如何使用iBeacon实现iOS应用中的商场导航(三)

如何使用iBeacon实现iOS应用中的商场导航引言随着移动设备和智能手机的普及,人们更加依赖手机来进行购物和导航。

在商场中,人们常常迷失在复杂的商场布局中。

为了解决这个问题,商场导航成为一个热门的需求。

而使用iBeacon技术实现商场导航成为了一种高效而且可行的解决方案。

一、iBeacon技术简介iBeacon是一种低功耗蓝牙技术,它基于蓝牙协议,能够实现设备之间的短距离通信和定位。

iBeacon设备通常被放置在商场的不同位置,它能向周围的设备发送广播信号,告知设备自己的唯一标识符以及信号强度。

二、商场地图构建和数据采集要实现商场导航,首先需要构建商场的地图并采集相关数据。

在商场中安置iBeacon设备,并记录每个iBeacon设备的位置和唯一标识符。

为了准确获取iBeacon设备的位置,可以配合使用GPS或其他定位技术。

此外,在商场中还需要布置WiFi设备,以便获取用户设备的位置。

通过不断收集并整理这些数据,可以得到商场的准确地图和每个区域的位置信息。

三、iOS应用开发在iOS应用中实现商场导航,主要依赖于Core Location框架和Core Bluetooth框架。

首先,需要在应用中获取用户设备的位置信息。

通过Core Location框架,可以获取到用户设备的经纬度坐标,然后与商场地图上的位置信息进行匹配,得到用户在商场中的位置。

接下来,需要监听iBeacon设备的信号,并获取到每个iBeacon设备的唯一标识符和信号强度。

通过Core Bluetooth框架,可以扫描周围的iBeacon设备,并获取到相关信息。

然后,将获取到的iBeacon 设备信息与商场地图上的位置信息进行匹配,得到用户设备附近的iBeacon设备和对应位置。

最后,根据用户设备的位置和附近的iBeacon设备位置,利用算法计算出用户所在的区域,并在应用中显示商场地图。

通过将用户设备位置和iBeacon设备位置实时进行匹配,实现商场导航功能。

Icom IC-7000 Frequently Asked Questions (FAQ)This guide was created to answer the most commonly asked questions about the Icom IC-7000. The goal is two-fold:1) Condense the discussions found in the Yahoo group to the raw information providing a definitivesource for the FAQ reader2) Remove these recurring questions from the group to improve the “signal to noise ratio” Instructions for updating, correcting and adding information are located at the end of this FAQ.IC-7000 Unique Features• The IC-7000 was the smallest multimode radio available at its introduction (and the time of this writing)• It was the first truly mobile radio to feature IF-DSP (customizable filters – nothing to buy)• Filter width adjustable by mode with “sharp” and “soft” shape factors• Dual ADI Blackfin DSP Processors - feature set similar to the IC-7800, IC-756 Pro III• ACG loop performance controlled by DSP• Auto notch plus dual manual notch filters for up to 70 dB of attenuation• Noise blanker features adjustable pulse width and depth of cut• Internal RTTY decode and dual peak RTTY filter• High stability crystal oscillator is standard• Voice synthesizer standard• VFO knob includes a working “spinner”• The VFO knob tension is adjustable from free to tight and detented – great for mobile operation!• Microphone and external speaker jacks on both the head and body• Color composite video output available at all times to support a larger monitor• Multifunction display shows complete receiver status, S-meter/power output, ALC, compression, SWR and final temperature on a single screen• Semi-real-time spectral display 25-500kHz wide with peak hold and SWR sweep meter• VHF NTSC TV reception with internal modification• Many functions, including band stack registers, direct frequency entry, mode, filters and speech synthesizer available directly via the microphone (no menu navigation required) • Two programmable function keys on microphone for most used functions• CW/Voice memory keyer with 4 memories each and internal recorder feature• CW/voice keyer directly accessible with simple box described in manual• Thermostatically controlled fan• Less receive standby current draw than the IC-706MKIIG• Remotely mountable head• 6-pin data jack and 13-pin accessory jack• Customizable opening messageUser Measured SpecificationsPower outputThe IC-7000 maximum output power drops as voltage drops. This behavior is consistent with other radios as shown by the Yaesu FT-450 results below.The band tested below was not specified.13.84 2.0 17 9313.49 2.0 17 9213.01 2.0 17.5 9212.50 2.0 17.5 9012.02 2.0 16.0 8011.50 2.0 14.5 7011.01 2.0 14.0 6010.50 2.0 12.5 5010.00 2.0 11.5 409.50 2.0 XMIT FAILEDVoltage measured at power supply. Cables supplied by Icom. Power out as indicated in CW mode on attached tuner into a dummy load. At full voltage I had a full 100w PEP on SSB.<Marc W0KYZ>By comparison, these are the measurements that I obtained from a new Yaesu FT-450AT late last year: 13.8V - 100W12.5V - 100W12.0V - 75W11.5V - 68W<VR2AX> I looked up the % charge chart for my Trojan Deep Cycle battery:100% 12.70V80% 12.46V75% 12.40V50% 12.20V45% 12.16V25% 12.00V10% 11.94V5% 11.92V Discharged @ 11.90V<Jack_son>Receive standby currentIcom specs say 1.3A on receive squelched and 1.6A full volume.I checked mine. I got 1.36A two minutes after power up with default settings on 2m FM. Full volume (painful) was1.52A. I found I could save about 40mA by reducing "LCD Bright" to minimum (and still read the display) and another 40mA by turning off the switch backlighting. The readings were a little tough to validate because the fan is variable speed and can affect the readings by more than 100mA.These numbers seem consistent with the published Icom specs. It's not exactly milliamps but it's still 500mA less than the IC-706MKIIG specs. <Scott