  • This year number of smartphones + tablets shipped is higher than number of PCsA whole new market equal to the size of PCs has been born.
  • This slide shows 802.11b/g channel allocations across the well defined regulatory domains. Notice that consecutive channels overlap and this is a well-known issue for wi-fi services. If two or more wi-fi network are within range of each other and operating on overlapping channels, they will be unable to decode each other’s transmissions and thus unable to participate in the collision avoidance protocol. So these networks will hear each other’s transmissions as noise. For this reason, it is recommended that only non-overlapping channels are used for Wi-Fi. In the US these are channels 1, 6 and 11.
  • OFDM has proven to make the best use of the challenging wireless channel. The figure at the lower left shows that the quality of the wireless channel varies as a function of frequency and as a function of time. Even if I stand with my wireless device in one place, the signal at its receiver will fluctuate. The nulls in the signal are due to multipath and doppler fading. The wider the channel, the more difficult it is to equalize the received signal. OFDM takes a divide and conquer approach.OFDM transforms the frequency- and time-variable fading channel into multiple parallel correlated flat-fading channels. The narrow channels of each OFDM subcarrier exhibit small variations, making equalization simple. Thus, the OFDM channel can be arbitrarily wide. When OFDM is combined with multiple antenna techniques that we will discuss later, we can very effectively combat the time and frequency variability of the channel.
  • 3GPP has defined EPS in Release 8 as a framework for an evolution or migration of the3GPP system to a higher-data-rate, lower-latency packet-optimized system that supports multiple radio-access technologies. The focus of this work is on the packet switcheddomain, with the assumption that the system will support all services—including voice—in this domain. (EPS was previously called System ArchitectureEvolution.)Although it will most likely be deployed in conjunction with LTE, EPS could also be deployed for use with HSPA+, where it could provide a stepping-stone to LTE. EPS willbe optimized for all services to be delivered via IP in a manner that is as efficient as possible—through minimization of latency within the system, for example. It will supportservice continuity across heterogeneous networks, which will be important for LTE operators that must simultaneously support GSM/GPRS/EDGE/UMTS/HSPA customers.One important performance aspect of EPS is a flatter architecture. For packet flow, EPS includes two network elements, called Evolved Node B (eNodeB) and the AccessGateway (AGW). The eNodeB (base station) integrates the functions traditionally performed by the radio-network controller, which previously was a separate nodecontrolling multiple Node Bs. Meanwhile, the AGW integrates the functions traditionally performed by the SGSN. The AGW has both control functions, handled through theMobile Management Entity (MME), and user plane (data communications) functions. The user plane functions consist of two elements: a serving gateway that addresses 3GPPmobility and terminates eNodeB connections, and a Packet Data Network (PDN) gateway that addresses service requirements and also terminates access by non-3GPP networks.The MME, serving gateway, and PDN gateways can be collocated in the same physicalnode or distributed, based on vendor implementations and deployment scenarios.The EPS architecture is similar to the HSPA One-Tunnel Architecture, discussed in the“HSPA+” section, which allows for easy integration of HSPA networks to the EPS. EPSalso allows integration of non-3GPP networks such as WiMAX.EPS will use IMS as a component. It will also manage QoS across the whole system,which will be essential for enabling a rich set of multimedia-based services.The MME, serving gateway, and PDN gateways can be collocated in the same physicalnode or distributed, based on vendor implementations and deployment scenarios.The EPS architecture is similar to the HSPA One-Tunnel Architecture, discussed in the“HSPA+” section, which allows for easy integration of HSPA networks to the EPS. EPSalso allows integration of non-3GPP networks such as WiMAX.EPS will use IMS as a component. It will also manage QoS across the whole system,which will be essential for enabling a rich set of multimedia-based services.Elements of the EPS architecture include:- Support for legacy GERAN and UTRAN networks connected via SGSN.- Support for new radio-access networks such as LTE.- The Serving Gateway that terminates the interface toward the 3GPP radio-accessnetworks.- The PDN gateway that controls IP data services, does routing, allocates IPaddresses, enforces policy, and provides access for non-3GPP access networks.- The MME that supports user equipment context and identity as well asauthenticates and authorizes users.- The Policy Control and Charging Rules Function (PCRF) that manages QoSaspects.
