Antenna Type and channel bandwidth #105
Comments
|
Hi,
1. Not yet. It could be implemented with wmediumd.
2. Yes, you can. I just added support to ht_capab and you can use the param
with the same name when you create APs. For example:
*ap1 = net.addAccessPoint('ap1', ssid="simplewifi", mode="n",
ht_capab="[HT40-][SHORT-GI-20][SHORT-GI-40]", channel="5")*
Please refer to hostapd.conf
<https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf> for further
information on how to configure HT. If you need support to VHT please let
me know which parameters you need to make it work.
BTW, I don't know what is the impact of this type of configuration during
data transmission (I couldn't read about it yet). Any help is welcome ;).

… Hi!
I have two important questions in order to proceed with my work:
1.
Can I choose the type of antenna? For example, a tri-sectorized one
(not omnidirectional).
2.
Can I define a channel bandwidth? I want to use a 10 MHz channel, it
is possible?
Thank you.

Alright thank you, I'll try that. Other question:

Yes, you can. If you change the channel, you change the frequency.

- And can I change the frequency ? I know that the frequency depends
on the mode, but can I define a frequency value and not use the mode ?

Yes, but I want a specific frequency, 2 GHz, and do not correspond to any channel frequency. |

Hi Inês,
Could you please let me know which wifi technology works with 2Ghz?

It is not a Wi-Fi technology, I am simulating a Mobile Network, LTE (4G). |

As probably you know, mac80211_hwsim was designed for wifi networks. If you
want to simulate 4G, you should manipulate bw, loss, latency and delay.

Alright. Those parameters are defined for each link ? Or can be defined for the network in general or for an access point ? |
|
For the network in general (by default). You can change it if you want.

Okay thank you ! |

Since you have the position of every node (node.params['position']), you
just have to use the formula for calculating the distance.

I'll take the opportunity to ask another question:
I want to do a graph with the throughput depending on the distance with
mobility, so I need to print the sta distance as she moves, so how can I
get the distance of a specific sta at any second and print it to a txt?

Hello, I just read the conversation. |

Hello,
Yes, you can do this by changing the network parameters. A new mode (4G
mode) could be created for wmediumd as well. As a consequence, the module
mac80211_hwsim could be extended as well.

… Hello, I just read the conversation.
I am wondering if it is possible to integrate 4G in mininet-wifi knowing
that mac80211_hwsim was designed for wifi networks. If it is so, how can we
do this? Could it be by simply changing the network parameters?
