[操作疑難] 請教Aircard澳水790s與港行790分別

Aircard澳洲水貨叫790s,佢同港行790有接收頻道分別,但我呢方面好膚淺,上網睇嘅資料又明啲唔明啲,向各師兄姐救教
1) 在地區方面,兩隻分別能支持哪些國家?
2) 在速度方面,以香港來說,兩隻在支援香港各電訊商的表現是否會有不同?

Netgear Aircard 790s is already available for Australia network provider Telstra and named Telstra WiFi 4G Advanced II.

再看octopusman師兄的各個電訊商測速,開始搞得清楚啲啲Band幾/MHz嘢

因為實際諗緊自己係咪要淘返隻澳水790S應付屋企同埋外出wifi需要...如蒙呢度師兄姐教路就唔使貢糾結鳥

啱啱用咗數記傭卡4G半日sim就嚟一個月...又希望隻蛋兼容到大部份香港電訊公司嘅sim...再支援到其他鄰近國家就係Bonus

    屋企就買隻華為插Sim router 啦,好似5百幾

睇過Aircard比790s早一期嘅model,應該係782s,宜家人仔310蚊好似幾好價,師兄們認為實際用途上如果多喺香港用數記及CSL的3G及4G 儲值sim話,可以從兩個型號的spec中估計到兩者性能嗎?我好有心學但身邊朋友冇人識呢!

782s:
Bands
4G LTE band 900 (B8) / 1800 (B3) /2100 (B1) / 2600 (B7) w/2x2 MIMO
FDD-LTE Category 4
Rel. 10 Carrier Aggregation: 900 (B8) / 1800 (B3)
DC-HSPA+ /tri-band 3G 850/900/1900/2100 MHz
Dual-band 2.4 GHz / 5 GHz WiFi support

以下文章有講兩者比較:
http://4gpocketwifi.blogspot.hk/ ... ar-aircard.html?m=1

裡面話:
Based on Qualcomm Qualcomm MDM9225 & WTR1605L chipset, Aircard 782s could support 4G LTE Band 1/3/7/8 and the peak download speed up to 150mbps. The Aircard 790s is on Qualcomm MDM9230, it could support multiple LTE bands 1/3/7/8/28 with peak download speed to 300Mbps, which is double speed than Aircard 782s. They are both back compatible with qual-bands UMTS/WCDMA networks, and GSM/EDGE network is also supported.     As a 4G mobile router, Netgear 782s could support up to 10 wireless terminals simultaneously. The Aircard 790s is more powerful on this function, up to 15 wireless users could be connected at the same time. Aircard 790s supports WLAN 802.11 ac which is missed in 782S. But dual-band WiFi and 2 X 2 MIMO are both available on the two mobile routers. And they both use Micro SIM(3FF Format).

咁兩者chipset係咪性能好有分別?另外,WLAN 802.11 ac對我講嘅實際使用主要插數碼通及CSL 3G 4G 儲值sim有冇大作用呢?

790s CA 只有 1800+2600 同 2600+2600 香港能用(香港無700)

你已經確定電訊商俾儲值卡用戶用佢哋個網行 CA / 4G+ 了嗎?

唔俾的話,150 定 300 對用家來説都無大分別,因為電訊商已限最高速
而此最高速,就是指2011/2012年開始提供 4G 時的業界普遍標準

至於 11.ac 就要睇接收設備(你部電話/電腦)的 WiFi 有無 11.ac (假設兩端接收距離短,無牆阻隔暢通無阻)
如果你的設備舊到連 ac 都無,仲係行 N 的話,又係得物無所用

TOP

再根據師兄指教向著11.ac爬文,自己連家人所用裝置只得iPhone 6s+係11ac,所以連同師兄提點嘅上半部分,應該790s對我現在情況來說是不適宜買入了!

說實話,沒有 CA/4G+
782s 亦是得物無所用(指速度上未能發揮全能)
電量,接收訊號能力這些就有太多外在因素影響,都真係要用過先知,我都唔敢話新嘅 chipset 接收能力同電量方面一定好過舊的
都真係要睇多啲用家回報參考下先好的

其實集中想搵隻高通嘅,但根據以下嘅型號逐個睇就覺得Aircard優先選

有人借咗隻澳水790s俾我,試了幾天,整體性能不錯尤其是可以2.4G和5G一同使用,有得直接touch mon 做基本設定。。。但因就算係水貨都唔平,加上以我用途嚟講,得物無所用,所以在要還返比人之前,昨晚決定買咗隻tp m7350 v3, 行貨有18個月保,$560

昨晚charge完電,啱啱試,發現驚喜!呢兩日試真啲先!