  • Most WCDMA and HSDPA deployments are based on FDD, where the operator uses different radio bands for transmit and receive. An alternate approach is TDD, in whichboth transmit and receive functions alternate in time on the same radio channel.Many data applications are asymmetric, with the downlink consuming more bandwidth than the uplink, especially for applications like Web browsing or multimedia downloads. A TDD radio interface can dynamically adjust the downlink-to-uplink ratio accordingly, hence balancing both forward-link and reverse-link capacity.TDD systems require network synchronization and careful coordination between operators or guard bands.
  • This table shows the FDD bands that are allocated in different regions of the world. The regions are shown in right column. FDD spectrum is paired spectrum, so for each channel we have the uplink band and the downlink band. The FDD frequency range spans from around 700 MHz to just under 2700 MHz.
  • The TDD bands are generally higher in frequency than the FDD channels. One reason for this is that TDD bands are more recent allocations. FDD bands have also been allocated for use by 3G. The TDD frequency range is from 1850 to 2620 MHz.
  • This is a partial view of the US spectrum allocation with the unlicensed bands highlighted. Proprietary services are marked in yellow. Standards based services are marked in blue. In the background is the US spectrum allocation chart which you can find at the link shown in the bottom of the slide.The ISM-900 band, aka 915 MHz band is a valuable band because it is relatively wide (26 MHz in the US) and, being lower in frequency than other unlicensed bands, exhibits lower propagation losses, enabling long range transmission. Long used by consumer devices such as cordless phones, garage openers and baby monitors, this band is now assuming a higher importance for new wireless applications involving smart metering and industrial controls.The 2.4 GHz ISM band is heavily used by Wi-Fi and Bluetooth and due to its heavy use services in this band are known to interfere with one another. For this reason 802.11 a/n networks are being deployed more and more in the 5 GHz band where we have 23 channels available in the US. The 5 GHz band is subdivided into several sub-bands subject to slightly different restrictions. More on this later.The 3650 to 3700 band is known as a ‘lightly licensed’ band or ‘contention band’ and only allows devices that implement contention protocol. This band was originally allocated for Wi-Fi but 802.16 (WiMAX) has also adapted its protocol to operate here. Today only WiMAX services operate in this band.Cordless phones are found in virtually all unlicensed bands, all the way up to the 5 GHz band.Ultra wide band (UWB) spans 7.5 GHz from 3.1 to 10.6 GHz. Devices in this band are restricted in signal strength to operate in the noise floor of other services. And hence UWB is relegated to short range links. In the following slides we will cover spectrum regulations and wireless services in more detail.
  • This is a high level summary of the international unlicensed band allocations starting in the 400 MHz range.No license is required to transmit in the ISM and UNII radio bands, but the equipment operating in these bands must meet regional regulatory requirements. The amount of spectrum is limited, and each band eventually fills up, forcing new users to higher bands. If you look up and down this table, you will notice the trend towards wider channels at higher frequencies. Over time, as information content gets richer, wireless services expand to higher frequencies where more spectrum is available. The 800/900 MHz band is favored by manufacturers of low cost proprietary products because this band is available world-wide opening large markets for consumer products. Recently this band has started to attract attention of vendors addressing the emerging smart metering and industrial control applications.The 2.4 and 5 GHz ISM and UNII bands enjoy broad international allocation and are heavily used by 802.11 services as well as Bluetooth.The 24 GHz ISM band is available in the US and internationally and is commonly used for speed radarsAnd the ISM spectrum in the 60 GHz region is targeted for use by the emerging short range high definition video and other applications requiring high throughput

    7. 7. 7Spectrum Sensing Technical Challenges• Very low threshold of -114 dBm Below noise floor of most receivers Requires sophisticated averaging or other innovative techniques Averaging could be time-consuming• False detects During initial FCC testing of early spectrum sensing prototypes, the key issue was false detects – due to unreasonably low threshold Adjacent TV channel leakage can be about 30 dB above the sensing threshold• Service boundaries are not well-defined. For example, if the sensing radio is a few feet outside the boundary of the TV station region, the sensing circuitry might still detect the TV signal. Is this a failure?
