• Do I need to have an account with a WiFi service provider to use wireless?
  • What distance can I get with my internal wireless card in my laptop?
    Although the range of the internal wireless card will vary among manufacturers, you can expect to get anywhere from 25 feet to 100 feet away from an access point, or hotspot, before loosing your connection.   Although manufacturers will inflate the distance they perceive their products communicating at, these estimates are not practical, and are usually always wrong.  At GNS Communications, you can expect to receive a real life estimate of what our recommended products will communicate at.  A common fix to the internal wireless card is to upgrade to a PCMCIA card, like the ZyXel B-101 card.
  • What PCMCIA card do you recommend for my laptop?
    For the best coverage around the house or office, or while logging into hotspots on the road, you want to go with a card that allows for the addition of a high gain antenna.  There are a few different cards out there that allow this, but we recommend using the ZyXel 802.11b card.  This card allows a high gain antenna to be connected to it and also has excellent range with or without an upgraded antenna.  Contact us for more info.
  • Can I mix wireless equipment from different vendors?
    If you are using 802.11b, or 802.11g equipment, you are able to mix different manufacturers products and still get a connection.Although the majority of wireless equipment are inter operable, we recommend verification as teh standards are fairly recent.Some applications do require the use of similar devices in order to be supported. Most of these devices are Power-Over-Ethernet adapters, and bridging kits. Most PCMCIA cards, PCI cards, and other client devices will talk to whatever type access point is available.

  • What is a Bridge Kit?
  • How do I setup a building to building link between 2 locations?
    If you are trying to connect 2 locations wirelessly, all you will need is two high gain antennas, 2 wireless Access Points, and 2 sets of extended coax cable. You will also need lightning arrestors if the antennas are to be mounted on the roof. This type of setup is known as a bridge kit, and can connect two locations up to 50 miles apart depending on the device used. For more information, please visit our bridge-kit page or contact us today.
  • How long do I have, to run an antenna cable to my device?
    Each wireless device has a certain power output. Most of the wireless access points have a power output of about 100mw. Client devices on the other hand usually have a power output of about 80 to 100mw. Depending on the power output of your device, and depending on the gain of your antenna, and the type of cable being used, is how you determine the length of coax cable you should be running between your antenna and your wireless device.  

    We use two types of cable, LMR-195, and LMR-400. LMR-400 is usually meant for outdoor cable runs and has a lower db loss per foot.  LMR-195 is meant for indoor use and has a higher db loss per foot. The longer the coax cable you use, the lower the gain or strength your antenna will be.
