I am overseas and have recently adopted a satellite internet system. I have two distinct issues with the system.
Situation: The network is intended to support 150 wireless users. The users are in three distinct areas.(b1, b2, and b3). b1 is the tallest building and thus supports the satellite. b2 is 120 meters from b1. b3 is a group of 4 buildings spaced within a 75 meter square and is approx. 75 meters to its center from b2.
The satellite contract reads 4.0 mbs down/1.0 mbs up with a 2/1 contention ratio.
Currently there are two networks defined NET1 and NET2.
Current hardware is as follows:
Satellite and Nera Satlink 1000 - b1
Linksys WTR54GX4 - acting as an access point in b1
Linksys WTR54GS V3 - acting as an access point in b1
Linksys WTR54G V5 - b1 this router defines NET1
Linksys WAP54G - located in b1 connected to a DLink 10 dBi panel antenna oriented towards b2
Linksys WRT54G V2.2 - This router defines NET2 connected to a DLink 10 dBi panel antenna oriented towards b3
Linksys WAP54G - configured as a bridge
1. Network stability - The network is inherently weak between the bridge. I believe this issue to be because of limited line of sight to the antenna attached to the bridge and the panel antenna broadcasting from b1. Additionally we are seeing problems between the second panel antenna and the access points in b3 due to the same issue.
2. Bandwidth - the contract reads that contention ratio is 2/1. However, we are not seeing speeds I believe the issue is that with the current hardware (specifically the routers) we are only able to have 19 concurrent wireless users per router. This is particularly an issue in the b2 to b3 configuration because we have one router handling over 100 users.
I am a programmer and not a network administrator. Thus my knowledge is very basic. Please feel free to ask questions and clarify this issue. I am looking for someone who has had experience in either developing a wireless solution for 150+ users and/or someone that has experience in developing wireless access over a 300 meter linear spread.
Thank you for your help.
