For a twelve month period a small area of approximately 800 square feet need internet access with a wireless AP (least important), and a router with a few 10/100 ethernet connections.
The building which houses this space is only wired for [a certain provider's] service which could be used, however I am lead to seek an answer here to this question due to what I consider a very unfair price for said provider's service (sticking it to the man?) and also since my network knowledge could use a refresh.
The considerations are: a) the building has many wifi networks that are within signal range of the 800sqft. space. From my research such networks could be used by obtaining a "bridge" device or using a router that has the capability to bridge (re. Dlink DAP-1522). Said device could once configured provide wired ethernet access. The speed and reliability of these networks in the building are unknown, and access to them would be accomplished by finding one owner willing to share access ($ is available to pay them in return).
b) 3g/4g is in the area. The following is how I assume one would use this inside a building: get a 4g modem device. This device would accept the sim card, and then provide Ethernet out just like a regular cable/dsl model does. The Ethernet out is then put to a router.
c) the price for the building's only network provider is $66usd + 15% tax per month. To connect initially the service there is a fee of $199. The downstream is 24mbps and upstream is *3*mbps.
d) the down/up speed for this space need only be sufficient to allow google voice calls, skype calls, and youtube streaming for two or three (at the most) computers. Thus the question is, which of these methods would be most sensible/economical given the conditions, or what other method exists for accomplishing this objective?
e) To clarify, this is not for business use but personal use so if for example, using 3g/4g is sometimes unreliable (I don't know this, but perhaps it is) then such is not a reason not to choose it.
f) an unlimited 4g plan is available in this area for 70$/mnth.
