Future predictions are for total mobk data capacty demand of anywhere between 70 and 50 Imes within 5 years. The greatest demand both today aid in the future s concentrated in the dense urban areas. 3 Subscribe Whle operators have gust about been able to keep up so far (some less so than Tweet others), there is wide recogntbn that somethng radc.a we have to change to delver the capacty requitd. 3 And is not gust about more capacity per se, it's tout the overal speed and (warty of service each customer percewes. Men Customers want to use the hgher speeds possble wth 3.5G and 16 for refiabk use of video and other hgh speed services. These requre robust, fad data conrectiety everywhere we go - whether outside on the street, Ind* our offices, shops or transport hubs. The capacty problem s most noticeably n the dense urban areas rather than sparsely populated rurai areas, and is only gong to get worse. Akhough the total network capacty might grow SOx overal, some peak trafft traffic hotspots are forecast to need 500x or even 1000x n extreme cases. The laws of physics set some constraints The laws of physics provde for three man ways to ',crease total throughput: 1. Add extra spectrum. If avalatile, a staple capacty upgrade at hgh traffic basedations, by addng some extra cards, may be al that's required. Different spectrum bands may als.o need new antenna on the mast and/or new handsetsfsmartphones that can use the different frequencies. New spectrum 6 usuaty very linked, expensive and difIcuk to xquke. 2. Improved spectral effklency. New versions of 3G, such as MSFA, encode the radio signal wth higher orders of modulation to carry more Delft. The new 'IG LTE standard uses a myriad of the latest techniques to carry the maximum possble throughput. However, these hgher rates are only achievable n deal conditions with laded hterference and when very close to the transmtter. Further rnprovements are possible but may requrd additional antenna and coud be qute expensive. 3. Spectrum reuse through smal seas. Most of the vast growth h celutar traffic capacty has in the past been achieved by increasing the number of cells and thls optbn east/ offers the most promise. Thousands of smal metrocek would be instakd n each oty, the maximum number imited by commercial viability rather than techncar barriers.

Network operators are ful of technologists who bye playing with the latest toys. CISCO LTE S also mportant for brand marketing, ensuring a badershp postbn through the promise of high speed, low latency connections. However, is relevant in the short term unless customers buy new smartphones (which are usually subsidised SigalerClesuel by the network operator). In many cases, is not a 'quick win" because of the tine taken for the nstaled base of smartphones to be upgraded. This is why we are seeing some operators bolting to provide Mel LTE coverage through metre macrocels, but instal substantial capacty on the ground using 3G small eels. Alcatel-Lucent p It's also worth noting that the peak achievable weeds of LTE are unikely to be entered (for sustained periods) using macrocels, due to tick of capacty. The short range of a radio Ina to the nearby metrocel (Mach could be 3G or LTE) wit usuaty delver better performance, altering the hghest order modulation to be used for maximum speed and efficiency. le PLETRONICS 1911°'CriOn' ruvuencyCon4,0i Even fan operator could gain access to 3x the current spectrum and deploy LTE throughout (wth a questionable 6x capacty gain), this would st d fat short of the 20 fold or higher growth requited - especiay n the hghest traffic hotspots. 2) WI-n - A quick for? We've seen some great strides being made wth Wi-fr in recent years. Operators have accepted the technology as a complementary and essential component of the overall solution. Mass takeup has enabled k to be very low cost, ea* understood (and becoming even easier to use), and compettile wth al recent smartphones. -At/DIRECT Today, many operators provide their customers with easy access to large numbers of WFFl hotspots, ether deploying ther own or through wholesale arrangements wth Wr-Fi aggregators (or both). TM increases the total capacty of the network SUB10 dramalcaly, and relieves the pressure in high traffic environments AT&T and Verizon report that over hay they noble data traffic now passes through thei pubic Wi-A network Customers, particularly -power users', wit actively seek out Wi-F hotspots in order to find better throughput. Some apps and 0 AMY services are restrtted to work only over WhFr, rather than 3G. But S this what customers realy want? Surely we want sinpicty and to be &rays connected. That mews dentifyirg and searnlessiy connected to a W FFl hotspot h the area when t makes sense, but being able to continue a not in range and/or Symmetrkom when wakng about. The comparatively low RF power of a WhFlhotspot (100mW maximum compared to perhaps 1 to 2W for a metrocel or 20W rakon for a macrocel) is Ideal for indoor envronments but inks range when outdoors. A nye of both Wi-Fi and cellular can be a winning combination, but the evdence from Korea and Japan suggests that relying solely on huge numbers of pubic access WrA hotspots (networks In those countres had 100,000's deployed) won't delver Quortusv the quaky of service to large numbers of users at high throughput on is own. 3) Business as usuak More and higher opacity macrooells The numbers of macrocels in urban areas isn't growing. Ste acquisitbn is diffcut and costly. That's partly because people are becoming more senstive to highly vale masts on the skyline and also because landlords continue to be keen to expbt tlgarL wow. man* 0 . ther monopoly. Qute apart from the irritations due to the laws of physics, the commercial costs don't compere wel vrith metrocel deployments. A recent Alcatel-Lucent study compared the two approaches for a typical Western European urban area found a 38% total cost saving. There is a traffic densty threshold beyond where metrocels become the cheaper sobton. Traffic levels it most developed urban cues have already crossed that pont. 4) Deploy Metrocels A dense underlay of metrocels can delver unbelievable amounts of total capacty, which is exactly what's gong to be needed in the not to distant future. But being closer to the user has other benefts. The short range provides a much better quaky radio channel, which can acheve higher weeds and better throughput. There wi be a lower battery drain on the handset device, increasing battery We. There are many more potential locations to instal metrocels (athough more are Dean. kteretpCS needed). An extra beneft s that each metrocel frees up capacty on the rrecrocet Locations which are difficut to reach IlOrbUide because they are deep nCoors, behind buddngs etc, consume a lot of the tote mecrocel resource to delver a ratites, slow throughput.
