7. Review the preliminary system proposal recommended by the sales
group with the customer. Adjust the proposal according to customer
requirements.
8. Finish planning the site as shown in "Site planning basics" on page 21.
The Apex Department Store has 300 employees working in 45 departments on
the store floor. Each employee works in only one of the departments. The
store's inventory is so large that the employees climb 27 ft (8 m) high shelving
on lateral moving ladders to reach the merchandise, which makes it impossible
for the employees to use desk telephones.
Employees constantly answer a speaker broadcast system to know what
merchandise to get. If the employees on the ladders do not understand the
message, they climb down the ladder and walk to the nearest phone to find out
what was said. Outside calls are also discouraged because of the time spent
locating an available phone.
Twelve employees work the front counter taking orders from customers. These
employees often wait for their turn to call out the orders on the speaker
broadcast system.
Your customer wants to give each of the store's 300 employees who climb the
ladders a portable telephone and remove the speaker broadcast system. The
sales group recommends a Companion (C200) system.
Since none of the users have an office with a desk, you plan the coverage area
using -73 dBm. You survey the site and find that the store requires 18 cells for
full coverage. The mobility of the users is more vertical than it is horizontal.
Except in a few cases, one cell covers entire departments. This means the
users' work restricts the mobility of each user to one of the cells.