N7SS>How do I…?How do I hook a monitor to my IC-7000?The IC-7000 uses a 1/8” mono mini jack to provide composite video out. Any monitor, TV or VCR that supports composite video input (yellow RCA jack) can be used as a display. Although the 1/8” mini jack is small, it’s not a standard video connector. Radio Shack offers a 6 foot cable (Catalog #: 42-2444) for only a few dollars that has a 1/8” mini plug to RCA plug and will connect the IC-7000 directly to a standard composite monitor/TV.It is also possible to use an adapter to convert the 1/8” mini jack to an RCA to allow the use of a standard RCA cable. Rigid adapters should be used with caution because the jack can be pulled off the main board if too much torque is applied.“To use with a standard computer monitor, it is necessary to convert the composite video to RGB video with a device like the KWorld TV Box 1680ex.I use this one and it works ok but the above is better: /mpd/tvbox9.html<Steve Ellington, N4LQ>How do I use a Bluetooth headset with my IC-7000?“Works great. See link below from K7SFN. /projects/bluetooth.html”<Dave, KI4KQ>How do I connect more than one CI-V device to my IC-7000?The Icom CI-V interface is a serial bus design. This allows more than one device to be connected to the radio CI-V interface (amplifier, antenna switch, SteppIR antenna, additional radios, etc.). “To connect these devices get a flexible adapter like the Radio Shack 42-2437 or even a three-way adapter like the Radio Shack 42-2458”. <Doug Faunt, N6TQS>How do I get better transmitted audio?The IC-7000 was designed as a mobile radio and the microphone was intended to be used in high noise environments. Although the Heil microphones and W2IMY equalizers provide excellent audio, many people want to maintain the functionality of the stock microphone and get better audio without the expense of these options. AB5N has created a modification for the stock microphone at/ that creates a “hotter” microphone and higher quality audio. There is also a microphone modification posted at http://www.mods.dk/.The IC-7000 has two microphone jacks but the Icom manual specifically states that only one microphone should be used at a time. This is likely because both microphones would be hot at the same time. Some have suggested a mute switch (disabling the mike element) in the stock microphone. This would allow the stock microphone to be used as a “remote control” in one mike jack with a headset in the second mike jack.How do I use my IC-7000 on 60m?Page 40 of the IC-7000 manual provides information on 60m operation and is quoted below.To assist you in operating the 5 MHz band correctly within the rules specified by the FCC, transmission is impossible on any 5 MHz band frequency other than the 5 frequencies indicated in the table below.IC-7000 Display Frequency* FCC Channel Center Frequency*5.33050 MHz 5.33200 MHz5.34650 MHz 5.34800 MHz5.36650 MHz 5.36800 MHz5.37150 MHz 5.37300 MHz5.40350 MHz 5.40500 MHzNOTE: We recommend that you store these frequencies, mode and filter settings into the memory channel for easy recall.*The channel center frequencies that are specified by the FCC, show the center frequency of their passband. However, the IC-7000 displays carrier point frequency, so set 1.5 kHz below from FCC channel center frequency.How do I get full power output when transmitting?The IC-7000 was designed to deliver full power output at 13.8 volts. This is the voltage provided by most power supplies and the alternator output of a vehicle. The voltage table at the beginning of this FAQ shows output as voltage drops. When using the radio from a battery it is necessary to use the largest possible power cabling and a battery voltage booster to maintain the 13.8 volts required for maximum output.I use my IC7000 on CW almost exclusively, and I operate ONLY mobile. I use the N8XJK booster / with no problems at all. For a while I used it with the RF sensing, but no longer do so... not because of any performance problems, but because when the engine is running I don't need the booster, and when in receive I don't hear any noise problems from the booster, so I decided to so away with the additional wiring needed to use the RF Sensing. <Dave- K9FN>“I will ad that the MFJ-4416 voltage booster has helped greatly when the vehicle isn't running. This radio and many other mobiles do not Tx full output power on less than 13+ volts. So either get a battery voltage booster or keep the vehicle running.” <AE5MH>How do I use my radio in VOX mode?