On the World Mobile Communications Conference in San Francisco, San Francisco, MWC Americas, you can see that each telecom operator is active in the edition network market ...
The Honeycomb (IoT) market is in the departure period, and the US Telecom AT & T, which has begun to operate the LTE-M network, supports diverse IOT business model, and because the company can estimate the amount of data, the customer will make years of data programs Incorporate product costs; for example, the car is allowed to use the SIM card to charge the cost of emergency rescue calls to the driver to charge the driver.
AT & T is the same as other service providers, regarding asset tracking as a large but diversified market, whose users include OTIS elevators, McPherson Oil's oil storage slots, and GE's smart street lights.
3GPP defines the LTE-M and NB-IOT as part of the Release 13 specification, and the industry expects that the organization provides two generations of annual upgrades before the 5G IoT specification panels that have not been defined. - Brelease 14 and 15 The mesh networking, better location tracking, and possibly the transmission distance may be extended.
Karri Kuoppamaki, Vice President, US Telecom T-Mobile Technology Development and Strategy, said: "NB-IOT has been optimized for LTE; other options will appear between LTE-M and Category-1 LTE, but the next focus Will be in 5G IOT, which is expected to promote smaller, more power-saving equipment, and coverage may be better. "Module supplier Telit demonstrates the diversity of cellular IoT and various LPWA technology in MWC MWC. : EE TIMES)
LPWA technology supplies commercial anti-honeycomb IoT competition
Telecom operators are actively grabbing the honeycomb IoT market. I hope that I have entered the market for more than two years, and the low-power WAN (LPWA) competition technology of SIGFOX and Lora leader; and the LPWA field is still in the next few years. Sugfox and LORA are maintained in the status of the population and the LORA uses the 800 ~ 900MHz-free communication band to break out of the early entry of the world.
According to market research institutions IHS Markit, SIGFOX expects to be the highest in IOT market share, and thereafter sequentially NB-IOT and LORA; LTE-M will fall behind. The fourth distance is ranked. SIGFOX service locks the IoT market pyramid broad bottom, support short, unverified minimum data rate message transmission, its module cost is $ 2, data transfer rate is in the United States, which is 10 per year, as long as half of Europe.
Allen Proithis, president of SIGFOX North America, said: "If your data is very large, the transfer rate may be high to 10-20 dollars a year, but very few users will reach that level ... if you need 3GPP specifications Things, it is impossible to be so cheap, power saving or simple, especially for devices that only transmit minute data. "
As with its competitors, Sigfox is reluctant to disclose the current number of users, only to use the Oilfield, large farm, and the San Francisco city water supply system; 32 countries in the world have built the network, potential Market (Addressable Market) covers 600 million people.
SIGFOX will treat himself as a network technology provider, usually in the development and deployment of third-party partners cooperation with software required to establish some IoT service; "The light is in the United States, we have six different asset tracking Equipment, because each customer is different for the demand for sensor combination. "
So far, SIGFOX and cellular communications operators do not exchange too much in the local local area of Japan, and the cooperation with T-Mobile only for one or two markets, SIGFOX and cellular communications operators do not exchange; but Proithis revealed: "Maybe there will be Some progress, because operators want to provide one-stop service. "New Corporate TrackNet CEO Hardy Schmidbauer said that the license band LPWA technology can provide an option than the honeycomb IoT cost (Source: EE Times)
Lora Alliance, which is followed after Sigfox, has made business with more than 40 network operators, including France Orange and Europe's COMCAST; the alliance does not sell services, but provide open specifications to make anyone adopted, establish Public or private networks have attracted more than 500 alliance members and at least 350 test operations networks.
Hardy Schmidbauer, a new company TRACKNET CEO, using LORA and Wi-Fi technology, said that LORA's asynchronous, Spread-Spectrum network, can strengthen transmission distance and minimize interference; The company is one of the representatives of the early adopters of LORA technology, using the SEMTECH chip to support its first service.
Schmidbauer said that the synchronous cellular IoT network consumes too much power for more than 5 years or more, and LORA equipment uses a battery that is second to 2,000 mAh, 3.6V specification; he further pointed out that all LPWAs for licensed frequency bands Technique: "It is not to compete with NB-IOT, like Bluetooth and RFID, both of which are different and the area is quite small."
