CME Group offers connections to a wireless network on the trading floor to facilitate the use ofwireless local area networks (LAN) by all market participants. The wireless network is designed toalleviate the need for each interested member firm to design, purchase, install, and maintain its own
wireless network antennas on the trading floor as well as to significantly increase the number ofwireless devices that can be used by the trading floor community. CME Rule 507 (“ElectronicDevices”) governs the use of electronic devices on the trading floor. The text of CME Rule 507
appears on Page 2 of this Advisory Notice.
This Advisory Notice is being issued as a reminder to the trading floor community of CME Group’s
general policy on the use of wireless devices/software on the trading floor. The policy is as follows:
1. Only wireless LANs that have been approved by the Exchange are allowed on the trading floor.
2. The use of any device or software that monitors, sniffs, probes, accesses or otherwise ‘sees’
wireless networks is strictly prohibited.
3. No cordless phones (i.e. those with a base station and handset) or wireless gaming systems ofany kind are permitted on the trading floor. Cellular phones, including all smart phones, arepermissible provided that bluetooth, mifi and wifi technology have been disabled.
4. The use of an 802.11 bridge (mifi, wifi, hotspot or similar technologies), bluetooth, or
wireless printers on the trading floor is strictly prohibited. All members, member firms
and their staffs must ensure that all unauthorized wireless signals are disabled on any
device that is being used on the trading floors.
5. The majority of smart phones, laptops, tablet personal computers, and printers now being soldhave wireless network adapters (802.11b/g/n and/or 802.11a) built in at the factory. These
adapters must be in an “OFF” state in order for these devices to be brought onto the trading
floor and must remain in an off state until removed from the floor. If you need assistance indetermining the state of the adapter, please call the Floor Technology Support Help Desk at
312.347.5611.
The use of unauthorized wireless communication equipment on the trading floor is strictly prohibited.
Violation of these policies may result in disciplinary action and unauthorized wireless equipment will
be immediately disconnected and removed from the trading floor.
