB wireless network is not so stable, and is also poor heat dissipation.

Price

To start with the same brand, similar functions and close to the date, a USB wireless network card is relatively expensive and the price of a PCI wireless card and a network PCMCIA card is basically the same.
