10. Mobile TV: Video is very popular on smartphones, but it is mainly YouTube and shorter segments from other channels. You can also watch movies and sports games, depending on the operator. However, mobile TV is still not widely used. There are still some obstacles to watching TV on a 4-inch screen. Qualcomm's FLO TV over-the-air (OTA) service, offered by AT&T and Verizon, was recently closed due to a lack of customers and viewing equipment. But with the finalization of the new ATSC A/153 mobile TV standard and the launch of related chips, we may soon see local TV stations supporting the new standard launch more OTA TVs. Siano's new SMS1530 TV receiver chip handles the new ATSC mobile/handheld (M/H) standard. If the antenna problem can be solved well, it is expected that free TV will appear on some smart phones in the future.
9. NFC: Near-range wireless communication (NFC) short-range, 13.56-MHz wireless methods have been around for several years, and some chips can turn the phone into the next smart card. Jeff Miles, head of mobile trading at NXP Semiconductors, said that 2011 is expected to be a year for NFC. NXP Semiconductors produces NFC chips for mobile phones. The company predicts that the world will deploy more than 50 million NFCs in smart phones this year. Nokia, RIM and Google all support NFC. Google said it will include NFC functionality in its next version of the Android operating system. It is expected that NFC will become an essential feature of smartphones, allowing smart phones to be used for shopping, access control, transportation and booking.
8, wireless modem: USB dongle is a notebook and netbook users wireless Internet access the main way. Now with the advent of HSPA+ and 4G services, more users purchase these devices. ABI Research estimates that 93 million of these modems were sold in 2010. Sales will continue to grow, but the main trend is that more notebook manufacturers will embed 3G/4G modems and Wi-Fi radios directly into PCs and laptops.
7. GPS/Navigation: According to ABI Research, the number of global navigation devices is expected to increase from 100 million in 2010 to 283 million in 2015. Also preferred are personal navigation devices (PNDs) from vendors such as Garmin, TomTom and Magellan. However, smart phone GPS and in-dash navigation systems have grown rapidly.
6. M2M: The machine-to-machine (M2M) mobile connection for monitoring and controlling various types of mobile devices continues to grow steadily. ABI Research report said that in 2015 these connections are expected to exceed 297 million. In 2015, shipments of M2M modules are expected to quadruple in 2009, exceeding 114 million. The GSM/GPRS data connection is dominant because of the low speed required for M2M telemetry applications. However, EDGE has not been adopted much because many users are turning to 3G WCDMA to prevent their products from falling behind due to the development of wireless networks.
Antenna issues: The new smartphones have multiple radio frequencies: two or more wireless transceivers at different frequencies, Wi-Fi, Bluetooth, GPS, and FM radio and/or television. This means that more than one antenna is needed. The new handset will have multiple bands and multiple modes for backward compatibility with older 3G and early systems. In addition, there are multiple input/multiple output (MIMO) problems or opportunities that require multiple antennas. Obviously, more efforts need to be made on the antenna, and vendors are solving this problem. "Consumers are eager for elegant multi-functional 4G smartphones and tablets for mobile broadband access. However, internal MIMO antennas must work in as many as 10 different frequency bands, providing four times the throughput and more than the previous machine. The antenna takes up less space," said Charles A, vice president of marketing and business development at SkyCross. Riggle said, "Technical progress in the field of antenna design is critical for the new 4G devices being rapidly accepted and successfully deployed by the market."
4, Tablet PC: Apple's iPad has been a success, Samsung and Dell and other manufacturers are selling tablet computers, more like a mobile device, not a PC. Of course, these devices are wireless products. They have a large screen and storage capacity and are very popular with gamers and video lovers. In the mobile environment, the bandwidth and speed requirements of games and videos are the highest, so it will definitely have a big impact on 4G.
3. Femtocell: These short-haul home/office base stations rely on broadband cable or DSL connections to communicate with operators and are expected to play an important role in the rollout of LTE 4G. Femtocell and its close relatives, pico and micro base stations, cost less than macro base stations, and can provide users with faster and more reliable connections in a variety of environments. It is expected that they will allow the 4G infrastructure to expand faster than usual and allow operators time to complete the backhaul upgrade. According to the Femto Forum, 17 operators are already providing femtocells, and five are preparing to follow up in the near future. Dell'Oro estimates that by 2012, the global femtocell deployment will generate $4 billion in operating revenue.
2. Spectrum crisis: If you can't ease the spectrum shortage, don't expect LTE to roll out. With some new 700-MHz spectrum available, LTE will get a good start. However, in the next few years, if there is insufficient spectrum, the further development of new technologies and their acceptance by the market will be seriously affected. The Federal Communications Commission (FCC) has promised to provide up to 500 MHz of new mobile spectrum in the next 10 years. Recently, the National Telecommunications and Information Administration (NTIA) suggested that 115 MHz of new spectrum be redistributed to wireless broadband services in the next five years. Currently these spectrums are occupied by other services but can be released. Some of the future available spectrum includes 1675 to 1710 MHz, 1755 to 1780 MHz, 3500 to 3650 MHz, 4200 to 4220 MHz, and 4380 to 4400 MHz. This is very good news, but providing new spectrum should be the top priority for the FCC and NTIA.
1. Network Neutral Threat: The FCC plans to supervise the Internet, in order to protect anyoneâ€™s right to access any content without restriction at any time. However, supervision will cause serious adverse effects on the entire Internet access system, especially the fragile wireless infrastructure. FCC regulation seems to be unavoidable, but it is hoped that wireless will receive special treatment to ensure that it continues to be a viable option.
