We are required to evaluate the number of access points required
and the placements of those access points in a Ubiquitous Office
(UO). Here we would be needing four access points since four Aps
will be able to serve the entire office of 150x150. The Aps have to
be placed 50 feet away from each other in the middle four corners
of the office forming a square of 150x150 sq feet.
- 1000Base-T uses Ethernet cards
- It uses copper wires for communication
- The other name for this standard is IEEE 802.3 ab
- It is of the magnitude of Gigabits
- The maximum length that can be supported a single segment is
100 meters
- It can transmit up to 1000 Mega Bits Per Second and hence the
name 1000 Base T
- The base is restricted to Ethernet signals only
- It uses Category 5 twisted pairs without shielding
- Our building inner area is 150*150 = 22,500 square feet or
45.72*45.72=2090.32 square meters (sq.mr.) approximately (2090.3184
square meters rounded to 2090.32 sq. mr.)
- Area of the office space = 2090.32 square meters =
22,500 square feet.
- A single access point can support between 1600 to 4900 square
feet (sq. ft.) depending up on the wall thickness, the gain boost
by the antenna, amount of power settings made etc – we are having
dry walls
- Factors like The cement or brick walls used in the civil
engineering construction, amount of traffic density all contributes
to the coverage by a single access point
- hence these factors will affect the number of access points we
would need
- we would need between 5 to 14 access points for 22,500 square
feet
- But if we buy the 802.11 enterprise grade wireless LAN access
points, we can vover this area with just between 4 to 7 access
points as they have more coverage capacity of between 4900 square
feet to 9900 square feet per access point
- Data support can be provided up to 20 to 30 clients per access
point
- but voice will reduce it to 10 to 15 clients per access
point