“Two things two check. You are in a voice mode and you have turned VOX on. I just tried it and it works with the stock 151 microphone. Be sure the word VOX shows up on your display.” <Steve EllingtonN4LQ>“Turn the VOX Gain up reasonably high, and turn the Anti-VOX as low as you can with out the speaker triggering the VOX. My 7000 works great with stock microphone in VOX mode.” <Dave - KI4KQ>How do I access the CW/Voice memory keyer?The CW and voice keyer options are accessible through the menu. When using the keyers via menu, it is not possible to access other features or the popular multimeter screen. There is a simple resistor network with switches shown in the manual to allow immediate access to the CW/voice memory keyer.“I made the device in the photo for solve this problem using the circuit at the 135 Page. I use my 7k for contesting and expeditions so the voice message function is a powerful help but use it via the menus is complex. /ea1nt/7kbox.htm <Luis EA1NT>How do I use a Turbo Tuner and screwdriver antenna with an IC-7000On the Turbo Tuner Web site, N2VZ is shipping Turbo Tuners setup for the 7000 AND the software update for Turbo Tuners that were programmed for 706, to make it a 7000 tuner. He will email you the update to flash your 706 Turbo Tuner thru the RS232 port on the Turbo Tuner./<Kent KQ4KK>How do I enter DTMF tones for Echolink/IRLP or repeater control?The stock IC-7000 microphone has many functions but like the IC-706 family, it can’t generate DTMF tones. There are two solutions offered by Icom. The first option is the same DTMF microphone used by the IC-706, the HM-154T.There are also 4 DTMF memories of up to 24 digits described on page 67-68 of the IC-7000 manual. This allows recording command/control sequences in these memories. Set Menu Option 38 specifies which DTMF option appears when F-2 is pressed in the menu.Can I use my IC-706 accessories with my IC-7000?Most accessories from Icom and third parties will work directly with the IC-7000. There are a few exceptions. The Icom remote kit is different for the IC-7000. The body and head bracket are the same but the remote cable has 10 pins, rather than only 8 pins. The microphones are largely compatible but the IC-7000 does not have an audio output line in the microphone cable. This could effect some TNC cables and older Heil headsets. The later Heil headsets have a separate speaker plug. There have also been some compatibility issues with third-party tuners (LDG and Turbo Tuner) although ROM upgrades are generally available to address these issues.Where do I find…?DC Power connector“New HF radios from Japan, introduced in the past 5 years operating on 12V DC, like the ICOM IC-7000, Kenwood TS-480, Yaesu FT-450, Yaesu FT-2000, and the new ICOM entry level radio all use the same connector, wired the same way.” <John Bee N1GNV – Quicksilver Radio>Quicksilver Radio - /DCpower.htmTower Electronics - /Powerwerx - /Wimo - http://wimo.de/cgi-bin/verteiler.pl?url=netzgeraete-zubehoer_d.htmlMonitorThere are too many monitor options available from too many sources to list here. The IC-7000 provides composite video out. This can be run into most TV sets and VCRs with the appropriate cable (1/8” monaural mini plug to RCA plug).Small monitors can often be found on eBay and any place that sells car audio/video. In-dash DVD players and many navigation systems include a composite video input. There has even been some discussion that a Toyota Prius instrument panel has an input that could be used for an IC-7000.Icom uses a 7” Xenarc 700YV monitor in the display they use at hamfairs. This monitor is more than what is necessary for most users. The rated LCD brightness of 500 cd/m² and contrast ratio of 400:1 crates a nice image. These are the two most important numbers when determining the quality of an LCD display. Often these numbers are not available and the price is the only indication of the relative monitor quality.CI-V computer interfaces for serial and USBIcom sells the CT-17 interface, which offers 4 CI-V ports and a single DB-9 serial port. There are a number of less expensive options available on the market in both serial and USB. These are commonly found on eBay. Radio Shack also has some scanner programming cables that will work.“I purchased the Radio Shack 20-047 USB Programming Cable & Driver Software today.