3What is Convergence or IP Communications?
- Integrates voice, video, and data on one single
IP network - Drive down the costs by consolidation
- Enhances student and faculty satisfaction by
producing a collaborative environment - Includes IP Telephony, Video-on Demand, Video
Conferencing, Wireless, and IP Surveillance
4What is Driving Convergence?
- NCLBA
- More students, more resources, and the need for
better collaboration between students, teachers,
and parents - Safety
5Voice Infrastructure
6Why and When to Implement IPT?
- New Building Project
- Phones in the Classroom
- Improved communication with parents, students,
teachers and administrators - Enhancements of 911
- Mobile Phones
7Benefits of IPT
- Reduction in Equipment and Maintenance Costs
- Reduction in Network Administrative Costs
- Reduction in Network Carrier Costs
- Enhances Communication
8IP Telephony Components
- Network Infrastructure handles IP traffic
- Gateway Connectivity to the PSTN
- Communication Server Call Server provides
call processing services - IP Phones
- Application Server provides voice, video, or
data services from a central location on a voice
network (i.e. multimedia, voicemail, unified
messaging)
9What are the benefits of Unified Messaging?
- Improved collaboration between faculty and
students - Integrates voicemail with email
- Access voicemail from mail client
- Access email from voicemail box
- Respond to voice mail messages from email for
quicker response - Calendaring features of Outlook
10Examples of XML Applications
- I.Q. for Education Student attendance,
student/teacher locator, Rolodex, student
medical, classroom participation, lunch menus,
announcements (Sentinel) - PhoneTop K-12 Attendance, Hall Passes,
Faculty/Student Photos, Teacher login/logout of
classrooms, etc. (AAC Associates) - Time Student Attendance Attendance,
notification of truancy to Main Office or email
to parents, contact info for parents for
emergency purposes (Netiraone)
11Video Infrastructures
12Why Implement IP Video
- Enhance curriculum
- Professional Development
- Administrative Communications
13Types of Video
- Primarily, there are two types of video
- Video Streaming
- Real-time video
- Multicast
- For Broadcasting, Video Conferencing, and IP
Surveillance - Video on Demand
- Non real-time video
- Unicast
- For Archived video
14Benefits of IP Video
- Broadcasting
- Real-time events to the community
- Instruction to remote students
- Distance Learning
- IP Surveillance
- Increases security coverage
- May be viewed by Police Station providing
increased security - Help ensure student/teacher safety
- Help prevent property/theft vandalism
- Video-on-Demand
- Archived video can be viewed at different times
and rates by multiple classrooms - Scheduled in advance
15Components of Video-Over-IP Network
- Communication Server controls transmission of
video streams over the network, including
source/destination - Gateway Connectivity to the video source
- Multimedia Server serves the video streams
- Core switches and routers
- IP Cameras
16Wireless Infrastructure
17Why Implement Wireless?
- Most Obvious Reasons
- Extend Network Areas
- Provide for Mobility (Laptops and PDAs)
- Advancements
- Convergence
- Wireless IP Phones
- Radio Communication
- Emergency Service in Police Vehicles
18Current Wireless Technology
- 802.11b The original WiFi
- Ratified in September 1999
- 2.4GHz Frequency (DSSS)
- Up to 11Mbps data rate
- FCC allows 11 channels in the US
- Only three Non-overlapping channels
- Channels 1, 6 and 11
- Shared Network (Equivalent to a Hub)
- Widely available and inexpensive
- Up to 150 foot range from Access Point at 11Mbps
19Current Wireless Technology (Cont.)
- 802.11a Also known as WiFi5
- Ratified in September 1999
- 5GHz Frequency (OFDM)
- Up to 54Mbps data rate
- FCC allows 8 Indoor channels in the US
- Four Non-overlapping channels
- Channels 1, 3, 5 and 8
- Shared Network (Equivalent to a Hub)
- Slightly more expensive than 802.11b
- Becoming more widely accepted especially in
external applications like Wireless Bridging - Up to 45 foot range from Access Point at 54Mbps
20Current Wireless Technology (Cont.)
