3 Femtocell: Regulatory Framework FCC – Staffers taking notice but no rulemaking or decisions 1 st Mention of “femtocell” by FCC: Feb 2008 “2007 Annual Report of Competitive Market Conditions for Commercial Mobile Services” Discussion of Sprint’s Airave product Prior mention of picocells for trials in airplanes FCC Definition VoIP: Does it apply to Femtocell Use? “Interconnected VoIP services” are services that (1) enable real-time, two-way voice communications; (2) require a broadband connection from the user’s location; (3) require IP-compatible customer premises equipment; and (4) permit users to receive calls from and terminate calls to the public switched telephone network. Femtocell looks like VoIP but CRMS providers are fully regulated

4 Femtocell Interference: Traveling Towers Femtocell interference If the Femtocell is moved into another licensed area, it will cause interference if not “turned off” Femtocells create holes in the macro tower coverage Licensed areas are exclusive to the licensed carrier Nomadic femtocells are the responsibility of the customer’s carrier Customers, not carriers, control the location of the femtocell Rogue or nomadic femtocells cells Femtocell technology provides the opportunity for rogue devices Picocells, for example, are used on cruise ships A ”traveling licensed area” – along with the traveling picocell No regulatory limitations on femtocell devices Location of towers controlled where customers use the service Femtocells without location controls can be used anywhere Interference with rogue femtocells in licensed spectrum

5 Femtocell: Bubbling Regulatory Reaction FCC – Staffers taking notice but no rulemaking or decisions “Unauthorized” Booster FCC is working on CTIA 2007 Booster Complaint: Sudden new action FCC Comments due Feb 22 Rogue Femtocell interfering with cellco “licensed” spectrum FCC enforcement in the home? Warrants required. Not likely… There will be a plethora of femtocell devices – not like a rogue radio station “Interference” 47 Sec 333: “No person shall willfully or maliciously interfere with or cause interference to any radio communications … licensed…” “Interference” No real definition. A condition where a receiver cannot interpret a signal directed at it. FCC Rules Part 15: (1989) low power devices operate without exclusive license. Must take any interference that to device way without complaint Must shut down when interfering with protected license. Low power in a wide variety of frequency ranges. 2.4GHz (“WiFi”) 900MHz 1910 to 1930Mhz sandwiching GSM spectrum

6 Femtocells - 911 Issues More than 140,000 911 calls made each day from wireless phones FCC: Any phone near a carrier tower must have 911 access Applies to femtocells but femtocells are under roofs, move, and not regulated Applies to all phones that can use the spectrum – not just customers If femtocell powered up out of the “approved” location or licensed territory area, should 911 calls be required to be made? Yes. FCC 911 Antenna location regulation Phase I FCC's Order (94-102) require that carriers to deliver location of cell site Phase II mandates that carriers must pinpoint a customer's actual location 2007 FCC 911 NPRM – proposed the idea of a hybrid location requirement FCC 911 Mandate for carriers to provide 911 even with weak signals – This will mean 911 from all femtocells but location is the problem Automatic A/B Roaming-Intelligent Retry (with some modifications), Adequate/Strongest Signal, and Selective Retry.

7 Femtocell Interference: Traveling Towers Femtocell interference If the Femtocell is moved into another licensed area, it will cause interference if not “turned off” Femtocells create holes in the macro tower coverage Licensed areas are exclusive to the licensed carrier Nomadic femtocells are the responsibility of the customer’s carrier Customers, not carriers, control the location of the femtocell Rogue or nomadic femtocells cells Femtocell technology provides the opportunity for rogue devices Picocells, for example, are used on cruise ships A ”traveling licensed area” – along with the traveling picocell No regulatory limitations on femtocell devices Location of towers controlled where customers use the service Femtocells without location controls can be used anywhere Interference with rogue femtocells in licensed spectrum

9 Femtocells: Roaming charge issues There are 90 small facilities-based cellco’s in the US Femtocells can be created without GPS or user restrictions Customers can move their femtocell to other carrier sprectrum U.S. customer could be charged by a foreign carrier where US customer locks on to foreign Femtocell – Mexico example Roaming Issues are created Carrier A customer moves femtocell to Carrier B’s territory Femtocell is used by customers of Carrier B new territory Call through femtocell shows up as delivered by Carrier A Carrier A bills for roaming charges for call originated Carrier B’s territory Difficult to monitor and detect

10 Parasitic Use Problems Carriers will be transmitting calls through unknown internet VoIP carriers like Vonage have regularly been called “parasitic” The voice call is carried on unrelated 3 rd party’s service New opportunities for listening and interfering with calls “Snooping” User will not know they are on a femtocell Imagine suddenly: your cell phone calls are being routed to China hackers Network Neutrality Blocking: Internet providers have blocked VoIP, P2P Sniffing Deep Packet Inspection: Allows ISPs to see/listen to all traffic IPSec tunnel provides limited security

11 The “Big 4” Provider: Business Case #1 Purpose: Femtocell used to solve iPhone data network problem #2 Purpose: Help those with poor in-house coverage #3 The Home Gateway – silence – but this is where the revenue is

12 The New Cellphone Providers Homegateway Femtocell is the Business Case Comcast Clearwire & Sprint TimeWarner Cox WiMax