(the number and description is right off their label)I followed their directions and connected the USB plug after installing the driver. It connects at 19,200 bps and has not given one sign of improper connection...This is faster and easier than the CT-17.I used a 20 foot stereo extension to get to the ICOM and used the stereo to mono adapter supplied with the interface to plug in at the radio end of the connection.18 hours later, I am sure this is the best way to go.” <im2old2run>Interfaces are also available from:West Mountain Radio - /RIGtalk.htmMFJ /Product.php?productid=MFJ-5383IControl softwareThe IC-7000 is similar to the other Icom HF radios and can use much of the same software written for the IC-706 family (although the radio address may need to be changed). More software is offering native IC-7000 support. One of the first and best is Ham Radio Deluxe (HRD) and is available for download at no cost from /.Memory programming softwareThere are a number of packages specifically designed to program the memory channels in the IC-7000. Rumtrol7k http://www.dl2rum.de/rumsoft/RUMtrol7K.htmlIC7000BKT /ic7000bkt_en.htmCI-V Cat.program/Memory Manager http://www.tellina.nl/software/Radio IssuesThe IC-7000 runs hot even on receiveThere are reports of the IC-7000 running hot despite most of the radio body being cooler than the IC-706. There are three points in particular that can run warm; the display because of the backlight, the area behind the speaker where the DSP ICs are heat sinked and the actual heat sink on the back of the radio. Here is a chart showing relative temperatures of various devices with color displays. The temperatures below were taken with an infrared thermometer after a 24 hour warm-up period at 71 degrees F with no transmit.Icom IC-7000 91°F 33°CIcom IC-2800 107°F 41°CSharp 15” TV/Monitor 85°F 29°CG2G 5” TFT Portable Monitor 106°F 41°CInitial 7” Portable DVD Player 85°F 29°CThe display runs about 91°F. The heatsink on the rear runs 99-103°F (in receive). The cooler areas on the back are 92-96°F. The temperature on the top ranges from 95-109°F. The area directly behind the speaker is the hottest at 109°F. This is directly over the silver box containing the DSP chips.The thermometer on the multimeter display shows the rear heatsink temperature. The final output transistors use this heatsink.Many users have installed fans over or behind the radio to increase the airflow over the chassis. Care must be taken with fans in dusty environments. There is also a fan modification published onhttp://www.mods.dk.Strange behavior on transmit (shutting down, resetting, changing frequency, etc.) This is most commonly a grounding/RFI issue. Make sure the radio and antenna are properly grounded. If the separation cable is being used, attempt to route it away from RF sources and be sure to use the screw to attach it to the radio.Audio feedback during transmitCheck to make sure you don't have the "monitor" turned on. Usually, you just use the monitor when transmitting digital modes.• Push SET button (AF gain control knob) upper left hand corner of radio.• Go to "Set Mode" > OTH > Monitor. Set to OFF<Brian, KC4UKR>High frequency (8kHz) tone in audioVery early models of the radio had a noticeable tone at 8kHz. This was not audible through the internal speaker because the internal speaker is “communications grade”, meaning it has a frequency response limited to voice frequencies. It was also not audible when using Heil, David Clark and othercommunications headphones or speakers. It was most obvious when using inexpensive “Walkman” style hifi headphones which are excellent at reproducing non-voice frequencies.Icom addressed this within a few months after production began with some capacitor and grounding changes. This modification should be available at no charge for units in warranty.Low level hiss in audioMany radios have a small amount of hiss (white noise) when the volume is set to the minimum value. This hiss remains at a constant level as the volume is increased and is quickly overwhelmed by signal audio. The hiss is apparently internally generated. There is no known solution but some users insert attenuators in the audio line. Since the hiss is a fixed level, it will reduce the hiss level while allowing the signal level to be increased with additional AF gain.This audio hiss is very low through the internal speaker because it is “communications grade”, meaning it has a frequency response limited to voice frequencies. Any external speaker or headphones should also be designed for communications work, rather than hi-fi, so as to minimize this issue.S-meter reads lowThe IC-7000 S-meter is very accurate but as a mobile unit is calibrated to read accurately with the preamp enabled.Changing the transmit audio bandwidth results in poor transmit audioThe Icom IC-7000 supports changing the transmit audio bandwidth. There are three predefined settings which can be modified. Because it appears the transmit equalization feature was cut, there is no way to rebalance the audio as the bandwidth is narrowed. This makes the audio quality very poor at narrow bandwidths. If DX-quality narrow audio is desired, the best solution is a good DX microphone or an external equalizer like those from W2IHY.。

