What is Messaging?
 Short Messaging Service

Typical message lengths under 500 characters
 Peer to Peer

Direct messaging between devices
 Wireless “Instant” Messaging

PC to device messaging via IM Service Providers
Wireless email


Managed email on mobile device
What about Messaging Things?
 Machine to Machine

Telemetry and Telematics
 Machine to Peer

 Machine to Application

Internet Automation
 Application to Application
Why ReFLEX?
 Simulcast versus Single transmission

Better in building penetration
ReFLEX networks simulcast from multiple towers at up
to 3500 watts ERP (high power)
Cellular type networks transmit from a single tower at
60 watts ERP (low power)
Benefits of ReFLEX Simulcast
 Superior message reception due to macro
diversity
 Superior Quality of Service for message
delivery
 Largest coverage area of any land-based
wireless technology
OK, I see some benefits
 Wide-Area Coverage

Why is ReFLEX better?
 Battery Life
 Reduced battery consumption, most devices
last weeks on AA’s
 Lowest Cost to operate network

ReFLEX Cost $1’s per Covered “POP” vs. Broadband
PCS Networks Cost >$45 per Covered “POP”
 Common Protocol

Unlike Voice, ReFLEX is a Common Device Protocol
Why is ReFLEX best?
 Serious building penetration!
 Simplified retry mechanisms!
 Broadcast services!
 Economical devices!

And more manufacturer’s entering the market
 More available, reliable, timely.


Largest wireless coverage footprint
Guaranteed delivery within Network
 Double the number of subscribers vs.
one year ago!

What about other protocols?
 Carrier to Interference Ratio,

It’s suitable for voice but, it’s not suitable for robust
data.
 Simulcast advantage
 Data channels must “claw back” Quality of
Service with channel coding.
 Cellular data networks do not account for
retries necessary for perfect transmission.
I thought they might not be as good
 Voice networks tolerate high Bit Error rates.
For most data applications, the ideal Bit Error
Rate (BER) is 0. This is difficult to maintain in
a Wireless network.


High BERs will increase retries for data delivery
This adversely affects battery life and latency
characteristics.
OK, so other protocols have problems
 GSM/GPRS/EDGE/3G is not optimized for
Messaging.
 3G, In trying to be the Swiss Army knife of
mobile service suffers under uncertain time
lines. Are you willing to wait!?
 IEEE 802.11 and Bluetooth are not wide area
solutions, period.
 No common standard
Data transmission will be perfect
 The ReFLEX protocol provides data
segmentation and retransmission.
 The ReFLEX protocol enables guaranteed
delivery
ReFLEX is Messaging
 ReFLEX is optimized for wireless
messaging!
 Highly efficient queuing model.
 Cellular services will always favor voice!
People will carry two devices:
a voice and a data device
Each is designed for peak performance in
a specific field
Wireless data devices are always on
Data devices are not obtrusive
People use both simultaneously
Strategy Analytics predicts 25% of installed base of
handheld devices will be wireless enabled in year 2004.

The Simple Facts
 ReFLEX is the best choice for Wireless
Messaging
 GSM/GPRS, EDGE, 3G will not be soon
enough
 2-Way wireless messaging is the fastest
growing sector of the industry
 Wireless Messaging is worth doing right

Wireless Communications Transfer Protocol
How does this
help me?
What is WCTP?
 The preferred standard protocol for
sending & receiving messages from the
Internet
 Designed for wide range of messaging
and wireless devices, not only ReFLEXTM
 Provides an extensible architecture
 Supports transport of any type of binary
data
OK, How’s it work?

 Based on XML and HTTP transported
 It is the application interface to the
wireless network

 WCTP 1.1 is released and carriers are
actively moving toward it
Oh yeah, Version Control
Versions may be safely deprecated or declared obsolete

UAR? FLEXsuite?
What are these for?
What is FLEXsuite?
 A collection of I/O, application, &
application-enabling protocols
 A unique, recursive stack model


protocols may carry message, or
another FLEXsuite protocol
 Always used within ReFLEX networks

can be combined with WCTP for powerful,
peer-to-peer transport at application layer
What are the FLEXsuite protocols?
 Uniform Addressing & Routing (UAR)

mapping PSTN/Internet/ReFLEX networks
onto ReFLEX networks
 Data Security Identifier (DSI)

RC4 encryption
 Key Management Request Protocol (KMR)

What does UAR do for me?
 Supports, through routing & address
adaptation:



ReFLEX Peer-to-peer messaging
Wireline device to MS messaging
Wireline application server (e.g., email) to MS
 For content routing, activated at an Input Node
 For end to end routing, supported at Host
How does this get my data to my app?
 From Server:

Submits payload to Carrier via WCTP
Recipient ID: user@carrier
Sender ID: domain.com/cgi-bin/postMessage.pl
Payload: Alphanumeric/Opaque-Binary
 From Device:

Sends payload to Server via WCTP
Recipient ID: domain.com/cgi-bin/postMessage.pl
Sender ID: user@carrier
Payload: Alphanumeric/Opaque-Binary
For Example
 From Server:

Routing on device using UAR:
To:
• Port: 29
• Path: games/chess/
From:
• Port: 80
• Path: chess/
