Wireless LAN or WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and transmit data among nodes. It is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN within a building or campus. Typical bit-rates for current wireless devices are 11Mbps and 54Mbps. Wireless LANs can be formed simply by equipping PC's with wireless NICs.

A wireless LAN, SeneNET, is a network that allows access to the Seneca College network and Internet without the need of any wired connections. Wireless network information is transmitted over radio frequencies to connect laptops or PDAs to an Ethernet LAN. SeneNET wireless network is based on the IEEE 802.11b standard.

No, both Bluetooth and WLAN can co-exist. Since Bluetooth devices use Frequency Hopping and most WLANs use Direct Sequence Spreading techniques they each appear as background noise to the other and should not cause any perceivable performance issues.

The list of devices currently in our active Wireless LAN Consortium interoperability test bed is posted on our Wireless LAN Consortium Test Bed page.

Installation includes configuring the wireless transceiver. zNET will provide you with the DNS, IP address, server information, along with configuration instructions, for your desktop computer(s). In most cases, customers configure those devices themselves. If your situation is a special case, we have network consultants to whom we can refer you.

If your friend/acquaintance connects to the internet via cablecom, notification will be sent automatically. Correct authentication was already previously required if your friend/acquaintance connected via a third-party provider (e.g. ADSL), regardless of whether it was to cablecom or another ISP. Thus, changes are not necessary. This is only a temporary phenomenon and only possible in the transitional phase. Once cablecom makes the permanent switchover this will no longer be possible.

The Sarantel antenna can be installed within millimeters of other antennas without negative effects due to its reduction in environmental effects. These include crossover from electronic noise within the circuitry, electrostatic energy and magnetic crossover from radio signals. The debate by medical experts on emissions affecting health will continue. By designing mobile products with lower SARs, companies are able to offer their customers a choice.

If you have a device other than a computer that uses the network, please email compreg@wellesley.edu for assistance. These special network devices must be registered with help from IS staff. No. The computer registration system does not change any settings on your computer or install software. It simply creates a record in a secure database with your FirstClass User ID and network card ID number, along with the contact information you provide on the form.

Wireless LANs generally do not provide the reliability or the bandwidth required to support high quality video streams such as those provided by the Kaleidescape Server. The burst data rate for a DVD data stream can reach 11 megabits per second, which exceeds the practical capacity of 802.11a and 802.11b, and even some configurations of 802.11g. (However, we have received reports from customers that are successfully using 802.11g to connect a Kaleidescape Player to the Server.

The number of sensors required for wireless lan varies accordance with the wlan environment. Obstacles such as concrete walls and metal supports will decrease the RF Spectrum Coverage.

To connect to the ACEnet, Wireless network (WLAN) or Hall Network, you must first register your network card by visiting the HKU Portal at http://hkuportal.hku.hk => Services => Computer Centre Services => Register Network Card.

Sometimes, cards are not correctly recognized by the computer. Check Windows [Device Manager] to make sure your card has been recognized. If the Network Adapter is indicated with [?] in [Device Manager], wireless LAN card installation is not complete. See the User’s Manual of your card and re- Click [Start] → [Control Panel] → [Performance and Maintenance] → [System]. This will bring up the [System Properties] dialog box. Click [Device Manager] in the [Hardware] tab.

Limit the number of DHCP addresses to the number of wireless access points that you will be using. Optionally, set static IP addresses, set to non-standard network blocks. Consider using VPN, SSL, Firewalls, RADIUS, Kerberos or other access control, or end-to-end encryption. Most of these can be integrated into your 802.11b appliance.

The campus wireless network can handle hundreds of users logged in at any one time, but the more active users, the slower the network becomes. On average, one access point can handle approximately 30 users without a noticeable degradation in performance.
