2. Hardware
To make use of this service you will need a
wireless network client
adaptor. This component may take a number of forms depending on the
age and type of your computing device. Typically it will be one of the
following:
- If you have a new laptop computer, there is a good chance it came
supplied with a wireless adaptor fitted within the body. Look for an
Intel® Centrino sticker or consult your hardware
documentation. - Older or more compact or inexpensive laptops may require a wireless
adaptor card that is purchased separately and plugs into an available
PCMCIA card slot. - Some PDA's have a
Compact Flash (CF) slot to which a
wireless adaptor card may be connected. - Newer PDA's may also come with wireless adaptors fitted within their
bodies.
To help guide your purchase there may be some logos or codes on poduct
packaging that identify supported standards. The following table indicates
those supported by our service together with a brief explanation:
| Identifier | Meaning |
|---|
| The
WiFi Alliance is a consortium of vendors that guarantee
hardware compatibilty. We recommend that you purchase a product with this
logo |
802.11b | The most common standard for
wireless, providing data speeds of upto 11Mbits per second |
802.11g | A newer standard that uses the
same radio frequencies as 802.11b but provides faster data rates of upto
54Mbits per second (compared to, say, half a Mbit for domestic broadband or
100Mbits at your desktop) |
802.11a | A less common standard that
also runs at 54Mbits but using less crowded radio frequencies |
We have tested the following client adaptors, and found them each to work
successfully:
| Logo | Manufacturer |
|---|
| Intel Centrino |
| Cisco Aironet |
| Apple Airport |
| Symbol Wireless Networker |
We have also tested the following hardware platforms, and found them each to
work successfully:
- Toshiba Satellite Pro Intel Pentium 4 (laptop)
- Apple G3 iBook (laptop)
- Apple G4 iBook (laptop)
- Sharp Zaurus SL-5500 (PDA)
It must be said that wireless networking is a technology with many
competing standards from different vendors, and is not guaranteed
that a service will be supported across all devices and operating systems. We
have tried to make the Oxford service as widely accessible as possible. Please
