Impact of Coverage on Data
Throughput
“Digital cellular technology, however, runs at optimal
capacity when there is a strong radio signal. Often when
a social worker is in rural areas or inside a building the
data transmission process can be significantly slowed
down…”

Impact of Hot Spot Locations on
Productivity
“Mr. Corporate Security Guard, the reason I am parked
outside the office on Saturday is to reach the high-speed
wireless access point in the building, because, sir, the
office is closer to my home than Starbucks….”

Wireless Remote Accountability
• How it works …
— Digitized location information is sent
wirelessly to another mobile device or
monitoring center
— Phone may allow owner to make or receive
calls, indicate status, emergency alert,
etc.
— Device can automatically monitor if owner
leaves or enters designated areas
— The phone’s camera can be used to
transmit visual verification of surroundings
with timestamp
• The opportunity …
— Fewer resources required to enable
accurately-recorded check-ins for those
receiving services
— Can be combined with biometric or digital-
output diagnostic devices

Wireless Authorized Transaction
• How it works …
— RF ID works in conjunction with a mobile
device
— Instant payment to the provider like a credit
card
— Expense tracking activated via wireless
network
— Control user’s spending habits via wireless
authorization
— User-controlled PIN for security
• The opportunity …
— Fewer resources involved in service
delivery, payments and reimbursements
— Service providers more willing to participate
— Promotes responsible use of money

Personal Area Network (PAN)
Wireless Accessories
• How it works …
— Carry on a normal voice conversation
on a mobile phone in noisy
environments
— Microphone/speaker are located on the
ear and phone is out of sight
— Dialing is voice-activated
• The opportunity …
— Improved transmitted voice quality in
noisy environments
— Hands-free operation
— Discreet
