Mobility Challenge
• Challenge #1: User Experience:
– Explosion of wireless devices drives wireless access needs
and issues
– Need for video support for distance learning, rich digital
content and professional development
– Bandwidth availability: Wireless is a shared medium
– Roaming: Tablets and iPads introduce roaming and
Mobility Challenge
• Challenge #2: Security:
– Need for a secure connection and provisioning for right
access
– Policy Assignment: who is the user, what device, where
and when is access permitted
– Off-premise access: How do you protect Administrative
data when device is off the premise?
– Capacity planning
– Troubleshooting of unmanaged devices
– Guest Access

BYOD Considerations at a Glance
• Scalability: How can you accommodate new devices and applications on your network?
• Security: How can you determine who, what, when, where, how, and how many users and devices access your network?
• Manageability: How can you manage users and devices, and ensure
compliance to polices no matter how one is connected or where they are located on your network?
• Simplicity: Is there a way to handle these issues that doesn’t involve new layers of complexity?
• Budget: How can your systems handle these demands while
controlling costs?
• Accountability: School systems at all levels are being held to extremely high standards. It’s critical to show improvements in student outcomes while justifying all technology purchases in terms of how they help the educational experience and increase efficiency.
Key Components for BYOD/One-to-One Planning
• Wireless Connectivity
• Security
• Mobile Device Management
• Network switching
– Gigabit Ethernet for Access Points – Multicast to support video streaming
• Bandwidth
– How much Internet Bandwidth is needed? Important to plan for

Wireless Technologies – Traditional WLANs
• Traditional building-wide wireless design focused on pervasive
coverage:
– Access Points in Hallways
– Access Points in Key Areas: Cafeteria, Gym, Library
• Typically mix of Access Point types and limited management
• May have used older cabling for APs
• This traditional design is limited for high-density
requirements and may not provide the scalability needed for
a successful One-to-One Computing/BYOD deployment
Wireless Technologies – High-Density
• While there have been great advanced made in speed and
ease of implementation of wireless, basic nature of radio
frequency is the same.
• Increasing the number of users in a small space is a challenge.
– Access Points closer together and usually in every classroom – Management is key
• New BYOD Initiatives require redesign:
– Determine how much bandwidth each user will require
– Calculate aggregate throughout for coverage area (usually by classroom)
– Inventory existing wireless equipment and potential device types to determine potential cell coverage

Wireless Technologies – Access Points
• Wireless Access Points:
– 802.11n provides best throughput and efficiency today in
high-density deployment (permits more users or higher
speeds to be realized on same channel)
• Two types: fixed internal antenna and external antenna options
– External antennas good for directional coverage and stronger signal
– Support for multiple protocols (most WLANs have mixture)
– Support for dual-band optimization (forces clients capable
Wireless Technologies - Management
• Wireless LAN Controller (Management):
– Provides centralized management of Access Points for configuration, troubleshooting and maintenance
• Automates wireless configuration and management functions
10
Wireless Technologies - Security
• Security is a key concern in a BYOD deployment
• Challenges:
– How do you limit network security threats caused by users accessing with mobile devices?
– How do you determine who, what, where, how and how many access your network?
• For BYOD, need solution that provides for
authentication, authorization and accounting
Wireless Technologies –
Security & CIPA Compliance
• Incorporate solutions such as NAC/802.1x that
performs the following:
– User has device (could be personal or school-issued) – User connects to wireless network
– Device is finger-printed, scanned and appropriate policy is determined
– Policy is issued and device securely connects to network
• Due to CIPA compliancy, devices will need to
be configured to access Internet through
12
Internet Bandwidth Considerations
• Successful BYOD hinges on how the devices impact Internet
performance, reliability and stability.
• Evaluate needs for increased Internet Bandwidth and plan in
accordance to BYOD deployment schedule (i.e. as more
devices are added, more bandwidth will be required)
– Plan a strategy for shaping and managing Internet access based on protocol, application type or defined policies
– Router and Firewall would be scalable to support increased bandwidth – Content Filtering requirements in order to comply with CIPA
• Start planning and budgeting now for Erate Yr17 filing
Mobile Device Management
• Successful deployment of Laptops, tablets, iPads and other
devices requires a Mobile Device Management solution
• Mobile device management (MDM) refers to any routine or
tool intended to distribute applications, data and
configuration settings to mobile devices.
• The intent of MDM is to optimize the functionality and
security, while minimizing cost and downtime.
14
Mobile Device Management
• The ideal mobile device management tool:
– Is compatible with all common handheld device operating platforms and applications (if not standardized on one platform)
– Can function through multiple service providers (important if District has multiple ISPs).
– Can deploy next-generation hardware, operating platforms and applications quickly.
– Can add or remove devices from the system as necessary to ensure optimum network efficiency and security.
Policies and CIPA Compliance
• Considerations for BYOD policy:
– Technical Requirements needed for Infrastructure (key for planning
and budgeting)
– Guidelines for Access (instruction and educational use is primary) may include:
• When it can be used • What can be used for
• Use of device on School network means subject to school’s security policies
– Procedures students must follow to gain access under BYOD policy – Be specific on what School is responsible for:
• Access to wireless for Internet Access only (CIPA compliance)
• School District not responsible for maintenance or repair of user-owned device
16
Policies and CIPA Compliance
• Mobile Device Acceptable Use Policy:
– Outlines strategy and specifies expectations of users
– Applies to any mobile hardware used to access school’s network whether owned by user or school
– Educate users on how to use mobile devices in a safe and secure manner (what is allowed and what is not)
– Keep signed copies with Internet AUP
• CIPA Compliance: Critical for Erate funding and must be
Recap – Steps to Success
Planning is key for a successful BYOD or One-to-One deployment – perform an Assessment. Ask yourself:
• Is your infrastructure prepared?
– Does your school have the proper wireless equipment? – Is there secure access for students/staff?
• Health and Safety
– Is your school prepared for when students break the code of conduct? – Are present board policies counter to what BYOD means?
– Do they ban the very devices that students are supposed to use?
• What does BYOD mean? Which devices do you need to plane for?
– Laptop? – iPad? – Tablet?
18
Recap – Steps to Success
• What about the students who cannot afford the devices?
– If schools require or encourage devices, they need a plan for those students who cannot afford them
• How will teachers receive professional development around BYOD?
– Not all staff understands how it works.
– Many teachers want to allow students to bring their own devices but they do not always understand how they handle the concept.
• Outreach to parents
– How are parents being informed that their children can BYOD? Parents need to know what their children are doing with the expensive devices they bring to school.
– What is the policy if a device gets lost or stolen? Is school like a hotel? They're not responsible for lost or stolen items?
Final Note – Planning/Budgeting
Technology acquisitions…
– Hardware: Much shorter lifespan
• Network Components cannot be limited to a 5-10 year
refresh
• User Devices becoming “disposable”
– Software: “Licensing” replaces “Purchasing”
– Services: Required “bandwidth” increasing annually with user
and device population
…need to move from Capital Planning to
Operational Budgets!
