How Does a Portable WiFi Hotspot Work?
It uses a wired network or a wireless internet chip (SIM card) provided by cellular carriers to create a WiFi hotspot, allowing various network terminals to connect to the internet through this WiFi signal.
What Are the Differences Between a Portable WiFi Hotspot and a Phone Hotspot?
Frequently using your phone as a hotspot significantly impacts battery life and overall phone longevity. Additionally, the phone often overheats, becoming very laggy; portable WiFi hotspots do not have these issues.
In some cases, the data connection on a phone drops when a call comes in. If other connected devices are handling critical tasks, this interruption could lead to data loss and potential damages.
A phone typically needs to be carried with you; once it leaves, the network connection for other devices is interrupted.
The number of connectable devices is fewer than a portable WiFi hotspot. A phone theoretically supports a maximum of 3-4 devices, while a portable WiFi hotspot theoretically supports up to 10.
Portable WiFi hotspots have stronger signal reception and amplification capabilities, providing wider coverage.
The IoT data plans used by portable WiFi hotspots are cheaper.
What Aspects Reflect the Quality Differences in Portable WiFi Hotspots?
Chipset – Undoubtedly, the chipset is the heart of the whole solution. Mainstream chipset manufacturers include Huawei’s Balong, Qualcomm, Marvell (acquired by ASR) – and Vimicro.
Solution Companies – The chipset is just the heart; building a PCBA around it that delivers strong signal transmission/reception, stable power consumption, and excellent performance is no simple task. It requires significant time and a strong R&D team.
Components – Including wafers, crystal oscillators, capacitors, etc. Top-tier components mainly come from US, Taiwanese, and Japanese manufacturers, such as SKYWORKS and Murata. There are also some first-tier domestic manufacturers, mainly those within Huawei’s supply chain.
What Are the Source Manufacturers and Sub-brand Classifications of Portable WiFi Hotspots?
Huawei (Balong solution) / ZTE (Vimicro solution) / Nuoxing (ASR solution) / Xfwei (Vimicro/Qualcomm recycled chip solution) / Others (Qualcomm solution)
Please note: DO NOT! DO NOT! DO NOT! Choose devices that don’t require a SIM card or real-name registration! These are colloquially known in the industry as “leek harvesters” (scams targeting unsuspecting users).
Is the Internet Speed of a Portable WiFi Hotspot Fast?
Here, you need to understand the unit conversion: 8 Mbps = 1 M/s. I believe you have all subscribed to home broadband; the advertised “100 Megabit broadband” is actually 100 Mbps, which is equivalent to 12.5 M/s.
Okay, let’s continue.
Portable WiFi hotspots have theoretical upload/download speed limits. Take the mainstream Cat4 devices on the market (often advertised as 4G+ in many stores); their theoretical upload/download speeds are 50/150 Mbps, which translates to the more familiar actual download speeds of 6.25/18.75 M/s.
The actual upload/download speed of the SIM card is determined by the carrier’s policy. If there’s no speed limit, the portable WiFi’s speed limit is the theoretical 6.25/18.75 M/s mentioned above.
There is a lot of misleading information in product details on TM and JD. For example, when they state “150 speed” here, would you think it means a download speed of 150 M/s?
About the SIM Cards
The market is chaotic, a mixed bag of good and bad. Countless scams from SIM card resellers make consumers shudder at the mention of “cards.” Let me explain some common traps so you can avoid being deceived. In the latter half of 2020, the “Card Cut Action” jointly launched by the Ministry of Public Security and the Ministry of Industry and Information Technology achieved good results; many SIM resellers ran off early, and quite a few ended up in jail