iBeacon技术的无限可能

iBeacon技术的无限可能

四大情景告诉你苹果iBeacon技术的无限可能腾讯科技[微博]汤姆2013年12月13日10:14[导读]人们对于iBeacon技术最大的期许还在于零售业,越来越多零售商家开始讨论有关店内导航和实时定价的话题腾讯科技汤姆12月13日编译你是否曾经想象过自己可能置身于这样一个世界中:当你走进沃尔玛超市的时候,你手机中的购物清单会自动转化成一张个性化地图,并为你推荐最值得买的商品;当你站在一场音乐会门口的售票机前时,你拿出手机便可以一键完成门票的购买;当地走过当地的一个酒吧时,你可以在无需使用现金的情况下便完成付费、甚至给予小费。

以上的这一切并非幻想,而是iBeacon的世界!所谓iBeacon技术指的是通过使用低功耗蓝牙技术(Bluetooth LowEnergy,也就是Bluetooth 4.0或者Bluetooth Smart),iBeacon基站便可以自动创建一个信号区域,当设备进入该区域时,相应的应用程序便会提示用户是否需要接入这个信号网络。

通过能够放置在任何物体中的小型无线传感器和低功耗蓝牙技术,用户便能使用智能设备来传输数据。

需要指出的是,苹果自从iPhone 4S和第三代iPad就开始在移动设备内置低功耗蓝牙技术,因此几乎每一部较新的iPhone和iPad都可以成为iBeacon 接收器或发射器。

对此,美国知名科技媒体《连线》就这一技术未来的无限可能为我们列举出了四个实用情景案例,具体内容如下:1. 现实世界数字化当苹果在今年夏天的“全球开发者大会”(WWDC)上首次提及“iBeacon”这一单词的时候,他们例举了上文中利用iBeacon快速购买演出门票的例子。

