| 231793 | 2004-04-24 11:29:00 | Greetings, Im possibly doing a job for a client who wants Wireless gear setup between two buildings. The rooms are likely 50m away and will probably have two concrete walls between them. They're going to want an Adsl router with wireless connectivity too. They have laptops that use 802.11g, which IIRC is able to switch between 802.11a or b networks?! Correct? What router would be best? How fast is it likely to be (Anything 1mbps or over should suffice, as long as there are no lost packets... I have til 9am tomorrow to find a router and email them the details. Cheers Chill. |

| 231794 | 2004-04-24 12:19:00 | Hi Chill, have a look at some of the Linksys routers/access points. They're an off-shoot of Cisco now aren't they? Not sure on the ranges of those, but you might get more range by putting the routers near a window or something. |

| 231795 | 2004-04-24 12:25:00 | Well current wireless networks are said to have a max range of 100-150ft indoors. So thats 45.72m, and yours is outdoors too... | PoWa (203) | ||
| 231796 | 2004-04-24 12:26:00 | 50 metres .... + (reinforced) concrete walls .... You need a miracle, not a router. |

| 231797 | 2004-04-24 12:33:00 | 802.11g is compatible with 802.11b, but not 802.11a. I also believe there is another standard coming along soon (*sigh*). I'd suggest to find out technical details of the wireless capabilities of the routers you're looking at, such as signal strength, whether the antennae is/are moveable, etc. A signal booster might also be necessary, since it would be going through two concrete walls that are a fair distance apart (I should think that where it would fall short is after going through the second wall - it should be fine up to a certain distance for the first one). Perhaps directional antennaes would also be better suited to the job. US Robotics have some good products, such as the SureConnect 9106 (www.ascent.co.nz). |

Antennae looks like the way to go PoWa> Cheers, I'll check 'em out :-) Are there any other routers that might be good for the purpose... Bigger antennae for everybody? Chill. |

Nothing wrong with that.. on one hand you've got wimax which offers a 30mile coverage, up to 76 (ish) mbit connectivity, you dont need LOS either. On the other hand you've got 802.11.n which brings in a whole raft of features and IIRC 108mbit connectivity. .n backbones and wimax nodes sounds great to me To answer the original question: You wont need much power to do a 50m connection, you could use a bridge at either end and connect them to directional panel antennas. You wont need much gain to do 50m Perhaps you should ask on the nzwireless.org forums? |

| 231800 | 2004-04-24 22:38:00 | My office is a tin clad "Gottage" made by Skyline. I have an external antenna set up on its verandah post to communicate with the other part of the WLAN inside the house. Without the external antenna I used to have no end of trouble with dropped packets etc because the signal could not cross the tin cladding. With the external antenna I got excellent connection until some nasty neighbour introduced some interference into the ether and now my WLAN just drops connections all the time. However, the external antenna was all the go until the neighbourly interference (probably a 2.4Ghz phone or a competing WLAN). My external antenna is sited horizontally rather than vertically. For some peculiar reason it works far better that way - if you set up something like it, you may like to experiment with the orientation. My WAP is a Linksys WAP11 with a signal booster. The adapter in the house laptop used to be the matching Linksys PCMCIA adapter, but I have found that the el cheapo DSE USB adapter was better because it can be sited to get a better signal. I also thought that the PCMCIA card seemed to get very hot and towards the end of my use of it, it seemed unreliable. John |

| 231802 | 2004-04-25 02:28:00 | You should use wires, faster, just not as easy to setup up. DWNZ |
