CABLE

    * Active USB extension cable, assures good signal quality to meet USB specification
    * Built-in signal booster (repeater)
    * Ideal cable to connect remote printers, scanners and etc.
    * 5-meter (16.5-feet) cables can be cascaded to extend the distance.
    * Type A male to type A female
    * Acts like a single port hub
    * USB Bus powered
    * USB 2.0 Compliant
    * Works with both low and high speed devices
    * Extend up to 25m (serially connecting up to 5 segments)
    * Supports WIN98/2000/XP Mac OS V9.0 or higher

Active extension USB 2.0 cable (as opposed to passive USB cables) is an active device with a built-in signal repeater. The USB signals are buffered to assure signal quality and to meet USB electrical and timing specs.

One of the biggest obstacles encountered in planning a wire run is the signal limitation of USB devices. Using passive cables for the purpose of extension will result in signal errors and is not recommended.  Passive USB cables have a maximum guaranteed length of 16 feet; ACTIVE extension cables are required to extend beyond 16 feet, essentially retaining all signal strength.

These M/F extension cables feature a booster-box on the end, and when strung together, can achieve a maximum length of 80 feet. These USB 2.0 compliant cables support data transfer rates up to 480Mbps and are fully backward compatible with both low and high-speed USB v1.1 devices. The USB extension cable acts as a USB hub and buffers all downstream and upstream data traffic. High speed, full-speed and low-speed devices will function equally well with the USB extension cable.


802.11b vs 802.11g

If you are trying to reach a distant or weak network signal for internet access:
  802.11b will provide better range/distance than 802.11g
  802.11b provides plenty of bandwidth for internet access at broadband-speed
  For longer-distance links, your wireless card/USB adapter will automatically select a lower-bandwidth data-rate:  Therefore it will automatically select 802.11b mode

Many people assume that 802.11g mode is better than 802.11b for their situation.  However, If range matters more than bandwidth requirements, 802.11b has better range and penetration and its throughput will degrade less than 802.11g at the same distance. If you are using the connection primarily for web-surfing and email access, your bandwidth bottleneck is the speed and quality of the host internet connection - not the "b" bandwidth.   If you are using the connection for local-area networking that requires a lot of bandwidth (file-sharing, streaming media on the local network), then you should use 802.11g mode or 802.11n mode.

An 802.11g access point will support clients operating in either 802.11b or 802.11g mode. Similarly, a laptop with an 802.11g card is able to access 802.11b access points as well as 802.11g access points.  802.11b and g clients automatically select the best data rate, based on available signal strength.  For longer distance links, a lower data-rate will be selected.  Therefore, for longer distance links or links that have some obstruction (no clear line of sight), there is no added benefit in having an 802.11g client as compared to an 802.11b client.  The selected data rate will be either 1, 2, 5.5 or 11 Mbps:  The rate selected is influenced by signal-strength factors such as the distance between the access point and client-radio, and the degree of openness of the line-of-sight, versus obstruction of the line-of-sight by any type of object.  For the longest-distance links, the lowest data rate will be selected, and for the short-distance links with no obstructions, the highest data rate will be  selected.

Many major WiFi implementations, such as municipality-wide and in apartment complexes, use 802.11b in network implementations:   The reasons are:
1.  G requires use of three different channels simultaneously, and the network implementation may have a constraint to not lock up three channels
2.  B is fast enough and lower-cost (with actual throughput of 1 to 6 Mbps exceeding the Internet connection speed).
3.  Any B client on an 802.11g network will force the access point to operate in B mode, so that the bandwidth advantages of G are nullified.

802.11b equipment can transmit data-frames at rates up to 11 Mbps, and the network protocol overhead reduces the actual/net data-transmission rate to 5-6 Mbps.  

Finally, a laptop's battery-charge will last longer with 802.11b, because it consumes less power than either 802.11g or 802.11a.