但事实上,有关这一技术的实用领域还远远不限于此,因为这一技术的出现使得在室内环境下对用户进行精确定位变成了可能。

通过周边多个iBeacon收发器,用户的位置可以被精确定位至几英尺的范围内,这一定位技术被业内统称为“微定位”(microlocation)。

一、基础概念
1.1“摇一摇·周边”是什么?
“摇一摇·周边”是微信针对低功耗蓝牙硬件(支持iBeacon协议,下文简称“iBeacon设备”)提供的连接入口。

(69769 66@扣扣.c om注明百度文库咨询iBeacon)
在手机蓝牙打开状态下,当用户在微信中打开“摇一摇”时,如果周围有iBeacon设备,则”摇一摇”中会自动出现“周边“入口。

此时用户摇一摇手机就会获得周围的信息。

1.2什么是iBeacon协议?
iBeacon协议是苹果公司推出的基于低功耗蓝牙硬件的广播协议。

此协议是公开和开放的。

iOS7.0和Android4.3.3以上的操作系统版本均支持此协议。

其工作方式是,配备有低功耗蓝牙通信功能的设备向周围发送自己特有的iBeacon ID,接收到该ID的应用软件会根据该ID触发行动。

1.3什么是iBeacon设备?
iBeacon设备是指支持iBeacon协议的硬件。

(注:下文中“设备”,均指iBeacon设备)
1.4什么是iBeacon ID(下文简称“设备ID”)?
iBeacon ID是指iBeacon设备向外广播的ID。

该ID由UUID、Major 和Minor三个字段组成。

为了确保设备ID的唯一性,所有接入”摇一摇·周边”的设备ID,需要在”摇一摇·周边“后台申请获得。

1.5”摇一摇·周边“产品的基本原理是什么?
A.商户进入portal,申请”摇一摇·周边“的使用权限。


请通过后,系统会根据申请的设备ID数量,随机生成设备ID列表;
B.商户在portal将自己提供的服务(URL模式)与已分配的设备ID关联;
C.商户将设备ID写入iBeacon设备。

开启设备后,该设备会广播已写入的设备ID;
D.用户在手机蓝牙打开的状态下,在该iBeacon设备的信号范围内打开微信,进入”摇一摇·周边“入口,摇一摇手机,就可以获得商户展示的消息,点击消息跳转到商户在申请服务时填的URL,体验商户提供的服务。

二、用户侧的体验流程
2.1用户如何使用”摇一摇·周边“?
用户打开蓝牙->打开微信,进入“摇一摇”->“周边”页卡自动出现,与“人”和“歌曲”并列->用户摇一摇,出现消息,点击消息进入相应的页面。

2.2用户已经打开蓝牙,为什么没有看到”摇一摇·周边“入口?
A.可能是微信版本不支持。

请确认iOS微信版本是中国大陆5.4及以上版本,(6976966@扣扣.c om注明百度文库咨询iBeacon)andorid微信版本是6.0及以上版本。

微信繁体中文
6.1版本也会支持”摇一摇·周边“;
B.可能是地域设置有问题。

请确认用户的地区设置在中国(设置-通用-多语言环境-区域格式),海外版暂时没有;
C.可能是系统版本不支持。

请确认iOS手机系统在7.0以上(7.1.2以上会比较稳定,7.1.1偶尔会有bug,需要在设置-隐
私-定位功能中开关几次微信定位功能或重启手机);Android手机系统在4.3.3以上;
D.可能是蓝牙被占用。

如果正在使用蓝牙耳机、智能手表或其他可穿戴设备,请先关闭。

2.3用户在”周边“tab里,为什么摇到“未能识别周围有效信息”?
A.可能是设备ID配置问题。

该设备UUID配置有效,但Major 或Minor配置有误;
B.可能在“页面信息“设置了时间或地域限制。

在设定时间或地域之外,用户收不到有效信息。

三、商户申请流程
3.1申请条件是什么?
A.需开通微信公众帐号,且公众帐号处于认证成功状态。

订阅号及服务号均可;
B.已经开通门店管理,并且至少有一家门店通过门店审核;
3.2需要提交什么资料?
请在PC侧登录“摇一摇·周边”的申请入口,查阅相关资质文件。

