I have a project with a customer and a remote campus. The remote campus currently consists of two cottages (35?x147?) separated by ~800ft with clear line-of-site. The first cottage has an existing DSL Internet connection with D-Link wireless router and provides wired\wireless Internet to the tenants in that cottage. I plan to replace the D-Link with a Cisco 877 ADSL or Cisco 877W ADSL\Wireless router to provide a simple GRE\VPN tunnel back to their main campus. I already use the same configuration to tunnel another remote branch back to the main campus T1 for Internet content control with a Barracuda.
I need to connect the 2nd cottage to the 1st via a wireless bridge (Aironet 1310) at the remote campus so I can backhaul all the Internet traffic back to the main campus via the DSL Internet\VPN tunnel. At both cottages I will need to provide both wired and wireless connectivity inside. It's a bit overkill for the range but I plan to use a pair of Cisco Yagi directional antennas with the Aironet 1310-RP-TNC instead of the ones with integrated antennas to be a little more versatile in any future expansion of the remote campus.
The bldg-to-bldg configuration seems relative easy, configuring the 1st cottage with Internet\VPN DSL and Aironet1310 as a root bridge and the 2nd cottage as a non-root bridge. The 1st cottage will already have a switch with the Cisco877/877W for the wired connectivity, so I?ll just need to add a switch to the 2nd cottage.
I need a little help understanding the wireless connectivity inside the cottages. I understand that the Aironet1310 bridge could act as a local AP for the cottage, but since the antennas are outside Yagi directional then I think the inside coverage would be very limited. So could I change the Aironet 1310 bridge antennas to outside omni-directional to provide adequate bldg-to-bldg (~800ft) link and inside bldg (35?x147?) coverage? Or, should I use the wireless capability of the 877W (ADSL) router at the 1st cottage and a 2nd 871W(Ethernet) router or AP at the 2nd cottage for inside coverage?
I would like to keep the configuration simple with a Cisco 877 Internet\VPN to connect the main campus and a pair of Cisco Aironet 1310?s for the wireless bridge between the two cottages. I'm just not sure on the wireless inside the cottages. The tenants will be using laptops with integrated wireless or wired desktops.
I appreciate any help,
