| | WIRELESS LAN GLOSSARY |
 | | Examples of WLAN technologies are IEEE 802.11b, OpenAir, HomeRF, and HiperLAN2. | | | On a network, a socket is the endpoint for exchanging data between computers, and the socket address (the IP address plus a port number) identifies a single, unique network process. | | | The protocol software computes a checksum by taking the sum of the integer values of part of the data in a packet and then appending this sum to the packet when transmitting. |

Oliver Rist is a senior contributing editor at InfoWorld. | | | Before running all of our quantifiable metrics, we also ran both vendors through a more subjective ringer involving the two other areas where WLAN switch architecture is supposed to dominate thick APs: deployment and ongoing management. |

| | CommsDesign - Crafting a Custom Viterbi Decoder for WLAN Designs |
| | The optimum method of quantizating the signal is to represent it symmetrically about the null value (the value exactly half way between a full one and a full zero), so there are equal numbers of levels representing 1s and 0s. | | | In general, the Viterbi coding scheme is one of the most popular approaches for handling errors in WLAN architectures. | | | The effect of this approach is that the path errors are compared more faithfully, resulting in more informed decisions. |
