◦ Managed Internal Broadband Services
◦ Basic Maintenance of Internal Connections

Cabling◦ Including Fiber INSIDE a building.
20 to 85%. District Level Discount only
The Category 2 budget system was created as a Five-year pilot program.
This is year 4.
There is no guarantee as to if or how Category 2 funds will be funded, allocated, and prioritized beyond FY19

2015 Ohio School Design Manual (OSDM)
Requirement added for CAT 6a cable utilized for the wireless access points to be "shielded" cable. (Ref.: 8500.1.02.C.2.b and Sections 271513 and 272133).
Updated network electronics requirements for all switch ports to be GB, POE+ and comply with current industry standard of 802.11ac. (Ref: 8500.1.02.C.3 and Section 272100 and 272133).
Dual 10 GB to the Switch Closet / Stack
Cat 6a STP for each access point
30 watts POE for EVERY Port
Non Blocking◦ Enough upstream bandwidth for every port
2017-2018
Goal 1: Ensuring schools and libraries have affordable access to sufficient high-speed broadband:◦ To help measure and set benchmarks for this goal
the FCC proposes the following.
For schools:
◦ The FCC adopts the State Education Technology Directors Association’s (SETDA) bandwidth target of 1 Gbps per 1,000 students and staff in the long term (¶34).
(SETDA defines “long-term” as 2017-18).

Just not yet.
G-Suite is now the norm
G-Suite schools use less bandwidth then other 1:1 devices
Most schools use LESS bandwidth for Testing then daily instruction
Don’t deploy 800 Chromebooks in one day.
802.11a up to 54 Mbps in 5 Ghz Band
802.11b up to 11 Mbps in 2.4 Ghz Band.
802.11g up to 54 Mbps in 2.4 Ghz Band.
802.11n up to 600 Mbps via MIMO◦ Technically supported in 2.4 Ghz.
802.11ac 3.47 Gbps via MU-MIMO ◦ Supported in 5 Ghz Band.
802.11ac Wave 2 6.93 Gbps via MU-MIMO
160 MhZ Channels are not practical in K-12◦ 160 MhZ = Only 2 possible channels
◦ 80 MhZ = 4 possible channels
◦ 40 MhZ = 9 possible channels
Due to Density issues, 40 MhZ should be the maximum planned deployment.
80 MhZ channels do not permit sufficient overlap of Wifi Channels.
◦ Recommended Bandwidth for High Density Deployment
◦ 40 MHZ = 9 channels
About 125 Mbps/AP Max (Practical AC Wave 1)
About 240 Mbps / AP Max (Practical Wave 2)
240 / 4.3 = 55 Devices per AP
Low cost devices don’t have high Cost WiFi Chips
The average portable device is in use for 3-5 years
◦ Or Longer…..
How long will you have your Wireless Deployed?
Cat 2 Funding may be disappearing
What is your average/Max Teacher Class size?
What is your Standard 1:1 Device?
If Cat 5e is already run, running new cables to your AP’s is not likely to have a positive impact for 802.11ac.
If running NEW cables, Cat 6a STP is worth the investment.
◦ STP helps shield the Data Path from the RF.
◦ Reduces Errors in data transmission
OM1/2
10GBase-LRM will reach up to 220m over standard multimode fiber, using a single laser operating at 1310nm.
A Mode Conditioning patch cable is recommended.
Without Mode Conditioning, 10 GB will link, but may not be stable.
Orange patch cables may not mean 62.5 micron (OM1/OM2 Fiber) is installed.
Check the Jacket Labeling to confirm.
Total Length is Critical
Quality of Fiber Splices