3.3如何申请?
A.PC侧登录“摇一摇·周边”的申请入口:ht*t*p://z*b.we*i*x In.q*;(去掉*)
B.登录后,填写基本资料,提交申请;
C.审核周期为3个工作日;
D.页面配置及ID申请,请在审核通过后,登录“摇一摇·周边”Portal获取相关信息,进行配置及申请。

四、iBeacon设备相关问题
4.1如何购买iBeacon设备?
A.由于iBeacon协议是开放协议,商户可以自行通过任意渠道购买支持iBeacon设备(譬如搜索“iBeacon设备“或者在电商网站购买),微信无任何限制。

B.如果对iBeacon设备完全不了解,可以参考以下iBeacon设备厂商。

注:列表排名不分先后,仅供商户参考。

微信不做任何推荐,且不对购买过程和使用过程中的任何问题负责。

注:若iBeacon的设备厂商希望支持微信“摇一摇·周边“并加入上述参考表格,请参考以下步骤:
1.确认本iBeacon支持设备ID可更改(即不是一次性写入永久不能更改);
2.自行设置测试iBeacon ID,测试“摇一摇·周边”是否能正常使用。

(测试ID为UUID:FDA50693-A4E2-4FB1-AFCF-C6EB0764 7825,Major:10,Minor:7);
3.邮件联系,邮寄样品供项目组确认支持“摇一摇·周边“;
4.若有商户反馈,上述表格中的设备在使用“摇一摇·周边”过程中存在问题,确认无误后将从参考表格中删除。

4.2如何预估需要的设备数量?
请根据设备厂商提供发射覆盖范围进行估计。

一般来说,在空旷场所,一个设备可覆盖约30-50米的半径;(6976966@扣扣.c om注明百度文库咨询iBeacon)在室内场所,由于有遮
挡,一个设备最大可以覆盖约10-20米的半径范围,但也取决于iBeacon设备的发生功率,门店格局、墙面和玻璃反射等情况,具体请咨询设备厂商。

另外,iBeacon可以灵活设置发射范围,从几十厘米到几十米。

建议根据业务实际需求进行发射范围的设置,以达到更好的使用效果。

4.3如何配置设备ID?
A.若设备商提供设备ID配置服务,可将设备ID提供给您的设备供应商,并由供应商帮助您进行设备配置;
B.若设备商不提供配置服务,可要求设备供应商提供配置设备ID的App,根据APP指引说明自行配置;
C.此外,苹果iOS系统用户可以下载蓝牙配置软件进行配置,具体方法请参照其帮助文档。

但由于有些设备生产商会对其生产设备进行加密,并非所有蓝牙发射设备均可通过该App进行配置,具体请询问相应设备供应商。

暂未发现Android系统有足够灵活易用的配置App。

4.4多个设备可以用同一个设备ID吗?
A.一个设备ID可以用在多个设备上,但这些设备将会被看作是一个设备,只能指向同样的URL。

B.但是,平台不建议多个设备使用同一个设备ID。

原因一,不同位置的设备设置不同的设备ID,能够清晰获取用户和活动在不同位置的数据,有利于追踪数据分析;
原因二,平台规则要求设备必须在固定场所使用。

多个设备一个ID会造成平台运营监控预警,可能会导致ID失效,影响商户的正常运营活动。

4.5不同设备可配置同一个活动页面(URL)吗?
可以。

4.6设备部署有什么建议?
A.设备部署位置:建议部署在较高,且无人阻挡的位置,不要布置在封闭角落。

固体对设备信号阻挡严重;
B.设备部署间距:对于要求摇出单个产品相关信息的iBeacon 设备,建议部署间距在5米以上。

否则定位有一定误差,很难精准定位到最近的产品;
C.测试:建议部署后用相关APP在各个角度测试是否能检测到信号,或者使用“摇一摇·周边”来确认是否可以识别到信号;
五、其它
