For a Fast and Reliable Wi-Fi – Access Point/Client/Repeater of Signamax 065-1755 Brand

Significant majority of offices today are covered by default with Wi-Fi signal. This advantage will be valued the most by mobile users utilizing notebooks because they will not have to struggle with annoying cables while working.
The band of 2.4GHz is mostly utilized together with the 802.11b/g standard. It is also being often interfered with intensive usage of not only wireless technologies in general, but also by using Bluetooth technologies for various wireless devices like mice, keyboards, etc. Despite the theoretically high transfer speeds, in practice the maximum data transfer rates usually fall into the range between 6Mbit/s to 12Mbit/s. One of the potential solutions is technology of 802.11a working in the frequency band of 5GHz, which is currently not subject to such intensive usage and thereby achieving common transfer speeds around 18Mbit/s is more realistic. Thereto we can expect higher inhibition from the environment during the twice as high frequency, thus the lesser reach end penetration through for example the walls or doors. However, in practice, such differences have not shown as significant.

Elegant, even though Packed with All Kinds of Functionality
The Access Point design is of the elegant black color (also white color is available), the front part features LED diodes indicating the status, and the rear part features two connectors for external antennas, power connector, and one RJ-45 connector for Ethernet. The biggest advantage is however the feature, which you will not be able to see at first: the two integrated radio interfaces allowing usage of the 2.4GHz band @ 802.11b/g and 5GHz band @ 802.11a. Both antennas can be assigned separately to each frequency or they can be utilized for reception of the specially diversified signal, which is very useful in cases of signal interference.
Control and configuration of the device is done via web interface. For LAN, the default IP Address is set, it is therefore necessary to establish the direct connection with a computer. The initial configuration is naturally utilizable for the services of DHCP server within your network while the IP Address would be assigned to your Access Point automatically. The initial configuration of the fixed IP Address will be valued especially when you plan on using no services of the DHCP server.
Nevertheless, most interesting are the possibilities of the wireless part. In the basic configuration, you select whether the radio would be turned on or turned off, and furthermore you select the operating mode (for 802.11 b/g), SSID, and the channel. Very important is also configuration of the mode within which the wireless device would be working. You will most likely use configuration of the Access Point for both frequency bands of 2.4GHz and 5GHz. It can be also configured as the repeater, bridge or wireless client.

Utilization of both radio types brings great advantage due to compatibility because you will be also able to connect Signamax 065-1755 to the devices designated for 2.4GHz, whereat utilizing, where applicable, the benefits of the less-interfered band of 5GHz and higher transfer speeds. If your notebook features the integrated Wi-Fi card for 802.11a @ frequency of 5GHz, you will be able to utilize for instance the excellent 065-1752 Signamax Wireless 5GHz USB Dongle, 802.11a/b/g. In addition, the options of security are very good. You can use WEP (64bit and 128bit), or alternatively WPA (TKIP and AES). In the case of need, the Signamax 065-1755 knows how to cooperate during authentication with the RADIUS server. For purposes of access limitations, you can also use the filtering of wireless clients per their MAC Addresses. The foregone conclusion is the option of switching between authentications modes of the open system and the shared-key closed system.

Performance Management? No Problem at All!
With regard to advanced configurations, you will surely value the option to manage performance at several levels: maximum, 50% (-3dB), 25% (-6dB), 12.5% (-9dB), and minimum. We always recommend setting the transmission performance to the lowest possible value in order to provide the still reliable transfer via high speeds. Unnecessarily high performance might cause significant interference. Interference could be also created because of the multipath signal distribution or because of the interference from surrounding environment. Due to that, the "pockets" with weaker signal are created, and in extreme cases, no signal would be detected at all. This effect is called the "leak". Nevertheless, you do not have to worry about experiencing such effect with Signamax 065-1755. The most powerful weapon for eliminating the leaks is the technology of the spatially diverse reception and transmission, where two antennas close to each other are being utilized for the identical signal. Therefore, we recommend setting the device as to have both antennas configured for the diverse reception. Another option is to assign each antenna to the different frequency. However, this option is only for the cases when you would like to utilize the device for creation of the directional connections.

5 GHz is Faster
In the end, you will surely be interested in the differences of the transfer speeds and the signal reaches when comparing the technology of 802.11a @ 5GHz with the technology of 802.11g @ 2,4GHz. The best would be to perform the testing in laboratory conditions. However, such testing would be more suitable for comparisons of the technologies as such. We are rather interested in the benefits of utilizing the non-interfered band of 5GHz as opposed to the busy band of 2.4GHz. So what are the results of the tests? The reach of 802.11a @ 5GHz is really slightly lower than the reach of 802.11g @ 2,4GHz. Some signal is lost during penetrations through walls, but the loss is minimal. Whereat both technologies can theoretically achieve the transfer speeds of up to 54Mbit/s, in reality the 802.11a standard will provide excellent maximum speeds of 18.5Mbit/s. The 802.11g standard offers virtually the same maximum transfer speeds; however, due to interference, you would rather expect the speeds in the ballpark figure of 10Mbit/s.

Excellent Choice for Great Price
If you plan on utilizing the benefits of 5GHz band and simultaneously on keeping the signal coverage of 2.4GHz, the Signamax 065-1755 is the definite choice for you. Moreover, you can buy it for the same price as the regular 2.4GHz Access Points. From the financial point of view, you can take the 5GHz band as free bonus!
